Summary

This trial evaluates the safety & effectiveness of a new treatment for obesity/overweight, knee OA, & obstructive sleep apnea over 89 weeks with 24 visits.

Who is the study for?
This trial is for adults with obesity or overweight, having a BMI ≥30 kg/m², or ≥27 kg/m² with conditions like hypertension. Participants should have tried and failed to lose weight through dieting, may have knee pain due to osteoarthritis for over 12 weeks, and/or moderate-to-severe obstructive sleep apnea but not on PAP therapy. Exclusions include diabetes patients, those with certain genetic syndromes (MTC or MEN-2), history of pancreatitis, recent significant weight changes (>5kg in 90 days), joint diseases other than OA, prior obesity surgery plans.
What is being tested?
The study tests Retatrutide's effectiveness and safety in reducing body weight over approximately 89 weeks compared to a placebo. It includes participants who also suffer from knee osteoarthritis or obstructive sleep apnea. The trial involves up to 24 visits where the intervention's impact on these conditions will be monitored.
What are the potential side effects?
While specific side effects are not listed here, common concerns when testing new treatments for obesity might include gastrointestinal issues (like nausea or diarrhea), potential thyroid problems given the exclusion criteria related to MTC/MEN-2 syndrome, injection site reactions if applicable, and possibly effects on blood sugar levels.
