Jan Joseph Melenhorst, PhD, discusses the evolving understanding of the use of CAR T-cell therapies in the treatment of patients with chronic lymphocytic leukemia.

Patients with chronic lymphocytic leukemia who experience disease progression during treatment with either covalent or noncovalent BTK inhibitors displayed a higher frequency of BTK mutations in L528W as well as RAS/RAF/MAPK pathway alterations, indicating that these alterations may play a role in the development of BTK inhibitor resistance.

Findings from the phase 1/2 BRUIN trial of show a distinct genetic evolution in patients with B-cell malignancies. However, the baseline BTK mutations did not impede pirtobrutinib’s effectiveness.

Patients with relapsed/refractory chronic lymphocytic leukemia achieved sustained progression-free survival and overall survival benefit after treatment with fixed-duration venetoclax plus rituximab vs bendamustine plus rituximab, according to data from the phase 3 MURANO trial.

The undetectable minimal residual disease ate achieved with bendamustine followed by obinutuzumab, acalabrutinib, and venetoclax increased as the regimen was continued as maintenance treatment in patients with relapsed or refractory chronic lymphocytic leukemia.

Patients with chronic lymphoctyic leukemia treated with pirtobrutinib monotherapy experienced comparable objective response rates regardless of acquired BTK mutation and a decrease or clearance of BTK cysteine 481 clones despite the emergence of non-C481 clones or other less common mutations during or near the time of progression.

Mazyar Shadman, MD, MPH, discusses preliminary long-term findings from the evaluation of zanubrutinib in previously treated patients with chronic lymphocytic leukemia or small lymphocytic lymphoma who were intolerant to ibrutinib and/or acalabrutinib.

Stable peripheral disease levels lasting 12 months were reported in patients with treatment-naïve chronic lymphocytic leukemia following 6 years of continuous treatment with ibrutinib.

CURE looks back on some of the most important stories in the chronic lymphocytic leukemia space from 2023.

Patients with chronic lymphocytic leukemia treated with Imbruvica plus Venclexta demonstrated a healthy immune profile over time in addition to reduction in CLL disease burden.
