  • Patent number: 11260024
    Abstract: Biopharmaceuticals, such as vaccine agents and probiotics, are encapsulated in carbohydrate-glass particles and embedded in an amorphous polymer substrate to produce polymeric compositions containing ambient-temperature stable biopharmaceuticals for syringeless administration to patients such as via dissolvable films, micro-needle patches and similar medical delivery devices. The amorphous polymer substrate is soluble in both water and a volatile organic solvent, yet the carbohydrate-glass particles are insoluble in the volatile organic solvent.

  • Patent number: 9469835
    Abstract: Significant research is being done to develop and improve delivery mechanisms for biopharmaceuticals and vaccines, including pulmonary (inhalation), nasal, transdermal, and oral alternatives. Market projections indicate that the delivery of proteins and vaccines by inhalation and oral formulation has become and will continue to be increasingly important. These delivery mechanisms, to be effective, will require better stabilization of the biologicals so that they can maintain potency and effectiveness at ambient temperatures for extended periods of time. The novel Preservation by Vaporization (PBV) Technology described herein provides cost-effective and efficient industrial scale stabilization of proteins, viruses, bacteria, and other sensitive biologicals, thereby allowing a production of products that are not possible to be produced by existing methods. The suggested new PBV process comprises primary drying under vacuum from a partially frozen state (i.e.

  • Publication number: 20100120014
    Abstract: A method of formulating high ambient temperature (room temperature and above) stable biologics (biologically active macromolecules, enzymes, serums, vaccines, viruses, pesticides, drug delivery systems, liposomes, cells suspensions, sperm, erythrocytes, other blood cells, stem cells, multicellular tissues, skin, heart valves) including secondary drying comprising at least two steps of stability drying at elevated temperature: 35° C., 40° C., 45° C., 50° C., and higher temperatures. The method could be applied to stabilize biologics encapsulated in alginate gel microspheres for better oral delivery. The method encompasses the following: microspheres are formulated using a cryo-encapsulation procedure comprised of mixing drops of frozen preservation mixture (To form the preservation mixture, biologics are mixed with preservation solutions containing sodium alginate.) with frozen drops of a calcium solution (i.e. calcium gluconate) and subsequent warming to form the gel particles.

  • Publication number: 20060240399
    Abstract: The method of preservation by vitrification, described in the present application, provides for storage of samples at higher temperatures than in conventional methods and can be applied to cells, multicellular tissues, organs and organisms. The method of the present invention includes preparing a solution of vitrification non-permeating co-solutes (amino acids, betaines, carbohydrates, or other non-permeating co-solutes that effectively decrease the chemical potential of permeating cryoprotectants in aqueous solutions), a permeating cryoprotectant and a non-permeating cryoprotectant (polyvinylpyrrolidone, polyethylene glycol, dextran, hydroxy ethyl starch, Ficoll, etc.), contacting a sample with the vitrification solution and storing the sample at a storage temperature. The method also includes the step of rehydrating the preserved sample in a rehydration solution prepared in the manner of the vitrification storage solution.
