The market read

The FDA approval of a biosimilar is a positive development for the company, expanding its product portfolio and market presence.

Dr. Reddy's Laboratories Ltd. announced on August 1, 2026, that the U.S. Food and Drug Administration (FDA) has approved its rituximab biosimilar for the U.S. market. This approval is a significant addition to Dr. Reddy's global biosimilars portfolio and strengthens its presence in the United States.

The rituximab biosimilar was developed, manufactured, and submitted for approval by Dr. Reddy's. The approval follows a successful Pre-License Inspection (PLI) by the U.S. FDA at the company's biologics manufacturing facility in Bachupally, Hyderabad. This highlights the company's capabilities in producing complex biologic medicines for highly regulated markets and its commitment to biosimilars.

Under a commercialization agreement, Fresenius Kabi will exclusively market the product in the United States. Sridevi Khambhampaty, Global Head of Biologics at Dr. Reddy's Laboratories, stated that the FDA approval on the target date demonstrates their expertise in developing and manufacturing complex biologic medicines for global markets.

The rituximab biosimilar has already been commercialized in India, the European Union, the United Kingdom, and over 25 emerging markets. It has also received marketing approval in Switzerland and Canada. Rituximab is a monoclonal antibody used to treat various B-cell malignancies, such as non-Hodgkin lymphoma and chronic lymphocytic leukemia, as well as certain autoimmune conditions.

The FDA approval is backed by extensive analytical, non-clinical, and clinical data, confirming the biosimilar's high similarity to the reference product with no clinically significant differences in safety, purity, and potency.
