Syndax Pharmaceuticals, a clinical-stage epigenetics oncology company, today announced allowance by the European Patent Office for the patent application titled "N-(2-AMINOPHENYL)-4[N-(PYRIDINE-3-YL) - METHOXYCARBONYL - AMINOMETHYL]-BENZAMINE (MS-275) POLYMORPH B." This allowance follows the recent US issuance which was granted in June adding to the extensive patent estate for the Company's lead product, entinostat.
The patent covers the novel polymorph form B of the oral histone deacetylase inhibitor, entinostat, which is the specific polymorph being developed by Syndax for combination therapy with aromatase inhibitors for metastatic breast cancer and epidermal growth factor receptor tyrosine kinase inhibitors for advanced non-small cell lung cancer.
"This European allowance combined with the recent US issuance provides a strong patent position for entinostat, our lead product candidate, as we move forward into phase 3 testing for women with metastatic breast cancer," said Joanna Horobin, MD, president and chief executive officer of Syndax. "We look forward to presenting the results from our randomized phase 2 placebo-controlled study in metastatic breast cancer at the ASCO 2011 Breast Cancer Symposium in September. We believe entinostat may help address the significant need to improve outcomes for the thousands of women in the United States living with metastatic breast cancer by extending the benefit of hormone therapy and delaying initiation of chemotherapy."
