Studies have demonstrated that using follow-on and biosimilar granulocyte colony-stimulating factor (G-CSF) agents can produce cost savings and expand patient access to prophylaxis of febrile neutropenia. Now, a newly published budget impact analysis finds that even greater savings may be possible if patients self-administer these agents at home rather than visiting a provider to receive an injection. 
Teva announced this week that the FDA has approved its tbo-filgrastim (Granix), a follow-on product referencing Neupogen, to reduce the duration of severe neutropenia in patients as young as 1 month old who have nonmyeloid malignancies and are receiving myelosuppressive chemotherapy.
Pfizer announced today that the European Commission (EC) has approved its trastuzumab biosimilar, Trazimera, referencing Herceptin, for marketing. The approval makes Trazimera the fourth trastuzumab biosimilar (following Kanjinti, Ontruzant, and Herzuma) to be approved by the EC, and the first approval of an anticancer biosimilar for Pfizer.
Drug maker Mylan, which in June received FDA approval for its biosimilar pegfilgrastim, Fulphila, confirmed in an email to The Center for Biosimilars® that it has launched the biosimilar in the United States marketplace. Fulphila is the fourth biosimilar—and the first pegfilgrastim biosimilar—to become available to US patients.
The FDA has approved Pfizer's filgrastim-aafi, a filgrastim biosimilar to Amgen's Neupogen. The product, the second filgrastim biosimilar approved in the United States, will be sold under the brand name Nivestym. 
In an email to The Center for Biosimilars®, Mylan confirmed that it will launch its biosimilar pegfilgrastim at a wholesale acquisition cost (WAC) of $4175 per syringe, a price that reflects a 33% discount to the WAC of Amgen’s reference product, Neulasta. 
 
Biosimilars of anticancer monoclonal antibodies are emerging in the therapeutic landscape, and while the body of evidence concerning switching to supportive care biosimilars—epoetin and filgrastim biosimilars—is robust, there are fewer data available concerning a switch to biosimilars of products such as rituximab, trastuzumab, and bevacizumab. 
Intravenous administration of the anti–vascular endothelial growth factor treatment bevacizumab at high doses can result in serious, systemic adverse events (AEs). Additionally, tumors can become resistant to therapy and adopt a more invasive growth pattern. Thus, delivering bevacizumab for the treatment of cancer at a lower dose in a manner that avoids systemic AEs is necessary.
The presence or absence of insurance coverage for trastuzumab treatment was the strongest predictor of trastuzumab therapy use in Chinese patients.
Researchers have reported the development of CubiCAR architecture, which has the potential to improve the safety of chimeric antigen receptor (CAR) T-cell immunotherapies for a broad range of patients with cancer.
