View original scientific description
The purpose of the studies is to evaluate the efficacy and safety of eloralintide in participants with moderate-to-severe obstructive sleep apnea and obesity or overweight. YDAO is a master protocol designed to support two independent studies: YSA1 and YSA2. Study YSA1 will include participants who are unable or unwilling to use Positive Airway Pressure (PAP) therapy and study YSA2 will include participants who are on PAP therapy for at least 3 months at time of screening and plan to continue PAP therapy during the study. Participants will be assigned to the Intervention-Specific Appendix (ISA) that reflects their current PAP usage. Participation in the study will last about 76 weeks.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

- Have been on PAP therapy for at least three consecutive months prior to screening and plan to continue PAP therapy during the study
Exclusion criteria
- Have a prior or planned surgical treatment for obesity (liposuction, cryolipolysis, or abdominoplasty allowed if performed \>1 year before screening)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
