Bermekimab[1] (MABp1, trade nameXilonix) is a humanmonoclonal antibody ofIgG1kisotype targeting Interleukin 1 alpha (IL1A).[2]
Bermekimab was developed byXBiotech Inc.[3]
After Phase III trials in Poland failed to show significant improvement in either lean body mass or quality of life, theEuropean Medicines Agency (EMA) rejected the drug application[4].
The companyJanssen Pharmaceutical acquired the license for the drug from XBiotech[5] for the treatment ofatopic dermatitis andhidradenitis suppurativa for $750 million.
As of June 2021[update], bermekimab was also terminated in phase IIIclinical trials as animmunotherapy for advancedcolorectal cancer[6]. The original aim was to treat the debilitating symptoms seen in patients with advanced colorectal cancer, such asmuscle wasting. The study was terminated as it had crossed the prospective futility boundary of primary endpoint.
As of March 2021[update] an additional phase II clinical trial for the treatment ofatopic dermatitis was completed[7]. Janessen andJohnson & Johnson announced was ending development of bermekimab in eczema but said it will continue to work on the previously rejected XBiotech drug in hidradenitis suppurativa (HS). The move resulted in a $610 million pretax impairment charge[8].
