EUCLISES PHARMACEUTICALS, INC. RECEIVES NOTICE OF PATENT ALLOWANCE FROM EUROPEAN PATENT OFFICE FOR NEW CLASS OF COMPOUNDS FOR TREATMENT OF CANCER, PAIN AND INFLAMMATION

 

St. Louis, MO – December 9, 2015 – Euclises Pharmaceuticals, Inc., a biopharmaceutical company focused on the discovery and development of novel COX-2 inhibitors for use in treating certain cancers, pain and inflammation, has received a Notice of Allowance from the European Patent Office (EPO) for Patent Application No. 12879240.5 entitled, “Deuterated Benzopyran Compounds and Application Thereof.” The covered compounds have been shown to be very potent and highly selective in the inhibition the COX-2 enzyme.

The patent broadly covers some of the Company’s novel compounds, including its lead drug ECP-1014, which has demonstrated significant slowing of tumor growth in animal models of cancer. Euclises is currently focused on completing the IND-enabling studies in anticipation of initiating clinical trials late in 2016 in patients with colorectal cancer.

COX-2 has been shown to play a critical role in tumorigenesis, progression and development of resistance to standard-of-care chemotherapies in a number of cancers, including NSCLC, CRC, pancreatic cancer, renal cell cancer, cutaneous squamous cell carcinoma and basal cell carcinoma. While the role of COX-2 in cancer has been well known for some time, older COX-2 inhibitors have not been effectively developed for oncology treatment, in part due to side effects that limit dosing. Use of these older inhibitors in initial clinical studies has, however, firmly validated the efficacy of COX-2 inhibition in cancer and also facilitated the identification of a non-invasive biomarker that allows selection and monitoring of patients whose tumors are dependent on the COX-2 pathway. Euclises’ new classes of COX-2 inhibitors appear to possess the favorable characteristics of the older drugs but are expected to support clinically optimal anti- cancer dose levels safely.
