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.

Clinical and Genetic Evaluation of Individuals With Undiagnosed Disorders Through the Undiagnosed Diseases Network
Recruiting
Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking the... Read More

Testing the Use of AMG 510 (Sotorasib) and Panitumumab as a Targeted Treatment for KRAS G12C Mutant Solid Tumor Cancers (A ComboMATCH Treatment Trial)
Recruiting
This phase II ComboMATCH treatment trial tests how well AMG 510 (sotorasib) with or without panitumumab works in treating patients with KRAS G12C mutant solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Sotorasib is in a class of medications called KRAS inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells. Pan... Read More

Detecting Pulmonary Hypertension With the Eko CORE 500 Digital Stethoscope
Recruiting
Brief Summary: This prospective, observational study will evaluate whether synchronized heart sound (phonocardiogram, PCG) and three-lead electrocardiogram (ECG) recordings collected with the Eko CORE 500 can help screen for pulmonary hypertension (PH). Adults (≥18 years) undergoing clinically indicated transthoracic echocardiography and/or right heart catheterization (RHC) will complete one study visit (\~20 minutes). During the visit, study staff will obtain at least four 15-second CORE 500 r... Read More

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 Nivolumab Alone or With Cabozantinib to Prevent Mucosal Melanoma Return After Surgery
Recruiting
This phase II trial tests whether nivolumab in combination with cabozantinib works in patients with mucosal melanoma. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. T... Read More
