AbbVie Launches Strategic Collaboration with HotSpot Therapeutics to Further Expand Immunology Pipeline
Collaboration leverages HotSpot’s Smart Allostery™ drug discovery platform for the development of the first and only small molecule IRF5 (interferon regulatory factor 5) inhibitor for the potential treatment of autoimmune diseases
HotSpot to receive an upfront cash payment of

NORTH CHICAGO, Ill.
Dec. 6, 2022
/PRNewswire/ — AbbVie (NYSE: ABBV) and HotSpot Therapeutics, Inc., a biotechnology company pioneering the discovery and development of small molecule allosteric therapies for the treatment of cancer and autoimmune diseases, today announced an exclusive worldwide collaboration and option to license agreement for HotSpot’s discovery-stage IRF5 program for the treatment of autoimmune diseases.
“This collaboration with HotSpot has the potential to deliver an entirely new target class of modulators to patients with serious autoimmune diseases, such as systemic lupus erythematosus, and will help to further strengthen our robust immunology pipeline,” said
, Ph.D., vice president and global head of discovery research, AbbVie. “HotSpot’s drug discovery platform has been able to identify molecules that bind to IRF5 in a predictable, reproducible manner potentially enabling effective drugging of what has been considered an undruggable target.”
IRF5 is a transcription factor that acts as a key regulator of certain types of immune responses, and its dysregulation is strongly implicated in several poorly treated autoimmune disorders. Efforts to modulate IRF5 using conventional small molecule approaches have been unsuccessful because IRF5 lacks a traditional active site. Leveraging its proprietary Smart Allostery™ platform, HotSpot discovered what it believes to be the first and only disclosed small molecule IRF5 inhibitor that targets a previously unknown allosteric pocket on the protein that is critical for its endogenous regulation – a “natural hotspot”.
“Today’s agreement with AbbVie underscores our significant progress in rapidly building a substantial pipeline of novel allosteric small molecule therapeutic candidates for the treatment of autoimmune diseases and cancer,” said
, Co-Founder and Chief Executive Officer of HotSpot Therapeutics. “We look forward to collaborating with AbbVie, an industry leader in developing and commercializing important immunology therapeutics.”
Under the terms of the agreement, HotSpot will receive an upfront cash payment of
and may be eligible to receive up to
in option fees and research and development milestones, with potential for further commercial milestones as well as tiered royalties on global net sales. Should AbbVie exercise its option to license, AbbVie will conduct all future clinical development, manufacturing and commercialization activities for the IRF5 inhibitor program. In addition, HotSpot would have a one-time option to share in global R&D costs in exchange for increased royalty payments. Aquilo Partners, L.P. acted as financial advisor to HotSpot on this transaction.
