- Interventions
- Registration Number
- NCT05950165
- Lead Sponsor
- Cho Pharma Inc.
- 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.

- Primary Outcome Measures
Name Time Method Number of subjects with adverse events (AE) 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 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 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 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.
- Secondary Outcome Measures
Name Time Method Clinical benefit rate Through study completion, approximately 16 months The clinical benefit rate (CBR) is the proportion of subjects who achieve CR, PR, and durable SD (SD ≥12 weeks) based on the Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
Serum concentration of CHO-HO1 Through study completion, approximately 16 months To characterize the PK of CHO-H01.
Progression-free survival Through study completion, approximately 16 months Progression-free survival (PFS) is the time from the date of first study dose to disease progression or death whichever occurs first in subjects, evaluated using Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
Serum Antidrug antibody (ADA) concentration Through study completion, approximately 16 months To investigate the immunogenicity of CHO-H01 alone and in combination with lenalidomide, using a validated bridging ADA assay.
Overall survival Through study completion, approximately 16 months The overall survival (OS) is the time from the date of the first study dose to the date of death (any cause), evaluated using Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
Duration of response Through study completion, approximately 16 months Duration of response for responders (CR or PR) is the time interval between the date of the earliest qualifying response and the date of disease progression or death for any cause, whichever occurs earlier; based on the Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
Time to event endpoints of time to progression (TTP) Through study completion, approximately 16 months Time to progression is the time from the date of first study dose to disease progression, evaluated using Modified (not using PET imaging)Lugano Revised Criteria for Response assessment.
Duration of stable disease Through study completion, approximately 16 months Duration of SD defined as the time interval, in the absence of either CR or PR, will be calculated between the date of the first CHO-H01 administration and the date of disease progression or death for any cause, whichever occurs earlier; based on the Modified (not using PET imaging) Lugano Revised Criteria for Response assessment.
