Recruiting studies
- NCT04615013RecruitingPhase 1

Computer-based treatment for social anxiety disorder
This study is testing a computer-based treatment for social anxiety disorder. It may help reduce anxiety in social situations through a structured online program, and it also includes brain imaging (MRI) to see how the treatment affects the brain.
New York, New YorkAges 18–60 - NCT04528355Recruiting
Study of hospital data after stem cell transplant for non-cancer illness
This study collects medical information from people with certain non-cancer conditions who receive a stem cell transplant. It may help doctors better understand transplant outcomes and care, since the study focuses on data collection rather than adding new treatment.
Pittsburgh, PennsylvaniaAges 2 months–60 years - NCT04569448RecruitingPhase 3
Brexpiprazole for bipolar depression that won’t improve
This Phase 3 study tests whether brexpiprazole can help treat bipolar depression that has not responded to previous treatments. It compares the study medicine to a placebo (inactive pill) for people with bipolar I or II depression.
Hamilton, OntarioAges 18–75 - NCT04557891Recruiting
Low-intensity ultrasound for generalized anxiety disorder
This trial tests a non-drug brain treatment using low-intensity focused ultrasound to reduce symptoms of generalized anxiety disorder (GAD). It may help if your anxiety has been moderate to severe and you’ve already tried standard medications without enough relief.
Los Angeles, CaliforniaAges 18–65 - NCT04509102Enrolling by invitationEarly Phase 1
Test added stimulant medicine with rTMS for depression
This early study tests whether adding a stimulant medicine to repetitive TMS (a non-drug brain stimulation) can improve depression. It is aimed at people whose depression has not improved after at least two antidepressant tries.
Los Angeles, CaliforniaAges 18–65 - NCT04532190Recruiting
Testing options beyond standard ADHD treatment
This study looks for alternatives to standard treatment for attention-deficit/hyperactivity disorder (ADHD). It may help by testing a different approach for people who meet specific age, language, and health requirements.
Calgary, AlbertaAges 9–15 - NCT04540107RecruitingPhase 1
MRI scan study to characterize lower-grade brain tumors
This Phase 1 study uses special MRI scans (including a form of MR spectroscopy) to better understand lower-grade gliomas. It is designed to test how well the imaging can “characterize” the tumor and to improve understanding for treatment planning.
San Francisco, CaliforniaAges 18 years+ - NCT04421248RecruitingPhase 4
Testing blood or brain markers in kids with ADHD
This Phase 4 study checks whether certain markers change in the brain/body when children with ADHD take methylphenidate (a stimulant). It also compares these markers with healthy children to better understand ADHD.
Baltimore, MarylandAges 8–12 - NCT04414046RecruitingPhase 2
Stem cell transplant using T-cell cleanup for immune and metabolism disorders
This Phase 2 study tests a specialized stem cell transplant that removes certain “T-cells” (a type of immune cell) to treat children with serious immune system or inherited metabolic problems. The goal is to improve or stabilize disease by resetting the immune system and supporting the body’s function.
St. Petersburg, FloridaAges Up to 21 years - NCT04356469RecruitingPhase 2
Donor stem cell transplant for serious blood disorders in children
This trial tests a special type of donor stem cell transplant (with donor T-cells removed) to treat serious non-cancer blood problems in children. It may help by resetting the bone marrow so the body can make healthy blood cells again.
St. Petersburg, FloridaAges birth–21 years - NCT04120701RecruitingPhase 3
Using blood DNA tests to guide colon cancer treatment after surgery
This trial tests whether a blood test that looks at cancer DNA can help decide whether you need “adjuvant” (extra) chemotherapy after colon cancer surgery. It may help some patients avoid unnecessary chemotherapy while still keeping the cancer from coming back.
DijonAges 18–75 - NCT03736538Enrolling by invitationPhase 1
Nitrous oxide for suicidal thoughts in depression
This Phase 1 study tests whether breathing nitrous oxide can safely reduce suicidal thoughts in adults with major depression. It may help people whose depression is causing moderate to severe suicidal thinking, by studying a fast-acting treatment approach.
St Louis, MissouriAges 18–65 - NCT03594630RecruitingEarly Phase 1
Watchful waiting then chemotherapy before surgery for rectal cancer
This trial studies whether a period of active surveillance (watching closely) and chemotherapy before surgery can improve outcomes for people with stage II–III rectal cancer. You would also receive standard chemo-radiation if you qualify, then proceed to surgery.
Houston, TexasAges 18 years+ - NCT03601702Recruiting
EmboTrap device for large stroke blockages
This trial studies whether a specific clot-removal device (EmboTrap II) works well for acute stroke caused by a large artery blockage. It may help restore blood flow faster in people who have certain scan patterns and can be treated within 12 hours.
MilanAges 18 years+ - NCT03065335RecruitingPhase 1
Ketamine plus brain imaging to study response in depression
This early-stage study tests how ketamine given once and then repeatedly may change brain signals and related biomarkers in people with major depression. If you’re eligible, the team will use brain imaging and assessments to see who responds and why.
Bethesda, MarylandAges 18–65 - NCT02695953Enrolling by invitation
Study brain changes after trauma-focused therapy for PTSD
This study looks at how the brain works and how it changes after Cognitive Processing Therapy (CPT) for people with PTSD. You might help researchers learn why this therapy helps and who may benefit most.
Belmont, MassachusettsAges 18–55 - NCT02918474Recruiting
Decision tool for mastectomy choices in new breast cancer
This study tests a decision-making tool to help people with newly diagnosed breast cancer make choices about removing the other (opposite) breast as a preventive step. It may help you think through risks and options in a clearer, more structured way.
Houston, TexasAges 18 years+ - NCT02966665RecruitingPhase 1
Testing blood vessel function in people of different health conditions
This early study measures how well your blood vessels work using tests that may include MRI. It compares healthy people with people who have conditions like COPD, pulmonary arterial hypertension, heart failure, or high blood pressure, to better understand “vascular function” in health and disease.
Salt Lake City, UtahAges 18 years+ - NCT00567073Recruiting
Register pregnant people with Pompe disease for pregnancy data
This study keeps a special record of pregnancies in people with Pompe disease to learn more about pregnancy outcomes and newborn information. It does not test a drug by itself—it collects health information to improve future care.
Phoenix, ArizonaAges Any age - NCT00001238Recruiting
Understanding kidney cancer genes in families
This research study helps doctors understand inherited kidney cancers and related conditions that run in families. Researchers collect medical information and blood samples to identify genetic causes and improve how these conditions are diagnosed and treated.
Bethesda, MarylandAges 2 years+ - NCT06638944RecruitingPhase 2
Wearable feedback device for swallowing therapy in stroke or Parkinson's
This study tests a wearable device that provides feedback to help improve swallowing in people with stroke or Parkinson's disease. It may help make swallowing therapy more effective by showing real-time progress during exercises.

Chemotherapy with or without vaccine for HPV-related throat cancer
This trial compares standard chemotherapy alone versus chemotherapy combined with an investigational vaccine (PRGN-2009) before surgery for newly diagnosed HPV-positive oropharyngeal (throat) cancer. The goal is to see if adding the vaccine improves outcomes.
