  • Patent number: 11890328
    Abstract: A protein composition derived from silk fibroin, which composition possesses enhanced solubility and stability in aqueous solutions. The primary amino acid sequence of native fibroin is modified in the SDP such that cysteine disulfide bonds between the fibroin heavy and fibroin light protein chains are reduced or eliminated. Additionally, the composition can have a serine content that is reduced by greater than 40% compared to native fibroin protein, and the average molecular weight of the SDP is less than about 100 kDa.

  • Publication number: 20220411482
    Abstract: A biotherapeutic ophthalmic solution that may include a silk-derived protein as an active ingredient. Ophthalmic formulations are critical to the delivery of dosage forms, user requirements, and maintaining product stability. The formulations described herein are ophthalmic solutions that are comfortable to the user while product stability is maintained, even after long-term storage. Numerous excipients, manufacturing processes, and container closures were evaluated for their ability to stabilize silk-derived protein under ambient and accelerated conditions. Analyses showed that a small sub-set of protein-containing formulations meet the high physiochemical property standards required for therapeutic ophthalmic solutions.

  • Publication number: 20220017602
    Abstract: A biotherapeutic ophthalmic solution that may include a silk-derived protein as an active ingredient. The specific formulation of an ophthalmic composition is critical to meeting user requirements, to the delivery of dosage forms, and to maintaining product stability. The formulations described herein are ophthalmic solutions that are comfortable to the user while product stability is maintained, even after long-term storage. Numerous excipients, manufacturing processes, and container closures were evaluated for their ability to stabilize silk-derived protein under ambient and accelerated conditions. Analyses showed that only a very small subset of vehicle formulations were able to meet the high physiochemical property standards required for stabilizing protein-containing therapeutic ophthalmic solution formulations.

  • Patent number: 10064817
    Abstract: The present invention provides pharmaceutical compositions comprising azelastine, or a pharmaceutically acceptable salt or ester thereof including azelastine hydrochloride, and optionally one or more additional active agents. Preferred such compositions further comprise one or more pharmaceutically acceptable carriers or excipients that reduce the amount of post-nasal drip, and/or that minimize or mask the unpleasant bitter taste associated with post-nasal drip, of the compositions into the oral cavity, upon intranasal or ocular administration of the compositions. Especially effective excipients used in the compositions of the present invention are hypromellose as a viscosity modifier and sucralose as a taste-masking agent. The invention also provides methods of treating or preventing certain disorders, or symptomatic relief therefrom, by administering the compositions of the invention to a patient, e.g.

  • Publication number: 20140193466
    Abstract: The present invention provides for silk-derived compositions for treating a wide variety of ocular conditions. The composition is produced by processing the silk cocoon into a water-based solution (i.e., a dissolved silk), which is then cast into a film. The film may be transparent to visible light, and curved in shape for easy application to the ocular surface. The silk film may either self-adhere or be sutured to cover the wound. The degradation time of the film may range from 1 minute to 24 hours, or from 2 hours to 20 hours. The present compositions can help regenerate damaged corneal tissue, thus promoting healing.
