Immutep Limited (ASX: IMM; NASDAQ: IMMP), a clinical-stage biotechnology company developing novel LAG-3 immunotherapies for cancer and autoimmune disease, today announced the grant of a new patent (number 11,684,654) entitled “Combined Preparations for the Treatment of Cancer or Infection” by the United States Patent Office.
This United States patent was filed as a second divisional application and follows the grant of the United States parent patent and first divisional patent announced in December 2020 and March 2021, respectively.
The claims of the new patent build on the protection provided by the two previously granted patents, and are directed to methods of treating cancer by administering Immutep‘s lead active immunotherapy candidate eftilagimod alpha (“efti”) and a PD-1 pathway inhibitor, specifically BMS-936559, durvalumab, atezolizumab or avelumab. The expiry date of the patent is 15 November 2036 (including 312 days of patent term adjustment).
“We continue to build our patent estate around lead candidate efti, which is a unique biomolecule and shows great promise in being able to ultimately help diverse sets of cancer patients, including those with more complex needs. Here we add another key US patent which is closely aligned with our clinical development pipeline. These key patents support ongoing investment and allow us to confidently push forward across all of our business functions, including clinical, manufacturing, and business development,” said Marc Voigt, CEO of Immutep.
A continuation application and a further divisional application have been filed to pursue other embodiments of the invention.
