On the heels of a $259-million March megaround, inflammation-focused Alumis is now gunning to pivot its private success – having garnered more than $600 million in total funding – in the public markets. The biotech joined the IPO queue on Monday and also shared updated timelines for its two clinical candidates, which are in development for several autoimmune and neurodegenerative diseases.
In March, Alumis shared 12-week, Phase II data for the experimental treatment at the American Academy of Dermatology (AAD) annual meeting showing that, among moderate-to-severe plaque psoriasis patients treated with 40mg of ESK-001 twice-daily, 64.1% achieved PASI-75, 38.5% achieved PASI-90, and 15.4% achieved PASI-100.
The benefit improved further over time, as an ongoing label-extension study demonstrated. At 16 weeks, 90% of patients reached PASI-75, 57% saw PASI-90, and 35% achieved PASI-100, comparing favourably to the Phase III data on Sotyktu’s label.
Alumis plans to start a Phase III trial next half of ESK-001 in patients with moderate-to-severe plaque psoriasis.
Alumis’ portfolio also includes A-005, a brain-penetrant compound in development for neuro-inflammatory diseases such as multiple sclerosis (MS). Data from a Phase I trial in healthy volunteers are due by year-end.
According to Alumis, genetic data have shown that “naturally occurring TYK2 loss-of-function genetic variant has a protective effect in MS." The company said it has also demonstrated that protective effect in in vivo models of neuroinflammation.
