Defence Successfully Completes the First Milestone of Its Collaboration Agreement with Orano

Vancouver, British Columbia–(Newsfile Corp. – July 18, 2023) – Defence Therapeutics Inc. (CSE: DTC) (FSE: DTC) (OTC Pink: DTCFF) (“Defence” or the “Company“) is pleased to announce that it has successfully reached the first milestone established in the Collaboration Agreement with Orano Support SAS on behalf of Orano SA (“Orano”), a world-renowned multinational company, headquartered in Chatillon, France, to develop the next generation radio-immunoconjugates using Defence’s intracellular targeting technology.

The first milestone consists of synthesising the AccuTOX^TM peptide containing the DOTA chelator and the Azide moiety. The DOTA chelator will be used to encapsulate the radioactive molecule, while the Azide moiety is used for antibody linking via click chemistry.

The following milestones consist in synthesising a second AccuTOX^TM variant containing a cathepsin B-dependent cleavable sequence (valine-citrulline). The conjugation of the uncleavable AccuTOX^TM peptide variant to the Herceptin antibody (trastuzumab) will be performed as well.

The development of novel radio-based therapies by combining Defence’s intracellular targeting technology with cancer-targeting antibodies will exhibit a higher specificity and selectivity, and it will also ensure increased therapeutic efficacy with lower adverse events.

“We are pleased to successfully be in line with the timeline of our Orano collaboration agreement to develop the first radio-immuno-conjugates therapy based on the Auger electron emitter. By combining Defence’s intracellular targeting expertise and radiochemistry expertise provided by Orano, we are confident to develop a best-in-class radiotherapeutics with enhanced efficacy,” said Sebastien Plouffe, Chief Executive Officer of Defence Therapeutics.
