ROCKVILLE, Md., Feb. 19, 2019 /PRNewswire/ -- CASI Pharmaceuticals, Inc. (CASI), a U.S. based pharmaceutical company with a platform to develop and accelerate the launch of pharmaceutical products and innovative therapeutics in China, U.S., and throughout the world, today announced that the National Medical Products Administration (NMPA) has approved the Company's Clinical Trial Application (CTA) to allow for a confirmatory clinical trial to evaluate the efficacy and safety of ibritumomab tiuxetan injection (ZEVALIN®). Ibritumomab tiuxetan (ZEVALIN®) is a U.S. Food and Drug Administration (FDA)-approved product indicated for the treatment of patients with relapsed or refractory, low-grade or follicular B-cell non-Hodgkin's lymphoma (NHL) and is currently marketed in the U.S. by Spectrum Pharmaceuticals, Inc. (Spectrum). The Company previously acquired greater China rights to ZEVALIN® from Spectrum and intends to launch ZEVALIN® in China as soon as the confirmatory trial is completed and marketing approval is received from the NMPA.
The Company currently is addressing certain requirements provided by the Center for Drug Evaluation (CDE), a part of the NMPA; upon satisfying those requirements, the Company will start the ZEVALIN® clinical development program in China.
Ibritumomab tiuxetan (ZEVALIN®) is also indicated for the treatment of patients with previously untreated follicular non-Hodgkin's Lymphoma who achieve a partial or complete response to first-line chemotherapy. Ibritumomab tiuxetan (ZEVALIN®) builds on the combined therapeutic effects of a monoclonal antibody directed against the CD20 antigen, augmented with a beta-emitting radioisotope. Rituximab and rituximab biosimilars target the same CD20 antigen.
Wei-Wu He, Ph.D., the Company's Executive Chairman commented, "We are extremely pleased with NMPA's approval to start the confirmatory clinical trial for ZEVALIN® in China. This is another important milestone for CASI as the approval further demonstrates our team's regulatory strength in working with the NMPA and the effective cross-border operations of our teams in the U.S. and China."
