Vaccine for treating or preventing c. difficile bacterial infection
A recently granted patent (Publication Number: US11938179B2) discloses a multivalent immunogenic polypeptide designed to target Clostridium difficile infections. The polypeptide consists of a binary toxin (CDT) portion, a Toxin A portion, and two Toxin B portions, each derived from a C. difficile toxin protein. The patent specifies the amino acid sequences for each portion, emphasizing a high degree of homology to specific sequences (at least 90%, 95%, 97%, 98%, or 99% homology). The arrangement of the portions, with the Toxin A portion positioned between the two Toxin B portions, and the presence of specific amino acid linkers between them, are also detailed in the claims.
Moreover, the patent covers a nucleic acid molecule encoding the polypeptide, along with a method for its preparation involving expression in an insect host cell and isolation using a non-ionic detergent. An immunogenic composition comprising the polypeptide and a suitable carrier, excipient, or diluent is also described, with the inclusion of an adjuvant, particularly a saponin-based adjuvant containing specific fractions in defined proportions. This patent highlights a novel approach to developing an immunogenic polypeptide targeting C. difficile infections, with a focus on specific amino acid sequences, arrangement, and production methods, offering potential advancements in combating this challenging medical condition.
