Helus Pharma announced a shift in its development strategy for HLP004, moving to a monotherapy approach for adults with generalized anxiety disorder. This update comes alongside progress in the company's Phase 3 APPROACH study, which finalized enrollment of 223 participants earlier this year.

Why it matters

The company is targeting a significant unmet need for new treatment options for those managing generalized anxiety disorder. By adjusting the study design, researchers aim to better evaluate the efficacy of HLP004 as a standalone treatment.

Helus Pharma has completed enrollment of 223 participants for its APPROACH Phase 3 trial. The upcoming Phase 2 HLP004 study will utilize a randomized, double-blind, placebo-controlled design to test 30 mg doses in adults with a minimum Hamilton Anxiety Rating Scale score of 20.

The details
