Lineage Announces Pipeline Expansion to Include Auditory Neuronal Cell Therapy for Treatment of Hearing Loss - Galveston County Daily News

Spinal Cord Stem Cells Comments Off on Lineage Announces Pipeline Expansion to Include Auditory Neuronal Cell Therapy for Treatment of Hearing Loss – Galveston County Daily News | March 22nd, 2022

All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. Visit our coronavirus hub and follow our live updates page for the most recent information on the COVID-19 pandemic.

A recent study in Nature found subtle changes in the brains of people with mild to moderate COVID-19 after the initial 4 weeks or acute phase of a SARS-CoV-2 infection. The study showed that individuals with SARS-CoV-2 showed greater brain tissue damage and shrinkage of brain regions at an average of 4.5 months after their COVID-19 diagnosis.

Dr. Maxime Taquet, a senior research fellow at the University of Oxford, who was not involved in the study, said: It is well established that [SARS-CoV-2] infection is associated with subsequent risks of neurological and psychiatric problems in some people, including brain fog, loss of taste and smell, depression, and psychosis. But why this occurs remains largely unknown.

This study starts to shed light on this important question by showing that brain regions connected to the smell center of the brain can shrink after COVID-19 in some people.

The studys co-author, Professor Naomi Allen, chief scientist at UK Biobank, noted, [This] is the only study in the world to be able to demonstrate before versus after changes in the brain associated with SARS-CoV-2 infection.

Neurological symptoms are common both during and after the acute phase of a SARS-CoV-2 infection. Previous studies examining changes in the brain underlying these neurological symptoms have mostly focused on people with acute COVID-19.

The small number of studies assessing brain changes after the acute phase of a SARS-CoV-2 infection lacked access to brain imaging data before the infection. Consequently, some of the differences observable in these studies could be due to brain anomalies or risk factors that existed before the infection.

Researchers conducted the present study to distinguish brain anomalies relating to COVID-19 from those that may occur due to preexisting risk factors. Moreover, the study used multiple types of brain scans to assess brain changes in many individuals, facilitating the identification of subtle brain anomalies associated with the SARS-CoV-2 infection.

In the present study, the researchers used data from the UK Biobank, a large database containing medical information, including brain imaging data, from individuals in the United Kingdom.

Specifically, they used imaging data collected from 785 people using different brain scans before and after the onset of the COVID-19 pandemic. This included 401 participants with a SARS-CoV-2 infection between the two scans and 384 control adults without a COVID-19 diagnosis.

The scientists matched participants in the two groups for age, sex, ethnicity, and the duration between the two brain scans. The average duration between the COVID-19 diagnosis and the second set of brain scans was 141 days.

The researchers used software programs to analyze the raw brain imaging data and extract quantifiable features, called image-derived phenotypes (IDPs). Each IDP measures a specific brain structure or function, such as the change in brain region activity while performing a task or the volume of a specific brain structure.

In the present study, the researchers measured changes in over 2,500 IDPs for each individual.

A loss of smell or olfaction is observable in most individuals with a SARS-CoV-2 infection, including after the acute phase. Therefore, the researchers focused on brain regions either directly involved in processing olfactory information or those connected to the olfactory system.

They found a greater reduction in gray matter volume and a greater increase in tissue damage markers in specific brain regions associated with the olfactory system in participants with SARS-CoV-2 compared with controls. The gray matter comprises mainly of cell bodies of nerve cells and is involved in information processing.

There was also a greater loss of gray matter across the entire brain and an increase in the volume of cerebrospinal fluid in participants with a SARS-CoV-2 infection.

In other words, besides changes in brain regions associated with olfaction, there were global changes in the brains of participants with SARS-CoV-2. Notably, these brain anomalies were observable in individuals with mild to moderate COVID-19.

Examining differences in cognitive function, the researchers found that the participants with SARS-CoV-2 showed deficits in executive function, which encompasses higher-level cognitive functions such as thinking, reasoning, and decision-making.

Additionally, there was a correlation between a lower performance in the executive function test and atypical brain changes in a part of the cerebellum known to be involved in cognition.

These findings might help explain why some people experience brain symptoms long after the acute infection. The causes of these brain changes, whether they can be prevented or even reverted, as well as whether similar changes are observed in hospitalized patients, in children and younger adults, and in minority ethnic groups, remain to be determined, said Dr. Taquet.

However, the researchers noted that they did not have data on whether the participants with a SARS-CoV-2 infection had symptoms of long COVID. They were also unable to assess the association between the brain anomalies and potential long COVID symptoms.

COVID-19: Even mild to moderate infection may cause brain anomalies - Medical News Today

Spinal Cord Stem Cells Comments Off on COVID-19: Even mild to moderate infection may cause brain anomalies – Medical News Today | March 22nd, 2022

With its tail flipping rhythmically from side to side, this strange synthetic fish scoots around in its salt and glucose solution, using the same power as our beating hearts.

This nifty miniaturized circulatory system, developed by scientists at Harvard and Emory universities, can keep swimming to the beat for more than 100 days.

The inventors have high hopes for the strange little device, composed of living heart muscle cells (cardiomyocytes) grown from human stem cells.

The creation of the 'biohybrid' fish focuses on two key regulatory features of our hearts: their ability to function spontaneously, without need for conscious input (automaticity); and messaging initiated by mechanical motion (mechanoelectrical signaling).

This insights learned from the research will hopefully allow researchers to more closely examine these aspects in heart diseases.

"Our ultimate goal is to build an artificial heart to replace a malformed heart in a child," saysHarvard University bioengineer Kevin Kit Parker.

While it's straightforward enough to create something that may look like a heart, making something that actually functions like one is a much harder challenge. The wriggling fishbot is a big step towards this, building on previous work using rat heart muscles to build a jellyfish biohybrid pump and a cyborg stingray.

"I could build a model heart out of Play-Doh, it doesn't mean I can build a heart,"explainsParker.

"You can grow some random tumor cells in a dish until they curdle into a throbbing lump and call it a cardiac organoid. Neither of those efforts is going to, by design, recapitulate the physics of a system that beats over a billion times during your lifetime while simultaneously rebuilding its cells on the fly.

"That is the challenge. That is where we go to work."

With two layers of cardiomyocytes on each side of the tail fin, the biohybrid fish is built to be autonomous it can self-perpetuate its own movement.

When one side squeezes tight, the other side is stretched, triggering a feedback mechanism that causes the stretched side to contract and then trigger the same mechanism on the other side in an ongoing cycle.

This system of asynchronous muscle contractions is based on insect flight muscles.

Each contraction automatically triggers the other muscle pair to contract. (Lee et al., Science, 2022)

The physical bending is the mechanical motion that activates the electrical signal forming ion channels in the muscles. These ion channels trigger the muscles to activate and contract.

Exposing the system to streptomycin and gadoliniumknown to disrupt ion channels in musclesended up decreasing swimming speeds and breaking the relationship between the mechanical stretching and triggering of the next contraction on the other side. This confirmed the ion channels were indeed involved with the rhythmic contractions.

"By leveraging cardiac mechano-electrical signaling between two layers of muscle, we recreated the cycle where each contraction results automatically as a response to the stretching on the opposite side," saysHarvard University bioengineer Keel Yong Lee.

"The results highlight the role of feedback mechanisms in muscular pumps such as the heart."

Parker and colleagues also integrated a pacemaker-like system into the biohybrid: an isolated cluster of cells that control the frequency and coordination of these movements.

"Because of the two internal pacing mechanisms, our fish can live longer, move faster, and swim more efficiently than previous work," explainsbiophysics researcherSung-Jin Park, the co-first author of the study.

The tissue wide contractions of the biohybrid fish are comparable to the zebrafish that the biohybrid is modeled after more efficiently propelling the little device around than mechanical robotic systems.

"Rather than using heart imaging as a blueprint, we are identifying the key biophysical principles that make the heart work, using them as design criteria, and replicating them in a system, a living, swimming fish, where it is much easier to see if we are successful," says Parker.

This research was published in Science.

Relatlimab is the third immune checkpoint inhibitor from Bristol Myers Squibb, adding to the Company's growing and differentiated oncology portfolio

Bristol Myers Squibb (NYSE: BMY) today announced that Opdualag TM (nivolumab and relatlimab-rmbw), a new, first-in-class, fixed-dose combination of nivolumab and relatlimab, administered as a single intravenous infusion, was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult and pediatric patients 12 years of age or older with unresectable or metastatic melanoma. 1 The approval is based on the Phase 2/3 RELATIVITY-047 trial, which compared Opdualag (n=355) to nivolumab alone (n=359). 1,2

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20220304005561/en/

Opdualag Logo, Bristol Myers Squibb

The trial met its primary endpoint, progression-free survival (PFS), and Opdualag more than doubled the median PFS when compared to nivolumab monotherapy, 10.1 months (95% Confidence Interval [CI]: 6.4 to 15.7) versus 4.6 months (95% CI: 3.4 to 5.6); (Hazard Ratio [HR] 0.75; 95% CI: 0.62 to 0.92, P =0.0055). 1 The Opdualag safety profile was similar to that previously reported for nivolumab. 1,2 No new safety events were identified with the combination when compared to nivolumab monotherapy. 1,2 Grade 3/4 drug-related adverse events were 18.9% in the Opdualag arm compared to 9.7% in the nivolumab arm. 2 Drug-related adverse events leading to discontinuation were 14.6% in the Opdualag arm compared to 6.7% in the nivolumab arm. 2

"Since the approval of the first immune checkpoint inhibitor more than 10 years ago, we've seen immunotherapy, alone and in combination, revolutionize the treatment of patients with advanced melanoma," said F. Stephen Hodi, M.D., director of the Melanoma Center and the Center for Immuno-Oncology at Dana-Farber Cancer Institute. 3 "Today's approval is particularly significant, as it introduces an entirely new combination of two immunotherapies that may act together to help improve anti-tumor response by targeting two different immune checkpoints LAG-3 and PD-1." 1,2

Opdualag is associated with the following Warnings & Precautions: severe and fatal immune-mediated adverse reactions (IMARs) including pneumonitis, colitis, hepatitis, endocrinopathies, nephritis with renal dysfunction, dermatologic adverse reactions, myocarditis and other immune-mediated adverse reactions; infusion-related reactions; complications of allogeneic hematopoietic stem cell transplantation (HSCT); and embryo-fetal toxicity. 1 Please see Important Safety Information below.

"While we have made great progress in the treatment of advanced melanoma over the past decade, we are committed to expanding dual immunotherapy treatment options for these patients," said Samit Hirawat, chief medical officer, global drug development, Bristol Myers Squibb. 3 "Inhibiting LAG-3 with relatlimab, in a fixed-dose combination with nivolumab, represents a new treatment approach that builds on our legacy of bringing innovative immunotherapy options to patients. The approval of a new medicine that includes our third distinct checkpoint inhibitor marks an important step forward in giving patients more options beyond monotherapy treatment."

Lymphocyte activation gene-3 (LAG-3) and programmed death-1 (PD-1) are two distinct inhibitory immune checkpoints that are often co-expressed on tumor-infiltrating lymphocytes, thus contributing to tumor-mediated T-cell exhaustion. 2 The combination of nivolumab (anti-PD-1) and relatlimab (anti-LAG-3) results in increased T-cell activation compared to the activity of either antibody alone. 1 Relatlimab (in combination with nivolumab) is the first LAG-3-blocking antibody to demonstrate a benefit in a Phase 3 study. 1 It is the third checkpoint inhibitor (along with anti-PD-1 and anti-CTLA-4) for Bristol Myers Squibb.

"Today's approval is exciting news and offers new hope to the melanoma community. The availability of this treatment combination may enable patients to potentially benefit from a new, first-in-class dual immunotherapy," said Michael Kaplan, president and CEO, Melanoma Research Alliance.

The FDA-approved dosing for adult patients and pediatric patients 12 years of age or older who weigh at least 40 kg is 480 mg nivolumab and 160 mg relatlimab administered intravenously every four weeks. 1 The recommended dosage for pediatric patients 12 years of age or older who weigh less than 40 kg, and pediatric patients younger than 12 years of age, has not been established. 1

This application was approved under the FDA's Real-Time Oncology Review (RTOR) pilot program, which aims to ensure that safe and effective treatments are available to patients as early as possible. 4 The review was also conducted under the FDA's Project Orbis initiative, which enabled concurrent review by the health authorities in Australia, Brazil and Switzerland, where the application remains under review.

About RELATIVITY-047

RELATIVITY-047 is a global, randomized, double-blind Phase 2/3 study evaluating the fixed-dose combination of nivolumab and relatlimab versus nivolumab alone in patients with previously untreated metastatic or unresectable melanoma. 1,2 The trial excluded patients with active autoimmune disease, medical conditions requiring systemic treatment with moderate or high dose corticosteroids or immunosuppressive medications, uveal melanoma, and active or untreated brain or leptomeningeal metastases. 1 The primary endpoint of the trial is progression-free survival (PFS) determined by Blinded Independent Central Review (BICR) using Response Evaluation Criteria in Solid Tumors (RECIST v1.1). 1 The secondary endpoints are overall survival (OS) and objective response rate (ORR). 1 A total of 714 patients were randomized 1:1 to receive a fixed-dose combination of nivolumab (480 mg) and relatlimab (160 mg) or nivolumab (480 mg) by intravenous infusion every four weeks until disease progression or unacceptable toxicity. 1

Select Safety Profile From RELATIVITY-047

Adverse reactions leading to permanent discontinuation of Opdualag occurred in 18% of patients. 1 Opdualag was interrupted due to an adverse reaction in 43% of patients. 1 Serious adverse reactions occurred in 36% of patients treated with Opdualag. 1 The most frequent (1%) serious adverse reactions were adrenal insufficiency (1.4%), anemia (1.4%), colitis (1.4%), pneumonia (1.4%), acute myocardial infarction (1.1%), back pain (1.1%), diarrhea (1.1%), myocarditis (1.1%), and pneumonitis (1.1%). 1 Fatal adverse reactions occurred in three (0.8%) patients treated with Opdualag and included hemophagocytic lymphohistiocytosis, acute edema of the lung, and pneumonitis. 1 The most common (20%) adverse reactions were musculoskeletal pain (45%), fatigue (39%), rash (28%), pruritus (25%), and diarrhea (24%). 1 The Opdualag safety profile was similar to that previously reported for nivolumab. 1,2 No new safety events were identified with the combination when compared to nivolumab monotherapy. 1,2 Grade 3/4 drug-related adverse events were 18.9% in the Opdualag arm compared to 9.7% in the nivolumab arm. 2 Drug-related adverse events leading to discontinuation were 14.6% in the Opdualag arm compared to 6.7% in the nivolumab arm. 2

About Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. 5 Metastatic melanoma is the deadliest form of the disease and occurs when cancer spreads beyond the surface of the skin to other organs. 5,6 The incidence of melanoma has been increasing steadily for the last 30 years. 5,6 In the United States, approximately 99,780 new diagnoses of melanoma and about 7,650 related deaths are estimated for 2022. 5 Melanoma can be mostly treatable when caught in its very early stages; however, survival rates can decrease as the disease progresses. 6

OPDUALAG INDICATION

Opdualag TM (nivolumab and relatlimab-rmbw) is indicated for the treatment of adult and pediatric patients 12 years of age or older with unresectable or metastatic melanoma.

OPDUALAG IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions (IMARs) listed herein may not include all possible severe and fatal immune-mediated adverse reactions.

IMARs which may be severe or fatal, can occur in any organ system or tissue. IMARs can occur at any time after starting treatment with a LAG-3 and PD-1/PD-L1 blocking antibodies. While IMARs usually manifest during treatment, they can also occur after discontinuation of Opdualag. Early identification and management of IMARs are essential to ensure safe use. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying IMARs. Evaluate clinical chemistries including liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected IMARs, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue Opdualag depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if Opdualag requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose IMARs are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

Opdualag can cause immune-mediated pneumonitis, which may be fatal. In patients treated with other PD-1/PD-L1 blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.7% (13/355) of patients receiving Opdualag, including Grade 3 (0.6%), and Grade 2 (2.3%) adverse reactions. Pneumonitis led to permanent discontinuation of Opdualag in 0.8% and withholding of Opdualag in 1.4% of patients.

Immune-Mediated Colitis

Opdualag can cause immune-mediated colitis, defined as requiring use of corticosteroids and no clear alternate etiology. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis.

Immune-Mediated Myocarditis

Opdualag can cause immune-mediated myocarditis, which is defined as requiring use of steroids and no clear alternate etiology. The diagnosis of immune-mediated myocarditis requires a high index of suspicion. Patients with cardiac or cardio-pulmonary symptoms should be assessed for potential myocarditis. If myocarditis is suspected, withhold dose, promptly initiate high dose steroids (prednisone or methylprednisolone 1 to 2 mg/kg/day) and promptly arrange cardiology consultation with diagnostic workup. If clinically confirmed, permanently discontinue Opdualag for Grade 2-4 myocarditis.

Myocarditis occurred in 1.7% (6/355) of patients receiving Opdualag, including Grade 3 (0.6%), and Grade 2 (1.1%) adverse reactions. Myocarditis led to permanent discontinuation of Opdualag in 1.7% of patients.

Other Immune-Mediated Adverse Reactions

The following clinically significant IMARs occurred at an incidence of ardiac/Vascular: pericarditis, vasculitis; Nervous System: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr syndrome, nerve paresis, autoimmune neuropathy; Ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other IMARs, consider a Vogt-Koyanagi-Haradalike syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: pancreatitis including increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: myositis/polymyositis, rhabdomyolysis (and associated sequelae including renal failure), arthritis, polymyalgia rheumatica; Endocrine: hypoparathyroidism; Other (Hematologic/Immune) : hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

Infusion-Related Reactions

Opdualag can cause severe infusion-related reactions. Discontinue Opdualag in patients with severe or life-threatening infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild to moderate infusion-related reactions. In patients who received Opdualag as a 60-minute intravenous infusion, infusion-related reactions occurred in 7% (23/355) of patients.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 receptor blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1 receptor blocking antibody prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action and data from animal studies, Opdualag can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with Opdualag for at least 5 months after the last dose of Opdualag.

Lactation

There are no data on the presence of Opdualag in human milk, the effects on the breastfed child, or the effect on milk production. Because nivolumab and relatlimab may be excreted in human milk and because of the potential for serious adverse reactions in a breastfed child, advise patients not to breastfeed during treatment with Opdualag and for at least 5 months after the last dose.

First Phase 3 Study To Demonstrate Statistically Significant Improvement in DFS in the Adjuvant Setting for Patients With Stage IB-IIIA NSCLC Regardless of PD-L1 Expression

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside the United States and Canada, the European Organisation for Research and Treatment of Cancer (EORTC) and the European Thoracic Oncology Platform (ETOP) today announced results from the pivotal Phase 3 KEYNOTE-091 trial, also known as EORTC-1416-LCG/ETOP-8-15 PEARLS. The study found that adjuvant treatment with KEYTRUDA significantly improved disease-free survival (DFS), one of the dual primary endpoints, reducing the risk of disease recurrence or death by 24% compared to placebo (hazard ratio [HR]=0.76 [95% CI, 0.63-0.91]; p=0.0014) in patients with stage IB (4 centimeters) to IIIA non-small cell lung cancer (NSCLC) following surgical resection regardless of PD-L1 expression. Median DFS was 53.6 months for KEYTRUDA versus 42.0 months for placebo, an improvement of nearly one year. These data are being presented today during a European Society for Medical Oncology (ESMO) Virtual Plenary and will be shared with regulatory authorities worldwide.

These are the first positive results for KEYTRUDA in the adjuvant setting for non-small cell lung cancer, and represent the sixth positive pivotal study evaluating a KEYTRUDA-based regimen in earlier stages of cancer, said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. KEYTRUDA has become foundational in the treatment of metastatic non-small cell lung cancer, and we are pleased to present these data showing the potential of KEYTRUDA to help more patients with lung cancer in earlier stages of disease. We thank the patients, their caregivers and investigators for participating in this study.

As previously announced, there was also an improvement in DFS for patients whose tumors express PD-L1 (tumor proportion score [TPS] 50%) treated with KEYTRUDA compared to placebo, the other dual primary endpoint; these results did not reach statistical significance per the pre-specified statistical plan (HR=0.82 [95% CI, 0.57-1.18]; p=0.14). Among these patients, median DFS was not reached in either arm. Additionally, a favorable trend in overall survival (OS), a key secondary endpoint, was observed for KEYTRUDA versus placebo regardless of PD-L1 expression (HR=0.87 [95% CI, 0.67-1.15]; p=0.17); these OS data are not mature and did not reach statistical significance at the time of this interim analysis. The trial will continue to evaluate DFS in patients whose tumors express high levels of PD-L1 (TPS 50%) and OS. The safety profile of KEYTRUDA in this study was consistent with that observed in previously reported studies.

Lung cancer is most treatable at earlier stages, and adding treatment after surgery may help reduce the risk of recurrence, said Professor Mary O'Brien, consultant medical oncologist and head of the Lung Unit at The Royal Marsden NHS Foundation Trust and professor of practice (medical oncology) at Imperial College London, as well as co-principal investigator. We are encouraged by these new Phase 3 data, as they represent the first time adjuvant immunotherapy has demonstrated a statistically significant and clinically meaningful improvement in disease-free survival for patients with stage IB-IIIA non-small cell lung cancer.

While significant advancements have been made in the treatment of metastatic non-small cell lung cancer, there remains an unmet need for patients with earlier stages of this disease, as up to 43% of them will experience disease recurrence following surgery, said Dr. Luis Paz-Ares, chair of the medical oncology department, Hospital Universitario Doce de Octubre, Madrid, Spain and co-principal investigator. The positive disease-free survival data observed in this study with the use of KEYTRUDA in the adjuvant setting has the potential to have important implications for how we treat patients with stage IB-IIIA non-small cell lung cancer.

In addition to KEYNOTE-091, five other pivotal trials evaluating a KEYTRUDA-based regimen in patients with earlier stages of cancer met their primary endpoint(s). These trials included: KEYNOTE-716 in stage IIB and IIC melanoma; KEYNOTE-054 in stage III melanoma; KEYNOTE-564 in renal cell carcinoma; KEYNOTE-522 in triple-negative breast cancer; and KEYNOTE-057 in Bacillus Calmette-Guerin (BCG)-unresponsive, high-risk, non-muscle invasive bladder cancer.

Merck has an extensive clinical development program in lung cancer and is advancing multiple registration-enabling studies, with research directed at earlier stages of disease and novel combinations. Key studies in earlier stages of NSCLC include KEYNOTE-091, KEYNOTE-671, KEYNOTE-867 and KEYLYNK-012.

Study Design and Additional Data From KEYNOTE-091

KEYNOTE-091, also known as EORTC-1416-LCG/ETOP-8-15 PEARLS, is a randomized, Phase 3 trial (ClinicalTrials.gov, NCT02504372) sponsored by Merck and conducted in collaboration with EORTC and ETOP evaluating KEYTRUDA compared to placebo for the adjuvant treatment of patients with stage IB (4 centimeters) to IIIA NSCLC following surgical resection (lobectomy or pneumonectomy) and with adjuvant chemotherapy when indicated. The dual primary endpoints are DFS in the overall population and in patients whose tumors express PD-L1 (TPS 50%). Disease-free survival is calculated as the time from randomization to the date of disease recurrence, occurrence of second primary lung cancer, occurrence of second malignancy, or death from any cause, whichever occurs first. The secondary endpoints include OS and lung cancer-specific survival (the time from randomization to date of death due to lung cancer specifically). The study randomized 1,177 patients (1:1) to receive either KEYTRUDA (200 mg intravenously [IV] every three weeks [Q3W] for one year or maximum 18 doses; n=590); or placebo (IV Q3W for one year or maximum 18 doses; n=587). The median number of doses was 17 for KEYTRUDA and 18 for placebo. As of data cut-off for this interim analysis (September 20, 2021), median time from randomization to data cut-off was 35.6 months (range, 16.5-68.0 months).

Grade 3 adverse events occurred in 34.1% of patients receiving KEYTRUDA and 25.8% of patients receiving placebo. Adverse events resulting in discontinuation of any treatment occurred in 19.8% of patients receiving KEYTRUDA and 5.9% of patients receiving placebo; there were four treatment-related deaths in the KEYTRUDA arm and no treatment-related deaths in the placebo arm.

About Lung Cancer

Lung cancer is the leading cause of cancer death worldwide. In 2020 alone, there were more than 2.2 million new cases and 1.8 million deaths from lung cancer globally. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for about 82% of all cases. In the U.S., the overall five-year survival rate for patients diagnosed with lung cancer is 24%, a 14% improvement over the last five years. Improving survival rates are due in part to earlier detection and screening, reduction in smoking, advances in diagnostic and surgical procedures as well as the introduction of new therapies.

About Mercks Research in Lung Cancer

Merck is advancing research aimed at transforming the way lung cancer is treated, with a goal of improving outcomes for patients affected by this deadly disease. Through nearly 200 clinical trials evaluating more than 36,000 patients around the world, Merck is at the forefront of lung cancer research. In advanced NSCLC, KEYTRUDA has four approved U.S. indications (see indications below), and is approved in advanced NSCLC in more than 95 countries. Among Mercks research efforts are trials focused on evaluating KEYTRUDA in earlier stages of lung cancer as well as identifying new combinations and coformulations with KEYTRUDA.

About Mercks Early-Stage Cancer Clinical Program

Building on the strong understanding of the role of KEYTRUDA in later-stage cancers, Merck is studying KEYTRUDA in earlier disease states, with approximately 20 ongoing registrational studies across multiple types of cancer.

About KEYTRUDA (pembrolizumab) Injection, 100 mg

KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,700 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

Severe and Fatal Immune-Mediated Adverse Reactions

KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the PD-1 or the PD-L1, blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of antiPD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.

Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.

Hepatotoxicity and Immune-Mediated Hepatitis

KEYTRUDA as a Single Agent

KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.

KEYTRUDA With Axitinib

First-line treatment of advanced RCC in combination therapy with axitinib (KEYNOTE-426)

KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT 3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT 3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT 3 ULN subsequently recovered from the event.

Immune-Mediated Endocrinopathies

All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Nephritis resolved in 56% of the 9 patients.

Immune-Mediated Dermatologic Adverse Reactions

KEYTRUDA can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has occurred with antiPD-1/PD-L1 treatments. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes. Withhold or permanently discontinue KEYTRUDA depending on severity. Immune-mediated dermatologic adverse reactions occurred in 1.4% (38/2799) of patients receiving KEYTRUDA, including Grade 3 (1%) and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 40% (15/38) of patients. These reactions led to permanent discontinuation in 0.1% (2) and withholding of KEYTRUDA in 0.6% (16) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 6% had recurrence. The reactions resolved in 79% of the 38 patients.

Other Immune-Mediated Adverse Reactions

The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received KEYTRUDA or were reported with the use of other antiPD-1/PD-L1 treatments. Severe or fatal cases have been reported for some of these adverse reactions. Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr syndrome, nerve paresis, autoimmune neuropathy; Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: Myositis/polymyositis, rhabdomyolysis (and associated sequelae, including renal failure), arthritis (1.5%), polymyalgia rheumatica; Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

Infusion-Related Reactions

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 0.2% of 2799 patients receiving KEYTRUDA. Monitor for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1 or Grade 2 reactions. For Grade 3 or Grade 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)

Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after antiPD-1/PD-L1 treatments. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between antiPD-1/PD-L1 treatment and allogeneic HSCT. Follow patients closely for evidence of these complications and intervene promptly. Consider the benefit vs risks of using antiPD-1/PD-L1 treatments prior to or after an allogeneic HSCT.

Increased Mortality in Patients With Multiple Myeloma

In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with an antiPD-1/PD-L1 treatment in this combination is not recommended outside of controlled trials.

Embryofetal Toxicity

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.

One of the most important sacrifices a person can make is to offer the gift of life to another. Especially if they dont know whos receiving the gift, and they have to give up something they may need like the marrow in their bones.

Donating bone marrow to someone who is in distress, and may die without a transplant, is a selfless act. Blood diseases, such as leukemia, are horrific, causing tiredness, infections, and pain. A bone marrow transplant replaces damaged or diseased blood forming cells, also called stem cells, with healthy stem cells.

Those in need of a bone marrow transplant are put on a waiting list, because they need to be matched by a donor. Fortunately, there is a registry for those willing to donate their bone marrow.

Caitlin Stone-Webber of Port Austin was willing. She registered to be a donor while in college.

Back in 2011, I was a student at Central Michigan University, Stone-Webber said. There was a student who had a form of leukemia. They were doing a bone marrow drive, testing anyone who was willing to go on the registry, to see if there was a match on campus.

She was not compatible, but her name remained on the registry.

Its an international registry, Stone-Webber said. There are a lot of different groups that help build up this registry.

Five years ago, Stone-Webber received word she had matched. She went through a process of confirmation. Something happened on the recipients end, so the process wasnt completed. Two years later, the same thing happened. Earlier this year, she was contacted again. This time, the donation went through.

Upon receipt of the notification that shed matched, Stone-Webber was required to undergo a physical. The donation process is tiring, and the donor needs to be in good health.

The physical included checking her veins.

Even though its bone marrow, it no longer has to be hip surgery, Stone-Webber said. They can do whats called peripheral cell donation.

Peripheral blood stem celldonation is a method of collecting blood-forming cells for the transplant. The same blood-forming cells that are found in bone marrow are also found in the circulating (peripheral) blood. It is a procedure called apheresis.

They take your blood from one arm, Stone-Webber said. It goes through a machine, takes out your stem cells, and goes back in your other arm.

In addition to the physical, she also had to have injections that raised her stem cell count.

You do four days of injections, Stone-Webber said. And then the day of the procedure, you receive injections, as well.

The injections leading up to the procedure were given at her home.

Because of my size, I actually had to have two shots each day, one in each arm, Stone-Webber said. The nurse would come in, take my vitals, give the shots and then wait to make sure there was no reaction.

Although some people work throughout this stage, Stone-Webber took time off.

So I was able to just go to bed, she said. I was very tired, and my bones hurt. Thats where your bodys creating these extra stem cells ... in your bones. I was very aware of where every bone in my body was, but not at the same time. The first day it was in my legs. They hurt. The second day it was in my hips. One day it was in my toes. It was the strangest thing.

It was a normal part of the process.

They say to prepare for that, that your bones are going to hurt, Stone-Webber said.

She was told to take Tylenol for pain, as well as, oddly enough, Claritin, which relieves allergies.

They said they dont really know what part of the (Claritin) makes it work, but it works, Stone-Webber said.

The procedure took place at a hospital, although Stone-Webber isnt allowed to say where.

When you donate to someone, you stay anonymous until a year from the donation date, she said. I had to sign a confidentially document saying I could talk about the procedure I can talk about my experience. But I cant talk about where I donated.

Details on the identity of the recipient are unknown to her.

I know gender, Stone-Webber said. I know age. I know country. And, I know the type of leukemia. I didnt know what country they were in until post donation. Thats something I thought was real cool about being able to donate right now, is that with the world the way it is, to be able to help someone without knowing their political affiliation, or religion. None of that mattered. I was just helping another person.

Due to the fact that the bone marrow registry is international there are also national registries potential donors should be aware they may have to travel if they match. Stone-Webbers expenses, including travel, food, and lodging, were covered by the nonprofit organization the donation was set up through.

I was never billed for anything, Stone-Webber said.

All it cost her was time and a little discomfort.

The way I looked at it is, anyone can be sick for four or five days in order to save someones life, Stone-Webber said.

The actual donation took place in the course of one day. She was hooked up to a machine that recycled her blood. Due to her size her veins werent large enough for the procedure Stone-Webber required a catheter to be inserted in her jugular vein.

I could feel the catheter when I swallowed, she said. And when they pulled it out, I could feel a little bit of discomfort. For a couple days afterward, there were times I was a little uncomfortable.

Once the procedure started, Stone-Webber was confined to a hospital bed. She was given medication that allowed her to remain still, so the machine could recycle her blood.

It went in and out the same port, she said. I was hooked up to the machine for five hours, and it cycled my blood through the machine four and a half times. It was kind of cool to think someone has invented this machine that can cycle blood. Because of the injections, my body was still making stem cells, so that machine could continue to get out everything this recipient could need.

A bone marrow transplant is beneficial to those receiving the new stem cells. In some cases it may even provide a cure for their disease.

Its mostly for blood-related cancers, Stone-Webber said. There may be other blood-related disorders and diseases that it could help with. In some cases the donation is a treatment to kind of stall things. In others, its a cure. I was told the day of the donation, that my donation would be a cure that when the patient received my donated stem cells, it would cure their leukemia providing its a successful donation and their body accepts it.

The bone marrow registry can be accessed through a number of nonprofit organizations, including http://www.dkms.org and http://www.bethematch.org, which Stone-Webber worked with.

As of now, she knows her stem cells have been received by the recipient, but has no idea of the outcome. At the end of the year required by her confidentiality agreement, she would like to know whether or not they were affective. After all, her stem cells are now in someone else.

I think we now connect in a different way than most people would, Stone-Webber said. I think I would like the opportunity to know how theyre doing.

That connection is a bone marrow transplant, the gift of life. Stone-Webber would do it again.

An article published in the journal Biomaterials shows that [emailprotected]2 nanoparticles (NPs) synthesized with a short bacteriophage-selected mesenchymal stem cell(MSC) targeting peptide allowed the MSCs to take up these NPs. NP-modified MSCs produced greatly improved therapy of Rheumatoid Arthritis(RA) using stem cells.

RA, which is marked by progressive joint degeneration andsynovial inflammation, is one ofthe primary widespread inflammatory arthritis thataffectsaround 1 % of the global population, however, it currently lacks an effective treatment.

Glucocorticoids (GCs), disease-modifying anti-rheumatic drugs (DMARDs) and non-steroidal anti-inflammatory drugs (NSAIDs)are the three maintypes of medicationscurrently used in clinical practice.

GCs and NSAIDscan help with joint pain and stiffness, but they may cause side effects such asheart problems, osteoporosis, infections andgastric ulcers.

Standard DMARDs, like methotrexate (MTX), can lessen swelling by inhibiting the synthesis of pro-inflammatory cytokines and have little effect on cartilage degeneration. MTX, on the other hand, has a short plasma half-lifeand a poor concentration of the drug in the inflammatory region of the body.

Other side effects may also include liver and kidney damage, bone marrow depletion, and gastrointestinal problems. Biological DMARDs have been rapidly developed in recent years, thoughtheir action slows the progression of structural damage by reducing inflammation and have issues including drug resistance and the potential to cause significant infections and malignant tumors.

Multilineage differentiation, inflammatory site and immunomodulationhoming are all features of MSCs. These distinctivecharacteristicsallowMSCs to become apotential treatmentfora variety ofinflammatory and degenerativediseases, including the treatment of RA,through cell therapy. Unfortunately, over 50 % of patients do not react to MSC treatment, and the therapeutic benefit of MSCs is only temporary.

Firstly, MSCs are susceptible to the inflammatory milieu and so lose their functions of immune-regulationwhen disclosed in an inflamed joint. Reactive oxygen species (ROS) are thought to be engaged in the inflammation development of RA and hence damaging to MSCs, as seen by the gradualdecline in the quantity of MSCs in RA patients' synovial fluid.

Secondly, while the direct impacts of MSCs on tissue regeneration in RA are unknown, an evidentclinical experiment found that MSC injections increased hyaline cartilage regeneration in RA patients. Nevertheless, the unregulated distinction of MSCs can alsoresult in the development of tumors andthe inability of cartilage repair.

As a result, it is important for an optimal stem cell strategy to include MSCs that have the ability to preserve their bio functions and chondrogenically develop to regenerate cartilage under the oxidative stress caused by RA.

According to thisstudy, RA therapy could be enhanced byshort targeting peptide-promoted nanomodification of MSCs. To begin with, [emailprotected]2 NPs wereproduced due to some of theirelements' appealing features. Mn and Cu both are critical trace components in the human body, and they play a keyrole in the production of natural Mnsuperoxide dismutase (SOD) and Cu-ZnSOD, respectively.

Cu and Mn can also encourage stem cell chondrogenesis. The study further explains the modification of [emailprotected]2 NPs with MSC-targeting peptides to increase the passage of the nanoparticles into MSCs since transporting nanomaterials into modifications of MSCs is still a difficult task.

To make [emailprotected]2/MET NPs, [emailprotected]2 NPs were injected with metformin. Lastly, MSCs were allowedto take up these NPs and utilizethem to effectively limit synovial inflammation and maintain cartilage structure, alleviating arthritic symptoms greatly.

This study demonstrates that VCMM-MCSs werecreated by engineering MSCs with catalase (CAT) and superoxide dismutase (SOD)- like activity using dynamically MSC-targeting [emailprotected]2/MET NPs.

The biological features of these cells required in stem cell treatment, such as chondrogenesis, anti-inflammation, cell migration, and increased survival under oxidative stress, were improved by VCMM-MCSs.

Consequently, the VCMM-MSCs injections reduced cartilage damage andsynovial hyperplasiain adjuvant-induced arthritis (AIA) as well as collagen-induced arthritis (CIA) models, substantially reducing arthritic symptoms. Since oxidative stress is present in numerous degenerative and inflammatory disorders, this strategy of altering MSCs with NPs could be applied to treat a number of other disorders as well as to achieve faster tissue healing using stem cell therapy.

London-based leukaemia patient Yvette Chin, 41, has just months to live unless a stem cell donor is found. PROVIDED TOCHINA DAILY

The family of a Chinese leukaemia patient in the United Kingdom has launched an urgent appeal calling for the East Asian community around the world to become stem cell donors.

Yvette Chin, 41, from London has acute lymphoblastic leukaemia, a rare aggressive blood cancer, and has just months to live unless a donor can be found.

Her brother, Colin Chin, 48, and sister-in-law Serena Chin are urging more people in the Chinese and East Asian community to register as stem cell donors to increase the chances of saving her life.

According to charity Anthony Nolan, which works in the areas of leukaemia and hematopoietic stem cell transplantation, 75 percent of UK patients will not find a matching donor in their families.

Only 72 percent of patients from white Caucasian backgrounds can find the best possible match from a stranger. This drops to 37 percent for patients from a minority ethnic background.

Yvette, who was diagnosed with the disease in May 2021, needs to have a stem cell transplant with a 90 percent genetic match.

The family hopes more people in the East Asian community in the UK and internationally can sign up to a bone marrow register to help Yvette and others in a similar position.

"Our family has registered but it's not enough. I hope if more people from the community know how quick and easy it is to do, and that it's literally lifesaving, we can find a match," Colin said.

"Not just for Yvette, but also for others who don't have time to wait. I'm asking for everyone to sign up and share #SwabForYvette on social media to spread awareness that we all have the power to save lives with a simple mouth swab."

Yvette's sister-in-law Serena hopes their campaign will help more people in ethnic minority groups gain a better understanding of what being a stem cell donor involves.

"When we looked into it, we realize Yvette isn't the only one in the community who needed this and that others are waiting for a donor, waiting for that second chance of life," she said. "Of course, we hope we find a match for Yvette, but I hope also we help save other people's lives as well who are in the same situation."

Yvette, a keen explorer who has scaled Mount Kilimanjaro, has been in and out of hospital for chemotherapy since her diagnosis last year. She took part in an experimental trial but in February she was told the trial had failed.

"After the trial, the leukaemia came back with so much ferocity and we still don't have a match, my brother wasn't a match and that was the reality that it was going to be difficult," Yvette said. "It feels like the stars have to align so much with me being in remission and finding a match."

Reshna Radiven, head of communications and engagement at DKMS UK, an international nonprofit bone marrow donor center, said ethnic minority communities are massively under-represented, especially the Chinese, Pakistani, Bangladeshi, Black-African and Black-Caribbean communities.

"There is an element of hesitancy, for some of the communities we know they don't trust the health system or the system generally in the countries that they're resident in," Radiven said. "But there is also a fundamental lack of awareness of the need for stem cell donors and the impact a stem cell donation can have for a cancer patient."

She added more work needs to be done to communicate and encourage people to become donors.

"You're very likely to find a match from a donor who is from the same ethnic community as you, so it's really important for all people to be represented in the register," Radiven said. "We offer the family and the patient hope, which is really significant when you're in a very difficult situation.

"In a world where we're trying to bridge the gap of inequality, we just want to get the word out there to encourage more bone marrow donations and blood too," Yvette said.

"I feel like the East Asian community has trepidation about doing that, so if they don't do it for me, then do it for someone else and bridge that stark statistic between our white Caucasian counterparts and everybody else."

Mixed-phenotype acute leukemia (MPAL) is a rare type of blood cancer. Typically, a doctor can classify the cancer as acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL), depending on the cells involved. However, MPAL presents with features of both AML and ALL.

Leukemia describes a cancer of the blood or bone marrow. There are many types of leukemia, and doctors typically classify them as either acute (sudden) or chronic (slow), depending on how quickly the cancer develops. They can then further classify these cancers depending on whether they affect myeloid or lymphocytic blood cells.

MPAL refers to a rare subtype of leukemia that displays no clear sign of origin and presents with features of both AML and ALL.

In this article, we will discuss MPAL leukemia, including the symptoms, diagnosis, treatment options, and outlook.

Mixed-phenotype acute leukemia (MPAL) is a rare type of acute leukemia where leukemia cells present with both myeloid and lymphocytic features. Some may also refer to this type of leukemia as acute leukemia of ambiguous lineage (ALAL), mixed-lineage leukemia, and acute undifferentiated leukemia.

In 2008, the World Health Organization (WHO) introduced the term MPAL to classify this group of blood cancers. Previously, the scientific community used other terms such as biphenotype acute leukemia to label these diseases.

A doctor may also further classify MPAL into bilineal or biphenotypic leukemia. The former refers to two separate populations of cells with myeloid and lymphoid origin, while the latter describes a single population of leukemia cells that express markers of both lymphoid and myeloid origin.

Some evidence suggests that the frequency of MPAL is 3%, while other research indicates that it accounts for roughly 25% of all acute leukemia diagnoses. MPAL can affect both children and adults.

As with other types of acute leukemia, the exact cause of MPAL is currently unknown. Some evidence suggests that MPAL may derive from alterations in blood stem cells that have the ability to undergo myeloid and lymphoid differentiation.

Research indicates that genetic alterations are associated with acute leukemias and may explain the abnormal development and maturation of white blood cells.

Certain genomic alterations may drive the biphenotypic expression in leukemia cells. Chromosome alterations that are often present in individuals with MPAL include Philadelphia chromosome and chromosome 11q23 abnormalities.

Potential risk factors for developing leukemia may include:

The symptoms of MPAL can occur suddenly and typically relate to problems with bone marrow. Symptoms can include:

Many of these symptoms are common to other conditions, including other types of leukemia. However, healthcare practitioners are aware of symptoms that may indicate MPAL leukemia and will request further testing if they think it is necessary.

Initially, doctors will likely use the same tools for diagnosing other forms of leukemia. These may include:

Due to the lack of consensus on the diagnostic criteria for MPAL, it can be difficult to diagnose the condition. The WHO diagnostic criteria provide a small list of specific lineage markers that can help diagnose MPAL.

Health experts use an immunophenotyping method, known as flow cytometry, on blood or bone marrow samples to identify these markers on leukemia cells.

This technique uses light to detect and measure the characteristics of cells. For an MPAL diagnosis, the sample will contain markers of both myeloid and lymphoid origin. This can also help guide if an AML or ALL treatment regimen will be more appropriate for a treatment plan.

If a doctor suspects an MPAL diagnosis, they will likely request genetic testing to identify the presence of genetic alterations, such as Philadelphia chromosome and chromosome 11q23 abnormalities. This is because a person with these alterations may require a more intensive treatment plan.

Treatment options for MPAL leukemia will vary depending on the diagnosis, age, and medical history. As MPAL leukemia is challenging to treat, the treatment plan is often intensive and usually starts quickly after diagnosis.

A 2018 systematic review and meta-analysis and a 2017 review both suggest that using a chemotherapy regimen for ALL or a combined ALL/AML regimen can result in a better outcome for people with MPAL leukemia than using chemotherapy that doctors use only for AML. A 2019 paper also suggests that ALL treatment may be preferable for treating MPAL.

A 2020 study notes that in cases of MPAL with a Philadelphia chromosome abnormality, the use of targeted therapy such as tyrosine kinase inhibitors can help to improve outcomes.

Doctors may consider other treatments if these options do not provide a satisfactory response. For example, they may use immunotherapies, which activate the immune system to detect and attack cancer cells. A doctor may also perform a stem cell transplant to eradicate any remaining leukemia cells in the bone marrow.

Historically, the outlook for individuals with MPAL has not been very positive. However, with more research and advances in treatment options, the outlook is improving. While it remains hard to predict the overall survival for those with MPAL, evidence suggests that factors that may predict a less positive outcome include:

A 2017 retrospective study suggested the three-year overall survival rate for MPAL was 56.3%, compared with the 5-year survival rate of 65% for leukemia in general. Like other acute leukemias, the quicker the diagnosis and treatment of MPAL, the higher the chance of recovery.

MPAL is a rare form of blood cancer that presents with clinical features of AML and ALL. As with other acute leukemias, the exact cause is unknown, but many cases are associated with genetic abnormalities. Due to its rarity and various diagnostic criteria, it can be a difficult condition to diagnose.

Treatment options vary depending on an individuals diagnosis, age, and medical history but may include chemotherapy, targeted therapy, immunotherapy, and stem cell transplants. While the outlook for MPAL is generally poorer than other leukemias, advances in research and treatments are improving outcomes.
