Study Design
We developed a Markov model to capture the total costs and HRQL for patients with newly diagnosed neovascular AMD under 4 treatment options: monthly bevacizumab injections, as-needed bevacizumab injections, monthly ranibizumab injections, and as-needed ranibizumab injections. A societal perspective was taken to encompass all parties affected by the treatment choice: patients, providers, and payers. The model followed a hypothetical cohort of patients aged 80 years (the mean age for neovascular
Base Model
Over 20 years, the expected costs for a single patient with newly diagnosed neovascular AMD receiving monthly bevacizumab, as-needed bevacizumab, monthly ranibizumab, and as-needed ranibizumab were $79 771, $65 267, $257 496, and $163 694, and the QALYs for a patient receiving these treatments were 6.66, 6.60, 6.68, and 6.64, respectively. The ICER of monthly bevacizumab over as-needed bevacizumab was $242 357/QALY. The ICER of monthly ranibizumab over as-needed bevacizumab was
Discussion
As health care policymakers aim to curtail rising health care costs, treatments that confer the greatest relative value must be identified. Using data from CATT, we find that, compared with as-needed dosing of bevacizumab, the ICERs of monthly bevacizumab and monthly ranibizumab for neovascular AMD are $242 357/QALY and $10 708 377/QALY, respectively. Furthermore, as-needed ranibizumab was dominated by as-needed bevacizumab, meaning that as-needed ranibizumab is more costly and less effective.
