Mezzion Pharma Co. Ltd. announced that top line data from the Phase 3 FUEL trial, which was designed to evaluate the safety and efficacy of udenafil for the treatment of certain adolescents with congenital single ventricle heart disease (SVHD), had positive results for key parameters. Although Mezzion is restricted in providing specific data results at the present time due to contractual obligation, the Company is looking forward to publication of the full results in a peer reviewed journal and the presentation of the clinical trial data at a major scientific meeting later this year.
