About

This is a 2-part study. Part 1/Phase 1 of the study will be conducted to determine the safety and tolerability of CHO-H01 in subjects with relapsed/refractory CD20+ non-Hodgkin's lymphoma. It will also determine maximum tolerated dose (MTD) and recommended phase II dose (RP2D).

Part 2/Phase 2 will assess the anticancer activity and safety of CHO-H01 in subjects with relapsed/refractory CD20+ non-Hodgkin's lymphoma.

Full description

Phase I FIH study includes subjects with relapsed/refractory CD20 + non-Hodgkin's lymphoma, who may benefit from treatment with CHO-H01. In Phase I of the study, the first 2 cohorts will follow a 2-step modified accelerated titration dose escalation design and subsequent cohorts will follow a standard 3+3 dose escalation design.

The investigational medicinal product, CHO-H01, will be administered via IV infusion once weekly for 4 weeks in Cycle 1 and then once only (on Day 1) in each subsequent 21-day cycle until disease progression or for up to 6 cycles (19 weeks) of treatment.

Once the MTD/RP2D has been confirmed, Phase IIa of the study will be initiated. The purpose of Phase IIa is to assess anticancer activity and safety in 2 cohorts of subjects with either aggressive B-cell lymphoma (DLBCL-NOS) or indolent (follicular) B-cell lymphoma, until intolerable toxicity or disease progression, withdrawal, or death occurs.
