Hematology Disease Topics & Pathways:
Research, Clinical trials, Combination therapy, Clinical Research, Checkpoint Inhibitor, Treatment Considerations, Biological therapies, Monoclonal Antibody Therapy
Methods: Eligible pts were either >60 yrs or considered unsuitable for standard chemotherapy because of cardiac, pulmonary or renal dysfunction. Pts received BV at 1∙8 mg/kg (dose cap at 180 mg) and nivo at 3 mg/kg both intravenously every 21 days for 8 cycles. The primary endpoint was overall response rate (ORR).
Results: Follow-up data were available for 39 of the original 46 pts. At a median follow-up of 58.5 months (0.45-65.4 mo), the median duration of response was 17.2 mo (11.6-45.2). 58.7% of the patients had progressed with the median progression-free survival of 18.3 mo (12.8-46.3 mo); thus 41.3% had still not experienced a progression event. Median overall survival was not yet reached with 84.8% of patients still alive.
Conclusions: BV-nivo is an effective regimen for patients >60 yr, curing approximately 40% of pts. For those not cured by initial therapy, outcome with subsequent treatment is excellent, suggesting check point inhibitor sensitization, or other factors. Optimization of dose and schedule, and incorporation of other novel agents will result in a successful chemo-free approach for older patients with HL, especially those unable to receive an anthracycline.
