New Insights on Treatment of Veterans With CLL From ASH 2025
New Insights on Treatment of Veterans With CLL From ASH 2025
Insights from phase 3 trials presented at the 2025 American Society of Hematology Annual Meeting may expand treatment options for veterans with chronic lymphocytic leukemia (CLL), as discussed by Dr Nicholas Burwick from University of Washington, Seattle.
Dr Burwick begins with the CLL17 trial examining continuous treatment vs fixed-duration therapy in previously untreated patients. The fixed-duration therapy showed noninferior results. Research pertaining to the veterans population in the phase 2 Benefit VA study may offer further insight on these results.
He next discusses the first study comparing the noncovalent BTKi pirtobrutinib to covalent ibrutinib in both treatment-naive patients and those with relapsed/refractory CLL. Pirtobrutinib demonstrated noninferiority in each subgroup.
Pirtobrutinib was compared to bendamustine plus rituximab in the treatment-naive setting in the next study, showing favorable progression-free survival and a notable trend in overall survival. These two trials could lead to use of a noncovalent BTKi as frontline therapy.
Dr Burwick then turns to 6-year follow-up in the SEQUOIA trial, in which zanubrutinib showed sustained superiority over bendamustine and rituximab. He notes that acalabrutinib is currently the preferred BTKi therapy for veterans with CLL.
Finally, he discusses a study examining combination acalabrutinib and venetoclax, to which obinutuzumab was added either early or late. The rate of infections was significantly higher in the early group, an issue of particular concern in the veterans population.

Diffuse Large B-Cell Lymphoma Highlights From ASH 2023
Highlights in diffuse large B-cell lymphoma (DLBCL) from the 2023 American Society of Hematology (ASH) Annual Meeting and Exposition that are particularly relevant to Veterans Health Administration (VHA) patients are reported by Dr Nicholas Burwick of Puget Sound VA Health Care System.
Dr Burwick begins with a large VHA study examining racial disparities in DLBCL outcomes among veterans. Importantly, overall survival was not significantly different across racial groups.
He next covers two studies in the DLBCL frontline setting. The first examines the efficacy of standard-dose R-CHOP; reduced-intensity R-CHOP; and an anthracycline alternative regimen among older patients. Standard-dose R-CHOP yielded superior results in patients aged 70- to 79-years but not for those older than 80 years, a group that merits further study.
The second frontline study focused on the chemotherapy-free regimen mosunetuzumab plus the antibody-drug conjugate polatuzumab vedotin (pola) in patients who are older and unfit for chemotherapy. The combination showed good preliminary efficacy.
Turning to relapsed/refractory patients, Dr Burwick discusses a real-world study examining response rates to tafasitamab in White vs Black/African American patients and non-Hispanic vs Hispanic patients. Differences between the two groups proved minimal.
Finally, he discusses a study of the bispecific antibody glofitamab and pola in heavily pretreated patients that showed promising results in this population.

Chronic Lymphocytic Leukemia Highlights From ASH 2022
Reporting on chronic lymphocytic leukemia (CLL) highlights from the American Society of Hematology meetings, Dr Nicholas Burwick of the Puget Sound Veterans Administration Health Care System discusses studies ranging from first-line treatment to options for relapsed/refractory disease.
Dr Burwick cites a Veterans Health Administration study documenting the increasing movement toward novel agents as frontline treatment in CLL since 2018, and the emerging trend toward use of second-generation Bruton tyrosine kinase (BTK) inhibitors.
Next, he discusses a study examining the frontline combination of ibrutinib and venetoclax, which may help overcome poor prognosis associated with unmutated IGHV CLL.
In another study, the combination of venetoclax and ibrutinib was examined in high-risk patients treated with ibrutinib for 1 year. The results showed the combination deepens responses and even offers the potential for discontinuation of therapy.
Turning to relapsed/refractory disease, Dr Burwick highlights the latest results of pirtobrutinib, which continues to show efficacy among heavily pretreated patients regardless of prior therapy, reason for discontinuation, or mutation status.
Finally, he points to zanubrutinib, which demonstrated superiority to ibrutinib in a long-range study of progression-free survival.
