FDA Holds Up 2 Celltrion Biosimilars

FDA has issued complete response letters for two biosimilars — Truxima, a version of Roche’s Rituxan (rituximab), and Herzuma, a biosimilar of Roche’s Herceptin (tratsuzumab) — to be manufactured for Teva by Celltrion, a Korean pharmaceutical company. Celltrion said it was “committed to working with the regulatory agency to fully resolve all outstanding issues with an aim to receive approval this year.”

FDA issued a 1/26 Warning Letter to Celltrion following an inspection at the firm’s Incheon manufacturing facility that found violations of current good manufacturing practice regulations for finished pharmaceuticals and recommended that the company retain a consultant to assist it in meeting requirements.

BLAs for the two products were submitted 8/2017.
