SAN DIEGO, July 27, 2017 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a precision medicine biotechnology company, announced today that the U.S. Food and Drug Administration (FDA) has accepted its Investigational New Drug (IND) Application for PCM-075, a Polo-like Kinase 1 (PLK1) inhibitor, and has provided authorization to proceed with the treatment of patients with AML. Trovagene submitted its IND for a Phase 1b/2 clinical trial of PCM-075 in patients with AML to the FDA on June 27, 2017.
The Phase 1b/2 clinical trial will be led by Hematologist Jorge Eduardo Cortes, M.D., Deputy Department Chair, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center.
"The FDA's timely acceptance of our IND application and Phase 1b/2 protocol is an important milestone for Trovagene," said Bill Welch, Chief Executive Officer of Trovagene. "We have already received positive indications of interest from numerous key investigators and clinical institutions as we make preparations to initiate our trial in the U.S. Also, we are fortunate to have Dr. Cortes as the Principal Investigator on our trial given his vast experience in leukemia and his prior work with PLK1 inhibitors."
Clinical Study Details
The Phase 1b/2 is an open-label trial to evaluate the safety and anti-leukemic activity of PCM-075 in combination with decitabine in subjects with AML. The Phase 1b subjects will have relapsed, or have resistant disease to three or fewer prior therapeutic regimens. The Phase 2 subjects will have received no more than one prior regimen for the treatment of their AML, have either relapsed or refractory disease, and are judged not to be candidates for re-induction therapy. Newly diagnosed subjects will be included if they have not received prior therapy for their disease, and are ineligible for, or have refused, standard intensive induction therapy.
The Phase 1b is a dose escalation trial of PCM-075 in combination with decitabine to evaluate drug safety, tolerability, dose and scheduling, and determine a recommended clinical treatment dose for the Phase 2 continuation trial. The initial Phase 1b dose level of 12 mg/m2/day will be increased by 50% increments to reach the maximum clinical dose for AML patients. Pharmacokinetics of PCM-075 and correlative biomarker activity will be assessed prior to the initiation of Phase 2.
The Phase 2 continuation trial is open-label with administration of the recommended PCM-075 clinical dose in combination with decitabine. Doses of PCM-075 will be administered orally each day for five consecutive days in a 28-day cycle in both Phase 1b and Phase 2. Trovagene expects approximately 60 patients to be dosed with PCM-075 and evaluated in the Phase 1b/2 trial. PCM-075 will be supplied as hard gelatin capsules and will be manufactured by NerPharMa, a pharmaceutical manufacturing company and a subsidiary of Nerviano Medical Sciences.
About Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a hematologic malignancy in which myeloid lineage cells of the bone marrow cease to differentiate appropriately, resulting in a marked increase in the number of circulating immature blast cells. As a consequence, the counts of mature red blood cells, platelets, and normal white blood cells decline, causing fatigue, shortness of breath, bleeding, and increased susceptibility to infection. The Surveillance, Epidemiology and End Results (SEER) program estimates the annual incidence rate of AML in the United States (US) to be approximately 21,000 cases in 2017. Rates of new AML cases have been rising an average of 3.1% each year over the last 10 years. The median age of AML diagnosis is 68 years of age, and approximately 45% of new diagnoses are among patients age 70 years or older.
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. 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.
