XBiotech Announces Completion of U.S. Enrollment in Phase 2 Multicenter Study Evaluating Bermekimab in Patients with Hidradenitis Suppurativa

AUSTIN, Texas, Sept. 24, 2018 (GLOBE NEWSWIRE) --  XBiotech Inc. (NASDAQ: XBIT) announced today that it had completed enrollment in the U.S. for its Phase 2, open label clinical study evaluating subcutaneous administration of bermekimab in patients with moderate to severe Hidradenitis Suppurativa (HS). Enrollment has exceeded the planned limit for the study in just over two months, significantly outpacing expectations. XBiotech plans to accept a limited number of additional patients in Europe prior to study completion.

John Simard, Chairman & CEO of XBiotech, commented, “We are very pleased by the enrollment rate we have seen in this study. Patient availability has been well beyond what was predicted. I believe this speaks to the need for new treatment options for this debilitating disease. I want to thank all of the patients and clinical sites for their ongoing participation in this study.”

The phase 2 study involves a 13-week treatment regimen. Two groups of patients are being treated with bermekimab: those who have had and failed prior anti-TNF therapy; and those with no prior anti-TNF treatment history. Bermekimab was previously evaluated for treatment of hidradenitis suppurativa in a double blind, placebo controlled study. In that study, 60% of treated patients achieved the primary efficacy endpoint, a positive HiSCR, versus only 10% of patients who had received placebo. Patients were treated with an intravenous formula of bermekimab. Based on feedback from key opinion leaders, XBiotech developed and is now evaluating a subcutaneous formulation in pre-filled syringes that can be conveniently administered.
