Just days before it’s set to share new data for its lead candidate, Alumis raised $259 million in a series C that will bring that same programme into pivotal trials.
The company is presenting Phase II data at the upcoming American Academy of Dermatology (AAD) annual meeting for its oral TYK2 inhibitorTYK2 inhibitor ESK-001 to treat moderate-to-severe plaque psoriasis.
The upsized financing, which was co-led by existing investor Foresite Capital and new investors Samsara BioCapital and venBio Partners, will help Alumis launch Phase III studies of ESK-001 next half.
The round also saw participation from new investors Cormorant Asset Management, SR One, Lilly Asia Ventures, Nextech, Ally Bridge Group, HBM Healthcare Investments, Omega Funds, Piper Heartland Healthcare and existing investors AyurMaya, an affiliate of Matrix Capital Management and a US-based healthcare-focused fund.
Best-in-class selectivity?
Alumis thinks ESK-001 could be best-in-class in the increasingly competitive TYK2-autoimmune space. For more on the psoriasis landscape, see KOL Views Q&A: Leading dermatologist lays out decision tree for psoriasis treatments.
The next TYK2 blocker most likely to hit the market is Takeda’s TAK-279, which is in a Phase III trial to treat moderate-to-severe plaque psoriasis.
According to Alumis, ESK-001 is designed to be more selective for TYK2 than Sotyktu or other therapies in the clinic. The compound showed no pharmacological inhibition of JAK1/2/3 in Phase I testing, with no observed JAK-related safety events to-date.
Wednesday’s financing will also support two separate, ongoing Phase II trials of ESK-001: the LUMUS study in systemic lupus erythematosus, and the OPTYK-1 proof-of-concept trial in non-infectious uveitis.
Alumis’ TYK2 inhibitorTYK2 inhibitor portfolio also includes A-005, a central nervous system-penetrating compound in preclinical development for neuro-inflammatory diseases such as multiple sclerosis (MS).
