TiGenix announces positiveone-year results forits phase I/II trial of donor-derived cardiac stem cell therapy in acute myocardial infarction (AMI).

The Belgian biotech TiGenixis developing allogeneic stem cell therapies. Now the companyhasannouncedthat its cardiac stem cell therapyAlloCSC-01 reached its primary endpoints in aphase I/IItrial.

In 2015, the companyacquired Coretherapixin a292M deal for its allogeneic cardiac stem cell pipeline, which is being developed for the treatment of AMI.The first-in-human trial was designed to test the safety and feasibility of an intracoronary infusion of donor-derivedexpanded cardiac stem cells (AlloCSCs)in patients with AMI and left ventricular dysfunction.

AlloCSC-01consists of adult allogeneic cardiac stem cells isolated from the heartof donors and expanded in vitro. In vivo studies suggest that these cellshave cardio-reparative potential by activating regenerative pathways and promoting the formation of new hearttissue.

Thecurrent phase II study demonstrated thesafety of these allogeneic stem cells. Initial results also revealed a larger reduction of infarct size in a subgroup of patients.

Myocardial infarction caused by blockade of coronary arteries

TiGenix is well known forChondroCellect, which was the first cell therapyto reach the European market for the repair of knee cartilage.After the companyrecently withdrew its market authorization for this product, due to a lack of reimbursement, the biotech is focusing on another stem cell therapy, Cx601, in addition to AlloCSC-01. Under development for Crohns disease, Cx601 is currently awaitingEMA approval and is in phase III trials in the US.

For a late-stage clinical company, TiGenix has a low market cap of191M. Even so, the company seems to be doing well these days with the progress of Cx601 and AlloCSC-01.

If AlloCSC-01 obtains market approval, it could treat the more than 1.9 millionpeople affected by AMI, a major cause of heart failure. So far, most treatments are palliative or restore myocardial function by angioplasty and insertion of a stent to support the vascular lumen.

Stem cell therapy of the heart is definitely not a new topic, but many trials have been conducted using the patients own stem cells derived from the bone marrow. A recent meta-analysisof such trials has suggested that these therapies are safe, but do not enhance cardiac function. TiGenixs approach using allogeneic heart-derived stem cells may offer a new and promisingopportunity in thefield.
