The FDA has approved Mvasi (bevacizumab-awwb) as a biosimilar to Avastin (bevacizumab) for the treatment of multiple types of cancer.
Indications: Mvasi is a vascular endothelial growth factor-specific angiogenesis inhibitor indicated for the treatment of metastatic colorectal cancer (mCRC), non-squamous non-small cell lung cancer (NSCLC), glioblastoma, metastatic renal cell carcinoma (mRCC), and cervical cancer.
Dosage and administration:
- mCRC: 5 mg/kg IV every 2 weeks with bolus-IFL; 10 mg/kg IV every 2 weeks with FOLFOX4; 5 mg/kg IV every 2 weeks or 7.5 mg/kg IV every 3 weeks with fluoropyrimidine-irinotecan or fluoropyrimidine-oxaliplatin based chemotherapy.
- Non-squamous NSCLC: 15 mg/kg IV every 3 weeks with carboplatin/paclitaxel.
- Glioblastoma: 10 mg/kg IV every 2 weeks.
- mRCC: 10 mg/kg IV every 2 weeks with interferon alfa.
- Cervical cancer: 15 mg/kg IV every 3 weeks with paclitaxel/cisplatin or paclitaxel/topotecan.
Efficacy and safety: Approval is based on evidence showing that Mvasi is biosimilar to Avastin.
Side effects/risks: Most common adverse reactions are epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, rectal hemorrhage, lacrimation disorder, back pain, and exfoliative dermatitis.
