This new patent protects the intellectual property of Onxeo relating to combined preparations comprising conjugated nucleic acid molecules, including its lead product candidate AsiDNA and a PARP inhibitor, as well as the use of the combined preparations for the treatment of cancer. Under the patent, AsiDNA and the PARP inhibitor may be present in one combined dosage form, or as part of separate dosage forms for sequential administration of the respective drugs. This European patent has a term expiring in mid-2036.
Onxeo has conducted extensive preclinical studies of AsiDNA in combination with various PARPi. These studies show that the combination has a strong synergistic anti-tumor activity in solid tumors, regardless of the genetic mutation status of the tumor. This synergy appears to be a class effect with all PARPi. Combination with AsiDNA could therefore represent an opportunity to expand PARPi indications to HR proficient tumors, which account for approximately 70% of tumors.
"This patent covering the combination of AsiDNA with any PARP inhibitor further reinforces our extensive patent portfolio, which is a key component of the value of AsiDNA. Our strong intellectual property position is an integral part of the Company’s business model, which aims to progress disruptive compounds up to the most valuable clinical inflexion points and then to partner or license them," said Judith Greciet, Chief Executive Officer of Onxeo.
