Phase 3
Active, not recruiting
Conditions
Obstructive Sleep Apnea
Overweight
Obesity
Type 2 Diabetes
Interventions
Drug: Placebo
Registration Number
NCT05929079
Lead Sponsor
Eli Lilly and Company
Brief Summary

The purpose of this study is to is to evaluate the efficacy and safety of retatrutide in participants with type 2 diabetes in participants who have obesity or overweight (J1I-MC-GZBK master protocol) including a subset of participants who have obstructive sleep apnea (OSA) (J1I-MC-GSA2). The study will last about 89 weeks and will include up to 24 visits.

GSA2 Exclusion Criteria

  • Use stimulants (for example, modafinil, armodafinil, solriamfetol, pitolisant, amphetamine) less than 3 months prior to screening.
  • Use hypnotics, mirtazapine, opioids, trazodone, and zonisamide less than 3 months prior to screening.

Percentage of Participants with ≥50% AHI Reduction from Baseline for GSA2 SubsetBaseline to Week 80
Change from Baseline in Waist CircumferenceBaseline, Week 80

A Hierarchical Combination of Functional Outcomes of Sleep Questionnaire (FOSQ) 10 score, FOSQ Vigilance Domain Score, and FOSQ Activity Level Domain Score for GSA2 SubsetBaseline to Week 80

A hierarchical combination of change from baseline in the FOSQ 10 score, FOSQ Vigilance Domain Score, and FOSQ Activity Level Domain Score will be assessed by the win ratio. The reported unit will be the total "wins" for each treatment group from performing a hierarchical comparison of the component.
