Genentech—the maker of Avastin—appears to have resolved a dispute with ophthalmologists that will allow Avastin to continue to be used to treat eye diseases, both sides announced on Thursday. Genentech angered many eye doctors in October when it announced a change in the distribution of Avastin that would have made it difficult for the doctors to use the drug. The doctors accused the company of trying to force them to use a much more expensive Genentech drug, Lucentis, instead. Lucentis is approved to treat macular degeneration; a disorder that affects the macula—the central part of the retina—causing decreased vision and possible loss of central vision. Macula degeneration is a leading cause of blindness among the elderly. But each injection costs about $2,000 and injections are needed as often as once a month.
Many ophthalmologists are instead resorting to off-label use of Avastin, which is approved only to treat cancer but works in the same way as Lucentis. Doctors are free to prescribe Food and Drug Administration (FDA)-approved medications as they see fit, including off-label. It is off-label marketing of FDA-approved medication—marketing for uses not approved by the FDA—which is illegal. The eye doctors have been relying on compounding pharmacies to divide a vial of Avastin meant for cancer treatment into tiny portions for use in the eye under sterile conditions. In these small doses, Avastin costs $20 to $100 per injection. But Genentech said in October that it would no longer sell Avastin to compounding pharmacies, which specialize in the mixing of medications.
