Official title
Prospective Randomized Phase II Study of Acalabrutinib + Obinutuzumab or Venetoclax in Previously Untreated CLL
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial tests whether acalabrutinib in combination with venetoclax or obinutuzumab works to shrink tumors in patients with treatment-naive chronic lymphocytic leukemia . Acalabrutinib is also an inhibitor that works in the body to block the activation of certain cells that lead to the growth of cancerous B cells. 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. Obinutuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving acalabrutinib in combination with venetoclax or obinutuzumab may help ease symptoms, decrease the amount of cancer suggestive of improvement, prolonged disease-free remission and/or survival, and increased knowledge about cancer treatment in patients with chronic lymphocytic leukemia. Patients will be treated with acalabrutinib for 12 cycles, and then randomized to receive 6 cycles of acalabrutinib plus obinutuzumab or acalabrutinib plus venetoclax.
