Enzalutamide plus relacorilant versus placebo for high-risk prostate cancer
This study tests whether adding relacorilant to enzalutamide (a hormone-blocking treatment) helps control high-risk localized prostate cancer better than enzalutamide plus a dummy pill. It may help prevent the cancer from growing or spreading by targeting a hormone pathway in addition to standard treatment.
Chicago, IllinoisAges 18 years+ - NCT05727761RecruitingPhase 2
Pioglitazone plus metformin for high-risk mouth lesions
This trial studies whether a two-medicine diabetes drug combination can reduce or control risky early changes in certain mouth and throat lesions. You may be asked for small tissue samples (biopsies) before and after 12 weeks to see how the lesions respond.
Minneapolis, MinnesotaAges 18 years+ - NCT05662462Recruiting
Phone coaching to keep blood sugar in range during pregnancy
This study tests whether technology plus coaching can help pregnant people with type 2 diabetes keep their blood sugar in a healthy target range. You may use a smartphone app and, if assigned to that group, a device that tracks glucose continuously.
Columbus, OhioAges 18 years+ - NCT05650749Enrolling by invitationPhase 1
GPC2 car T cells for neuroblastoma and retinoblastoma
This trial tests a new treatment using engineered immune cells (CAR T cells) that target a protein called GPC2 found on some cancer cells. It is for patients with high-risk neuroblastoma or metastatic retinoblastoma that has returned or not responded to other treatments.
Philadelphia, PennsylvaniaAges 1 year+ - NCT05620771RecruitingPhase 2
Y-90 radioembolization plus treatment for high-risk liver cancer

Common questions
- Are there clinical trials for clinical high risk?
- Yes. Clin2 currently lists 551 recruiting clinical high risk studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a clinical high risk trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a clinical high risk trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
