The company previously said that 72 events had been recorded as of Dec. 26. Once the threshold is reached, Sellas plans to proceed with database lock, statistical analysis and unblinding of the study.<\/p>\n<p>Stergiou has said that slower accumulation of survival events in oncology trials can sometimes indicate patients are living longer than initially expected. He also reiterated recently that his \u201cconviction in the REGAL trial\u2019s prospects and ultimate commercial potential remains as steadfast today as it was day 1.\u201d<\/p>\n<p>Sellas Seeks 20M Share Plan Boost<\/p>\n<p>Separately, Sellas has asked shareholders to approve an expansion of its 2023 Amended and Restated Equity Incentive Plan by\u00a0<a href=\"https:\/\/stocktwits.com\/news-articles\/markets\/equity\/sls-stock-retail-no-vote-20m-share-plan-before-aml-results\/cZQNDC3ReIp\" rel=\"nofollow noopener\" target=\"_blank\">20 million shares<\/a>, aiming to replenish its stock-based compensation pool. The company said only 7,991 shares remained available for future awards as of mid-April. The approval would also allow a previously approved grant of 1.1 million restricted stock units to Stergiou to take effect.<\/p>\n<p>As of April 15, Sellas reported 2.64 million stock options and 2.26 million restricted stock units outstanding, with total equity overhang representing about 2.6% of shares outstanding.<\/p>\n<p>Beyond Regal, the company has pointed to 2026 as a key year for its CDK9 inhibitor SLS009, with clinical updates and topline data expected from ongoing Phase 2 studies. Preclinical findings showed that the therapy triggered programmed cell death in leukemia cells and remained active in AML associated with ASXL1 and TP53 mutations.<\/p>\n<p>How Do Retail Traders Feel About SLS?<\/p>\n<p>On Stocktwits, retail sentiment for SLS was \u2018neutral\u2019 amid over a 200% jump in 24-hour message volumes.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.europesays.com\/europe\/wp-content\/uploads\/2026\/05\/sls_ss_png_8a78d55d93.webp\" alt=\"sls ss.png\" width=\"974\" height=\"140\"\/>SLS sentiment and message volume as of May 4 | Source: Stocktwits<\/p>\n<p>One user\u00a0<a href=\"https:\/\/stocktwits.com\/G_Trade\/message\/652199176\" rel=\"nofollow noopener\" target=\"_blank\">noted<\/a> Stergiou\u2019s LinkedIn post and said, \u201cThat is the footprint of a company stepping onto a much bigger stage.
