  • Patent number: 9867780
    Abstract: Disclosed is an optimized pharmaceutical formulation for the treatment of inflammatory conditions of the esophagus. A pharmaceutical formulation in the form of an orodispersible effervescent tablet is stable, easy to produce, and can be used without dissolving same in a liquid. It is not necessary to drink anything with the tablet as this would reduce the time that the budesonide solution remains in the affected regions of the esophagus. The effervescent tablet of the invention surprisingly resulted in an unexpectedly high rate of histological remission in patients with active eosinophilic esophagitis.

  • Patent number: 9017700
    Abstract: The present application describes a novel, advantageous purification method which guarantees the embryonation capability and the viability of a worm egg suspension. The T. suis worm eggs are first treated in a non-embryonated condition in a sulfuric acid solution at about =ph 2. Bacteria and viruses are thereby killed successfully. The germination number of yeasts and fungi is reduced. In a second step, the pH-value is increased and an orally tolerated preservative is added. Yeasts and fungi are thereby killed successfully. The suspension medium used in the second purification step can then be used as a culture medium for additional production (embryonation) and storage.

  • Patent number: 8993332
    Abstract: A method for determining the biological activity of embryonated Trichuris eggs is described, in which at least one of the following determinations is carried out: a) Determination and/or confirmation of the stage of the embryonal development of helminth eggs with the aid of quantitative PCR analysis by using suitable marker sequences for ascertaining the copy number of the genomic DNA, b) Determination of the metabolic activity of embryonated helminth eggs by means of biochemical and/or molecular biological methods, c) Determination of the inducibility of gene expression in embryonated helminth eggs, d) Microscopic determination of the motility of helminth larvae in the egg over long periods of observation after pre-incubation at increased temperatures and/or e) Determination of the hatching rate of Trichuris larvae in a laboratory animal, wherein the intact embryonated eggs recovered from the contents of the intestine are quantified compared to an internal standard.
