Clinical Trial Summary

Age-related macular degeneration (AMD) is the leading cause of blindness after 50 years in industrialized countries, compromising daily activities and reducing quality of life. And whose treatment is one of the first health expenditures. Since September 2015, Bevacizumab, which does not have marketing authorization in AMD, has been given a temporary recommendation for use. Studies in other countries have shown that bevacizumab is cost-effective in the treatment of AMD compared to other anti-VEGF therapies used.

Description:

Numerous clinical trials have shown the effectiveness of Bevacizumab in the treatment of neovascular AMD as well that non-inferiority compared to Ranibizumab in terms of clinical efficacy at 1 year on visual acuity measured by the ETDRS scale of patients with neovascular AMD.

Regarding general tolerance, a recent meta-analysis including a large number of patients did not find any difference in systemic serious adverse reactions, neither any new special signal of tolerance with Bevacizumab. Concerning eye tolerance, there is no evidence of difference significant. Medico-economic analyzes carried out in other countries, as the United States or Brazil, have shown that Bevacizumab is cost-effective compared to Ranibizumab in AMD Neovascular.

The cost-utility analysis of the different methods of care patients with AMD will rely on the construction of a self-centered model built from: data available in natural history literature AMD in the absence of treatment; results of the network meta-analysis comparing effectiveness and tolerance of different strategies to assess; available data on adherence and persistence of treatments; pharmacovigilance data on the occurrence of side effects.

This analysis benefits from two related studies:

• Micro-costing, multicenter study of the preparation of intravitreal injections of Bevacizumab hospital pharmacy.

• Multicenter, prospective evaluation, cross-section, quality of life data and patient cost depending on the level of visual acuity.

According to the recommendations, at the beginning of the treatment, after the diagnosis of neovascular naive AMD, the patient will benefit from a fixed regimen of treatment by intravitreous injection of Bevacizumab or Ranibizumab or Aflibercept renewed every month for 3 months. Before each Intra-vitreous injection, the patient will be reviewed in consultation to collect the occurrence of events adverse reactions related to the injection of one of the three products. After 3 months, the monthly intra-vitreous injections will be left to the appreciation of the investigator.

The follow-up of the patients, during a specialized consultation will be spread out over 6 months according to the rhythm of a consultation by months and then 12 months.
