Sellas Life Sciences shares rose after the company said its Phase 3 trial is nearly ready for data review.
The stock gained 13% to $5.91 in after-hours trading. Through the close, the stock was up 38% year to date.
The late-stage clinical biopharmaceutical company's Phase 3 trial evaluating Galinpepimut-S as a treatment for leukemia requires 80 pre-specified events to lock the database and start analyzing it.
As of May 11, 78 events had occurred, Sellas said. The company plans to provide an update when the 80th event happens.
Sellas also said its loss widened to $8.4 million, or 5 cents a share, compared with a loss of $5.8 million, or 7 cents a share, in the year-ago quarter.
