Article Summary

SELL
  • Sellas Life Sciences (NASDAQ: SLSL) fell 13% in June as an institutional investor trimmed more than 30% of its stake and SELLAS Life Sciences Group entered a quiet period ahead of key acute myeloid leukemia (AML) readout, with the stock down 13% year-to-date as Regal, its Phase 3 trial evaluating Galinpepimut-S as a maintenance therapy for AML patients in second complete remission, approaches the 80th event required to trigger final analysis after previously reaching 78.
  • The institutional stake cut comes as Sellas CEO Angelos Stergiou warned investors not to treat slower event accumulation as proof of better survival as the company remains blinded.
  • The company has stopped providing trial-specific updates and is focusing on preparations for database lock, regulatory work for a potential biologics license application, and continued development of SLS009, its second AML candidate.
  • Regal would meet its objective if GPS delivers median overall survival of 12.
