What this transaction means for investors
Alumis’ stock has risen over 400% over the past three months, and it appears that Akkaraju expects it to climb higher. There are millions of reasons to sell a stock, but expectations of price appreciation are about the only reason for an insider to add $10 million worth of shares to an already large position. Akkaraju reported to the SEC that he held 6,345,219 shares indirectly through a pair of limited partnerships, the Samsara Opportunity Fund and the Samsara BioCapital fund.
Earlier this month, Alumis reported successful results from a pair of phase 3 trials with envudeucitinib, a next-generation oral therapy candidate for the treatment of psoriasis. About 65% of patients randomized to receive the tablet achieved a 90% of better improvement in their psoriasis area and severity index (PASI) scores. An impressive 40% of patients achieved a 100% improvement after taking the tablet for 24 weeks.
Oral psoriasis treatment, Otezla, from Amgen (AMGN +0.11%) racked up an annualized $2.3 billion in sales during the third quarter of 2025. Alumis’ candidate appears more effective than Otezla. In a phase 3 study leading to Otezla’s approval for psoriasis, 33% of patients who received it achieved a 75% improvement on their PASI scores.
