Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
Long Beach, CaliforniaAges 18 years+ - NCT04804332Recruiting
Hysteroscopy to remove leftover tissue after miscarriage
This trial studies the best way to remove leftover pregnancy tissue after a first-trimester miscarriage. It compares approaches guided by a camera procedure in the uterus to see which helps most, especially for people who want to get pregnant again soon.
GhentAges 18–39 - NCT04793152Recruiting
Tested vancomycin dosing for serious MRSA using different lab targets
This trial compares two ways of dosing vancomycin (an antibiotic) for serious MRSA infections by using different blood test targets. The goal is to see if the newer approach works at least as well as the standard one, while keeping patients safe.
Hamilton, OntarioAges 18 years+ - NCT04795193Enrolling by invitation
Minithoracotomy vs open surgery for multiple blocked heart arteries
This trial compares two types of bypass surgery for people with multiple blocked heart arteries, to see which one better improves quality of life and how well the bypasses stay open. You may be assigned based on your preferences, and the study also tracks heart scan and follow-up results.
Beijing, Beijing MunicipalityAges 25–85 - NCT04825587Recruiting
Study after first ACL reconstruction in children
This study looks at children’s outcomes after their first ACL ligament surgery using a specific graft (quadriceps tendon). It may help doctors compare and improve how ACL repairs are done in growing kids with open or closing growth plates.
Chicago, IllinoisAges Up to 18 years - NCT04823299Recruiting
Atrial fibrillation ablation using two different energy types
This trial tests whether one ablation approach works better than another for paroxysmal (intermittent) atrial fibrillation by targeting the heart’s “triggers” and “substrate” (where the rhythm problem is). If you qualify, you’ll be randomly assigned to one of two ablation energy methods during a pulmonary vein isolation procedure.
Ottawa, OntarioAges 18 years+ - NCT04731610Recruiting
Radiation after thymoma surgery versus watchful waiting
This trial compares two approaches after complete surgical removal of stage IIb or III thymoma: targeted radiation (conformal post-operative radiotherapy) or no further treatment right away (surveillance). It aims to see whether adding radiation lowers the risk of the cancer coming back without causing unacceptable side effects.
