Patent for Oncoral approved in Japan


Ascelia Pharma AB (publ) (ticker: ACE) (“Ascelia”) today announced that the patent application for Oncoral has been approved in Japan. The approval in Japan adds to the already obtained patents in the US and a selected number of countries in Europe and China. The patent secures the intellectual property protection rights for Oncoral until year 2035 plus potential patent extension.

“We are very pleased to also have the patent for Oncoral approved in Japan as the unmet medical needs for gastric cancer treatment in Japan are significant. More than 115,000 Japanese were diagnosed with gastric cancer in 2018 and the incidence rate is around five times higher than US and Europe, so the need for improved treatment options for these patients is great”, said Carl Bjartmar, MD, PhD, Chief Medical Officer at Ascelia Pharma.

Ascelia Pharma is currently preparing Oncoral for Phase 2 development after the promising Phase 1 results, which were published in 2019. Oncoral is an oral tablet formulation of irinotecan intended for combination use as a chemotherapeutic treatment of unresectable and metastatic gastric cancer. Intravenous irinotecan has already demonstrated safety and efficacy in the treatment of colorectal and pancreatic cancer. Having an oral tablet formulation of irinotecan, Oncoral has the potential to provide gastric cancer patients with an opportunity to receive chemotherapy at home, and at the same time reduce resource requirements in the health care system.

The patent for Oncoral, with the international publication number WO/2015/107131, covers Solid Oral Dosage form of irinotecan for treatment of cancer.
