Patents by Inventor Alexander M. Klibanov

Alexander M. Klibanov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11819550
    Abstract: Concentrated, low-viscosity, low-volume liquid pharmaceutical formulations of proteins have been developed. Such formulations can be rapidly and conveniently administered by subcutaneous (SC) or intramuscular (IM) injection, rather than by lengthy intravenous infusion. These formulations include low-molecular-weight and/or high-molecular-weight proteins, such as mAbs, and organophosphates. The viscosity of the formulation is significantly reduced by the addition of one or more organophosphates.

  • Publication number: 20230046381
    Abstract: Nucleic acid and cell preservative compositions. Methods of preserving nucleic acids and/or cells in a blood or other biological sample, and kits for preserving nucleic acids and/or cells in a blood or other biological sample are also described. The preservative compositions, methods and kits afford the isolation of genomic and cell-free DNA and RNA from myriad biological samples that display good yields, purity, integrity and, in the context of RNA, amplifiability.

  • Publication number: 20210085792
    Abstract: Concentrated, low-viscosity, low-volume liquid pharmaceutical formulations of proteins have been developed. Such formulations can be rapidly and conveniently administered by subcutaneous or intramuscular injection, rather than by lengthy intravenous infusion. These formulations include low-molecular-weight and/or high-molecular-weight proteins, such as mAbs, and viscosity-lowering agents that are typically bulky polar organic compounds, such as many of the GRAS (US Food and Drug Administration List of compounds generally regarded as safe) and inactive injectable ingredients and FDA approved therapeutics.

  • Publication number: 20200345723
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. In a preferred embodiment, a drug is modified to increase its lipophilicity. In some embodiments the modified drug is homogeneously dispersed within spherical microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and/or organic solvent insoluble. The abuse-deterrent composition retards the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is passes through the GI tract.

  • Patent number: 10500317
    Abstract: Orthopedic and dental implants coated with an antibacterial coating and methods of making and using, are described herein. The implant can be coated with a hydrophobic, polycationic antibacterial polymer. The polymer can be covalently or non-covalently associated with the surface; however, in particular embodiments, the polymer is non-covalently associated with the surface. As shown in the examples below, clinical observations, digital radiography, and a battery of well-accepted ex vivo analytical methods show that the presence of a hydrophobic polycationic polymer coating, such as N,N-dodecyl,methyl-PEI coating on the surface of a metal implant, was effective in eliminating the clinical signs of infection in vivo in a large animal infection model. Moreover, the coated plates supported bone healing, and in fact decreased healing times, even in the presence of significant bacterial contamination compared to a control.
