Rituximab-abbs (Truxima, Teva and Celltrion), the first biosimilar to rituximab (Rituxan), is now available in the United States, according to a press release.

Rituximab-abbs is currently indicated for use in the treatment of adult patients with non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL).

Previously, the FDA approved rituximab-abbs injection in May 2019 based on a review of a comprehensive data package inclusive of foundational and extensive analytical characterization, preclinical data, clinical pharmacology, immunogenicity, clinical efficacy, and safety data.

According to the release, the list price of rituximab-abbs will be 10% lower than the reference product, available through primary wholesalers at $845.55 for a 100-mg vial and $422.75 for a 500-mg vial. However, actual costs to individual patients and providers are expected to be lower, according to the release.

In NHL, rituximab-abbs is indicated for:
  • Relapsed or refractory, low grade or follicular, CD20-positive B-cell NHL as a single agent.
  • Previously untreated follicular, CD20-positive B-cell NHL in combination with first-line chemotherapy and in patients achieving a complete or partial response to a rituximab product in combination with chemotherapy as single-agent maintenance therapy.
  • Non-progressing (including stable disease), low-grade, CD20-positive, B-cell NHL as a single agent after first-line cyclophosphamide, vincristine, and prednisone chemotherapy.
  • Previously untreated diffuse large B-cell, CD20-positive NHL in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone or other anthracycline-based chemotherapy regimens.
In CLL, rituximab-abbs is indicated in combination with fludarabine and cyclophosphamide for adult patients with previously untreated and previously treated CD20-positive CLL.

“We are pleased to announce the launch of the first rituximab biosimilar, Truxima, with our marketing partner Teva in the US,” Hyoung-Ki Kim, vice chairman at Celltrion Healthcare, said in a statement. “We believe that the introduction of Truxima into the US market will contribute to addressing unmet needs of US patients as well.”

Additionally, in light of a patent settlement with Genentech, Teva and Celltrion have a pending FDA submission for rheumatoid arthritis, granulomatosis with polyangiitis, and microscopic polyangiitis for Q2 2020.
