SAN FRANCISCO and BOSTON, Jan. 09, 2026 (GLOBE NEWSWIRE) -- MapLight Therapeutics, Inc. (MapLight) (Nasdaq: MPLT) today announced an update to the expected timing of topline results for its ongoing Phase 2 ZEPHYR and IRIS clinical studies, which are progressing ahead of schedule.
The company’s Phase 2 ZEPHYR trial evaluating ML-007C-MA for the treatment of schizophrenia continues to enroll robustly, and topline results are now expected in the third quarter of 2026. The ZEPHYR study is a randomized, double-blind, placebo-controlled trial that is expected to enroll 300 hospitalized adult participants with schizophrenia experiencing acute exacerbation of psychosis.
“The accelerated enrollment pace in the ZEPHYR trial allows us to narrow our timing guidance to the third quarter of 2026,” said Chris Kroeger, co-Founder and Chief Executive Officer of MapLight. “This momentum is testimony to our disciplined execution and commitment to advancing our programs efficiently while maintaining the highest quality standards.”
In addition, following completion of enrollment in the Phase 2 IRIS trial for ML-004 in autism spectrum disorder, topline results for that study are now expected in the third quarter of 2026. The IRIS study is a double-blind, placebo-controlled trial that randomized approximately 160 adult and adolescent participants.
