(SUPN) following the company’s disappointing announcement regarding the failure of its Phase 2b study for SPN-820, a potential treatment for treatment-resistant depression. The study, which was conducted in collaboration with the National Institute of Mental Health, did not meet its primary endpoint, as no significant improvement was observed when compared to a placebo.
Background on the Clinical Trial
Supernus Pharmaceuticals, Inc. had high hopes for SPN-820, which is a novel, investigational, oral kappa opioid receptor antagonist. The drug was being developed to address the significant unmet need in the treatment of treatment-resistant depression, a condition affecting millions of people worldwide.
