Patents by Inventor Chandra Webb

Chandra Webb 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).

  • Publication number: 20200338199
    Abstract: The invention provides methods for preparing pharmaceutical formulations for injection such that upon injection the formulation does not cause erythrocyte agglutination, hemolysis, and/or cell shrinkage. To prevent agglutination, a pharmaceutical formulation ready for injection needs to have a sufficient ionic strength. To prevent hemolysis or cell shrinkage, a pharmaceutical formulation ready for injection needs to be about isotonic with respect to plasma. The invention provides methods that prepare pharmaceutical formulations for injection that have both the sufficient ionic strength to prevent agglutination and the requisite tonicity to prevent significant hemolysis or cell dehydration or shrinkage. The present methods involve the use of sodium chloride solutions that are about 25 mM to about 150 mM for reconstituting lyophilized cakes (or other non-liquid pharmaceutical formulations) into solution or for diluting pharmaceutical formulation solutions.

  • Publication number: 20110033464
    Abstract: The present invention provides compositions of Ig fusion proteins, especially compositions including an Ig fusion protein, a bulking agent, a disaccharide, a surfactant, and a buffer. In one aspect, these compositions are stable under long-term storage or at least one freeze/thaw cycle. The invention also provides methods of preparation of the Ig fusion protein compositions. In one aspect, compositions of the invention are lyophilized. In a further aspect, the compositions are lyophilized by a process that includes an annealing step.

  • Publication number: 20100124536
    Abstract: Hemophilia treatment by the inhalation of coagulation factors. Dry powder Factor IX is aerosolized to a mass median aerodynamic diameter of 4 ?m or less, with at least 90% monomer content, at least 80% activity level, and 10% water or less. The aerosol is slowly, and deeply inhaled into the lung, and followed by a maximal exhale.
