Recruiting studies
- NCT04524585Recruiting
Tested a muscle-relaxing treatment for severe low-oxygen breathing

North Brunswick, New JerseyAges 18 years+ - NCT04539951RecruitingPhase 2
Trial for newly treated obsessive-compulsive disorder
This phase 2 study tests an OCD treatment strategy for people who have not yet had OCD medications or recent OCD therapy. It aims to reduce OCD symptoms, especially for those with moderate-to-severe symptom levels.
Shanghai, Shanghai MunicipalityAges 18–65 - 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+ - NCT04543461Recruiting
Lung health study for young adults in the U.S.
This study follows young adults to learn about lung health and risk factors. It may help researchers better understand how breathing symptoms and exposures affect future lung outcomes.
Birmingham, AlabamaAges 25–35 - NCT04550377RecruitingPhase 2
Cannabidiol for PTSD, including PTSD after mild head injury
This Phase 2 study tests whether cannabidiol (CBD) can reduce PTSD symptoms, including in people who also had a mild traumatic brain injury (TBI). It’s meant to see if CBD is helpful and safe for PTSD symptoms over the study period.
New York, New YorkAges 18–70 - NCT04559230RecruitingPhase 2
Treating recurrent glioblastoma with sacituzumab govitecan
This Phase 2 study tests sacituzumab govitecan in adults whose glioblastoma has come back after standard treatment (radiation plus temozolomide). It may help shrink the tumor in people whose tumor has a specific target (Trop-2).
Cleveland, OhioAges 18 years+ - NCT04559919Recruiting
Building a regional database for people with epilepsy
This study collects information about adults who have had an unprovoked seizure or who have epilepsy. The goal is to better understand epilepsy in the community and improve future care.
BoråsAges 18 years+ - NCT04570020Recruiting
Check how well wide-view scans guide scleral lens fitting
This study tests whether a special wide-area eye scan (OCT) can help fit scleral contact lenses more accurately. It may help people who need scleral lenses because of certain cornea shape problems or after past eye surgeries.
Portland, OregonAges 18 years+ - NCT04570553Recruiting
Testing a tool during surgery for early endometrial cancer
This study looks at how well a surgical tool is used during standard surgery for early endometrial cancer, and whether it relates to test results from fluid taken in the abdomen. It may help surgeons improve how samples are collected and interpreted during routine care.
York, PennsylvaniaAges 18 years+ - NCT04573062Recruiting
Study how people recover from COVID over time
This study follows adults who recently recovered from COVID-19 to better understand what happens during recovery and afterward. It may help researchers identify who is at risk for longer-lasting symptoms (often called “PASC”) and what changes over time.
Bethesda, MarylandAges 18–100 - NCT04574440Recruiting
Near-infrared brain scan during planned heart surgery
This trial tests a non-painful near-infrared brain scan (placed on the forehead) during planned adult heart surgery. It may help doctors better understand how the brain responds during surgery and improve care.
London, OntarioAges 18 years+ - NCT04574960RecruitingPhase 3
Neoadjuvant chemotherapy before kidney/ureter cancer surgery
This Phase 3 trial studies giving cisplatin-based chemotherapy before surgery for certain newly diagnosed upper-urinary-tract urothelial cancers (kidney/ureter). It may help shrink the cancer and improve outcomes by treating microscopic disease earlier.
Ottawa, OntarioAges 18 years+ - NCT04577599Recruiting
Mobile low-dose lung CT screening for ages 40–54
This study offers mobile low-dose CT scans to help find lung problems early in people at higher risk from smoking. You may be invited because of your age and smoking history, and the results may guide next steps with your care team.
Charlotte, North CarolinaAges 40–54 - NCT04583150Recruiting
Study of fertility and ovarian reserve after weight-loss surgery
This study looks at how ovarian reserve (a fertility-related marker) changes in women after bariatric (weight-loss) surgery versus women with obesity who are not planning surgery. It may help doctors better understand fertility timing and risks around weight-loss treatment.
AngersAges 18–37 - NCT04583254RecruitingPhase 2
Shorter radiation plan for certain early cervical cancers
This trial tests a feasibility (“can it be done safely?”) approach that delivers radiation in a shorter schedule for some cervical cancer patients. It also uses weekly cisplatin chemotherapy and includes a radiation procedure called brachytherapy to improve treatment effectiveness.
Kelowna, British ColumbiaAges 18 years+ - NCT04596592Recruiting
Puberty blockers and estradiol effects on heart health
This study looks at how puberty blockers and then estradiol (estrogen) may affect heart and metabolism health in teens. It may help doctors understand risks and benefits for transgender youth starting gender-affirming hormone care.

Pilot ePNa tool for pneumonia decisions in urgent care
This trial tests and rolls out an electronic support tool (ePNa) to help urgent care clinicians decide how to evaluate and manage pneumonia. It may help by standardizing decision-making so patients get more consistent care.
American Fork, UtahAges 12 years+ - NCT04608357Recruiting
Testing digital patient avatars to guide treatment for metastatic breast cancer
This study tests whether a computer “avatar” made from your health information can help choose the best systemic therapy (medications that treat cancer throughout the body) for metastatic breast cancer. You may be asked to provide a tissue sample (biopsy) so the team can build and guide the treatment plan.
Toronto, OntarioAges 18 years+ - NCT04615104Recruiting
Study of pelvic and hip-joint bone fractures
This study is observing people with pelvic ring and acetabular (hip-joint socket) fractures to better understand what happens over time. It may help doctors improve care, even though it does not test a new treatment.

Common questions
- Are there clinical trials for health?
- Yes. Clin2 currently lists 5,570 recruiting health 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 health 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 health 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.
