Comparing New Treatments for People With Newly Diagnosed Acute Myeloid Leukemia That Has an IDH2 Gene Change (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial studies how well ASTX727 and venetoclax plus enasidenib works compared to ASTX727 and venetoclax alone for the treatment of older patients with newly diagnosed acute myeloid leukemia (AML) or younger patients who are considered unfit for standard treatment, and who have an abnormal change (mutation) in the IDH2 gene. This gene mutation can cause AML to grow and spread. This trial is being done to see if adding enasidenib to the usual treatment can help mo... Read More

Extension Study of Long-term Safety and Efficacy of Tulisokibart in Participants With Crohn's Disease or Ulcerative Colitis (MK-7240-011)
Recruiting
Researchers want to learn more about tulisokibart (also known as MK-7240) in an extension study. Tulisokibart is a medicine designed to treat active, moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). An extension study is a type of study where people who received tulisokibart in certain other studies for CD or UC (called a parent study) may be able to join this study. The goals of this study are to learn about the safety of tulisokibart over time in people with CD or UC, and i... Read More

A Study of Pembrolizumab (MK-3475) With or Without Intismeran Autogene (V940) in Participants With Non-small Cell Lung Cancer (V940-009/INTerpath-009)
Recruiting
The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).

Testing the Addition of an IDH2 Inhibitor, Enasidenib, to Usual Treatment (Cedazuridine-Decitabine) for Higher-Risk Myelodysplastic Syndrome (MDS) With IDH2 Mutation (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial compares the usual treatment of cedazuridine-decitabine (ASTX727) to the combination treatment of ASTX727 and enasidenib in treating patients with higher-risk, IDH2-mutated myelodysplastic syndrome (MDS). ASTX727 is a combination of two drugs, decitabine and cedazuridine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have... Read More
