A Multi-center, Randomized, Double-blind, Placebo-controlled Phase III Study to Assess the Efficacy and Safety of XW003 Injections in Obese Participants With Obstructive Sleep Apnea Receiving Positive Airway Pressure Therapy
The aim of the study is to assess the efficacy and safety of XW003 injections in obese participants with OSA receiving PAP
Inclusion: Body mass index (BMI) ≥ 28.0 kg/m2; The results of PSG meet the diagnosis criteria of OSA and with an AHI≥15 at screening; Have been on PAP therapy for at least 3 consecutive months prior to screening and plan to continue PAP therapy during the study; Have a history of at least 1 self-reported unsuccessful dietary effort to lose body weight.
Exclusion: Change of body weight >5% within 3 months prior to screening (selfreported); Have a prior or planned surgical treatment for obesity (except liposuction or abdominoplasty if performed more than 1 year prior to screening); History of endocrine disorders which have significant impact on body weight; Diagnosis of diabetes (except gestational diabetes), ketoacidosis or hypertonic state/coma; Respiratory and neuromuscular diseases that could interfere with the results of the trial; Diagnosis of Obesity Hypoventilation Syndrome or daytime hypercapnia; HbA1c ≥6.5% at screening; Fasting blood glucose ≥7.0 mmol/L or 2-hour blood glucose ≥11.1 mmol/L after oral glucose tolerance test (OGTT) at screening; participants with FBG ≥6.1 mmol/L but <7.0 mmol/L require OGTT; Have received any medication for body weight loss and blood glucose lowering or medication that could lead to significant body weight increase, within 3 months prior to screening; Have diagnosis of Cheyne Stokes Respiration, or diagnosis of Central or Mixed Sleep Apnea with % of mixed or central apneas/hypopneas ≥50%.
