Treatment of urothelial cancer using fusion polypeptide and enfortumab vedotin
A recently filed patent (Publication Number: US20240010701A1) outlines a method for treating urothelial cancer in individuals by administering a fusion polypeptide containing specific SIRPa D1 domain variants and Fc domain variants, along with enfortumab vedotin. The Fc domain variants include mutations in human IgG1, IgG2, and IgG4 Fc regions, as per the EU index of Kabat. The method is targeted towards individuals with locally advanced or metastatic urothelial cancer, including bladder, renal pelvis, ureter, or urethra cancer, who have previously received immune checkpoint inhibitors or platinum-containing chemotherapy.
Furthermore, the patent specifies that the individual should not have received prior treatment with monomethylauristatin-based antibody-drug conjugates or therapeutic agents blocking the CD47-SIRPa interaction. The administration of enfortumab vedotin and the fusion polypeptide is detailed in specific dosages and cycles, emphasizing intravenous administration. The fusion polypeptide, forming a homodimer, comprises distinct amino acid sequences, ensuring a targeted approach to treating urothelial cancer in human individuals. This patent presents a novel method that combines the use of fusion polypeptides and enfortumab vedotin to address urothelial cancer, offering potential advancements in cancer treatment strategies.
