Defence Therapeutics Receives USPTO Allowance For Patent Application Covering Next-Gen ADC Technology
Defence's Accum®-based ADCs have demonstrated enhanced intracellular delivery and cytotoxic activity in multiple preclinical cancer models compared to conventional ADCs. Upon grant, the '291 patent application will provide the Company with potential market exclusivity until 2043 for its proprietary second-generation Accum®-based ADCs, which include antibodies conjugated to innovative new constructs featuring a bile acid conjugated to a nuclear localization signal (NLS) derived from the ribosomal protein eS17 (RPS17).
This milestone builds on Defence's established patent portfolio for its foundational Accum® technology, which includes granted patents in the United States (US 11,352,437), Japan (JP 7,126,956), Australia (AU 2017233725), and Israel (IL 261765), with applications currently pending in Canada and Europe.
"Second-generation Accum®-based ADCs represent a significant advancement in both oncotherapy and targeted drug delivery," said Sébastien Plouffe, CEO and Founder of Defence Therapeutics. "This recent allowance underscores the innovation and versatility embedded in our ADC platform technology and reflects our commitment to developing novel, effective cancer treatments that push the boundaries of current ADC technologies."
This newly allowed U.S. patent application is poised to become the eighth granted U.S. patent in Defence's expanding portfolio, which now comprises seven published patent families.
