Based on co-drugs representing two different chemical entities and the co- and sequential administration of the two chemical entities, novel therapies for macular degeneration and TTR amyloidosis are provided. The first component (“selective TTR ligand”) is a chemical entity that binds to TTR in the RBP4 (retinol-binding protein 4)-TTR (transthyretin) complex, which participates in the delivery of retinol to the retina. This component reduces retinol transport from circulation to the retina and provides stabilization of the TTR tetramer. The second component (“C20-D3-visual chromophore-generating compound”) is a C20-D3 modified retinoid or carotenoid that, when metabolized in mammals, ultimately produces a C20-D3 visual chromophore, which is presented in the retina as C20-D3-9-cis-retinal or C20-D3-11-cis-retinal. Deuteration at C20 reduces the formation of lipofuscin biretinol, but other functions (such as providing a precursor for the synthesis of the visual chromophore 11-cis-retinaldehyde in vivo) are not reduced.
