Study of Chiauranib in Relapsed/Refractory Non-Hodgkin's Lymphoma

Efficacy and Safety of Chiauranib in Relapsed/Refractory Non-Hodgkin's Lymphoma: a Single-arm, Open-label, Multi-site, Exploratory Phase Ib Study

Chiauranib may stop the growth of tumor cells by blocking Aurora kinase B（Aurora B）、VEGFR/PDGFR/c-Kit、CSF-1R targets.

This clinical trial is studying the efficacy and safety of chiauranib works in treating patients with relapsed or refractory non-Hodgkin's lymphoma, in the meantime, exploring the latent biomarkers accompany with chiauranib, as well as the relevancy of which and clinical benefit.

Inclusion Criteria:
