  • Publication number: 20240122918
    Abstract: A drug delivery device comprising: a first layer comprising a first coaxially electrospun nanofiber membrane; a second layer comprising a second coaxially electrospun nanofiber membrane; a first therapeutic agent integrated into the first coaxially electrospun nanofiber membrane; and a second therapeutic agent integrated into the second coaxially electrospun nanofiber membrane. The second therapeutic agent is different from the first therapeutic agent.

  • 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.

  • Publication number: 20080260834
    Abstract: Localized delivery of 1,25 D3 directly to a target area using biodegradable polymeric matrices maximizes the efficacy of this drug while minimizing systemic exposure and toxicity. Anticalcemic analogs of 1,25 D3 have also been incorporated into controlled release polymer formulations to achieve efficacious intracranial concentrations of 1,25 D3 analogs for the treatment of intracranial tumors as well as neurodegenerative disorders such as Alzheimer's disease as well as to maximize the efficacy of these analogs in the treatment of systemic malignancies. The therapeutic efficacy of these formulations was demonstrated through a variety of studies in vitro and in vivo. Hybrid analogs of 1,25 D3 were incorporated into biodegradable polymer wafers composed of a polyanhydride copolymer of 1,3-bis(p-carboxyphenoxy)propane (CPP) and sebacic acid (SA) in a 20:80 molar ratio.
