 Ranibizumab Lucentis is another monoclonal antibody to VEGF: it was directly cleaved from Bevacizumab to produce a lower molecular weight molecular that is more appropriate for use inside the eye. Whereas bevacizumab has been used off-label to treat nAMD, ranibizumab has been the subject of large Phase III controlled clinical trials 4,5 with robust safety analysis, and is licensed for the treatment of nAMD in Europe, the USA, and most countries. Neither bevacizumab nor ranibizumab are licensed for the treatment of diabetic retinopathy.
