SELLAS Life Sciences Group Inc's stock rose by 16.90%, reaching a new 52-week high of $3.35 amid positive market conditions, with the Nasdaq-100 up 0.89% and the S&P 500 up 0.79%.
The surge is attributed to the company's recent updates from its pivotal REGAL trial, which showed extended survival for acute myeloid leukemia patients. As of December 26, 2025, the trial reported 72 events, just 8 events short of the 80 needed for final analysis. The Independent Data Monitoring Committee's recommendation to continue the trial without modifications has bolstered investor confidence, leading to a significant increase in stock price.
This positive momentum reflects growing optimism among investors regarding SELLAS's clinical progress and the potential impact of the REGAL trial results on patient outcomes, which could further enhance the company's market position.

Reason
Maxim raised the firm's price target on Sellas Life Sciences to $7 from $4 and keeps a Buy rating on the shares. Shares have risen about 90% year-to-date as the company continues to execute across its Acute Myeloid Leukemia, or AML, programs, the analyst tells investors in a research note. Maxim further cites the company's galinpepimut-S in Phase 3 and yesterday's positive SLS009 data hitting all its endpoints, adding that its higher price target factors in SLS009 in first-line AML as a potential triplet combination with venetoclax/azacitidine.
