A Study of Brenipatide in Adult Participants With Bipolar Disorder (RENEW-Bipolar-1)
A Phase 2, Multicenter, Randomized, Double-Blind, Parallel-Arm Study to Investigate the Efficacy and Safety of Adjunctive Treatment With Brenipatide in Delaying Time to Relapse Compared With Placebo in Adult Participants With Bipolar Disorder (RENEW-Bipolar-1)
A Study of Brenipatide in Adult Participants With Bipolar Disorder (RENEW-Bipolar-1) (NCT07286175) is a Phase 2 interventional studying Bipolar Disorder, sponsored by Eli Lilly and Company. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
The purpose of this study is to assess the efficacy and safety of brenipatide when administered with standard of care (SoC), compared with placebo plus SoC in delaying the worsening of bipolar disorder symptoms. The trial is divided into three periods as follows: Screening period that will last approximately 1 month, treatment period that will last a minimum of 6 months, and the follow up period that will last approximately 2 months. The duration of study participation may vary and may be shortened if bipolar symptoms worsen or if withdrawal from the study occurs for any reason.
What Stage of Research Is This?
Phase 2 trials evaluate whether a treatment actually works against Bipolar Disorder and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
A target enrollment of 400 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Who can participate in NCT07286175?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT07286175?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
