XBiotech Announces Enrollment Completion in Phase 2 Multicenter Study Evaluating Bermekimab in Patients with Atopic Dermatitis

AUSTIN, Texas, Oct. 05, 2018 (GLOBE NEWSWIRE) -- XBiotech Inc. (NASDAQ: XBIT) announced today that it has completed enrollment in its Phase 2, open label clinical study evaluating subcutaneous administration of bermekimab in patients with moderate to severe Atopic Dermatitis (AD). XBiotech has now completed and exceeded enrollment in the final cohort of patients who are receiving 400mg weekly doses of bermekimab over an 8 week treatment period. Enrollment for the study is now closed.

XBiotech recently announced it completed the first cohort of patients in the study who received a low dose of bermekimab (200mg/weekly) over a 4 week treatment regimen. The Company reported that patients in the first cohort had significant improvement in multiple efficacy endpoints and that the treatment was well-tolerated.

XBiotech’s Medical Director, Mark Williams, M.D., M.B.A., commented, “I am extremely encouraged by an enrollment rate that has exceeded expectations. We look forward to completing the treatment protocol for our patients and evaluating the results.”

The phase 2, open label, dose escalation, multicenter study consists of two dose cohorts of bermekimab in patients with moderate to severe AD. Dose ranging in the study includes evaluation of the Company’s new highly-concentrated subcutaneous formulation. Nine patients in the first dosing cohort received a total of 4 weekly 200mg subcutaneous injections of bermekimab followed by safety assessments. Patients in the second cohort will receive 8 weekly 400mg subcutaneous injections of bermekimab for assessment of safety and preliminary efficacy.
