Regado Slumps on Permanent Termination of Revolixys Study

Zacks

Regado Biosciences, Inc. (RGDO) announced that it is permanently terminating the enrollment process for its phase III REGULATE-PCI study on Revolixys Kit. Regado’s shares tumbled over 60% on the news.

Regado was evaluating Revolixys Kit in patients with acute coronary syndrome undergoing percutaneous coronary intervention (PCI). The study was comparing the safety and efficacy of Revolixys Kit against The Medicines Company’s (MDCO) Angiomax (bivalirudin). The company’s decision to permanently stop enrollment for the phase III study comes after the Data Safety Monitoring Board (DSMB)’s analysis of data from the first 3250 patients enrolled in the study.

Regado stated that the DSMB has found some serious allergic adverse events related to Revolixys. The board also recommended the termination of enrollment in this late-stage study.

In Jul 2014, Regado announced that the DSMB started an unplanned review of data from the phase III REGULATE-PCI study with a focus on serious unfavorable events related to allergic reactions in the patients. Soon after Regado voluntarily stopped patient enrollment for the study. Later in the month, the FDA placed a clinical hold on patient enrollment and dosing in the REGULATE-PCI study (read more: Regado's REGULATE-PCI Study Under Clinical Hold).

Regado now intends to review the database from the REGULATE-PCI study. The company expects the complete review process to take several months.

Our Take

The news of the permanent termination of enrollment for the late-stage study on Revolixys Kit, the company’s lead candidate, is a huge disappointment as the company lacks a decent pipeline. Consequently we believe that the news has dealt the company’s growth prospects a big blow. We expect investor focus to remain on the measures taken by Regado to come out of this setback.

Regado currently carries a Zacks Rank #3 (Hold). Some better-ranked stocks in the health care space include Gilead Sciences Inc. (GILD) and Amgen Inc. (AMGN). Both the stocks sport a Zacks Rank #1 (Strong Buy).
