SELLAS Life Sciences Group Inc
SELLAS ( $SLS ): March 19 2026 . No longer just a one-shot REGAL trade, but still a high-risk biotech story that has to earn its rerating
SELLAS enters 2026 in a stronger position than it did only a few months ago. The company now has a better-funded balance sheet, a pivotal Phase 3 program that remains the center of gravity for the story, and a second clinical asset that is beginning to matter in a more serious way. That does not make the risk disappear. It simply means the equity story is richer, more credible and more demanding than before.

The current story is driven by the cancer vaccine galinpepimut‑S (GPS), a Wilms Tumor 1 (WT1)–targeting immunotherapy, and by a CDK9 inhibitor program for hematologic and solid tumors.

News of the day (REGAL): On 29 December 2025, SELLAS reported that the contract research organization running the Phase 3 REGAL trial notified the company that 72 of the 80 required events (deaths) had occurred as of 26 December 2025. REGAL is an overall survival study; the final analysis will be triggered once 80 events are reached. SELLAS remains fully blinded, and this one-time update does not change the statistical plan.
