Sellas’ Regal Moves Toward Final Readout

Sellas disclosed last month that Regal had reached its pre-specified 80th event, triggering the final analysis. The next steps include database lock, unblinding and statistical analysis ahead of an expected Q4 readout.

The Phase 3 trial evaluates Galinpepimut-S (GPS) as maintenance treatment for acute myeloid leukemia (AML) patients in second complete remission, with overall survival as its primary endpoint. “Reaching the 80th event represents a critical milestone in the REGAL trial,” CEO Angelos Stergiou said. 

Last week, Stergiou reiterated that Sellas anticipates reporting the primary endpoint data soon.

On a quarter-over-quarter basis, analysts expect no revenue and a loss of $0.05 per share, both unchanged from the previous quarter, according to Koyfin. Operating loss is projected to narrow slightly to $10.42 million from $10.63 million.
