Recruiting studies
- NCT04478838RecruitingPhase 4
Alternate-day antipsychotic dosing for schizophrenia
This trial looks at whether taking an antipsychotic every other day can keep symptoms controlled in adults with schizophrenia or another psychotic disorder. It may help some people avoid daily dosing, but it requires specific medication stability and screening checks.

Quality of life check for people with melanoma during COVID-19
This study looks at how people with melanoma are feeling during the COVID-19 pandemic, including quality of life. You may be asked to share information through surveys or study contact so the researchers can understand needs and concerns.
Houston, TexasAges Any age - NCT04458532Recruiting

This trial studies whether a structured exercise program can improve cardiovascular (heart and blood vessel) health in post-menopausal women after early-stage breast cancer treatment. It specifically targets women who have trouble with exercise and have completed cancer treatment within the last 1 to 5 years.
Hartford, ConnecticutAges 21–80 - NCT04388332Recruiting
Neck surgery compares two bone graft materials
This study compares two materials used during neck surgery for degenerative disc disease: donor bone (structural allograft) versus a titanium cage (Tritanium C). It aims to see which option works better for healing the fused neck bones and improving symptoms.
Pittsburgh, PennsylvaniaAges 18–80 - NCT04477928Recruiting

Whole-body PET scans in people with multiple sclerosis
This early study tests how whole-body PET-CT scans can be used in people with multiple sclerosis (and compares with healthy volunteers). It may help researchers understand what the scan can show in MS throughout the body.
Ladera Ranch, CaliforniaAges 25–55 - NCT04410302Recruiting
Personalized tumor research for bladder, lung, stomach, and liver cancers
This study uses a small sample of your tumor to grow it in the lab, which may help researchers understand your cancer better and find treatments that work for you.
Orange, CaliforniaAges 21–100 - NCT04485559RecruitingPhase 1
Trametinib and everolimus for recurrent gliomas
This trial tests two drugs, trametinib and everolimus, for children and young adults with recurrent or progressive gliomas (a type of brain tumor). The goal is to see if this drug combination is safe and effective in treating these tumors.
Birmingham, AlabamaAges 1–25 - NCT04419480Recruiting
Monitoring to help prevent complications after cardiogenic shock
This study tests a special monitoring approach (likely using an implanted device) to help prevent serious complications after you survive cardiogenic shock in the hospital. It may help the care team detect problems earlier so treatments can start sooner.
Falls Church, VirginiaAges 18 years+ - NCT03852381Recruiting
Spinal cord stimulation for nerve pain after back surgery
This study looks at how spinal cord stimulation (a device that sends mild signals to the spinal cord) affects nerve pain after lumbar surgery. It also aims to help predict who is most likely to improve and why, comparing patients with and without certain sensory symptoms.
Toronto, OntarioAges 18–80 - NCT04299022Recruiting
Study of ViviGen bone graft for fracture healing
This study follows people who are treated with a bone graft called ViviGen to help heal fractures, delayed healing, or non-healing (“non-union”) bone problems. The goal is to check how safe it is and how well it works in real-world orthopaedic care.
Orlando, FloridaAges Any age - NCT04347200Recruiting
Long-term blood-thinner therapy registry for heart disease
This study follows people with known coronary artery disease to understand how long-term “blood thinner” treatments are used and how they affect health over time. You may be asked to share medical information and come in for follow-up to help researchers compare outcomes.
MoscowAges 18 years+ - NCT04347187Recruiting
Long-term blood-thinner study for atrial fibrillation patients
This trial follows people with atrial fibrillation to see how long-term blood-thinning treatment affects outcomes over time. It may help determine which long-term approach best lowers stroke and clot risks for patients like you.
MoscowAges 18 years+ - NCT04374799RecruitingPhase 3
Heparin vs placebo during cardiac catheterization
This trial tests whether giving heparin (a blood thinner) during a specific type of heart procedure is safer and works better than not giving it. It focuses on patients where the blood supply in the hand’s artery connection is functioning properly.
Hamilton, OntarioAges 18 years+ - NCT04354077Recruiting
Deep brain stimulation for opioid addiction
This study tests whether deep brain stimulation (DBS), a surgical treatment that uses electrical pulses to target specific brain areas, can help reduce cravings and relapse in people with opioid use disorder who haven't found relief from other treatments.
Pittsburgh, PennsylvaniaAges 22–65 - NCT04367857Recruiting
Study of COVID antibody levels in healthcare workers
This study measures how many healthcare workers have COVID antibodies (proof of past infection or immune response). Results may help estimate how widespread COVID exposure has been among hospital staff.
New York, New YorkAges 18 years+ - NCT04326192Recruiting
Spinal cord stimulation to reduce stubborn back and leg pain
This trial tests whether spinal cord stimulation (a treatment where a device sends mild signals to the spinal cord) can improve persistent nerve-type back and leg pain. It is mainly for adults who are already planning to try spinal cord stimulation but have not tried it before.
Portland, OregonAges 21–70 - NCT04348318Recruiting
Evaluating an advance care plan for ICU patients
This study looks at how well advance care planning documents are put into action for people who stay in the intensive care unit (ICU). If you participated, it may help the hospital improve how patients’ wishes are followed during serious illness.
