8034 Background: Sintilimab, a programmed death-1 checkpoint inhibitor, has demonstrated efficacy in relapsed/refractory cHL after the primary analysis of the ORIENT-1 study. Here, we report the updated safety and efficacy profile after long-term follow-up. Methods: ORIENT-1 is a multicenter, single-arm, phase II study in China. Classical Hodgkin’s lymphoma patients who had failed ≥2 lines of systemic therapy, including autologous hematopoietic stem cell transplantation (HSCT) were enrolled. Sintilimab, 200 mg IV was given every 3 weeks, until disease progression, death, unacceptable toxicity, or withdrawal from study. The primary endpoint objective response rate (ORR) by an independent radiological review committee (IRRC) per IWG 2007 has been reported before. The progression free survival (PFS) by IRRC follow-up data are reported herein. Results: 96 patients were treated. As of the data cutoff on 30 Sep, 2019, 57.3 % patients complete two-year treatment, with a median follow-up of 26.7 months. The median duration of treatment was 24.1 months (range: 0.7 to 24.8). Of 49 patients with progressive disease (PD) by investigator, 39/49 (79.6%) patients received treatment beyond PD, with a median treatment duration after PD of 8.0 months (range: 1.4 to 20.8). The median PFS was 18.6 months (95%CI: 14.4 to 22.3). Median overall survival has not been reached. Two-year OS rate was 96.3% (95%CI: 88.9% to 98.8%). The treatment-related adverse event (TRAE) was reported in 92/96 (95.8%) patients, most (71/96, 74.0%) of which were grade 1-2. The most common grade 3 or 4 TRAEs were pyrexia (3/96, 3.1%), lipase increased (3/96, 3.1%) and lymphocyte decreased (3/96, 3.1%). Conclusions: The results from long-term follow-up showed that, in addition to a high rate of response, sintilimab also demonstrated durable efficacy and favorable long-term safety profile. Considering the high rate (nearly 80%) of treatment beyond PD, IWG 2007 which was used to evaluate PFS may not be a suitable criteria for evaluating the efficacy of anti-PD-1 antibody in cHL. Further investigation and analysis are required. Clinical trial information: NCT03114683 .

7533 Background: Classical Hodgkin’s lymphoma (cHL) is characterized by chromosome 9p24.1 alterations and PD-1 ligand overexpression. Sintilimab, a programmed death-1 checkpoint inhibitor, has demonstrated efficacy in relapsed/refractory cHL after the primary analysis of the ORIENT-1 study. Here, we report the updated safety and efficacy prolines after extended follow-up. Methods: ORIENT-1 is a multicenter, single-arm, phase II study in China. Classical Hodgkin’s lymphoma patients who had failed ≥2 lines of systemic therapy, including autologous hematopoietic stem cell transplantation (HSCT) were enrolled. Sintilimab, 200 mg IV was given every 3 weeks, until disease progression, death, unacceptable toxicity, or withdrawal from study. The primary endpoint was objective response rate (ORR) assessed by an independent radiological review committee (IRRC) according to 2007 IWG criteria. Results: 96 patients were treated. As of the data cutoff on 16 October, 2018 72.9% of patients were continuing treatment with a median follow-up of 14 months. Median number of treatment cycles was 20 (range: 1 to 26). ORR was 85.4% (82/96, 95%CI: 76.7 to 91.8) based on IRRC review. Twenty-eight patients (29.2%) achieved complete response (CR) by PET scan. At the time of analysis, 59 out of 82 patients who had achieved complete or partial response continued to have an on-going response. The median duration of response (DoR) and progression free survival (PFS) have not been reached. The most common treatment-related adverse event (TRAE) was pyrexia (40.6%, 39/96), 92.3% of which was grade 1 or 2. The most common grade 3 or 4 TRAEs were pyrexia (3.1%) and anemia (3.1%). One death occurred which was not considered treatment related. Conclusions: ORIENT-1 study has the largest cohort of cHL patients in China treated with a PD-1. In addition to a high rate of response, sintilimab also demonstrated durable efficacy and favorable long-term safety profile after extended follow-up. Clinical trial information: NCT03114683.

Long Term Follow Up

As a result of therapeutic advances, there is a growing population of survivors of both Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). A thorough understanding of the late effects of cancer and its treatment, including the risk of developing a second malignancy and non-neoplastic complications, most notably cardiac disease, is essential for the proper long-term follow-up care of these patients. For HL survivors cured in the past 5 decades, a large body of literature describes a range of long-term effects, many of which are related to extent of treatment. These studies form the basis for many of the follow-up recommendations developed for HL survivors. As HL therapy continues to evolve, however, with an emphasis toward treatment reduction, in particular for early-stage disease, it will be important to rigorously observe this new generation of patients long term to document and quantify late effects associated with modern treatments. Although data on late effects after NHL therapy have recently emerged, the formulation of structured follow-up plans for this heterogeneous group of survivors is challenging, given the highly variable natural history, treatments, and overall prognosis. However, the chemotherapy and radiation therapy approaches for some types of NHL are similar to that for HL; thus, some of the follow-up guidelines for patients with HL may also be transferrable to selected survivors of NHL. Additional work focused on treatment-related complications after NHL will facilitate the development of follow-up programs, as well as treatment refinements to minimize late effects in patients with various types of NHL.
