Recruiting studies
- NCT00991094Recruiting
Study follow-up after proton radiation treatment

Gilbert, ArizonaAges 18 years+ - NCT00260559Recruiting
Checks quality of life after esophagus surgery
This study looks at outcomes and quality of life after esophagus removal surgery, comparing minimally invasive surgery and open surgery. It may help doctors understand how different surgical approaches affect how you feel during recovery.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT00005095Recruiting
Ovarian cancer risk study: specimens and health data
This study collects tissue samples and medical information from people at higher risk for ovarian cancer or undergoing gynecologic surgery. Researchers use this data to develop better ways to detect and prevent ovarian cancer early.
Chicago, IllinoisAges 18–80 - NCT01696734RecruitingPhase 3
Domperidone for difficult stomach and reflux problems
This trial studies whether domperidone can help people whose stomach or reflux symptoms did not improve with usual treatments. It focuses on symptoms like slow stomach emptying, hard-to-control acid reflux, or severe indigestion.
Houston, TexasAges 16 years+ - NCT01790152Recruiting
Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.
Birmingham, AlabamaAges Any age - NCT00505245Recruiting
Testing a new way to measure cancer symptom distress
This study tests a new assessment system (a set of questions/tools) to better measure how much distress cancer patients feel from symptoms. It may help cancer teams better understand your symptom burden and improve support.
Houston, TexasAges 18 years+ - NCT00539162Recruiting
CA-125 and other tests to check for early ovarian cancer risk
This study looks at how well a blood test called CA-125, along with other markers and checkups, can detect ovarian cancer early. It’s for women considered low risk who will do regular blood tests and possibly a vaginal ultrasound if results suggest it.
Miami, FloridaAges 50–74 - NCT01194648Recruiting
HIFU treatment for early prostate cancer
This trial studies a focused ultrasound treatment called HIFU for prostate cancer that appears limited to the early stages. It aims to treat cancer within the prostate while avoiding treatment spread to lymph nodes or distant organs.
London, EnglandAges Up to 90 years - NCT01365169Recruiting
How activity level and daily function relate to cancer survival
This study looks at how physical activity (movement during the day) and a clinician-rated “day-to-day function” score relate to overall survival in people with certain cancers. It may help doctors understand who benefits most from activity-focused care and better monitoring.
Houston, TexasAges 18 years+ - NCT01492036Recruiting
Long-term follow-up for people who received gene therapy
This study follows people for many years after they receive gene therapy (a treatment that uses lab-made genetic material). It mainly checks long-term safety and health outcomes and may help doctors understand how gene therapy works over time.
Houston, TexasAges Any age - NCT02107105Recruiting
Study how surgery affects life quality in rectal cancer
This trial studies how surgical treatment for rectal cancer affects patients’ quality of life and other day-to-day impacts. It may help doctors understand what to expect after surgery and how to better support patients.
Houston, TexasAges 18 years+ - NCT02596490Recruiting
Couple meditation program for metastatic lung cancer and partners
This study tests whether a couple-based meditation program can help people with stage IV non-small cell lung cancer and their romantic partners cope better during treatment. It looks at the experience of both the patient and their partner, not just the patient alone.
Houston, TexasAges 18 years+ - NCT02753777Recruiting
Study for blistering autoimmune skin diseases
This study is for adults with certain autoimmune blistering skin conditions. Researchers want to better understand and test treatments that could improve symptoms and healing for people with these specific diseases.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02593565Recruiting
Pregnancy blood-vessel disease registry study
This is a pregnancy registry that collects information from people with certain blood-vessel inflammatory diseases during pregnancy. It helps researchers better understand these conditions in pregnancy and may guide future care.
Tampa, FloridaAges 18–50 - 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+ - NCT02620852Recruiting
Wisdom Study: Women’s breast cancer screening decisions
This study looks at how to decide the best breast cancer screening (like mammograms) based on your personal risk. It may help by testing a smarter way to match screening to your risk level.
Birmingham, AlabamaAges 30–74 - NCT02898818Recruiting
Study of interactions between vaginal and oral microbiomes
This study looks at how the bacteria (microbes) in the vagina and in the mouth may affect each other. It may help improve understanding of vaginal health and related conditions.
Turku, TurkuAges 18 years+ - NCT02701153Recruiting
Short pre-surgery radiation for soft-tissue sarcoma
This trial tests a short course of radiation before surgery to shrink a soft-tissue sarcoma and make it easier to remove. It may help by improving how well the tumor can be removed, while studying safety and effectiveness for this cancer type.
Los Angeles, CaliforniaAges 18 years+ - NCT02705846Recruiting
Study tracks outcomes in men with inherited prostate cancer risks
This study looks at how prostate cancer diagnoses and treatments turn out over time. It compares men who carry rare inherited gene changes that raise prostate cancer risk with men who do not, to better understand which treatments and outcomes may differ.
Sutton, SurreyAges 18 years+ - NCT02706561Recruiting
Helping men stick with erectile rehab after prostate surgery
This study tests a program to help men follow sexual (erection) rehabilitation after prostate cancer surgery. It may help improve or maintain erectile functioning by supporting the right rehab steps in the months after surgery.
New York, New YorkAges 21 years+ - NCT02931513Recruiting
Blood marker test in newly diagnosed PBC patients
This study looks at how a specific blood marker (sCD163) changes in people newly diagnosed with primary biliary cholangitis (PBC). It’s mainly meant to see whether this marker could help predict treatment response, especially before starting UDCA.
Aarhus C, Central JutlandAges 18 years+ - NCT02970045Recruiting

Common questions
- Are there clinical trials for questionnaire?
- Yes. Clin2 currently lists 1,166 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.
