| | SAN DIEGO, PRNewswire/ -- TrovaGene, Inc. (Nasdaq: TROV), a clinical-stage oncology therapeutics company, taking a precision medicine approach to develop drugs that target cell division (mitosis) for the treatment of leukemias, lymphomas and solid tumor cancers, today announced that two abstracts, highlighting data from the Company’s lead clinical programs of onvansertib in Acute Myeloid Leukemia (AML) and metastatic Castration-Resistant Prostate Cancer (mCRPC), respectively, have been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting, March 29 - April 3, 2019 in Atlanta, GA. 
The poster scheduled for presentation on Monday, April 1, 2019, will include safety and preliminary anti-leukemic activity data from the ongoing Phase 1b/2 clinical trial of onvansertib, a first-in-class, 3rd generation, highly-selective oral Polo-like Kinase 1 (PLK1) Inhibitor, in combination with standard-of-care low-dose cytarabine (LDAC) or decitabine in patients with relapsed or refractory AML. The first three dose escalation cohorts (12mg/m2, 18mg/m2 and 27mg/m2) have been completed with no patients experiencing dose-limiting toxicities and the fourth dose level cohort (40mg/m2) is fully enrolled. The poster scheduled for presentation on Tuesday, April 2, 2019, will feature safety and initial efficacy data from the ongoing Phase 2 clinical trial of onvansertib in combination with Zytiga® (abiraterone acetate)/prednisone in patients with mCRPC. The safety lead-in of three patients showed no dose-limiting toxicities or new toxicities from the combination regimen. A 29-patient expansion phase is ongoing. A second arm with a shortened dosing schedule of 14-days is being added to the trial and will enroll 32 additional patients. Patients will be alternately assigned to each arm. “We continue to be encouraged by the demonstrated safety and clinical benefit of onvansertib that we are seeing in our two ongoing clinical trials,” said Dr. Thomas Adams, Chief Executive Officer of Trovagene. “As open-label trials we plan to provide data readouts throughout the year, as well as sharing updates on our biomarker strategy that will enable us to identify patients who are most likely to respond to treatment with onvansertib.” Details of the poster presentations are provided below: Title: Phase 1b safety, Preliminary Anti-Leukemic Activity and Biomarker Analysis of the Polo-like Kinase 1 (PLK1) Inhibitor, Onvansertib, in Combination with Low-Dose Cytarabine or Decitabine in Patients with Relapsed or Refractory Acute Myeloid Leukemia

Abstract Number: CT102 About the Ongoing Onvansertib Phase 1b/2 Trial in AML
The Phase 1b/2 trial (NCT03303339) is a multi-center, open-label trial to evaluate the safety and efficacy of onvansertib in combination with standard-of-care chemotherapy in AML patients who have relapsed or refractory disease. In Phase 1b dose-escalation segment of the trial, the primary objective is to determine the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D), using a traditional 3+3 design. In Phase 2 the MTD or RP2D will be administered to 32 patients to evaluate preliminary antitumor activity and to continue to evaluate the safety and tolerability of onvansertib in combination with standard-of-care chemotherapy. This trial is being led by Jorge Cortes, M.D., Deputy Department Chair, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center and Amer Zeidan, MBBS, MHS, assistant professor of Medicine at Yale School of Medicine, and Hematology expert at Yale Cancer Center. The trial is being conducted at nine sites in the U.S. Title: A Phase 2 Study of the Polo-like Kinase 1 (PLK1) Inhibitor Onvansertib in Combination with Abiraterone (abi) and Prednisone in Patients with Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Abstract Number: CT161 About the Ongoing Onvansertib Phase 2 Trial in mCRPC
In this multi-center, open-label, Phase 2 trial, onvansertib in combination with the standard dose of Zytiga® (abiraterone acetate) and prednisone, all administered orally, is being evaluated for safety and efficacy. The trial will enroll up to 45 patients with mCRPC showing early signs of disease progression demonstrated by two rising PSA values separated by at least one week, while on Zytiga®/prednisone therapy. The primary efficacy endpoint is the proportion of patients achieving disease control after 12 weeks of study treatment, as defined by lack of prostate specific antigen (PSA) progression in patients who are showing signs of early progressive disease (rise in PSA but minimally symptomatic or asymptomatic) while currently receiving abiraterone acetate and prednisone (NCT03414034). The trial is being conducted at Beth Israel Deaconess Medical Center (BIDMC), Dana Farber Cancer Institute (DFCI) and Massachusetts General Hospital (MGH). About Onvansertib
Onvansertib is a first-in-class, 3rd generation, oral and highly-selective adenosine triphosphate (ATP) competitive inhibitor of the serine/threonine polo-like-kinase 1 (PLK 1) enzyme, which is over-expressed in multiple cancers, including leukemias, lymphomas and solid tumors. Separate studies with other PLK inhibitors 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 of up to 31% were observed when combined 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 onvansertib has been completed in patients with advanced metastatic solid tumor cancers and published in Investigational New Drugs. The maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) in this trial was 24 mg/m2. Trovagene has an ongoing Phase 1b/2 clinical trial of onvansertib in combination with standard-of-care chemotherapy in AML that was accepted by the National Library of Medicine (NLM) and is publicly viewable on www.clinicaltrials.gov. The NCT number assigned by clinicaltrials.gov for this study is NCT03303339. Onvansertib has been granted Orphan Drug Designation by the FDA in the U.S. and by the EC in the European Union (EU) for the treatment of patients with AML. Trovagene has an ongoing Phase 2 clinical trial of onvansertib in combination with Zytiga (abiraterone acetate)/prednisone in mCRPC that was accepted by the NLM and is publicly viewable on www.clinicaltrials.gov. The NCT number assigned by clinicaltrials.gov for this study is NCT03414034. Trovagene has a planned Phase 1b/2 clinical trial of onvansertib in combination with FOLFIRI and Avastin (bevacizumab) in metastatic Colorectal Cancer (mCRC) that was accepted by the NLM and is publicly viewable on www.clinicaltrials.com. The NCT number assigned by clinicaltrials.gov for this study is NCT03829410. Onvansertib targets the PLK1 isoform, only (not PLK2 or PLK3), is orally administered, has a 24-hour drug half-life with only mild to moderate side effects reported. Trovagene believes that targeting only PLK1 and having a favorable safety and tolerability profile, along with an improved dose/scheduling regimen will significantly improve on the outcome observed in previous studies with a former panPLK inhibitor in AML. Onvansertib has demonstrated synergy in preclinical studies with numerous chemotherapies and targeted therapeutics used to treat leukemias, lymphomas and solid tumor cancers, including FLT3 and HDAC inhibitors, taxanes, and cytotoxins. Trovagene believes the combination of its targeted PLK1 inhibitor, onvansertib, with other compounds has the potential to improve clinical efficacy in Acute Myeloid Leukemia (AML), metastatic Castration-Resistant Prostate Cancer (mCRPC), Non-Hodgkin Lymphoma (NHL), Colorectal Cancer, Triple Negative Breast Cancer (TNBC), as well as other types of cancer.
