Itraconazole with ablation to prevent esophageal cancer in Barrett's esophagus
This trial tests if adding the antifungal drug itraconazole to standard ablation therapy can help prevent esophageal cancer in people with high-risk Barrett's esophagus. You must have a confirmed diagnosis of Barrett's esophagus with low- or high-grade dysplasia or early-stage cancer, and be planning to have ablation treatment.
Kansas City, KansasAges 18 years+ - NCT04939051RecruitingPhase 2

NantesAges 8–14 - NCT04959474Recruiting
Pre-surgery radiation study with or without calorie restriction
This trial looks at whether a planned calorie-reduction diet before surgery can change how early breast cancer responds to a short course of radiation. It may help people understand if diet could improve outcomes alongside standard pre-surgery treatment.
Philadelphia, PennsylvaniaAges 40 years+ - NCT04984551RecruitingPhase 2
Training plus support to improve palliative care for advanced cancer
This trial studies whether a program called Project ECHO can improve the quality of palliative care (comfort-focused care) for people with advanced cancer and their caregivers in underserved areas. It also involves training local health care providers so they can better support patients and families over time.
Houston, TexasAges Any age - NCT04987814Recruiting
Testing a skin-sensor scan to detect muscle loss
This study uses a high-detail sensor placed on the skin to look for signs of sarcopenia, or age-related muscle loss. The goal is to see whether the scan can help diagnose sarcopenia more accurately.
Ivry-sur-SeineAges 75 years+ - NCT04993469Recruiting
Tracking genital comfort after gender-affirming surgery
This study asks people who are planning genital gender-affirming surgery to report how their genital sensitivity and sexual function feel afterward. It helps doctors understand what changes patients experience and improve follow-up care.
Ghent, East-FlandersAges 18–110 - NCT04997642Recruiting
Parkinson’s patient database for memory and movement tracking
This study builds a research database of people who receive care for Parkinson’s disease, including those with mild memory problems or dementia. It aims to collect consistent information that researchers can use to better understand Parkinson’s and related thinking changes.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05006482RecruitingPhase 3
Geriatric education and care support for older cancer survivors
This study tests whether a structured health education and “older adult care” approach—done with your oncology team—can improve support for people after cancer. It includes older cancer survivors and a chosen caregiver, using in-person or video visits for follow-up.
Tuscaloosa, AlabamaAges 18 years+ - NCT05008497Recruiting
Cancer patients’ health literacy research at a specific hospital
This study looks at patients’ health literacy—how well people understand and use health information—among adults receiving care for cancer. It’s mainly for people who are followed at a particular hospital and who agree to have their medical data used.
ParisAges 18 years+ - NCT05009758Recruiting
Asthma and nasal polyps study to match immune patterns
This study looks at different “immune inflammation patterns” in people with asthma and/or nasal polyps. It may help researchers better tailor future treatments by figuring out which patterns go with which symptoms.
ViennaAges 18–99 - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05010265Recruiting
Learning how to detect hidden awareness using brain signals
This study explores an ethical approach to detecting “covert consciousness,” meaning a person may be aware even if they cannot show it clearly. It involves people connected to patients with disorders of consciousness, including caregivers and specialists, and uses information related to MRI or EEG brain testing done for clinical care.
Boston, MassachusettsAges 18 years+ - NCT05011045Recruiting
Brain radiation study tracking thinking and memory changes
This study looks at how whole-brain radiation affects thinking, memory, and other brain function in people with blood cancers that involve the brain. It may help doctors understand what to expect and which supportive treatments or monitoring could be useful.
Houston, TexasAges 18 years+ - NCT05014165Recruiting
Cord blood study for leukemia with stored birth samples
This study looks at leukemia “genetic clues” using special stored samples, including cord blood saved at birth. It may help researchers better understand leukemia biology and how common mutations may show up early.
Minneapolis, MinnesotaAges Up to 25 years - NCT05026983RecruitingPhase 2
Targeted drugs for melanoma spread to the brain
This Phase 2 trial tests two targeted medicines (binimetinib and encorafenib) for melanoma that has spread to the brain. It focuses on people whose tumor has a specific BRAF V600 mutation and who have brain metastases that are progressing or need treatment.
Houston, TexasAges 18 years+ - NCT05044689Recruiting
Study to find risk factors for breast and colon cancer
This study is trying to understand what factors might raise the risk of breast cancer and colon (large bowel) cancer. You may be enrolled either if you have a confirmed cancer diagnosis (cases) or if you do not have cancer (controls).
Ile-Ife, Osun StateAges Any age - NCT05054296RecruitingPhase 2
Exercise and Fitbit monitoring to lower heart risk in prostate cancer
This Phase 2 study tests whether a structured exercise and lifestyle program, tracked with a Fitbit, can reduce cardiovascular (heart) risk in men with prostate cancer on hormone therapy. It also checks whether this is safe and feasible while monitoring symptoms and fitness changes.
Houston, TexasAges 18 years+ - NCT05054413Recruiting
Expert guideline survey for prostate cancer care
This study uses a structured expert survey to help build clear, agreed-upon guidelines for prostate cancer care. If you’re a board-certified clinician who actively treats prostate cancer, your input can help shape how care is recommended.

Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues. You might be offered a chance to help doctors understand why some people get longer or more intense symptoms from infectious mononucleosis.
