Trovagene Presents Data Showing Sensitivity of Triple Negative Breast Cancer (TNBC) Cell Lines to PCM-075 and Synergy with Zytiga® at San Antonio Breast Cancer Symposium (SABCS)
Targeted treatment with highly selective Polo-like Kinase 1 inhibitor, PCM-075, may represent a new option in TNBC, particularly in combination with other abiraterone acetate
SAN DIEGO, Dec. 7, 2017 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a precision medicine biotechnology company, today announced that preclinical data demonstrating the sensitivity of triple negative breast cancer (TNBC) cell lines to PCM-075, its highly selective Polo-like kinase 1 (PLK1) Inhibitor, will be featured as a Poster Presentation at the 40th San Antonio Breast Cancer Symposium (SABCS) on December 7th, from 5:00 – 7:00 PM CST, in San Antonio, Texas.
Trovagene's poster entitled, Sensitivity of Triple Negative Breast Cancer Cell Lines to PCM-075, a Highly Selective Polo-like Kinase 1 Inhibitor, presents the preclinical analysis of 40 cancer cell lines and demonstrates that triple negative breast cancer (TNBC) cell lines are 20-fold more sensitive to PCM-075 than estrogen receptor positive (ER+) breast cancer cells lines.
Polo-like Kinase 1 (PLK1) is known to be over-expressed in many hematologic and solid tumor cancers, including breast cancer. PLK1 inhibition by PCM-075 induces cell-cycle arrest and apoptosis, or tumor cell death in numerous tumor cell lines, including TNBC cell lines. Additionally, a subset of TNBC cell lines harbor the androgen receptor (AR) and androgen can promote tumor growth. The presentation data indicates that PCM-075 in combination with anti-androgen, abiraterone acetate (Zytiga® - Johnson & Johnson), are synergistic in inducing cell death within an AR+ TNBC cell line.
"TNBC is a heterogeneous cancer with a poor prognosis. The marked synergy shown in preclinical studies with PCM-075 in combination with therapies, such as abiraterone acetate (Zytiga®), may provide a new therapeutic option for TNBC patients," said Mark Erlander, Chief Scientific Officer of Trovagene.

Session Name: Tumor Cell and Molecular Biology: New Drugs and Mechanisms
Location: Poster Session 3 – Hall 1
Date and Time: Thursday, December 7th – 5:00 pm – 7:00 pm CST
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 multiple hematologic and solid tumor cancers. Studies have shown that inhibition of polo-like-kinases can lead to tumor cell death, including a Phase 2 study in Acute Myeloid Leukemia (AML) where response rates up to 31% were observed when used in conjunction with a standard therapy for AML (low-dose cytarabine-LDAC) versus treatment with LDAC alone with a 13.3% response rate. A Phase 1 open-label, dose escalation safety study of PCM-075 has been completed in patients with advanced metastatic solid tumor cancers, and published in Investigational New Drugs.
Trovagene is initiating a Phase 1b/2 clinical trial with PCM-075 in AML that was accepted by the National Library of Medicine (NLM) and is now publicly viewable on www.clinicaltrials.gov. The NCT number assigned by clinicaltrials.gov for this study is NCT03303339. PCM-075 has been granted Orphan Drug Designation by the FDA for the treatment of patients with AML.
PCM-075 only targets PLK1 isoform (not PLK2 or PLK3), is oral, has a 24-hour drug half-life with reversible on-target hematologic toxicities. Trovagene believes that targeting only PLK1 with reversible on-target activity and an improved dose/scheduling protocol can significantly improve on the long-term outcome observed in previous studies with a PLK inhibitor in AML.
PCM-075 has demonstrated synergy in preclinical studies with over 10 chemotherapeutic and target agents used in hematologic and solid tumor cancers, including FLT3 and HDAC inhibitors, taxanes, and cytotoxins. Trovagene believes the combination of its targeted PLK-1 inhibitor, PCM-075, with other compounds has the potential for improved clinical efficacy in Acute Myeloid Leukemia (AML), Castration-Resistant Prostate Cancer (CRPC), Non-Hodgkin Lymphoma (NHL), Triple Negative Breast Cancer (TNBC) and Adrenocortical Carcinoma (ACC).
