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."
