Deep health study of Gulf War veteran symptoms and brain-body changes
This study closely measures health, thinking, and body function in Gulf War veterans using detailed testing (including exercise testing and possibly brain scans). It aims to better understand what may be driving Gulf War illness and related symptoms, which could improve future care.
Bethesda, MarylandAges 48–70 - NCT05370391Recruiting
Behavior therapy for youth tics with parent involvement
This study tests a structured behavior-based therapy (CBIT) to help reduce tic symptoms that interfere with daily life. You and a parent/caregiver work together during visits and questionnaires to see if treatment helps.
Coral Gables, FloridaAges 5–17 - NCT05365035RecruitingPhase 2
Phase 2 trial for high-risk blood cancers with timed chemo
This study tests a mix of medicines (cladribine, low-dose cytarabine, and venetoclax) alternated with azacitidine and venetoclax to treat higher-risk CMML or MDS after prior treatment or when standard treatment may not work well. It may help by improving blood counts and controlling the disease.
Houston, TexasAges 18 years+ - NCT05377125Recruiting
Training brain skills to reduce urges in OCD spectrum
This study tests a training program meant to improve “response inhibition,” the brain’s ability to pause before acting on unwanted urges. It may help people with OCD-spectrum conditions like obsessive-compulsive disorder, trichotillomania (hair pulling), or skin picking by targeting brain control of impulses.
Milwaukee, WisconsinAges 18–60 - NCT05361798RecruitingPhase 2
Testing immune response after prostate radiation with or without a drug
This study checks how your immune system’s cancer-fighting cells change after stereotactic body radiation (SBRT) to the prostate. It compares SBRT alone versus SBRT plus an immunotherapy drug (PDS01ADC) in men with intermediate- or high-risk localized prostate cancer treated with hormone therapy (ADT).
Bethesda, MarylandAges 18 years+ - NCT05334706RecruitingPhase 4
Vaccine study to lower HPV spread in HPV-positive women
This Phase 4 study tests whether a 9-type HPV vaccine (9vHPV) can reduce how infectious HPV is and lower the chance of HPV spreading in women who already have HPV16 and/or HPV18. It focuses on specific HPV-positive women recently diagnosed and compares what happens after vaccination.
L'Hospitalet de Llobregat, CataloniaAges 18 years+ - NCT05346848RecruitingPhase 2
Darolutamide plus radiation for intermediate-risk prostate cancer
This trial tests whether adding darolutamide to standard radiation can better control intermediate-risk prostate cancer. It includes men whose cancer has spread nowhere else and who are newly diagnosed with “unfavorable intermediate risk” or progress to that risk group.
AvignonAges 18 years+ - NCT05360160RecruitingPhase 1/Phase 2
Oral menin inhibitor plus AML medicines for new or relapsed AML
This trial tests an all-pill (oral) combination treatment—menin inhibitor SNDX-5613 plus decitabine/cedazuridine (ASTX727) and venetoclax—for acute myeloid leukemia (AML). It’s designed for people who are newly diagnosed and can’t get the strongest chemotherapy, or for certain other AML groups who may still benefit.
Houston, TexasAges 12 years+ - NCT05327699RecruitingEarly Phase 1
Ketamine study for depression with reduced pleasure
This early-phase study tests whether ketamine can help people with major depression who have trouble feeling pleasure. It also studies how the brain may change in response to stress, to better understand who might respond to treatment.

Azacitidine plus pembrolizumab for Hodgkin lymphoma after relapse
This Phase 2 study tests azacitidine together with pembrolizumab in people whose Hodgkin lymphoma has come back or did not respond (relapsed/refractory). It aims to see whether this combination can control cancer and improve outcomes, especially when standard high-dose chemotherapy is not an option.
Houston, TexasAges 1 year+ - NCT05345158Recruiting
Robotic surgery first for early-stage seminoma testicular cancer
This trial studies whether a robotic operation (removing cancerous lymph nodes in the back of the belly) is a good first treatment for certain early-stage testicular seminoma cases. It aims to cure cancer while avoiding or delaying other treatments, and uses follow-up plans to check results.

Common questions
- Are there clinical trials for bipolar disorder i or ii?
- Yes. Clin2 currently lists 2,350 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.
