Prevention and early detection for people at high cancer risk
This study looks at surveillance (watching closely), prevention, and early “interception” steps to lower the chance that cancer will develop or be found later. It is for people with genetic risk, past cancer treatment exposures, strong family history, or certain early pre-cancer or high-risk conditions.
Boston, MassachusettsAges Any age - NCT04942717Recruiting
Talking about health values with Spanish or English-speaking patients
This study tests an approach for discussing and sharing what patients value about their health, and adapting it for Latinx communities. It involves separate interviews with patients, families/caregivers, and oncology clinicians to improve how the intervention works and is understood.

Duarte, CaliforniaAges 18 years+ - NCT04898790Recruiting
Testing ways to improve thinking after bone marrow transplant
This study looks at whether a physical activity program and related study measures can improve thinking and memory in older adults around the time of a stem cell transplant. If you qualify and participate, the team will compare outcomes between groups to see what approach works best.
Omaha, NebraskaAges 19 years+ - NCT04867317RecruitingPhase 3
Growth hormone treatment for veterans with mild traumatic brain injury and hormone deficiency
This study tests whether giving growth hormone, a natural substance that helps the body grow and repair tissues, can improve symptoms in veterans who have both a mild traumatic brain injury (concussion) and a deficiency in growth hormone. If you qualify, you may receive the treatment or a placebo (inactive shot), and the study will track your quality of life and symptoms over time.
Birmingham, AlabamaAges 21–55 - NCT04792931Recruiting
Study for adults with suspected autoimmune muscle disease
This study looks at adults who may have an autoimmune (self-immune) muscle disease. It aims to better understand and evaluate this condition, which may help guide future diagnosis and care.
BrestAges 18 years+ - NCT04573140RecruitingPhase 1
RNA vaccine study for newly diagnosed adult and pediatric brain tumors
This Phase 1 trial studies an “RNA-lipid particle” vaccine given after surgery for certain newly diagnosed brain cancers (glioblastoma in adults, high-grade glioma in children/teens). The goal is to see whether the vaccine is safe and can train the immune system to fight the tumor.
Washington D.C., District of ColumbiaAges 4 years+ - NCT04427384Recruiting
Brain tumor patients treated with GammaTiles registry
This study is a patient registry for people with brain tumors who had surgery to remove as much as safely possible and then had GammaTiles placed. It mainly collects information and follow-up imaging to understand how patients do after the treatment.
Phoenix, ArizonaAges Any age - NCT04373473RecruitingPhase 2
Oral stool treatment to prevent ulcerative colitis flare-ups
This study tests whether taking freeze-dried (lyophilized) donor stool material by mouth can help prevent ulcerative colitis from coming back or causing intestinal inflammation. Participants are in remission and stay on their usual treatment while receiving the study product.
Houston, TexasAges 18 years+ - NCT04050280RecruitingPhase 2
Testing an antibody drug for relapsed or hard-to-treat AML
This trial studies a drug called CLAG-GO (an antibody with chemotherapy drugs attached) in adults with AML that has come back or did not respond to treatment. It aims to improve outcomes for people whose leukemia is persistent, relapsed, or refractory.
Baltimore, MarylandAges 18 years+ - NCT03510442Recruiting
Study of genetics and causes of systemic juvenile arthritis and Still's disease
This study aims to learn more about the causes and genetics of two related inflammatory conditions: systemic juvenile idiopathic arthritis (sJIA) in children and adult-onset Still's disease (AOSD) in adults. By studying patients and healthy volunteers, researchers hope to understand these diseases better and find better ways to treat them.

Nivolumab after mismatched bone marrow transplant for sarcoma
This trial studies nivolumab (an immune treatment) in people with sarcoma who already had a partially mismatched bone marrow transplant. It may help the new immune system recognize and attack cancer, and researchers will also watch closely for side effects like GVHD (immune reaction after transplant) and autoimmune problems.

Common questions
- Are there clinical trials for adult?
- Yes. Clin2 currently lists 3,746 recruiting adult 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 adult 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 adult 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.
