Apatinib in Patients with Relapsed or Refractory Diffuse Large B Cell Lymphoma: A Phase II, Open-Label, Single-Arm, Prospective Study.
Abstract | PURPOSE: PATIENTS AND METHODS: In this phase II, open-label, single-arm, prospective study, we enrolled patients aged 14-70 years with treatment failure of at least two chemotherapeutic regimens using Simon's two-stage design. All patients were administered apatinib at an initial dose of 500 mg on a 4-week cycle at home and visited the outpatient clinic every two cycles to evaluate efficacy and to record adverse events. We considered objective response rate (ORR) as the primary end point, and progression-free survival (PFS), and overall survival (OS) plus duration of response (DoR) as the secondary end point. (This trial was registered at ClinicalTrials.gov, identifier: NCT03376958.). RESULTS: From January 2017 to February 2019, we screened 35 patients and enrolled 32 eligible patients. At the cutoff point (April 2019), we noted 2 (6.3%) complete responses, 12 (37.5%) partial responses, and 9 (28.1%) stable diseases, attributing to an ORR of 43.8% and a disease control rate of 71.9%. The median PFS and OS were 6.9 (95% confidence interval [CI], 5.8-7.9) and 7.9 months (95% CI, 7.0-8.7), respectively. The median DoR was 5.0 months (95% CI, 3.5-6.5) for patients who achieved PR. The most common grade 3-4 adverse events (AE) were hypertension (12.6%), hand-foot syndrome (9.4%), and leucopenia (6.3%). No apatinib-related deaths were noted. CONCLUSION: Home administration of apatinib shows promising efficacy and manageable AEs in patients with RR DLBCL.
