A Study of Tagraxofusp in Combination With Venetoclax and Azacitidine in Adults With Untreated CD123+ Acute Myeloid Leukemia Who Cannot Undergo Intensive Chemotherapy
Recruiting
This study will be divided into 2 parts (Part 1 and Part 2). Part 1 will evaluate 2 doses of tagraxofusp (9 and 12 micrograms/kilogram/day \[μg/kg/day\]), used in combination with venetoclax and azacitidine, to determine the dose for Part 2. This determined dose, in combination with venetoclax and azacitidine, will then be further evaluated in Part 2 in 2 cohorts (TP53 mutated and TP53 wild type). Both parts will be conducted in participants with previously untreated CD123+ AML who are ineligibl... Read More

Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess the safety of venetoclax in combination with obinutuzumab or acalabrutinib in the treatment of CLL. Adverse events and change in disease activity will be assessed. Venetoclax in combination with obinutuzumab or acalabrutinib is being investigated in the treatment of CLL. Study doctors put the participants in 1 of 4 groups, called treatment arms. Participants will receiv... Read More

A Study to Investigate the Safety and Effectiveness of a Coagulation Factor IX Gene Insertion Therapy (REGV131-LNP1265) in Pediatric, Adolescent and Adult Participants With Hemophilia B
Recruiting
Participants in this study have a genetic mutation, specifically in the coagulation (blood clotting) Factor 9 gene that causes severe or moderately severe hemophilia B. This study is researching an experimental gene insertion therapy (the adding of a gene into your DNA) called REGV131-LNP1265, also called the "study drug". Gene insertion therapy aims to teach the body how to produce clotting factor long-term, without the need for factor replacement therapy. The main aim of this study is to find... Read More

Testing the Addition of the Anti-cancer Drug Venetoclax and/or the Anti-cancer Immunotherapy Blinatumomab to the Usual Chemotherapy Treatment for Infants With Newly Diagnosed KMT2A-rearranged or KMT2A-non-rearranged Leukemia
Recruiting
This phase II trial tests the addition of venetoclax and/or blinatumomab to usual chemotherapy for treating infants with newly diagnosed acute lymphoblastic leukemia (ALL) with a KMT2A gene rearrangement (KMT2A-rearranged \[R\]) or without a KMT2A gene rearrangement (KMT2A-germline \[G\]). Venetoclax is in a class of medications called B-cell lymphoma-2 (Bcl-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Blinatumomab is a monoc... Read More

A Study to Assess Efficacy and Safety of Pembrolizumab With or Without Sacituzumab Tirumotecan (MK- 2870) in Adult Participants With Resectable Non Small Cell Lung Cancer (NSCLC) Not Achieving Pathological Complete Response (pCR) (MK-2870-019)
Recruiting
This study will assess if adding sacituzumab tirumotecan with pembrolizumab after surgery is effective in treating NSCLC for participants not achieving pathological complete response. The primary hypothesis of this study is sacituzumab tirumotecan plus pembrolizumab is superior to pembrolizumab monotherapy with respect to disease free survival (DFS) as assessed by blinded independent central review (BICR).

Testing the Combination of an Anti-cancer Drug, Iadademstat, With Other Anti-cancer Drugs (Atezolizumab or Durvalumab) at Improving Outcomes for Small Cell Lung Cancer
Recruiting
This phase I/II trial tests the safety, side effects, and best dose of iadademstat when given together with atezolizumab or durvalumab, and studies the effect of the combination in treating patients with small cell lung cancer that has spread outside of the lung in which it began or to other parts of the body (extensive stage) who initially received standard of care chemotherapy and immunotherapy. Iadademstat may stop the growth of tumor cells by blocking some of the enzymes needed for cell grow... Read More
