Improved outcome of patients with relapsed/refractory Hodgkin lymphoma with a new fotemustine-based high-dose chemotherapy regimen.

ABSTRACT: High-dose chemotherapy (HDT) with autologous stem cell transplantation is the standard of care for relapsed/refractory (RR) Hodgkin lymphoma (HL). Given that HDT may cure a sizeable proportion of patients refractory to first salvage, development of newer conditioning regimens remains a priority. We present the results of a novel HDT regimen in which carmustine was substituted by a third-generation chloroethylnitrosourea, fotemustine, with improved pharmacokinetics and safety (FEAM; fotemustine, etoposide, cytarabine, melphalan) in 122 patients with RR-HL accrued into a prospective registry-based study. Application of FEAM resulted in a 2-year progression-free survival (PFS) of 73·8% [95% confidence interval (CI), 0·64-0·81] with median PFS, overall survival and time to progression yet to be reached. The 2-year risk of progression adjusted for the competitive risk of death was 19·4% (95% CI, 0·12-0·27) for the entire patient population. Most previously established independent risk factors, except for fluorodeoxyglucose ((18) (F) FDG)-uptake, were unable to predict for disease progression and survival after FEAM. Although 32% of patients had (18) (F) FDG-positrin emission tomography-positive lesions before HDT, the 2-year risk of progression adjusted for competitive risk of death was 19·4% (95% CI; 0·12-0·27). No unusual acute toxicities or early/late pulmonary adverse events were registered. FEAM emerges as an ideal HDT regimen for RR-HL patients typically pre-exposed to lung-damaging treatments.

Project description:Programmed death-1 (PD-1) blockade monotherapy induced durable remission in a subset of patients with relapsed/refractory classical Hodgkin lymphoma (cHL). We asked whether the anti-PD-1 agent, camrelizumab, combined with the DNA demethylating agent, decitabine, improves progression-free survival (PFS) in patients with relapsed/refractory cHL over camrelizumab alone. This extended follow-up of an ongoing randomized phase II trial analyzed PFS among patients enrolled from January 2017 through July 2018. Sixty-one patients with relapsed/refractory cHL who were clinically naïve to PD-1 blockade and had received ≥2 previous therapies were randomized 1:2 to receive either camrelizumab (200 mg) monotherapy or camrelizumab (200 mg, day 8) combined with decitabine (10 mg/day, days 1-5) every 3 weeks. With a median follow-up of 34.5 months, complete remission was 79% (95% CI 63% to 90%) in the decitabine-plus-camrelizumab group versus 32% (95% CI 13% to 57%) in the camrelizumab group (p=0.001). Median duration of response was not reached in the decitabine-plus-camrelizumab group, with an estimated 63% (95% CI 46% to 75%) of patients maintaining a response at 24 months. Median PFS with decitabine-plus-camrelizumab therapy was 35.0 months (95% CI not reached) and 15.5 months (95% CI 8.4 to 22.7 months) with camrelizumab monotherapy (HR, 0.46; 95% CI 0.21 to 1.01; p=0.02). Female gender, lower tumor burden, and fewer previous therapies were favorable prognostic factors for durable remission with camrelizumab monotherapy. The PFS benefits of decitabine-plus-camrelizumab versus camrelizumab were observed in most subgroups, especially in patients with relative larger tumor burdens and those treated with ≥3 prior therapies. After decitabine-plus-camrelizumab treatment, the percentage increase of circulating peripheral central memory T-cells correlated with both improved clinical response and PFS, suggesting a putative biomarker of decitabine-plus-camrelizumab therapy for cHL. Decitabine-plus-camrelizumab results in longer PFS compared with camrelizumab alone in patients with relapsed/refractory cHL. NCT02961101 and NCT03250962.
