摘要
OBJECTIVE:To compare the antitumor efficacy, safety, and pharmacodynamics (PD) characteristics of Hetero-Rituximab (test) with Reference Medicinal Product (Rituximab, Roche) in Non-Hodgkin's Lymphoma (NHL).PATIENTS AND METHODS:Total 40 Follicular Lymphoma (FL) patients were randomized to receive intravenous infusion of either test or reference product. Efficacy (best overall response [BOR] rate [primary end point]), safety, PD (CD19), and immunological assessments (secondary end points) were done at the end of cycle 3 and cycle 6.RESULTS:Out of 40 patients randomized, 17 were in test arm while 23 were in reference arm. At the end of 6 cycles, BOR (complete response [CR] and partial response [PR]) rate was 64.71% (n=11) in Hetero Rituximab compared to the 43.48% (n=10) in reference arm. The difference between test and reference proportions of best overall response rate at cycle 6, lies within the pre-specified limit for noninferiority. Anti-Rituximab antibodies were found to be negative at cycle 3 and cycle 6 for all FL patients. The FL patients who were treated with Hetero Rituximab, showed significant depletion in CD19+ cell which was comparable with Reference drug. Safety and Immunogenic potential of the test drug was comparable to the reference drug in the patients of FL.CONCLUSION:Best overall response rate at Cycle 3, Cycle 6 and end of the study lies within the pre-specified limit for non-inferiority which concludes that test product is therapeutically non-inferior to reference medicinal product.
