Venetoclax; chronic lymphocytic leukemia; B-cell lymphoma-2 inhibitor
Patients with chronic lymphocytic leukemia with the 17p deletion have a poor prognosis and treatment options are limited. Venetoclax, a novel B-cell lymphoma-2 inhibitor, has been approved for treatment-experienced chronic lymphocytic leukemia patients with the 17p deletion. A phase 1 dose-escalation study to 400mg daily showed overall response rates across all doses of 79% with a complete response achieved in 20%. A phase 2 multicenter open-label study demonstrated overall response rate of 79.4% of patients (95% confidence interval 70.5-86.6) with median duration of follow-up of 12.1 months (IQR 10.1-14.2). Tumor lysis syndrome has been observed during initiation and titration. Assessing risk of tumor lysis syndrome prior to therapy initiation is essential to provide appropriate prophylactic medications. Neutropenia, potentially warranting dose reduction or discontinuation, has been observed. Venetoclax has demonstrated activity in other leukemias, multiple myeloma, and lymphomas. Venetoclax has shown response, and is well tolerated in patients with highly resistant chronic lymphocytic leukemia. It has the potential to be part of the treatment armamentarium for other malignancies.
