A Drug-Drug Interaction Study of Orforglipron (LY3502970) in Healthy Overweight and Obese Participants

United States50 participantsStarted 2024-01-02

Plain-language summary

The main purpose of this study is to determine effect of orforglipron capsule formulation on the amount of digoxin, rosuvastatin, acetaminophen, midazolam, and simvastatin (each given alone and together with orforglipron) that enters the bloodstream and how long it takes the body to eliminate them when administered orally in healthy overweight and obese participants. In addition, the effect of the orforglipron tablet on the amount of simvastatin that enters the bloodstream and how long it takes the body to eliminate it will be evaluated. The study will also assess the effect of sodium bicarbonate when administered alone with simvastatin versus orforglipron capsule containing sodium bicarbonate administered with simvastatin. The safety and tolerability of orforglipron and information about any side effects experienced will be collected. Study will be conducted in two parts, with part 1 and 2 lasting up to approximately 23 and 24 weeks each, including the screening period.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
