XBiotech will continue its True Human anti IL-1⍺ antibody discovery program outside of dermatology and use its manufacturing technology to produce clinical supplies of bermekimab for Janssen
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.

XBiotech plans to use a portion of the proceeds from this transaction to fund discovery and development of its next generation True Human anti-IL-1⍺ antibody program. Additionally, a portion of the revenue will be dedicated to advancing other antibody therapeutics in XBiotech’s pipeline. The Company is also planning to use part of the proceeds in a capital transaction, such as a stock repurchase, subject to board review and approval.
John Simard, XBiotech’s President & CEO, stated, “We are proud that Janssen has chosen bermekimab as an agent it believes could have an important impact. We believe their acquisition will enable recognition and increase awareness of the full potential of this first-in-class therapeutic. This transaction also provides us the opportunity to showcase our powerful True Human antibody discovery platform, which we are now utilizing to pursue next generation anti-Il-1⍺ antibody therapeutics to treat multiple areas of unmet need outside of dermatology.”
The acquisition of bermekimab provides further validation of the foundational science behind targeting IL-1a as a means to block disease-causing inflammation. Clinical and pre-clinical research suggests blocking IL-1a may be used to treat a number of chronic and acute inflammatory conditions, including skin disease, heart disease, heart attack, stroke, rheumatological disease, gastrointestinal diseases, and cancer.
Simard further stated, “The cash infusion from the bermekimab transaction will enable XBiotech to accelerate our True Human antibody pipeline. The Company will also have sufficient cash to support a significant capital transaction, which could provide for a non-dilutive liquidity event for our valued shareholders who have supported XBiotech’s pioneering work.”
The transaction is subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act, and is expected to close shortly after HSR approval.
