A Study to Assess Adverse Events and Change in Disease Activity When Intravenous (IV) Pivekimab Sunirine is Given in Combination With Oral Venetoclax and IV or Subcutaneous Azacitidine in Adult Participants With Acute Myeloid Leukemia (AML)

Официальное название

A Randomized Phase 2/3 Study Evaluating the Safety and Efficacy of Pivekimab Sunirine (PVEK) in Combination With Venetoclax and Azacitidine in Adult Subjects With Newly Diagnosed Acute Myeloid Leukemia (AML) Ineligible to Receive Intensive Chemotherapy

Обзор

Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably. Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow (the spongy tissue inside the bones) that affects white blood cells that helps to fight infections and also prevents normal blood cell production. This study will assess the adverse events and changes in the disease activity when Pivekimab Sunirine (PVEK) is given in combination with Venetoclax (VEN) and Azacitidene (AZA) in adult participants with AML ineligible to receive intensive chemotherapy. Pivekimab sunirine is a drug being evaluated in the treatment of AML.This is a Phase 2/Phase 3, study of PVEK. Phase 2 is open-label and randomized. Phase 3 is double-blind, randomized. Phase 2 and Phase 3 studies test potential new treatments in patients with a condition or disease. Open-label means that both patients and study doctors know which study treatment is given to patients in Phase 2 of the study. Double-blind means that neither the patients nor the study doctors know who is given which study treatment in Phase 3 of the study. Approximately 660 adult participants will be enrolled in 180 sites worldwide. In Phase 2 of the study, patients will be randomized to receive PVEK + VEN + AZA or standard of care treatment with VEN + AZA. In Phase 3, patients will be randomized to receive PVEK + VEN + AZA or a matching-placebo for PVEK plus VEN + AZA. PVEK is given as an infusion into the vein, AZA is given as an injection under your skin (subcutaneous) or as an infusion into the vein (intravenous) (depending on country where patient enrolls), and VEN is a tablet given by mouth. The total study duration is approximately 71 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, and checking for side effects.
