文献摘要：
Objective: This multi-center, open-label, randomized, parallel-controlled phase Ⅱ study aimed to compare the pharmacokinetics (PK), pharmacodynamics (PD) and safety profile of ripertamab (SCT400), a recombinant anti-CD20 monoclonal antibody, to rituximab (MabThera?) in patients with CD20-positive B-cell non-Hodgkin lymphoma (NHL). Methods: Patients with CD20-positive B-cell NHL who achieved complete remission or unconfirmed complete remission after standard treatment were randomly assigned at a 1:1 ratio to receive a single dose of ripertamab (375 mg/m2) or rituximab (MabThera?, 375 mg/m2). PK was evaluated using area under the concentration-time curve (AUC) from time 0 to d 85 (AUC0?85 d), AUC from time 0 to week 1 (AUC0?1 w), AUC from time 0 to week 2 (AUC0?2 w), AUC from time 0 to week 3 (AUC0?3 w), AUC from time 0 to week 8 (AUC0?8 w), maximum serum concentration (Cmax), terminal half-life (T1/2), time to maximum serum concentration (Tmax) and clearance (CL). Bioequivalence was confirmed if the 90％ confidence interval (90％ CI) of the geometric mean ratio of ripertamab/rituximab was within the pre-defined bioequivalence range of 80.0％?125.0％. PD, immunogenicity, and safety were also evaluated. Results: From December 30, 2014 to November 24, 2015, a total of 84 patients were randomized (ripertamab, n=42; rituximab, n=42) and the PK analysis was performed on 76 patients (ripertamab, n=38; rituximab, n=38). The geometric mean ratios of ripertamab/rituximab for AUC0?85 d, AUC0?inf, and Cmax were 96.1％ (90％ CI:87.6％?105.5％), 95.9％ (90％ CI: 86.5％?106.4％) and 97.4％ (90％ CI: 91.6％?103.6％), respectively. All PK parameters met the pre-defined bioequivalence range of 80.0％?125.0％. For PD and safety evaluation, there was no statistical difference in peripheral CD19-positive B-cell counts and CD20-positive B-cell counts at each visit, and no difference in the incidence of anti-drug antibodies was observed between the two groups. The incidences of treatment-emergent adverse events and treatment-related adverse events were also comparable between the two groups.Conclusions: In this study, the PK, PD, immunogenicity, and safety profile of ripertamab (SCT400) were similar to rituximab (MabThera?) in Chinese patients with CD20-positive B-cell NHL.
