  • Publication number: 20240058459
    Abstract: Dendrimer compositions and methods for the treatment of one or more inflammatory and/or angiogenic diseases and/or disorders of the eye include hydroxyl-terminated dendrimers complexed or conjugated with one or more active agents for the treatment or alleviation of one or more symptoms of the diseases of the eye, and/or for diagnosing the diseases and/or disorders of the eye. The dendrimers may include one or more ethylene diamine-core poly(amidoamine) (PAMAM) hydroxyl-terminated generation-4, 5, 6, 7, 8, 9, or 10 dendrimers. The active agents may be VEGFR tyrosine kinase inhibitors including sunitinib or analogues thereof. Preferably, the compositions are suitable for administration via a systemic route to target activated microglia/macrophages in retina/choroid.

  • Publication number: 20230398241
    Abstract: Compositions and methods for detecting, monitoring and imaging inflammatory sites or tumors in a subject have been developed. Compositions of hydroxyl-terminated dendrimers conjugated to radionuclide(s) via ether linkages are provided for both imaging and radiotherapy (tumors). Methods for the non-invasive and specific positron emission tomography (PET) imaging or magnetic resonance imaging (MRI) of dendrimer conjugated to one or more imaging agents in a subject in vivo are also provided. The methods selectively deliver dendrimer conjugated to radionuclides or MRI contrast agents to reactive microglia or reactive immune cells in tumors in the recipient. In some embodiments, the dendrimers conjugated to imaging agents also deliver targeted radiotherapy agents to a tumor, and/or deliver additional diagnostic, therapeutic or prophylactic agents to reactive microglia in the recipient. Methods of making dendrimers conjugated to imaging agents are also described.

  • Publication number: 20230372499
    Abstract: Dendrimer compositions and methods for the treatment of cancer or autoimmune diseases are described. The compositions include dendrimers complexed or conjugated with one or more active agents for the treatment or alleviation of one or more symptoms of cancer or autoimmune diseases. The dendrimers may include one or more ethylene diamine-core poly(amidoamine) (PAMAM) hydroxyl-terminated generation-4, 5, 6, 7, 8, 9, or 10 dendrimers. The active agents may be immunomodulatory agents such as STING agonists, CSF1R inhibitors, PARP inhibitors, VEGFR tyrosine kinase inhibitors, MEK inhibitors, glutaminase inhibitors, TIE II antagonists, and CXCR2 inhibitors, and STING antagonists. Methods of using the dendrimer compositions to treat cancer, bone disease or inflammatory diseases are also provided.

  • Publication number: 20230364244
    Abstract: In some aspects, the disclosure provides methods of treating or preventing one or more symptoms of a kidney injury, disease or disorder in a subject in need thereof. In some embodiments, the method comprises administering to the subject a dendrimer complexed, covalently conjugated, or intra-molecularly dispersed or encapsulated with one or more therapeutic or prophylactic agents, in an amount effective to treat, alleviate or prevent one or more symptoms of a kidney injury, disease or disorder. In some embodiments, the dendrimer is a. generation 4, 5, 6, 7, or 8 poly(amidoamine)(PAMAM) dendrimers, and the therapeutic agents are one or more anti-inflammatory agents and/or PPAR-? agonists.
