| 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 presented updated data from its ongoing Phase 1b/2 study evaluating Onvansertib in combination with standard-of-care chemotherapy in Acute Myeloid Leukemia (AML).
The data, featured in a poster presentation at the 60th American Society of Hematology (ASH) Annual Meeting, demonstrate that Onvansertib, in combination with LDAC or decitabine, even at the dose-escalation phase of the trial, is benefiting patients who have relapsed/refractory Acute Myeloid Leukemia (AML), and that the combination regimen is safe and well-tolerated, with no serious adverse events (SAEs) reported to-date. Onvansertib is a first-in-class, 3rd generation, highly-selective oral Polo-like Kinase 1 (PLK1) Inhibitor that is being evaluated in an ongoing Phase 1b/2 clinical trial at nine sites in the U.S. AML is a rapidly progressing bone marrow cancer with poor survival rates compared to other leukemias. The standard of care for people with AML is intensive chemotherapy; however, for many elderly patients with AML intensive treatment is not an option. Additionally, patients with relapsed or refractory AML remain among the most challenging to treat and prognosis is poor. “AML patients with relapsed/refractory disease have very limited, if any, treatment options,” said Dr. Amer Zeidan, lead investigator and assistant professor of Medicine at Yale School of Medicine, and Hematology expert at Yale Cancer Center. “While we are still early in the trial where patients are being treated in the dose escalation phase, we are encouraged by the safety profile of onvansertib. Importantly, there are signs of preliminary efficacy we are already seeing in the dose escalation phase of the trial of onvansertib in combination with decitabine or low dose cytarabine. One patient has achieved an ongoing partial response; showing a significant reduction in blast count and hematologic count improvement, while 9 patients so far have stable disease. AML, especially when relapsed or refractory, is a biologically aggressive cancer, so prolonged periods of stable disease are considered clinically meaningful. We anticipate as we continue in the trial and reach the recommended Phase 2 dose that we will see additional evidence of clinical efficacy.” “A key component of our Onvansertib clinical development program is the integration of a predicative biomarker strategy to help identify patients who are more likely to respond to treatment,” said Dr. Mark Erlander, Chief Scientific Officer of Trovagene. “Thus far we have observed a rapid and durable inhibition of the PLK1 enzyme by Onvansertib in a subset of patients, which is also associated with a higher response to treatment, as measured by decreases in circulating and bone marrow leukemic blast cells. We believe this will provide a significant advantage as we advance our clinical trial in AML, and other cancers, and will enable us to select sub-populations of patients who will benefit most from treatment with Onvansertib.” Presentation Highlights: Background

Acute Myeloid Leukemia: Novel Therapy, Excluding Transplantation: Poster III Location: Hall GH (San Diego Convention Center) Date and Time: Monday, December 3, 2018; 6:00 PM - 8:00 PM About the Ongoing Onvansertib Phase 1b/2 Acute Myeloid Leukemia Trial 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 are ineligible for intensive induction therapy or whose disease is relapsed or refractory. 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. 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 with onvansertib 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. 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. 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.
