Recruiting studies
- NCT05368662Recruiting
Studying sleep and life quality in children on home ventilation

Spinal cord stimulation study for long-term chemotherapy nerve pain
This trial tests whether spinal cord stimulation can reduce pain and improve quality of life in people with long-lasting nerve pain from chemotherapy (CIPN). You must already have tried at least two nerve-pain medicines and still have significant pain, and you must have had a successful spinal cord stimulator test before joining.

Biobank study for ANCA-associated vasculitis patients
This study collects and stores health information and possibly samples from people diagnosed with ANCA-associated vasculitis to help researchers learn more about the disease. It may help future studies, but it is mainly focused on collection rather than testing a new treatment.
Brest, BrestAges 18–99 - NCT05379153RecruitingPhase 3
Laser therapy for vaginal dryness in breast cancer survivors
This trial tests whether laser therapy can help women who have had breast cancer and now experience vaginal dryness. It aims to see if this treatment can reduce dryness and improve comfort.
Ann Arbor, MichiganAges 22 years+ - NCT05388019Enrolling by invitation
VAD clinic visit study for new and returning patients
This trial looks at how well a specialized, multidisciplinary clinic works for people who have a ventricular assist device (VAD) and compares new VAD patients with those who have already had standard follow-up visits. It may help improve how care and check-ins are organized after your VAD is implanted.
Boston, MassachusettsAges 18 years+ - NCT05408845RecruitingPhase 2
Study drug vs standard care for HER2 salivary gland cancer
This Phase 2 trial tests how well ado-trastuzumab emtansine (and compares to two standard treatment options) works for salivary gland cancers that are HER2-positive or HER2-low. It aims to see whether the study drug can control cancer better and with acceptable side effects.
Birmingham, AlabamaAges 18 years+ - NCT05349513Recruiting
Testing a home-care program for schizophrenia-like disorders
This study tests a specific kind of care delivered in a home-like setting for people with schizophrenia or schizoaffective disorder. It may help the care team understand what kinds of supports work best and improve day-to-day treatment.
PoitiersAges 18–65 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT05327608Recruiting
Time-restricted eating during chemo before breast cancer surgery
This study tests whether eating only during a certain window of time each day (time-restricted eating) can improve outcomes for people with early-stage breast cancer who are getting chemotherapy before surgery. It may help with treatment side effects and overall health.
Cherry Hill, New JerseyAges 18 years+ - NCT05285358RecruitingPhase 1
Aerosol chemo plus standard drugs for bile duct and gallbladder cancer
This trial tests a new way to give the drug paclitaxel directly into your belly as a mist, along with two standard chemo drugs given through your veins, for bile duct or gallbladder cancer that has spread to the lining of the belly. The goal is to see if this approach can better control the cancer in the belly.
Duarte, CaliforniaAges 18 years+ - NCT05284006Recruiting
Non-invasive tests for Morquio A
This trial studies Morquio A (MPS IVA) using non-invasive ways to measure how the body is working, and to better understand why the condition happens. If you have Morquio A, this may help researchers learn more and improve care.
Wilmington, DelawareAges Any age - NCT04911036Recruiting
Compare parent stress after diagnosis before versus after birth
This study looks at how the timing of a baby’s diagnosis—before birth (antenatal) versus after birth (postnatal)—affects parents’ stress and emotional reactions after their child has surgery. You may be able to contribute by sharing experiences as a parent of a child who had this specific surgery.
LilleAges 18 years+ - NCT05235165RecruitingPhase 3
Surgery choice for lung spread of osteosarcoma
This Phase 3 trial compares two ways to remove lung metastases (open surgery vs keyhole surgery) in people with osteosarcoma. It aims to see which approach works better and is safer for patients with a limited number of lung spots that can be removed.
Birmingham, AlabamaAges Up to 50 years - NCT05236803Recruiting
Assessing motor problems in autistic children
This study aims to better understand how motor skills (movement and coordination) work in children with autism spectrum disorder. It uses an assessment approach to help researchers understand what motor difficulties look like, which may improve future evaluations and support.
BordeauxAges 6–11 - NCT05200182Recruiting
Brain training to improve control over emotional eating
This study tests a brain training technique (neurofeedback) that may help improve self-control related to emotional eating. If you tend to eat more when stressed or upset, this could help you manage those urges.
RennesAges 18–50 - NCT05231122RecruitingPhase 2
Pembrolizumab and bevacizumab for recurrent ovarian cancer
This trial studies whether adding pembrolizumab to bevacizumab (and sometimes an anti-CD40 drug) can help control recurrent ovarian, fallopian tube, or primary peritoneal cancer. It also looks at whether the treatment can shrink tumors and keep them from growing for longer.

Common questions
- Are there clinical trials for questionnaire?
- Yes. Clin2 currently lists 1,134 recruiting questionnaire 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 questionnaire 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 questionnaire 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.
