Bevacizumab is a recombinant humanized monoclonal antibody that inhibits vascular endothelial growth factor (VEGF), used mainly in oncology as part of combination chemotherapy regimens.
Bevacizumab is a recombinant humanized monoclonal antibody that inhibits vascular endothelial growth factor (VEGF), used mainly in oncology as part of combination chemotherapy regimens. Its evidence-based indications, by strength of evidence, are:
Intravitreal (into-the-eye) Bevacizumab is widely used off-label around the world, including in Bangladesh, as a compounded/repackaged preparation for wet age-related macular degeneration, diabetic macular edema, retinal vein occlusion, and neovascular glaucoma, because it is markedly less expensive than agents formally approved for intraocular use. This ophthalmic use is not FDA-approved and requires careful aseptic repackaging by a qualified compounding facility; it should only be given under the direct supervision of an ophthalmologist experienced in intravitreal injection.
Any use of Bevacizumab must be individualized and supervised by a qualified oncologist or ophthalmologist, as appropriate to the indication.
Dosage of Bevacizumab is highly indication-specific and must always be prescribed and administered by a qualified oncologist (for systemic use) or ophthalmologist (for compounded intravitreal use). The table below summarizes commonly used regimens; actual dosing must follow the specific protocol chosen by the treating physician.
| Indication | Typical adult dose |
|---|---|
| Metastatic colorectal cancer | 5 mg/kg IV every 2 weeks (with bolus-IFL) or 10 mg/kg IV every 2 weeks (with FOLFOX4); second-line: 5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks |
| Non-squamous NSCLC | 15 mg/kg IV every 3 weeks, with carboplatin and paclitaxel |
| Recurrent glioblastoma | 10 mg/kg IV every 2 weeks (single agent) |
| Metastatic renal cell carcinoma | 10 mg/kg IV every 2 weeks, with interferon alfa |
| Cervical cancer | 15 mg/kg IV every 3 weeks, with paclitaxel and cisplatin, or paclitaxel and topotecan |
| Ovarian/fallopian tube/peritoneal cancer | 10-15 mg/kg IV every 2-3 weeks depending on regimen and disease setting |
| Hepatocellular carcinoma | 15 mg/kg IV every 3 weeks, after atezolizumab, on the same day |
| Ophthalmic (off-label, compounded) | A micro-dose (typically ~1.25 mg in 0.05 mL) by intravitreal injection, administered only by an ophthalmologist; frequency per treatment protocol |
The first infusion is given over 90 minutes; if well tolerated, subsequent infusions may be shortened to 60 minutes, then 30 minutes, under close monitoring. Treatment should continue until disease progression or unacceptable toxicity, unless a fixed-duration regimen is specified.
Withhold Bevacizumab for at least 28 days before and after elective major surgery due to wound-healing risk (see Precautions and Warnings).
Bevacizumab carries serious, potentially fatal risks alongside common, generally manageable side effects. These differ substantially between systemic (intravenous, oncology) use and off-label ophthalmic (intravitreal) use.
Hypertension, proteinuria, fatigue/asthenia, diarrhea, abdominal pain, headache, decreased appetite, stomatitis, epistaxis (nosebleeds), altered taste, dry skin, rash, and low white blood cell counts.
Eye pain or irritation, transient increase in intraocular pressure, floaters, conjunctival hemorrhage, and rare but serious risks including endophthalmitis (intraocular infection), retinal detachment, and intraocular inflammation.
Report any severe abdominal pain, unusual bleeding, chest pain, sudden severe headache, vision changes, or signs of infection to a physician immediately.
Bevacizumab is contraindicated in patients with known severe hypersensitivity to Bevacizumab or to any component of the formulation, including hypersensitivity reactions to Chinese hamster ovary (CHO) cell products or other recombinant human or humanized antibodies.
No other absolute contraindications are established in the approved labeling; conditions such as recent surgery, active bleeding, uncontrolled hypertension, or pregnancy represent important precautions/relative contraindications requiring careful risk-benefit assessment rather than true absolute contraindications, and are discussed under Precautions and Warnings and Pregnancy and Lactation.
