A Tale of Two Diseases: Repairing Comparative Effectiveness Research

Writing in the New England Journal of Medicine (Identifying and Eliminating the Roadblocks to Comparative-Effectiveness Research) three authors share their experience in running a head-to-head trial of Avastin (bevacizumab) versus Lucentis (ranibizumab) for wet age-related macular degeneration (AMD). They describe the barriers they faced and suggest that they will need to be removed for comparative effectiveness research –as envisioned under ARRA– to succeed. They make good points and may well be correct in their policy recommendations.

However the case of Avastin and Lucentis is unusual. The products are made by the same manufacturer and are essentially identical. Avastin and Lucentis are marketed separately by Genentech mainly to allow the company to capture a return on investment from its R&D. The issue is that a regular dose of Avastin (e.g., for lung cancer) can be divided up into many doses for the eye. Since the products are sold by volume it turns out that Avastin is cheap when used for wet AMD, even though it’s pricey when used for cancer. As I’ve suggested previously, Genentech should be able to charge Lucentis prices for Avastin when it’s used in the eye. So there are quite a lot of people –starting with the manufacturer itself– who didn’t really want this study to go forward. That’s less likely to be the case with other studies.Continue reading…
