Notes: Dec. 07, 2019 -- XBiotech Inc. (NASDAQ: XBIT) announced today that it has entered into a definitive agreement with Janssen Biotech, Inc., a Janssen Pharmaceutical Company of Johnson & Johnson, to sell XBiotech’s novel antibody (bermekimab) that neutralizes interleukin-1 alpha (IL-1⍺). IL-1⍺ promotes disease-causing inflammation in a wide range of medical conditions. Janssen will acquire all rights to bermekimab under the terms of the agreement, and XBiotech will be free to use its True Human Antibody discovery program to develop new antibody therapeutics that target IL-1⍺ to treat non-dermatological diseases. XBiotech plans to re-enter clinical development expeditiously with a next generation anti-IL-1⍺ therapeutic. Following the acquisition, XBiotech will use its proprietary manufacturing technology to produce clinical supplies of bermekimab for Janssen under a supply agreement. In addition, XBiotech will contract with Janssen to provide clinical trial operation services to complete two ongoing Phase II clinical studies evaluating bermekimab in Hidradenitis Suppurativa and Atopic Dermatitis. Upon closing, Janssen will make a cash payment of $750 million to XBiotech. In addition, XBiotech may receive up to $600 million in potential milestone payments. XBiotech expects to generate additional revenue from the manufacturing supply agreement and clinical services agreement with Janssen over the next two years.
