ParisAges 18–90 - NCT05557877RecruitingPhase 2
Low-dose aspirin to prevent postpartum breast cancer
This study tests whether taking a low dose of aspirin after childbirth can lower the chance of developing breast cancer later. You may be asked to provide blood, urine, and breast tissue samples so researchers can look for changes that could explain why aspirin may help.
Scottsdale, ArizonaAges 18–45 - NCT05532865Recruiting
Biobank study for adults with systemic sclerosis
This study follows adults with systemic sclerosis who are being seen at a specific hospital and asks for consent to store blood and other samples for future research. It may help researchers better understand the disease and develop better tests or treatments over time.
BrestAges 18 years+ - NCT05521698RecruitingPhase 1
Bicalutamide for early-stage bladder cancer
This trial tests whether the drug bicalutamide can help men with early-stage (non-invasive) bladder cancer, which has not grown into the bladder muscle. It is given before surgery to see if it can reduce the chance of the cancer coming back. Participants will be randomly assigned to receive bicalutamide or a placebo before their scheduled surgery.
Tucson, ArizonaAges 18 years+ - NCT05541016RecruitingPhase 2
Personalized lower-dose radiation for HPV-related throat cancer
This Phase 2 study tests whether giving a less intense (de-escalated) radiation plan can work for certain people with HPV-related oropharyngeal throat cancer. It uses HPV blood testing and scans to help guide treatment, aiming to keep cancer control while reducing treatment side effects.
Scottsdale, ArizonaAges 18 years+ - NCT05526417Recruiting
Prehab program before treatment for deep leg soft tissue cancer
This trial tests an individualized “prehab” program (exercises and preparation before treatment) to improve recovery and surgical outcomes for adults with deep soft tissue sarcoma in the leg. It’s meant to help your body be as ready as possible for radiotherapy and surgery.
Scottsdale, ArizonaAges 18 years+ - NCT05519878Recruiting
Light plus job therapy for fatigue in genitourinary cancer
This trial tests whether light therapy and an occupational therapy fatigue program can reduce fatigue in people with certain urinary-system cancers who still have mild fatigue during treatment. It may help you feel more energized and manage day-to-day activity while cancer treatment is ongoing.
