Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the overall response rate (ORR) of JHL1101 in combination with CHOP and rituximab (MabThera) in combination with CHOP after 6 cycles of treatment in patients with previously untreated DLBCL.;Primary end point(s): Primary efficacy endpoint: Overall response rate (ORR) after 6 cycles treatment, which is the percentage of CR + PR. The evaluation is according to the International Working Group’s Lugano criteria (based on 5- point scale).;Secondary Objective: 1. To compare the safety of the two treatment groups among the patients with DLBCL. 2. To compare the complete response rate (CR) after 6 cycles of treatment, 1-year progression-free survival rate, 1-year event-free survival rate, and 1-year overall survival rate of the two groups. 3. To compare the immunogenicity of JHL1101 and rituximab (MabThera) in patients with DLBCL 4. To analyze the population pharmacokinetic characteristics of JHL1101 and rituximab (MabThera) in patients with DLBCL and the pharmacokinetic characteristics of patients who experienced infusionrelated reactions. 5. To analyze the pharmacodynamics of B-cell depletion in the two treatment groups among the patients with DLBCL.;Timepoint(s) of evaluation of this end point: after 6 cycles treatment | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary efficacy endpoint: 1. Complete response rate (CR) after 6 cycles treatment: the complete response rate. 2. 1-year progression-free survival (PFS) rate: the proportion of subjects who did not experience disease progression or death from any cause one year after randomization. 3. 1-year event free survival (EFS) rate: the proportion of subjects who did not experience disease progression or who stop receiving treatment for any reasons (such as disease progression, toxicity, patient’s willingness, initiation of new treatment in the absence of clear progression, or death) one year after randomization. 4. 1-year overall survival (OS) rate: the proportion of subjects who did not die from any cause one year after randomization. Safety: Safety and tolerability will be evaluated using the following key safety parameters: 1. Incidence of all adverse events (AEs), treatment-emergent adverse events (TEAEs), adverse events of special interest, and serious adverse events (SAEs) of J-CHOP as compared to R-CHOP, and their severity and correlation with the investigational drug. 2. Changes in vital signs, physical examination findings, and laboratory results before, during, and after study treatment. ADA Analysis: Perform immunogenicity testing on all subjects: Serum samples that are positive for anti-drug antibodies (ADAs) after drug administration will be tested continuously for the presence of neutralizing antibodies (NAbs). The time points for collection of immunogenicity blood samples are: within one hour before the administration of monoclonal antibody on Day 1 of Cycle 1, 2 and Cycle 3, D21 ± 3 days of Cycle 6 (or the date of early withdrawal from the study), 12 weeks ± 3 days after the last drug administration, and 1 year after randomization. 4 mL of venous blood will be collected each time. Population PK Analysis Population pharmacokinetics: PK samples will be collected from all patients. During Cycle 1, samples will | — |
