Treating Prostate Cancer That Has Come Back After Surgery With Apalutamide and Targeted Radiation Based on PET Imaging
Recruiting
This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen \[PSA\] after surgical removal of the pr...

Open-Label Study of mRNA-3927 in Participants With Propionic Acidemia
Recruiting
This 3-part, Phase 1/2 study is designed to characterize the safety, tolerability, and pharmacological activity (as assessed by biomarker measurements) and to determine the selected dose of mRNA-3927 in participants with genetically confirmed propionic acidemia (PA). After establishing a dose with an acceptable safety and pharmacodynamic (PD) response for participants ≥1 year of age in Part 1, participants will be enrolled in Part 2 (which will serve as the pivotal study) to allow for determinat...

Using Biomarkers to Help Guide Safe Immunotherapy Discontinuation in Patients With Unresectable Stage IIIB-IV Melanoma, The PET-Stop Trial
Recruiting
This phase II trial investigates how well biomarkers on PET/CT imaging drive early discontinuation of anti-PD-1 therapy in patients with stage IIIB-IV melanoma that cannot be removed by surgery (unresectable). Anti-PD-1 therapy has become a standard therapy option for patients with unresectable melanoma. This trial is being done to determine if doctors can safely shorten the use of standard of care anti-PD1 therapy for melanoma by using biomarkers seen on PET/CT imaging and tumor biopsy.

Testing Cabozantinib With or Without Atezolizumab in Patients With Advanced Papillary Kidney Cancer, PAPMET2 Trial
Recruiting
This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread from where it first started (primary site) to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and...

PRIMARY Ancillary Substudy
Recruiting
The PRIMARY trial (NCT05051033), which compares mitral valve repair (MVr) to transcatheter-edge-to-edge-repair (TEER), offers a platform for conducting mechanistic studies to develop early insights into the pathophysiological processes by which mitral valve prolapse (MVP) can impact left ventricular (LV) myocardial structure and function, and, thereby, predispose to arrhythmias and sudden death. Such insights are key to identifying interventions to reduce the long-term sequelae of heart failure... Read More
