  • Patent number: 11523988
    Abstract: The present disclosure is directed to oral vaccine dosage forms and processes for producing the oral vaccine dosage forms. The dosage forms include lipid-based vesicles (e.g., virosomes, liposomes) harboring an immunogenic amount of at least one vaccinal target molecule, with or without adjuvant. Specifically, Applicants discovered a combination of the composition of the liquid virosome concentrates, the composition of the base matrix for the solid dosage form formulation (excluding the virosome concentrate), and the manufacturing conditions for the dosage forms that can produce a freeze dried sublingual dosage form having physical robustness, particle and antigen integrity and stability.

  • Patent number: 11517533
    Abstract: Described herein is a method for forming multi-layer drug dosage forms having at least two layers. In the method, a first formulation comprising a non-gelling matrix forming agent and having a first density is dosed into a preformed mold. A second formulation comprising a non-gelling matrix former and having a second density not equal to the first density is subsequently dosed into the preformed mold. Then, the combination of the formulations dosed into the mold is freeze dried to form the multi-layer dosage form having at least two layers. The use of a density difference between the first and second formulations ensures formation of a product with two distinct layers.

  • Publication number: 20210207003
    Abstract: The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. After reducing the endotoxin level of the gelatin-salt solution, the low endotoxin gelatin-salt solution is desalted to remove the salt, thereby producing a low endotoxin gelatin solution.

  • Patent number: 11026883
    Abstract: Disclosed herein is a solid lyophilized vaginal dosage form that can have an effective amount of at least one active ingredient, a crystalline structure forming agent in an amount of about 5 wt. % to about 40 wt. %, based on the total weight of the lyophilized dosage form, and at least one polymeric mucoadhesive matrix forming agent. The dosage form can have a pH of about 4.0 to 5.0, and can disintegrate within 120 seconds after being contacted with a vaginal mucosa. A method of delivering an active ingredient to the vaginal mucosa using the disclosed solid dosage form is also described.

  • Patent number: 7972621
    Abstract: The invention disclosed herein relates to a pharmaceutical composition comprising a carrier and an active ingredient, wherein the carrier is at least one fish gelatin predetermined on the basis of the molecular weight profile of the gelatin. In some embodiments, particularly when the concentration of carrier comprises a relatively lower percentage of the total composition, the carrier may be exclusively a high molecular weight fish gelatin, or may be comprised of a mixture with standard molecular weight gelatin in which high molecular weight gelatin comprises a predominant portion. In those embodiments where the concentration of carrier comprises a relatively larger percentage of the total composition, the carrier may be an exclusively standard molecular weight fish gelatin, or may be comprised of a mixture in which standard molecular weight gelatin comprises a predominant portion. Thus, compositions may be designed to optimize performance for various required gelatin concentration formulations.
