XBiotech Announces Presentation of Phase 2 Study Data Evaluating MABp1 for the Treatment of Hidradenitis Suppurativa


Posted on: 07 Sep 17

AUSTIN, Texas, Sept. 07, 2017 (GLOBE NEWSWIRE) -- XBiotech Inc. (NASDAQ:XBIT) announced today that results from the investigator sponsored randomized Phase 2 study evaluating XBiotech’s True Human™ antibody, MABp1, as a treatment for Hidradenitis Suppurativa (HS) will be presented at the European Academy of Dermatology and Venereology (EADV) Congress in Geneva Switzerland. The oral presentation titled, “MABp1, a monoclonal antibody targeting interleukin 1 alpha in patients with hidradenitis suppurativa not eligible for adalimumab: results of a phase II randomized clinical trial” will be given by Theodora Kanni, M.D., Ph.D., Attikon University Hospital in Athens Greece, on 14 September 2017 at  approximately 2pm local time.

Prof. Evangelos Giamarellos-Bourboulis, M.D., Ph.D., who supervises the Outpatients Department for HS of the 4th Department of Medicine at Attikon University Hospital in Greece where the study was conducted and also served as the Principal Investigator of the study, commented, “Hidradenitis is a chronic inflammatory disease with devastating morbidity. It is far too common in our clinic and we do not yet have adequate treatments available. We are truly excited about the results of this clinical study and the potential for MABp1 as a therapy. We look forward to sharing this data with the medical community.”

XBiotech announced topline results earlier this year, reporting that the study met its primary endpoint and demonstrated a significant improvement in HS patients treated with MABp1 compared to control after 12 weeks of therapy (Response rate of 60% vs 10%, respectively (p=0.035)). The 20 patient double-blind, placebo-controlled study was designed to evaluate the safety and efficacy of MABp1, the Company’s True Human antibody targeting interleukin-1 alpha (IL-1α), in patients with HS not eligible for anti-TNF therapy. Patients were randomized 1:1 to receive either MABp1 or placebo every 2 weeks for 12 weeks. Patients in the study underwent primary assessment of efficacy using Hidradenitis Suppurativa Clinical Response (HiSCR) scores at 12 weeks, continued by a follow up phase to assess time to relapse after an additional 12 weeks without therapy. Efficacy measures include assessment of HiSCR scores, a validated method for evaluating efficacy in HS patients, as well as quality of life assessment and ultrasonographic evaluation. Results of the Phase 2 study are planned for publication later this year. 

About Hidradenitis Suppurativa
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 1,2. Therefore, HS is often devastating for patients with significant impact on quality of life 3. The Dermatology Quality Life Index (DQLI) for HS is 8.9, being higher than any other skin disorder 4. Traditional treatments comprise of antibiotics, antiandrogens and surgery. Prevalence rates for HS have been estimated at up to 4%2.
