  • Publication number: 20240082367
    Abstract: The present invention relates antidotes to anticoagulants targeting factor Xa. The antidoes are factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. The derivatives describe herein lack or have reduced intrinsic coagulant activity. Disclosed herein are methods of stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.

  • Publication number: 20230047917
    Abstract: The present disclosure is directed to medium chain length polyhydroxyalkanoate (mcl-PHA) copolymers, and to chewing gum bases and chewing gums comprising the mcl-PHA copolymers. In some instances, the mcl-PHA copolymers may partially or completely replace conventional petroleum-based gum base polymers, including elastomers, in the chewing gum and gum base. The chewing gums and gum bases of the present disclosure may be free or substantially free of petroleum-based ingredients. Chewing gums comprising the mcl-PHA copolymers of the present disclosure may also have enhanced degradability as compared to conventional chewing gums.

  • Publication number: 20220322694
    Abstract: The present disclosure is directed to chewing gum bases, where mineral filler in the gum base formulation has been replaced with a polyol. The chewing gum bases of the present disclosure are thus essentially free of mineral filler, and contain a polyol, such as mannitol. Also disclosed are processes for producing the chewing gum bases. The processes of the present disclosure utilize polyol as a replacement for mineral fillers during various production stages. Confectionery products, such as chewing gums, that comprise the chewing gum bases are also disclosed.

  • Publication number: 20210177001
    Abstract: A method is provided for making a molten, deposited confectionery product, such as a chewing gum product. In an embodiment of the method for making a chewing gum product, one or more sugar alcohols are blended and melted before adding gum base and other ingredients. The process allows depositing at cooler temperatures than previously believed possible, which simplifies safe processing and protects product quality. In cases where the product is deposited in molds which are part of the packaging, the lower depositing temperatures allow greater flexibility in packaging materials and processes than when the sugar alcohols and other ingredients such as gum base are melted together. A product of the method also is provided.
