XBiotech Announces Plan to Launch Randomized Phase 2b Study of Bermekimab in Hidradenitis Suppurativa

AUSTIN, Texas, May 23, 2019 (GLOBE NEWSWIRE) -- XBiotech (NASDAQ: XBIT) announced plans to advance its dermatology program for its true human antibody bermekimab with the launch of a randomized, double-blind, placebo controlled, Phase 2b clinical study in patients with moderate to severe Hidradenitis Suppurativa (HS). This Phase 2b study will evaluate safety and efficacy of bermekimab at different subcutaneous doses compared with placebo. The study will further evaluate efficacy of bermekimab in HS and guide dosing strategies for the anticipated Phase 3 registration study. The Company expects the first patient to be enrolled during the third quarter of 2019.

The Phase 2b study follows two previous successful clinical studies of bermekimab to treat HS.  XBiotech recently evaluated bermekimab in a phase 2 study involving two groups of patients with HS: those who had no prior treatment with biologics; and those who had failed the only approved biological therapy to treat HS. The study, which was conducted at eleven research centers across the U.S. showed bermekimab was similarly effective in HS patients regardless of prior treatment with the current approved therapy.

Results of the study demonstrated that weekly treatment with bermekimab was associated with statistically significant improvement in HS, as measured by the FDA-sanctioned Hidradenitis Suppurativa Clinical Response score (HiSCR). In the study, 61% of patients with no prior biological therapy achieved positive HiSCR at 12 weeks, while 63% of patients who had failed previous biological therapy also achieved a positive HiSCR. HS is associated with severe pain and thus pain was a key measure in the study. At the study’s endpoint, patients with no prior biological therapy had a 64% reduction in pain compared with baseline, while those who had previously failed anti-TNF therapy had a 54% reduction in pain (for the only approved therapy for HS (Humira), only 43% of patients achieved HiSCR in its Phase III study that did not allow antibiotics; and there was no significant reduction in pain for Humira treated patients in the Phase 3 study).

XBiotech’s President & CEO, John Simard, commented, “We are extremely excited about the potential of bermekimab to treat inflammatory skin disease. We are eager to advance this program in HS and to ultimately deliver a new treatment to patients suffering from this devastating disease.”

Hidradenitis Suppurativa (HS) is a chronic, inflammatory skin disorder affecting areas rich in apocrine glands. Nodules appear in the affected areas and progressively become swollen with spontaneous rupture and release of pus. This process occurs repeatedly leading to formation of deep sinus tracts and painful dermal abscesses. Pain is a paramount condition in patients suffering from HS, as this chronic inflammation and accompanying pain account for the fact that HS is ranked first among skin disorders in terms of adversely affecting quality of life. The global prevalence of HS is estimated at up to 4% of the population.
