Trovagene Announces Expansion of Key Claims for its NPM1 Patent Portfolio for Acute Myeloid Leukemia

SAN DIEGO, June 26, 2017 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a precision medicine biotechnology company, today announced that the U.S. Patent and Trademark Office, and separately, the European Patent Office, have allowed claims for Patent Application 13/959739 and Patent Application EP10184598.0, respectively, entitled "Nucleophosmin Protein (NPM) Mutants, Corresponding Gene Sequences and Uses Thereof." These patents encompass NPM1 mutation detection and minimal residual disease (MRD) monitoring of patients with acute myeloid leukemia (AML). 

"These allowed NPM1 patent claims in the U.S. and Europe further strengthens the patent portfolio supporting our drug candidate, PCM-075, and its clinical development in AML," said Bill Welch, Chief Executive Officer of Trovagene. "Importantly, knowing the NPM1 mutational status of all AML patients is recommended within the National Comprehensive Cancer Network (NCCN) guidelines to help inform treatment decisions."

"We believe that monitoring for minimal residual disease and quantitative detection of NPM1 mutations will be an essential component in managing patients with AML, with the potential for closely following the impact of new treatments," said Sandra Silberman, MD, PhD, a Clinical Advisor and Hematologist/Oncologist at Duke VAMC.

About PCM-075

PCM-075 is a highly-selective adenosine triphosphate (ATP) competitive inhibitor of the serine/threonine polo-like-kinase 1 (PLK 1) enzyme, which is over-expressed in several different hematologic malignancies, as well as solid tumors such as breast, prostate, ovarian, lung, gastric and colon cancers. PCM-075 is orally bioavailable and has been explored in an initial Phase 1, open-label, dose-escalation safety study in patients with advanced metastatic solid tumor cancers. In this study, PCM-075 demonstrated an acceptable safety profile, as well as anti-tumor activity. Trovagene plans to initiate clinical trials of PCM-075 in AML, since it has significant advantages over prior PLK1 inhibitors evaluated in this indication, including a higher selectivity, greater potency, oral bioavailability and shorter half-life.
