Read MoreHide Full Article

Protagonist Therapeutics, Inc. (PTGX - Free Report) announced that it has discontinued phase IIb study – PROPEL – on its ulcerative colitis ("UC") candidate, PTG-100.

Protagonist is a small biotech company focused on developing treatment for inflammatory bowel diseases, Crohn's disease and thalassemia. PTG-100 was the most advanced candidate in the company’s pipeline.

Shares of the company fell 57.2% following the news. In fact, Protagonist’s shares are down 57.9% so far this year, underperforming the industry’s decline of 5.9% in that period.

The discontinuation decision was based on a planned interim analysis of PROPEL study by an independent Data Monitoring Committee. The committee deemed that the study will not be able to achieve its primary endpoint of clinical remission. The interim analysis was done on data from first 65 patients who had completed the 12-week treatment with PTG-100. The total patient population of the study was 240.

However, the company is conducting an extensive review of the data from the study. It has notified that it will stop further treatment of patients currently in the study.

Protagonist has also postponed its decision to initiate a phase II/III on PTG-100 in patients with chronic pouchitis, as it awaits full review of the interim data from the PROPEL study.

Apart from PTG-100, the company is developing two candidates – PTG-200 and PTG-300 – in two separate phase I studies for the treatment of Crohn's disease and beta-thalassemia, respectively.

The company has a worldwide license and collaboration agreement with Johnson & Johnson (JNJ - Free Report) for the development of PTG-200. Moreover, PTG-300 enjoys orphan drug designation in the United States.
