Today, Sandoz announced the acceptance by the Food and Drug Administration of its application for a biosimilar rituximab. This biosimilar was approved by the European Medicines Agency in June 2017.
The manufacturer included a phase 3 trial of the agent to treat follicular lymphoma, one of two Hodgkin’s lymphomas for which the originator product is approved to treat. Its pharmacokinetic and pharmacodynamics studies were conducted in patients with rheumatoid arthritis, another major indication.
This marks the second rituximab biosimilar to be submitted to the FDA; Celltrion’s application for its Truxima™ brand was submitted in June. Sandoz’s Zarxio® has been marketed since 2015, and Erelzi® (etanercept-szzs) was approved in August 2016 but is not yet marketed.
In addition, Adello Biologic announced that their 351(k) application for a new biosimilar filgrastim was sent to FDA on September 11. No FDA decision date was announced, but assuming a smooth ride through the process, a decision may be expected around the third quarter of 2018.
This is Adello’s first biosimilar brought to FDA application. According to its website, Adello is currently in clinical trials with a pegfilgrastim biosimilar, with preclinical development on a version of adalimumab.
