Catherine C. Coombs, MD, presents data investigating venetoclax-based therapy after Bruton tyrosine kinase inhibitors in chronic lymphocytic leukemia.

Jennifer R. Brown, MD, PhD, discusses the clinical implications of the ALPINE study and highlights a subgroup analysis of acquired mutations in patients with chronic lymphocytic leukemia, demonstrating which mutations were associated with resistance to covalent BTK inhibitors.

Treatment with zanubrutinib conferred a PFS benefit vs bendamustine plus rituximab across most biomarker subgroups of patients with treatment-naive chronic lymphocytic leukemia or small lymphocytic lymphoma without del(17p), according to findings from the phase 3 SEQUOIA trial.

Jennifer A Woyach, MD, discusses the efficacy of pirtobrutinib in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who progressed on treatment with a covalent BTK inhibitor, including subgroups with or without previous exposure to a BCL2 inhibitor.

Responses on the non-covalent BTK inhibitor pirtobrutinib remained high in patients with relapsed chronic lymphocytic leukemia who expressed frequent baseline BTK mutations, according to a genomic analysis of the phase 1/2 BRUIN trial.

OncLive® will be LIVE with OncLive® News Network: On Location at the 2023 ASH Annual Meeting. Each day, we will broadcast a series of interviews with top thought leaders, to learn their thoughts and reactions to data presented across oncology during the conference.

Paolo Ghia, MD, PhD, full professor, discusses a biomarker subgroup analysis of the phase 3 SEQUOIA trial investigating zanubrutinib vs bendamustine plus rituximab in patients with treatment-naive chronic lymphocytic leukemia or small lymphocytic lymphoma without 17p deletions.

Ibrutinib plus venetoclax, given at a duration determined by minimal residual disease, improved progression-free survival and overall survival vs fludarabine, cyclophosphamide, and rituximab in patients with treatment-naive chronic lymphocytic leukemia.

Venetoclax-based therapy generated durable responses both overall and in the second or third line following covalent BTK inhibitor discontinuation in real-world patients with chronic lymphocytic leukemia or small lymphocytic lymphoma.

Pirtobrutinib continued to showcase clinically meaningful efficacy in heavily pretreated patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who had prior exposure to a covalent BTK inhibitor.

Zanubrutinib continued to demonstrate improved progression-free survival benefit over ibrutinib in the treatment of patients with relapsed/refractory chronic lymphocytic leukemia and small lymphocytic lymphoma, according to extended follow-up data from the phase 3 ALPINE trial.

The FDA has granted an accelerated approval to pirtobrutinib for the treatment of adult patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who have received at least two prior lines of therapy, including a BTK inhibitor and a BCL2 inhibitor.

John N. Allan, MD, discusses the importance of understanding fixed-duration treatment approaches with BTK inhibitors and BCL2 inhibitors in patients with chronic lymphocytic leukemia, highlighting data within this treatment armamentarium.

Nicole Lamanna, MD, discusses how the use of novel agents could address resistance associated with current treatment options for patients with chronic lymphocytic leukemia.

John N. Allan, MD, discusses current data detailing the activity of venetoclax-based, fixed-duration regimens in the frontline setting for patients with chronic lymphocytic leukemia; the synergy and promising efficacy signals seen with BCL-2 and BTK inhibitor combinations; and ongoing research efforts exploring triplet regimens vs other continuous approaches in this space.

Nicole Lamanna, MD, discusses the challenges of resistance in patients with CLL, highlights treatment being developed for patients who progress on BTK inhibitor– or venetoclax-based regimens, and emphasizes the need for further enrollment onto clinical trials.

Bhagirathbhai Dholaria, MBBS, discusses limitations in the current CLL standards of care that necessitate more effective therapies; BTK inhibitors and degraders on the horizon for this population; and the potential future role of CAR T-cell therapy for patients with CLL.

The FDA has granted priority review to the supplemental biologics license application seeking approval to expand the indication of lisocabtagene maraleucel to include patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who had prior exposure to a BTK inhibitor and a BCL-2 inhibitor.
