- Original description
This is a 56-week randomized, double blinded, parallel-controlled study evaluating the efficacy and safety of the HDM1005 in patients with obstructive sleep apnea (OSA) and obesity receiving positive airway pressure (PAP) therapy. Eligible participants will be screened and randomized to the HDM1005 group or the placebo group at a ratio of 1:1 , HDM1005 or placebo will be given once weekly for 52 weeks, following by a safety follow up of 4 weeks. All participants received a lifestyle intervention that involved counselling on diet and physical activity.Read full original descriptionShow less
