The Food and Drug Administration has approved a biosimilar to bevacizumab (Avastin) for the treatment of certain colorectal, lung, brain, kidney, and cervical cancers.
Bevacizumab-awwb is the first biosimilar approved in the United States for the treatment of cancer, the FDA said in a press release.
Approval is based on structural and functional characterization, animal study data, human pharmacokinetic and pharmacodynamics data, clinical immunogenicity data, and other clinical safety and effectiveness data that demonstrate bevacizumab-awwb is biosimilar to bevacizumab, the FDA said.
Approved indications include:• Metastatic colorectal cancer, in combination with intravenous 5-fluorouracil-based chemotherapy for first- or second-line treatment.
• Metastatic colorectal cancer, in combination with fluoropyrimidine-irinotecan–based or fluoropyrimidine-oxaliplatin–based chemotherapy for the second-line treatment of patients who have progressed on a first-line bevacizumab product–containing regimen.
• Non-squamous non–small cell lung cancer, in combination with carboplatin and paclitaxel for first line treatment of unresectable, locally advanced, recurrent, or metastatic disease.
• Glioblastoma with progressive disease following prior therapy, based on improvement in objective response rate.
• Metastatic renal cell carcinoma, in combination with interferon alfa.
• Cervical cancer that is persistent, recurrent, or metastatic, in combination with paclitaxel and cisplatin or paclitaxel and topotecan.
Common expected side effects of the biosimilar include epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, hemorrhage, lacrimation disorder, back pain, and exfoliative dermatitis.
Serious expected side effects include perforation or fistula, arterial and venous thromboembolic events, hypertension, posterior reversible encephalopathy syndrome, proteinuria, infusion-related reactions, and ovarian failure. Women who are pregnant should not take bevacizumab-awwb.
The biosimilar to bevacizumab carries a similar boxed warning regarding the increased risk of gastrointestinal perforations; surgery and wound healing complications; and severe or fatal pulmonary, gastrointestinal, central nervous system, and vaginal hemorrhage.
The biosimilar approval was granted to Amgen, which will market the drug under the trade name Mvasi.
