Overview
Brief Summary
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 2a will assess the anticancer activity and safety of CHO-H01 plus lenalidomide in subjects with low-grade relapsed/refractory CD20+ non-Hodgkin's lymphoma.
Detailed 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 of CHO-H01 plus lenalidomide in low-grade relapsed/refractory CD20 + non Hodgkin's lymphoma, including follicular lymphoma (Grades 1-3a), marginal zone lymphoma, and small lymphocytic lymphoma.

Outcomes
Primary Outcomes
Number of subjects with adverse events (AE)
Time Frame: Through study completion, approximately 16 months
To assess the safety and tolerability of CHO-H01 as a single agent in subjects with relapsed/refractory CD20 + non-Hodgkin's lymphoma and CHO-H01 plus lenalidomide in subjects with low-grade relapsed/refractory CD20 + non-Hodgkin's lymphoma.
Number of subjects with dose-limiting toxicities
Time Frame: Through study completion, approximately 16 months
All AEs and toxicities are evaluated based on the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTCAE) Version 5.0. The 5 general grades are Grade 1: Mild, Grade 2: Moderate, Grade 3: Severe, Grade 4: Life-threatening or disabling, and Grade 5: Death (outcome of AE).
Objective Response Rate
Time Frame: Through study completion, approximately 16 months
Objective response rate (ORR) is the proportion of subjects with a best overall response of complete response (CR) or partial response (PR). ORR will be measured based on Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
Best overall response
Time Frame: Through study completion, approximately 16 months
The best overall response (CR, PR, stable disease \[SD\], or progressive disease \[PD\]) is defined as the best response across all time points.
