Dr. Reddy’s Successfully Completes Phase I Study (IV Route) of DRL_TC, a Proposed Biosimilar of Tocilizumab

Dr. Reddy’s Laboratories Ltd. (BSE: 500124, NSE: DRREDDY, NYSE: RDY, NSEIFSC: DRREDDY; hereafter referred to as “Dr. Reddy’s”), a global pharmaceutical company, announced that its tocilizumab biosimilar candidate, DRL_TC, successfully met its primary and secondary endpoints in a Phase I study. This Phase I study used an intravenous (IV) formulation to evaluate the pharmacokinetic equivalence, safety and immunogenicity of Dr. Reddy’s tocilizumab biosimilar candidate in comparison to reference products.

The Phase I study entitled ‘A Phase I, Double Blind, Randomized, Parallel-group, Single dose, Three arm, Comparative Pharmacokinetic and Pharmacodynamic Study of Dr. Reddy’s Tocilizumab (DRL_TC), USA sourced Reference Tocilizumab (Actemra) and EU sourced Reference Tocilizumab (RoActemra) Administered by the Intravenous Route to Normal Healthy Male Volunteers’ met all primary and secondary endpoints. Pharmacokinetic equivalence of DRL_TC to the EU reference medicinal product* and the U.S. reference product** was successfully demonstrated. The clinical trial also confirmed the similarity between DRL_TC and the EU* and U.S.** reference products in terms of pharmacodynamic parameters and found no noteworthy differences in safety and immunogenicity across these three treatment groups.

The successful outcome of this study represents an important milestone in Dr. Reddy’s commitment to make high-quality biosimilar products more accessible and affordable to healthcare providers and patients around the world.

Dr. Reddy’s is developing the proposed tocilizumab biosimilar as both intravenous and subcutaneous formulations.

Dr. Jayanth Sridhar, Global Head of Biologics at Dr. Reddy’s, said: “Tocilizumab is an important anti-rheumatic agent that has a unique place in treating patients with rheumatoid arthritis and other diseases. By developing the formulation in both subcutaneous and intravenous formulations, we aim to reach more patients around the world. With our recent milestones in our proposed biosimilars of tocilizumab and rituximab, our partner’s launch of pegfilgrastim in the U.S and Europe, we look forward to maintaining our momentum as part of our goal to serve over 1.5 billion patients by 2030.”
