Basel, 29 April 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced new three-year data from the FIREFISH study, including one-year data from the open label extension, reinforcing the long-term efficacy and safety of Evrysdi® (risdiplam) in infants with symptomatic Type 1 spinal muscular atrophy (SMA). The data showed an estimated 91% of infants (n=58) treated with Evrysdi were alive after three years of treatment. The Evrysdi-treated infants continued to improve or maintain motor functions, including the ability to swallow, sit without support, stand with support and walk while holding on, between two and three years of treatment. Without treatment, children with Type 1 SMA are never able to sit without support. The study also showed overall continued reductions in serious adverse events (SAEs) and hospitalisations over time.

Stem cell transplants can effectively cure a wide range of diseases, from blood cancers to rare genetic disorders. They've been used for decades and are considered standard treatment for certain conditions.

But for a good number of patients, stem cell transplants are out of reach. Drug regimens used to prepare the body for a transplant are toxic and can cause serious side effects. The transplanted cells don't always "engraft," or take root in the bone marrow. Even when they do, patients' disease may linger or recur.

A biotech startup launching Wednesday with $50 million in funding hopes that, by combining cell, antibody and gene editing technologies, at least some of these problems can be overcome. Called Cimeio Therapeutics, the new company is led by a team of pharmaceutical industry veterans and an advisory board filled with scientific luminaries, including immunologist Jeffrey Bluestone and gene editing pioneer Fyodor Urnov.

Cimeio's approach involves "shielding" transplanted cells by genetically editing them in ways that allows paired immunotherapies to be safely used both before and after a transplant.

"We think that this can really unleash the power of hematopoietic stem cell transplant and make a lot more patients eligible for it," said Thomas Fuchs, Cimeio's CEO and a former Genentech executive.

The "shielding" technology used by Cimeio was developed in Switzerland at the laboratory of Lukas Jeker, a physician-scientist from Basel University Hospital who will join Cimeio as head of gene editing.

Jeker's lab discovered that protein receptors on the surface of cells could be genetically edited in such a way that prevented antibodies from binding to them, while leaving their function intact. In preclinical testing, these edits could cloak, or "shield," the cells from being depleted by antibody drugs and T cell therapies.

The work could have powerful implications for improving stem cell transplant and adoptive cell therapy, according to Fuchs.

Once a stem cell or T cell is shielded, a complementary immunotherapy could be used to either help ready patients for a transplant or to further treat disease afterwards, he said. "Maybe you could give a cycle or two of the paired immunotherapy, implant the shielded cells and then continue to administer the immunotherapy," he added.

If the shielding works as intended, Cimeio could develop treatments for conditioning that are more tolerable than the chemotherapy or radiation-based regimens currently in use. Shielding might also allow existing drugs that target cell proteins on healthy as well as diseased cells to be used more flexibly with transplants, such as to treat residual disease that lingers afterwards.

For example, Cimeio could engineer stem cells that are protected against binding via a protein called CD19 that's often the target for CAR-T therapies that treat lymphoma, but is also found on healthy B cells that help the immune system fight off threats.

"One benefit could be that you could prevent a lifetime of B cell depletion, which happens when you give a CAR-T," said Fuchs.

Cimeio was built from Jeker's lab by Versant Ventures at the company's "Ridgeline" incubator in Basel, which has previously produced companies like Monte Rosa Therapeutics and Black Diamond Therapeutics. The initial $50 million Versant provided will fund Cimeio through next year, said Alex Mayweg, a managing director at the venture firm and a Cimeio board member. Additional investors will be brought on later this year or early next, Mayweg said.

Cimeio will need the money, as its research and development plans are expansive. The company has identified four drug candidates already and envisions a dozen more behind those, said Fuchs. Its research spans blood cancers, rare genetic diseases and autoimmune disorders.

In some cases, Cimeio will develop paired immunotherapies to go with the shielded cells. In others, it will use existing treatments. Three of the first four candidates involve protecting hematopoietic stem cells, while the fourth involves T cells. The company hopes to begin human testing next year.

Cimeio plans to choose gene editing technologies based on the type of alteration it needs to make to shield cells. "Rather than building up an internal editing capability," Mayweg said, "we wanted to stay as flexible as possible."

That might mean partnerships or alliances with other companies, some of which have reached out to Cimeio already, according to Mayweg.

Cimeio is aided by a group of scientific advisers notable for their work in areas the company is focusing on. Urnov, of the University of California, Berkeley, is well known for his research in gene editing using zinc finger nucleases and CRISPR. Bluestone previously led the Parker Institute for Cancer Immunotherapy and is CEO of the cell therapy-focused biotech Sonoma Biotherapeutics.

Suneet Agarwal, a co-program leader of the stem cell transplant center at Boston Children's Cancer and Blood Disorders Center, is also on the advisory board, while Cimeio has a research collaboration in place with Matthew Porteus, a gene editing specialist at Stanford University.

About 20 people currently work at Cimeio directly, a number Fuchs expects will grow as the company's research advances. Another 15 are currently supporting Cimeio from Versant's Ridgeline group.

ABC24 talked with Randy Hutchinson from the Better Business Bureau of the Mid-South about a lawsuit against one company and what consumers need to watch out for.

MEMPHIS, Tenn. The Federal Trade Commission and Georgia Attorney General have sued the founders of a company they claim has made unsubstantiated claims its stem cell therapy can treat arthritis, joint pain, and other orthopedic ailments.

The company is called Stem Cell Institute of America. It claimed its treatments are comparable to or better than surgery, steroid injections, and painkillers. The FTC said the company charged up to $5,000 per injection. It said a related company taught chiropractors and other healthcare professionals how to offer stem cell therapy.

ABC24 talked with Randy Hutchinson from the Better Business Bureau of the Mid-South about the claims and what consumers need to watch out for.

So what are the facts about stem cells?

They're sometimes called the body's "master cells" because they develop into blood, brain, bones, and other organs.

Stem cells from bone marrow or blood are used to treat certain kinds of cancer and disorders of the blood and immune system. But other uses have not been properly studied and approved.

The FDA cites these potential risks from unproven treatments:

There could be safety risks even using a persons own stem cells.

Other claims by some companies

The FTC has also looked into companies claiming their stem cell therapies can treat Parkinson's, multiple sclerosis, COVID, and a host of other ailments. They're sometimes referred to as "regenerative medicine."

So what do consumers need to do?

Take miracle health care claims with a grain of salt.

Marc Howard was diagnosed with multiple myeloma. He will receive a transplant using his own cells later this year.

COLUMBUS, Ohio It all started with back pain that seemed to be progressively getting worse.

My back, the structure of my body, was like starting to deteriorate, and I could tell, he said. I'm tall, so when I started to lean over, and the pain and things of that nature, I'm like, yo, something's going on.

His longtime love Sonia Grant noticed, too. And she was right there to encourage him to get it checked.

When he did, doctors found holes in his spine where his bone had deteriorated. He had a vertebroplasty procedure to have those holes filled with bone cement. But that was not the end of his journey. In fact, it was really only the beginning.

After the surgery, he was okay for about a month, then I saw him (leaning) over again, and he couldnt get off the bed one day, Grant said. I said, uh uh, were going back up there (to the hospital). Theres something wrong.

And something was. Howard was diagnosed with multiple myeloma, a cancer that forms in the plasma cells.

I dont want to be the woe is me, Howard said. I want to be the success story for somebody, for the world to look at, like, that man went through a situation, and he made it.

And hes making it so far, with the help of Grant. Hes been doing weekly chemotherapy treatments and taking daily medication. Meanwhile, Grant is making sure hes eating his fruits and veggies and drinking plenty of water, too.

If youre not up to the challenge, I will help you get there, I will, Grant said. Because failure is just not a thing when it comes to fighting something like cancer. You gotta fight, you just gotta fight.

This fight will culminate with a major procedure later this fall via OhioHealths new Blood and Marrow Transplant Program. Howard will be one of the first patients to receive an autologous stem cell transplant, meaning the procedure will use his own cells.

Dr. Yvonne Efebera, the medical director for the program, explains this process is different than a procedure using donor cells.

BMT, blood and marrow transplant, is a process where, certain diseases require this, where non-functioning, deficient bone marrow or cancer cells are eliminated by giving high-dose chemotherapy, with or without radiation, and then replaced by new, healthy cells, Dr. Efebera said.

Shes been treating Howard throughout this process and points out that this is one of the benefits of the new program. Before, patients who needed transplants would have to be sent to other healthcare systems. Now, they can go from start to finish with the same clinical team.

Marc always wanted to be the first, she joked. Hes anxious to have his stem cells to be the first collected and the first admitted.

Both Howard and Grant are up to the challenge.

Its a battle, Grant said. Were halfway through the battle, and so, were going to get all the way to the end of the battle. Bruised, not broken. But were in the battle. But were going to get through it.

Investigators uncovered potential mechanisms of resistance to CD19-directed CAR T-cell therapy in patients with pediatric acute lymphoblastic leukemia.

Bone marrow samples from a trial examining CD19-directed CAR T-cell therapy helped investigators identify epigenetic biomarkers predicting resistance to therapy in pediatric acute lymphoblastic leukemia (ALL), according to a presentation from the 2022 American Association for Cancer Research (AACR) Annual Meeting.1

Investigators observed 3 key features of leukemia cells that do not respond to CAR T-cell therapy: hypermethylation of DNA, a stem cell-like phenotype and inherent plasticity, and decreased antigen presentation. These are independent of CD19 status and leukemia subtype, indicating a new predictive biomarker.

Whats most important about this is we can detect it prior to therapy in patient samples, so this highlights its potential as a biomarker for response, Katherine E. Masih, BS, an NIH-Cambridge scholar in the Genetics Branch, Center for Cancer Research at the National Cancer Institute, said in a press conference. We hope that eventually this can improve patient selection and eligibility for CD19 CAR T-cell therapy.

CD19 is a common target of CAR T cells, and resistance to treatment can occur even if patients continue to show CD19 expression. The investigators explored primary non-response (PNR) to CAR T-cell therapy, which occurs in 10% to 20% of patients and whose causes are not fully understood. Known reasons for non-response to CAR T cells include collection of dysfunctional T cells and decreased death cell receptors on the cell surface.2,3

The investigators used bone marrow samples from 14 participants in the PLAT-02 trial (NCT02028455) of CD19-directed CAR T-cell therapy for relapsed/refractory pediatric ALL.1 These samples included those of 7 patients who had a complete response to therapy and 7 who had no response. Non-response was defined as not achieving and maintaining minimal residual disease negativity at 63 days.

A multiomic analysis of the bone marrow included whole-exome sequencing, RNA sequencing of the bulk cells, single-cell RNA sequencing, array-based methylation analysis, and ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing).

In patients who went on to have PNR, investigators discovered epigenetic markers including 238 regions of hypermethylated DNA, which is associated with inactivated genes (P = 8.15 10-25). These regions are known to be activated in stem cells.

The ATAC-seq analysis showed increased accessibility of chromatin at regions linked to stem cell proliferation (normalized enrichment score [NES] = 2.31; P < .0001) and cell cycling (NES = 2.27; P < .0001), indicating inherent plasticity that may allow leukemia cells to adapt to resist CAR T-cell therapy.

Investigators found that the epigenetic differences did not lead to differences in phenotype of B cells between primary sensitive and PNR patients. However, PNR cells did show an increase in regions associated with hematopoietic stem cells and myeloid and lymphoid progenitors. In addition, investigators observed decreased antigen presentation and processing that could lead to lack of response in cells that still express CD19 (P = .0001).

These factors characterized a potential novel biomarker associated with PNR that investigators named Stem-Cell Epigenome with Multi-Lineage Potential (SCE-MLP). Masih acknowledged that the sample size of 14 patients was small and more research on SCE-MLPs link to PNR is needed. We would love to see this validated in a larger cohort with more cases of PNR that exist around the country, she said.

Another potential use of SCE-MLP could be to find ways to overcome resistance to CAR T-cell therapy by combining it with targeted therapies that disrupt these epigenetic factors for resistance.

Currently, the investigators hope that this research will be used to shape patient selection for CAR T-cell therapy and alternative therapies.

If we can reliably identify responders, perhaps through screening for SCE-MLP, we can prioritize less toxic targeted therapies for our patients and overall improve outcomes for children with this devastating disease, Masih said.

Salny Ehman, left, and Tom Ellison, the man whose life she saved through a bone marrow donation.

Penticton resident Salny Ehman saved a complete stranger's life, and hopes to inspire others to do the same.

Ehman, now 35, signed up to be a bone marrow donor at the age of 19, after watching her grandmother's sibling go through leukemia.

"She has a whole bunch of siblings, and one of them had blood cancer, and only she was a match. And the math of that blew me away, how likely is it to have a close relative that can help?" Ehman said.

"If it's that unlikely to have a match when you have that many siblings, then people need to sign up."

Ehman did just that. She registered with Canadian Blood Services, and a few months later, got a call that she was a match with an anonymous recipient signed up through an American service, fighting cancer and in need of bone marrow stem cells.

Despite not knowing who she was donating to, Ehman underwent the donation procedure, and then one year later, did the same thing again after learning the recipient's body had been rejecting the donated cells.

"One year after the second donation, we were both allowed to say yes, we would like to know the other person. And we both said yes, but I was living in Nova Scotia at the time," Ehman said, having learned her stem cell recipient, Tom Allison, lived in Seattle.

"The only information given to me about [my donor] was it was a 19 year old girl from Nova Scotia. And I thought, what's a 19 year old girl doing on a bone marrow registry for?" Allison said.

"Neither one of my boys were matches, and neither one of my brothers. So this seemed just a million to one chance for somebody out there with a match that's no relation to me."

Allison and Ehman ultimately got in touch and kept in touch for more than a decade.

"We would write each other letters over the years, and little postcards," Ehman said.

"And then I moved here [to Penticton] two years ago. So as soon as I moved here, I was like, 'Wow, I'm so close.' Just a quick drive, like three and a half hours away."

She and Allison, who is now in his 60s and healthy post-cancer, met up in person recently, and Ehman was thrilled to see him thriving thanks to her donation.

"Second to my daughters, [donating] was the best, best experience in my entire life. And to know that he was out there, and spending time with his family, his grandchildren, it really meant a lot. And it showed me what I was capable of," Ehman said.

She and Allison remain good friends, and she urges anyone who can help to either sign up to be a donor, or if they can't participate in that way, give financially to Canadian Blood Services.

"There's lots of opportunities to help that cause," she said.

Find out more about Canadian Blood Services and how you can help here, and learn how you can be the match that saves someone's life here.

ABSTRACT

Exosomes-related microRNAs (miRNAs) have been considered to be the significant biomarkers contributing to the development of atrial fibrillation (AF). We observed the implicit mechanism of exosomes-miR-148a derived from bone marrow mesenchymal stem cells (BMSCs) in AF. The AF cell and mice models were established firstly. QRT-PCR and Western blot analysis were applied to detect the expression of miR-148a, SPARC-associated modular calcium-binding protein 2 (SMOC2), Bcl-2, Bax, and caspase-3. BMSCs were separated from healthy mice and exosomes were obtained from BMSCs. BMSCs were transfected with mimics and inhibitor, and HL-1 cells were treated with mimics and pcDNA3.1. MTT assay were used to detect cell viability of cells. Flow cytometric analysis and TUNEL analysis were used for detecting cell apoptosis of cells. In our study, exosomes derived from BMSCs inhibited the development of AF, and miR-148a acted a vital role in this segment. SMOC2 was a target gene of miR-148a and promoted apoptosis of HL-1 cells. Additionally, miR-148a mimics decreased cellular apoptosis, eliminated SMOC2 expression, and elevated Bcl-2 expression in AF-treated cells. Collectively, miR-148a overexpressed in BMSC-exosomes restrained cardiomyocytes apoptosis by inhibiting SMOC2.

Three children are fighting for their lives and require stem cell transplants to cure their blood cancers and disorders.

Rayaan (four months), Emily (five months) and Neo (7) all share one commonality: being diagnosed with life-threatening blood diseases. They are waiting on blood stem cell transplantations from unrelated donors.

Between 800 and 1 000 children in South Africa are diagnosed with cancer annually.

However, this number does not account for the almost 50% of cases of childhood cancer that are never diagnosed, due to a lack of knowledge regarding the disease and how it presents in children.

Because children still experience growth spurts within a short space of time, this may cause blood cancer and disorders to spread quicker and more aggressively. Therefore, diseases affecting young children are those most often occurring in the developing cells, such as bone marrow, blood, kidneys and nervous system tissues.

Rayaan, Emily and Neos families lives have been turned upside down by blood cancer and disorders.

Rayaan was diagnosed with life-threatening acute myeloid leukaemia when he was just eight weeks old. AML usually requires immediate treatment and for Rayaan, bone marrow or blood stem cell transplant is his only chance of a cure.

Without a successful transplant, Rayaan will have to endure continued chemotherapy and isolation, which will expose him to the terminal effects of infection. Rayaan is now in search of an unrelated matching donor, but the low representation of diverse stem cell donors across the country and in the global registry hampers the chances of saving this courageous baby.

Arlene said watching her son endure this pain is heartbreaking and there have been some very dark days. At one point, he had to be resuscitated after a spinal lumbar puncture, but their courageous little fighter battled on and still wakes up every day with a smile on his face.

Please help my baby to live. He is just too little to suffer like this. Dont delay, you could be his perfect match, Arlene added.

Meanwhile, five-month-old Emily from Johannesburg has been battling a blood disorder following her diagnosis in November at only three months. She was diagnosed with juvenile myelomonocytic leukaemia (JMML) and is undergoing treatment, hoping a stem cell transplant will be performed soon.

As in Rayaans case, Emilys best chance at survival is a blood stem cell transplant. Dr Theo Gerdener, a clinical haematologist at Albert Alberts Stem Cell Transplant Centre and medical director at DKMS Africa, said:

JMML, which is especially prevalent in young children, is a rare cancer of the blood and occurs when white blood cells, known as monocytes and myelocytes, mature abnormally. This cancer can occur spontaneously or, sometimes, is linked to other genetic disorders.

Leukaemia affects white blood cells and bone marrow, and alarmingly, childhood leukaemia accounts for around 25% of all cancer in children. With proper diagnosis and management, including stem cell transplantation, childhood leukaemia can be cured in 85% to 90% of patients.

According to Natalie, Emilys mother, her daughter has already endured multiple blood and platelet transfusions, frequent injections and other medication, lengthy hospital stays, including isolation and ICU admission, as well as surgery to insert a port in her chest for intravenous administration.

Her parents desperately hope to find a stem cell donor match through DKMS global stem cell registry and donor centre to provide them with this one in 100 000 chance.

Were keeping positive and are hoping a match will be found for Emily. We hope she grows up, has a normal childhood and becomes a beautiful, bright young lady, said Natalie.

Neo was diagnosed with Fanconi anaemia in April 2019 at only four years old. A couple of years earlier, his older sister, who was also diagnosed with the same blood disorder, received a stem cell donor transplant, giving her a second chance at life.

Their dad, Phoebus, recalls the late-night rushes to the hospital, overnight stays and time away from work, as both parents grappled with the unusual, but persistent symptoms in their child, as Neo endured uncontrollable nosebleeds, debilitating fatigue, prominent bruising and innumerable fevers and infections owing to his compromised immune system.

Neo is transfusion-dependent and receiving steroid treatment, among other things. He is also searching for his second chance at life through an unrelated donor match to provide him with a life-saving blood stem cell transplant.

A donor with the same ethnic background as a patient may be a better match than one who comes from an entirely different background.

Globally, there are a low number of registered donors among the black, Indian and mixed-ethnic populations, meaning the pool of prospective matches is significantly lower.

For patients like Neo, a substantial increase in the registration of black donors will directly impact his chances of a successful transplant from a matched donor.

Neos family has thrown its support behind DKMS Africa to champion the cause of education and awareness around blood diseases.

People need to be aware of these medical conditions and empower themselves with the knowledge. Some people and organisations are there to help. People should not be afraid to reach out, said Phoebus.

If you are in good health and between the ages of 18 and 55 and considering joining the registry, visit http://www.dkms-africa.org or call 0800 12 10 82, weekdays between 08:30 and 16:30.

Once you have registered online, a swab kit is sent to you via courier and then collected when you have completed the process (at no cost to you). Take action, save a life!

Dr Jackson Orem, the Director of the Cancer Institute, gave a detailed patient history to highlight the cause of the departed former speaker Jacob Oulanyahs death at the State funeral in Kololo, Kampala. last Wednesday.

Eloquent he was in narrating that the patient had utilised the two lines of treatment available in Uganda and was only left with two experimental options including stem cell therapy.

Stem cell therapy involves extraction of bone marrow cells and implanting them in the body to rejuvenate its ability to produce white blood cells. In the case of the former Speaker, the Minister of Health Dr Ruth Aceng highlighted that the patient had lost his spleen decades ago compromising his immunity. She read from the post mortem report the patient suffered from a compound of various bacterial and viral infections and succumbed to multiple organ failure.

In all these, perhaps the only addition would have come from a pathologist to elaborate further and pinpoint the exact cause of death. Pathologists are the academic doctors who study forms of life in its innate forms, whether as tissue, examining dead bodies etc. In some analyses these are supported by microbiologists. All these people exist in close proximity on Mulago Hill and the new national testing center at Butabika. Listening to Dr Orem it is clear Ugandas problem is not the diagnostic part.

The diagnostic part has only failed in delivery to the general population due to its prohibitive cost. For most patients it is the treatment part that drives patients and their families to desperation.

The stories of the on-and off operations of the two cobalt machines in Mulago that administer radiotherapy is well documented. Radiotherapy burns the cancerous cells that are trying to outnumber the white cells that produce antibodies to defend the body from infections.

There are a few things Dr Orem may have inserted in the national conversation. First is the rising number of cancer cases. Last count says 30,000 cases but these are the diagnosed cases processed through the Cancer Institute. All non-communicable diseases are on the rise. Cancer is just behind cardio-vascular diseases. Others are chronic respiratory diseases, type 2 diabetes mellitus (DM), and chronic kidney disease.

A recent study in 2021 in BMC Journal shows that rural areas are seeing as much of an upswing as urban areas where conditions like cancer are associated with lifestyle. Non communicable diseases are a big profit center for big pharma as management costs are high. Its an area where name brands have overwhelmed generic drugs.

The other version of cancer triggers are stress and chemicals in the water supply. The introduction of contraceptives in the 1970s as women entered the workforce is blamed for a surge in a generation of mothers. GMO foods which have made cooking oil a staple in many homes are also a factor.

Processed foods are also a factor, including artificial colouring, hydrogenated fats and saturated oils. Very few Ugandans know that cooking oil can easily run a diesel engine.

During the Covid pandemic, NCD patients suffered more from the ravages of the disease, including debilitating strokes, heart attacks that played on the vulnerabilities NCD sufferers find themselves in.

Managing these diseases is only going to get more complicated as the big anchor in the healthcare supply system USAID is exiting.

The cancer center is already too small, patients waiting for hours in agony for relief. In the Covid interlude, Mulago (when patients dropped between January and April 2021), offered excellent care to in-patients.

This all round model can be replicated for cancer patients. If there is excess capacity at the new womens hospital it could be used. Cancer is a one way street, all the urgency that people are treated with dignity.

Hoth Therapeutics (NASDAQ:HOTH) has gained ~135% in the pre-market Monday after the development-stage pharmaceutical company announced encouraging preclinical data for its investigational cancer therapy, HT-KIT.

KIT is designed to target the receptor tyrosine kinase KIT in mast cells, required for the normal functioning of bone marrow-derived hematopoietic stem cells. The mutations of the KIT pathway are linked to human cancers, such as gastrointestinal stromal tumors and mast cell-derived cancers.

According to the company, a team of researchers, who were part of a scientific research agreement with North Carolina State University, found that KIT protein expression, signaling, and function reduced in response to HT-KIT mRNA frame-shifting approach on mast cell leukemia cells in vitro.

The treatment was found to have prevented cancer cell growth and induced cell death over 72 hours.

Additionally, in a mouse model with mast cell leukemia, the tumor growth and infiltration of other organs reduced, and tumor cell death rose when HT-KIT induced frameshifted c-KIT mRNA, Hoth (HOTH) said.

Our next round of preclinical studies are underway and we are excited to utilize the results for our planned Pre-IND meeting with FDA later this year," Chief Executive Robb Knie said.

HT-KIT was granted the FDAs Orphan Drug designation early this year.

The addition of the E-selectin antagonist uproleselan (GMI-1271) to chemotherapy has been shown to improve outcomes in patients with relapsed/refractory acute myeloid leukemia (AML), according to Tapan M. Kadia, MD, who added that based on these findings, the investigative agent is now under further exploration in several disease subsets and settings with varying unmet need.

The idea is that [uproleselan] may reduce or subvert chemotherapy resistance. This has been shown in several preclinical studies where mice that had been treated with cytarabine and had leukemic blasts left over after [treatment] showed that they had tight binding to E-selectin within the tumor microenvironment, Kadia explained. When uproleselan, or an antibody blocking E-selectin, was added, those cells then became sensitive to the cytarabine, suggesting that the E-selectin binding was leading to chemotherapy resistance. This [supported the hypothesis that] blocking E-selectin within the microenvironment can be an important mechanism to provide benefit in patients with AML.

Data from a phase 1/2 clinical trial (NCT02306291) showed that when uproleselan was administered at the recommended phase 2 dose of 10 mg/kg twice daily in combination with mitoxantrone, etoposide, and cytarabine (MEC), it produced a remission rate of 41% in those with relapsed/refractory disease (n = 47).1 In a cohort of patients with newly diagnosed disease who were at least 60 years of age (n = 25), the combination of uproleselan plus cytarabine and idarubicin (7+3) resulted in a remission rate of 72%.

Now, a phase 3 trial (NCT03616470) is examining MEC or fludarabine, cytarabine, and idarubicin (FAI) with or without uproleselan in patients with relapsed/refractory AML who are eligible for intensive chemotherapy in the salvage setting.2 Another phase 3 trial (NCT03701308) is exploring 7+3 chemotherapy with or without uproleselan in patients aged 60 years or older who are fit for intensive induction chemotherapy.3 Moreover, a phase 1/2 trial (NCT04848974) is evaluating cladribine and low-dose cytarabine in combination with uproleselan in difficult-to-treat patients with treated secondary AML.4

In an interview with OncLive, Kadia, an associateprofessor in the Department of Leukemia, of the Division of Cancer Medicine, at The University of Texas MD Anderson Cancer Center, discussed what makes uproleselan unique from other agents under investigation in AML and shed light on the many research efforts dedicated to further exploring its use in this disease.

Kadia: E-selectin is a relatively new target, but it is a protein that we have known about for many years. E-selectin is present on activated endothelial cells, [which are] the cells that make up a blood vessel. E-selectin is present, upregulated, and overexpressed in activated endothelial cells at the sites of inflammation and damage.

We [believe] E-selectin is meant to help attract or traffic leukocytes and white blood cells, including monocytes, neutrophils, and natural killer [NK] cells, to the sites of inflammation. Neutrophils, NK cells, and monocytes have E-selectin ligands, which are glycoproteins that are attracted to or attached to E-selectin. E-selectin on the endothelial cells helps to traffic these cells and adhere them to the endothelial cells.

More recently, E-selectin has become recognized as a potentially important marker in malignancy, because they are also expressed in endothelial cells associated with malignancy. For example, in solid tumors, there is a suggestion that it may have a role in metastasis or distant metastasis of solid tumors, such as colon cancer.

In leukemia and hematologic malignancies, the endothelial cells in bone marrow also overexpress E-selectin, particularly in advanced disease. They are expressed at higher levels in patients who have adverse-risk AML, patients who have been previously treated, and they allow the adherence of leukemic blasts of the malignant cells to the endothelial microenvironment within the bone marrow.

As [the endothelial cells do that], we believe that the E-selectin binding to these cells upregulates nuclear factor kappa B [NF-B] within the tumor or the blast, and elicits a type of chemotherapy resistance, or prosurvival pathways, that allow them to survive chemotherapy or treatment. Blocking this [from happening] has been the rationale behind [the development of] uproleselan. Blocking this may help prevent the trafficking of the blast cells to the bone marrow and from adhering to the bone marrow microenvironment, therefore inhibiting activation of the cancer survival pathways, such as NF-B.

Uproleselan is an antagonist of E-selectin that binds to E-selectin and prevents the interaction between E-selectin and E-selectin ligands, which are present on leukemia or AML blasts. It is an intravenous product that is given over 20 minutes twice daily.

[During] an initial study, [investigators] observed no significant toxicities [with uproleselan] as a single agent. The mechanism is that it blocks the interaction between the E-selectin and the E-selectin ligands on the blasts, therefore reducing the trafficking of these leukemic blasts to the bone marrow. It disrupts the adhesion-mediated drug resistance within the bone marrow microenvironment.

In that respect, it also inhibits the activation of potential cancer survival mechanisms, such as upregulation of NF-B, and may reduce chemotherapy-based toxicity that may occur. By reducing [E-selectin adhesion] and adding chemotherapy, you are treating cells that are potentially more sensitive to [chemotherapy].

The [hypothesis] was that blocking E-selectin would thereby sensitize the resistant leukemic blasts to chemotherapy, particularly in the salvage setting. You want to start in patients with relapsed/refractory AML.

This was a phase 1 study that looked at the combination of the E-selectin antagonist, uproleselan, with either MEC chemotherapy in patients with relapsed/refractory AML, or in combination with 7+3 chemotherapy in a small cohort of newly diagnosed patients with AML who were aged 60 years and older. Once patients achieved remission, they could also get uproleselan with their consolidation, whether it be MEC consolidation or intermediate-dose cytarabine-based consolidation.

A total of 66 patients with relapsed/refractory AML were treated, with a median age of 59 years of age. Moreover, 17% of those patients had prior transplant, and one-third of the patients had 2 or more induction regimens; [as such, it was] a heavily pretreated population. Fifty percent of patients had adverse-risk [disease] by European LeukemiaNet risk [classification].

If you look at the adverse [effects (AEs)], and this is 1 of the first striking observations, there may have been potentially lower toxicityparticularly along the gastrointestinal tract starting with mucositis, nausea, and vomitingthan what you would expect with MEC chemotherapy based on historical experience. The most common complications were infections, which are common in patients [with leukemia] who are treated with intensive chemotherapy.

When you look at efficacy among the 66 patients who were treated, the complete response [CR]/CR with incomplete count recovery [CRi] rate was [41%], and the early mortality [rate] was fairly low, at 9% at 60 days, which is reasonable. Patients who had a longer CR1 duration had a higher response rate at 75% vs those who had refractory disease or a short CR1 duration, [with] response rates in the range of 23% and 36%.

[Additionally], 69% of patients had minimal residual disease [MRD] negativity, which is good for a relapsed/refractory cohort setting. The efficacy was there, as seen by the overall response rate [ORR] of 39%, which is in line with what you would expect with salvage chemotherapy in the relapsed/refractory setting. The median overall survival [OS] of the patients is [8.8] months, [which is] promising for a study looking at relapsed/refractory AML.

One of the interesting correlative studies looked at E-selectin ligand expression on the blast cells and survival. Looking at baseline AML, a prior study suggested that patients whose blasts had high expression of E-selectin ligand had a more adverse prognosis then those with low expression. Moreover, E-selectin ligand overexpression [is known to] correlate with relapsed/refractory disease and adverse prognosis disease. As such, high E-selectin ligand is associated with a poor prognosis.

[However, in this correlative study,] patients who had high E-selectin ligand expression and were treated with uproleselan had a more favorable outcome, with a median OS of 12.7 months compared with 5.2 months in those who had low [E-selectin ligand] expression. That suggests that in those patients who typically would have a more adverse prognosis with high E-selectin ligand expression, when you added uproleselan, which blocked that interaction, their prognosis improved. That was an early signal that suggested that targeting that receptor flips the adverse prognosis associated with E-selectin ligand expression.

[The phase 1/2] study also had an arm of newly diagnosed patients, who were treated with 7+3 chemotherapy plus [uproleselan]. These were older patients with newly diagnosed AML; [this cohort was comprised of] 25 patients who had a median age of 67 years. Half of patients had secondary AML, which is commonly seen in that population.

Here, the rates of grade 3 or 4 mucositis were 0%, with about 20% [of patients experiencing] grade 1/2 mucositis, so lower rates in mucositis than we may have expected with intensive chemotherapy. The CR/CRi rate was 72% [with this approach], with 52% [of patients] achieving a complete remission. The early mortality [rate] at 60 days was 12%, [which is] higher than you might expect in older patients, but still reasonable and promising. The MRD negativity [rate] was 56% among the patients who were evaluated for it. As such, this was a pretty good response rate that was in line or higher than what you would expect with intensive chemotherapy.

Based on the promising data from the phase 1 trial, looking at patients with relapsed/refractory AML treated with MEC plus uproleselan, as well as the small cohort of frontline patients treated with uproleselan and 7+3, the sponsor decided to proceed with a couple of phase 3 randomized trials to register uproleselan for patients in these particular settings.

The primary end point for both studies is OS, to evaluate the combination of anti-leukemic activity uproleselan with the respective chemotherapy. Secondary end points also include trying to further study and nail down the incidence of severe oral mucositis. Is it less than what you would expect with the control arm?

The first is a randomized phase 3 study [NCT03616470] for patients between the ages of 18 years and 75 years, with relapsed/refractory AML who are eligible for intensive chemotherapy in the salvage setting. They may have had 1 or fewer allogeneic stem cell transplants [ASCTs] prior to enrollment. Patients are randomized [1:1] to either MEC or FAI chemotherapy, plus or minus uproleselan. If patients achieved remission, they could receive consolidation with high-dose [cytarabine] or intermediate-dose [cytarabine], plus or minus uproleselan. The primary end point of the study is OS. The study is in the early stages [and we] hope to see data in the next couple of years.

The second is an National Cancer Institute study [NCT03701308] that is looking at patients aged 60 years or older who are fit for intensive chemotherapy [in the frontline setting]. Patients who have secondary AML [will be included], but those with FLT3-mutated AML [will not], since there is a standard of care for that [in the form of] FLT3 inhibitors.

Here, patients are randomized [1:1] to 7+3 chemotherapy with or without uproleselan, with consolidation with intermediate-dose cytarabine, with or without uproleselan. The primary end point [is] OS, and there will be an interim analysis looking at event-free survival [EFS]. If there is an inferior EFS at the interim [analysis], then the study would be closed at that point for futility. Otherwise, it would continue to look for OS benefit [with this approach]. Hopefully, we will see some data in the next year or 2 [to shed light on whether] this is a good strategy [for these pateints].

The treatment paradigm in AML has shifted significantly over the past few years with the incorporation of new molecules, such as venetoclax [Venclexta], [plus] IDH1, IDH2, and FLT3 inhibitors. Things are changing rapidly, even as uproleselan is being developed.

Now, instead of saying we have patients who are older and fit for chemotherapy, you must ask [questions about mutations]. Does a patient have a FLT3 mutation? If so, maybe they should be treated with a FLT3 inhibitor combined with chemotherapy. Does a patient have an IDH1 or IDH2 mutation? Recent data from the 2021 ASH Annual Meeting suggested that the combination of ivosidenib [Tibsovo] and azacitidine showed a significant survival benefit in patients who are IDH1 mutated compared with azacitidine alone. As such, there is another option for that specific subset of patients.

We have other medications or intensive chemotherapy for patients who have secondary AML. [For example,] CPX-351 showed a significant survival benefit compared with 7+3 chemotherapy. Where does uproleselan fit in secondary AML? Well, if you start with the relapsed/refractory setting, there is no 1 standard of care. As such, if uproleselan does show significant benefit compared with MEC alone in terms of survival, that is one place to go.

[If patients] have FLT3-, IDH1-, or IDH2-mutated, options such as gilteritinib [Xospata] and ivosidenib are available for those respective subtypes. However, in those patients who do not have those mutations, [uproleselan] could be an option.

A [phase 1/2] pilot study [NCT03214562] that is being done by [investigators at The University of MD Anderson Cancer Center] looked at [the combination of] FLAG [fludarabine, cytarabine, granulocyte colonystimulating factor] plus idarubicin and venetoclax [in patients with relapsed/refractory AML] and showed very high rates of complete remission with MRD negativity. This is a very intensive study, that needs close follow-up and close safety evaluation, but certainly, [we are seeing] high response rates with most of the patients able to proceed to ASCT and good survival in the long term. How does uproleselan fit in that setting?

If [the addition of uproleselan] shows a benefit over MEC as a single agent, it is certainly an option. [Now, we must determine] which patients you would put on that particular study, if they have no targetable mutations or if they cannot tolerate intensive chemotherapy plus venetoclax, whether it be FLAG plus idarubicin/venetoclax, or a regimen we developed, [like CPX-351] plus venetoclax.

In the frontline setting, it gets even more difficult because frontline studies are looking at [combining] a hypomethylating agent [HMA] with venetoclax in older patients. This [approach] is currently approved for patients who are aged 75 and older, or those who are unfit for intensive chemotherapy. However, [this approach] may start to be applied to patients who are slightly younger than that or who are more fit than the most unfit patients. [Investigators] are examining HMA plus venetoclax in that older, fit population. New regimens, such as cladribine, low-dose cytarabine, plus venetoclax, have also demonstrated high response rates in that older, fit population.

A set of studies is evaluating [CTX-351 in secondary AML]. For patients with IDH1 mutations, we now have the option of HMA plus ivosidenib. For FLT3-mutated disease, we are still looking, but HMA/venetoclax has high response rates in that setting. Moreover, triplet combinations are also being investigated, where [agents such as] gilteritinib or quizartinib are being added to the backbone of HMA plus venetoclax.

In the frontline, so many different options [are available] for specific subtypes, so we must define where 7+3 plus uproleselan will fit in, if data are positive. This is still a question that will need to be answered.

We are conducting a trial in a specific subset of patients who do not have great options [available to them] right now: those with treated secondary AML. This is a population of patients who may have had myelodysplastic syndrome [MDS] or chronic myelomonocytic leukemia [CMML] prior to developing AML, which is very common in the population. These patients were treated with the standard of care, which is HMAs and 5-azacytidine or decitabine in the frontline for MDS or CMML.

Eventually, these patients may respond [to treatment], but they may then progress to AML. At the time of their progression, they are considered to have newly diagnosed AML, but they may have received months or years of HMAs. This [scenario] used to be [referred to as] HMA failure, but this is a specific subset of AML that arises from previously treated MDS or CMML. In these patients, the complete remission rates are in the range of 20% to 25% with standard agents, and early mortality is very high. These patients have a median OS in the range of 4 to 5 months at the time of diagnosis AML, so it is a difficult subset of patients [to treat] for whom there really is no therapy [available]. If you look at CPX-351 in that setting, which is treated secondary AML, outcomes are pretty much the same, with high rates of early mortality and poor OS.

We wanted to address this key subset of patients. One of the things that we learned from the preclinical studies with uproleselan is that E-selectin is upregulated and overexpressed in AML blasts that have been previously exposed to HMAs. AML or MDS blasts that have been treated with or exposed to HMAs upregulate E-selectin significantly. The rationale was if these patients who have failed or have been treated extensively with HMAs then develop AML, their blasts may have upregulated E-selectin, and they may be the ideal target for uproleselan in combination with chemotherapy.

We took that specific subset of patients, and we are studying the combination of uproleselan plus cladribine and low-dose cytarabine [as part of a phase 1/2 trial (NCT04848974)]. The cladribine and low-dose cytarabine regimen has been developed at MD Anderson and, for many years now, has been used in frontline AML and treated secondary AML. In that specific subset [of treated secondary AML], we have seen a response rate [ranging from] 35% to 40% in the frontline [setting].

Since it is not [additional treatment with a] HMA, this backbone in combination with uproleselan is being studied in patients with treated secondary AML, with the end point of safety, [as well as] secondary end points of remission rate and OS in this difficult population, where there is a [need] that needs to be critically addressed.
