Using HPV blood test to guide treatment for HPV throat cancer
This Phase 2 study tests a “risk-adapted” treatment plan for HPV-related throat cancer, using an HPV DNA blood test to help decide how treatment is done. If your baseline blood test shows detectable HPV DNA, the study may help tailor therapy to your risk and potentially improve outcomes while limiting unnecessary treatment.
Boston, MassachusettsAges 22 years+ - NCT04972136Recruiting
Brain stimulation treatment for depression in young adults with autism
This trial studies a noninvasive brain stimulation (rTMS) to help reduce depression symptoms in young adults who have autism. It aims to find out if this treatment can improve mood and daily functioning without requiring recent changes to medications.
Toronto, OntarioAges 16–35 - NCT04984512RecruitingPhase 2/Phase 3
Testing mitizodone tablets for major depression symptoms
This trial studies whether mitizodone phosphate tablets can improve symptoms of major depressive disorder (MDD). It also checks the treatment’s safety, including mood and physical health effects.
Dongguan, GuangdongAges 18–65 - NCT05028140RecruitingPhase 3
Testing a lifestyle-and-diet program for type 2 diabetes control
This Phase 3 study tests whether a program run by the Piemonte Association can improve blood sugar control in people with type 2 diabetes who haven’t reached their target after usual diet, exercise, and stable medicines. It also aims to check that the approach is safe for participants.
Hortolândia, São PauloAges 18–85 - NCT05051618Recruiting
Exercise program for depression in people with multiple sclerosis
This trial studies whether a structured exercise program can help reduce symptoms of major depressive disorder in people who also have multiple sclerosis. You’ll complete questionnaires, wear an activity sensor, and do exercise testing while being assigned to the study program.
Chicago, IllinoisAges 18–64 - NCT05086614RecruitingPhase 3
Thymosin-alpha 1 after surgery for high-risk colon cancer
This trial looks at whether thymosin-alpha 1, an immune-support treatment, can help prevent colon cancer from coming back after surgery. It targets people with high-risk stage II or III colon cancer who have had the tumor removed.

- Yes. Clin2 currently lists 2,377 recruiting bipolar disorder i or ii 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 bipolar disorder i or ii 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 bipolar disorder i or ii 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.
