  • Publication number: 20210252153
    Abstract: A composition comprising poly(amidoamine) (PAMAM) hydroxyl-terminated dendrimers covalently linked to at least one therapeutic, prophylactic or diagnostic agent for the treatment or alleviation of one or more symptoms of a brain tumor have been developed. The dendrimers comprise one or more ethylene diamine-core poly(amidoamine) (PAMAM) hydroxyl-terminated generation-4, 5, 6, 7, 8, 9, or 10, most preferably generation 6 (G4-10-OH) dendrimers. The G6 dendrimers have demonstrated unexpectedly high uptake into the brain. The dendrimers provide a means for selective delivery through the blood brain barrier (“BBB”) of chemotherapeutic, immunotherapeutic and palliative agents. The dendrimers also have the advantage that two different classes of compounds, having one or more mechanisms of action can be bound to the dendrimers, providing simultaneous delivery. The dendrimers may be administered alone by intravenous injection, or as part of a multi-prong therapy with radiation.

  • Patent number: 10195190
    Abstract: Local delivery formulations of the antineoplastic and microbicide agent acriflavine, and methods of making and using thereof are significantly more efficacious at increasing the median survival of subjects with proliferative disease than systemic administrations of acriflavine. The local delivery formulations of acriflavine show a dose-dependent increase in the median survival of subjects. The local delivery forms provide the increased efficacy without the toxicity associated with systemic administration of the agent.
