San Francisco, CaliforniaAges 40–75 - NCT04735172Recruiting
Brain scan to compare Parkinson chemical signals in early patients
This study uses a special 7‑Tesla MRI brain scan to measure tiny chemical (metabolite) differences in specific deep brain areas. It compares newly diagnosed, early-stage Parkinson’s patients who are not on Parkinson medication with healthy volunteers.
Clermont-FerrandAges 18–75 - NCT04739072Recruiting
Check colorectal cancer blood tests after curative treatment
This study measures “minimal residual disease,” meaning tiny amounts of cancer that may remain after surgery, using blood samples. It may help doctors better detect who is at higher risk of cancer coming back and guide follow-up care.
Gilbert, ArizonaAges 18 years+ - NCT04745221Recruiting
Fecal microbes therapy to help prevent graft-versus-host disease
This trial studies a treatment made from donor gut microbes to help prevent a common complication after a transplant called acute graft-versus-host disease (aGVHD). It may help by improving the balance and variety of gut bacteria during recovery after haploidentical transplant.
Suzhou, JiangsuAges 18–60 - NCT04721652Recruiting
Track drinking and recovery after hemodialysis sessions
This study looks at how fluid intake after each hemodialysis treatment affects your health. It may help find safer, easier guidance on how much to drink between treatments.
London, OntarioAges 18 years+ - NCT04738422Enrolling by invitationPhase 2
Measuring airway acidity using exhaled air breath tests
This trial studies how “airway pH” (how acidic your breathing tubes are) changes after you drink or inhale an alkaline buffer, using special breath measurements. It may help researchers better understand and measure airway inflammation in people with lung conditions or in healthy non-smokers.
Indianapolis, IndianaAges 18–60 - NCT04700657Recruiting
Study dryness patterns in eye graft-vs-host disease
This study looks at how common and how severe corneal nerve-related dryness is in people with chronic graft-vs-host disease (GVHD) after a stem cell transplant. It may help doctors understand which eye problems are most typical and how best to recognize them early.
Indianapolis, IndianaAges 18 years+ - NCT04742634RecruitingPhase 1/Phase 2
Preemptive drug DEC-C after transplant to reduce hidden cancer
This trial tests whether giving DEC-C (a decitabine-based treatment) soon after an allogeneic transplant can improve outcomes for MDS patients who still have “measurable residual disease” (hidden leftover disease) detectable by a genetic test. It also compares this approach to standard observation if the hidden disease is not detected or if the higher-risk safety checks are not met.
St Louis, MissouriAges 18–75 - NCT04700579Recruiting
Study lung changes before and after treatment for active TB
This study looks at changes in the lungs and immune system before TB treatment and again after treatment. By sampling lung fluid and comparing it over time, researchers hope to learn signatures that reflect how TB responds to care.
