Brentuximab Vedotin and Bendamustine Produce Long-Term Clinical Benefit in Patients With Relapsed or Refractory Classical Hodgkin Lymphoma: A Multicenter Real-Life Experience.

ABSTRACT:

Background

Patients with relapsed or refractory classical Hodgkin lymphoma (R/R cHL) have limited opportunities for curative therapy. High-dose therapy followed by autologous stem cell transplantation (HDT-ASCT) produces cure rates of 50% to 60%. Patients relapsing after, or ineligible for HDT-ASCT have limited therapeutic options and long-term remission is uncommon. Furthermore, few patients are candidate to allogeneic stem cell transplantation (AlSCT), a potentially curative approach. The combination of brentuximab vedotin and bendamustine (BVB) is a promising treatment for patients with R/R cHL, regardless of SCT eligibility.

Patients and methods

We conducted a real-life study of BVB in 41 patients with R/R cHL after failure of ≥ 1 therapy including ASCT, AlSCT, or BV.

Results

Among 40 patients evaluable for efficacy, the overall response rate and complete response (CR) rate were 75% and 50%, respectively. No significant differences were observed between patients with primary refractory and relapsed disease, previously treated with ≤ 2 and ≥ 3 lines of therapy, or BV-exposed and BV-naïve. After a median follow-up of 38 months, the median progression free survival (PFS) for the entire population is 26 months; PFS is not reached, 10.5 months, and 4 months for patients achieving CR, partial response and no response, respectively (P < .0001). BVB was well tolerated and no grade 4 toxicity or new safety signals were observed. The most common treatment-emergent adverse events were infections.

Conclusion

Our experience supports the efficacy and tolerability of the BVB combination in R/R cHL as a bridge to SCT, or as a definitive therapy for SCT-ineligible patients. Larger comparative studies testing BVB against standards of care are warranted in both settings.

Project description:BackgroundWe previously demonstrated that brentuximab vedotin (BV) used as second-line therapy in patients with Hodgkin lymphoma is a tolerable and effective bridge to autologous hematopoietic cell transplantation (AHCT). Here, we report the post-AHCT outcomes of patients treated with second-line standard/fixed-dose BV and an additional cohort of patients where positron-emission tomography adapted dose-escalation of second-line BV was utilized.Patients and methodsPatients on the dose-escalation cohort received 1.8 mg/kg of BV intravenously every 3 weeks for two cycles. Patients in complete remission (CR) after two cycles received two additional cycles of BV at 1.8 mg/kg, while patients with stable disease or partial response were escalated to 2.4 mg/kg for two cycles. All patients, regardless of treatment cohort, proceeded directly to AHCT or received additional pre-AHCT therapy at the discretion of the treating physician based on remission status after second-line BV.ResultsOf the 20 patients enrolled to the BV dose-escalation cohort, 8 patients underwent BV dose-escalation. BV escalation was well-tolerated, but no patients who were escalated converted to CR. Of 56 evaluable patients treated across cohorts, the overall response rate (ORR) to second-line BV was 75% with 43% CR. Twenty-eight (50%) patients proceeded directly to AHCT without post-BV chemotherapy, and a total of 50 patients proceeded to AHCT. Thirteen patients received consolidative post-AHCT therapy with either radiation, BV, or a PD-1 inhibitor. After AHCT, the 2-year progression-free survival (PFS) and overall survival were 67% and 93%, respectively. The 2-year PFS among patients in CR at the time of AHCT (n = 37) was 71% compared with 54% in patients not in CR (p = 0.12). The 2-year PFS in patients who proceeded to AHCT directly after receiving BV alone was 77%.ConclusionsSecond-line BV is an effective bridge to AHCT that produces responses of sufficient depth to provide durable remission in conjunction with AHCT (clinicaltrials.gov: NCT01393717).
