DUBLIN, April 20, 2026 (GLOBE NEWSWIRE) -- GH Research PLC (Nasdaq: GHRS), a clinical-stage biopharmaceutical company dedicated to transforming the lives of patients by developing a practice-changing treatment in depression, today issued a statement welcoming the White House Executive Order, signed on April 18, 2026, to accelerate medical treatments for serious mental illness, including innovative psychedelic medical treatments (the Executive Order). The Executive Order directs coordinated federal action to accelerate the development of, and expand patient access to, innovative therapies for serious mental illness. GH Research continues to advance GH001, its proprietary inhaled mebufotenin product candidate, toward initiation of a global pivotal Phase 3 program in treatment-resistant depression (TRD) in 2026.

“We commend the Administration for recognizing the magnitude of the mental health crisis and the urgent need for innovative, evidence-based therapies for patients with serious mental illness. The Executive Order’s emphasis on scientific rigor and cross-agency coordination is well aligned with the approach required to deliver practice-changing treatments, and we remain focused on advancing GH001 toward a global pivotal Phase 3 program,” said Dr. Velichka Valcheva, Chief Executive Officer of GH Research.

About GH Research PLC

GH Research PLC is a clinical-stage biopharmaceutical company dedicated to transforming the lives of patients by developing a practice-changing treatment in depression. GH Research PLC’s initial focus is on developing its novel and proprietary mebufotenin therapies for the treatment of patients with TRD.

About GH001

Our lead product candidate, GH001, is formulated for mebufotenin administration via a proprietary inhalation approach. Based on the observed clinical activity in our Phase 2b GH001-TRD-201 trial, where the primary endpoint was met with a MADRS reduction from baseline of -15.5 points compared with placebo on Day 8 (p<0.0001), we believe that GH001 has the potential to change the way TRD is treated today.
