Trovagene Announces Data from Acute Myeloid Leukemia (AML) Phase 1b/2 Trial of Onvansertib Chosen for Oral Presentation at ASH 2019 Annual Meeting

SAN DIEGO, Nov. 6, 2019 /PRNewswire/ -- Trovagene, Inc. (Nasdaq: TROV), a clinical-stage, Precision Cancer Medicine™ oncology therapeutics company developing drugs that target cell division (mitosis), for the treatment of various cancers including leukemia, prostate and colorectal, today announced that data from its completed Phase 1b and ongoing Phase 2 study of onvansertib in patients with relapsed/refractory acute myeloid leukemia (AML) has been accepted for an oral presentation at the 61st American Society of Hematology (ASH) Annual Meeting to be held December 7 - 10, 2019 in Orlando, Florida. In addition to the oral presentation, the abstract will also be published online in the November supplemental issue of the journal Blood.

"We believe that having our abstract selected for presentation in an oral session at ASH signifies the level of interest in onvansertib, a first-in-class, third-generation oral and highly-selective Polo-like Kinase 1 (PLK1) inhibitor," said Dr. Thomas Adams, Chief Executive Officer and Chairman of Trovagene. "Our results to-date are very encouraging and we continue to rapidly advance our Phase 2 trial of onvansertib in combination with standard-of-care chemotherapy to bring a much-needed new treatment option to patients with relapsed/refractory AML, including patients who have developed resistance to first-line treatment with venetoclax."

Oral Presentation Details

Title: Safety, Efficacy and Biomarker Analysis of a Phase 1b/2 Study of Onvansertib (ONV), a Polo-like Kinase 1 (PLK1) Inhibitor, in Combination with Low-Dose Cytrabine (LDAC) or Decitabine (DEC) in Patients with Relapsed/Refractory Acute Myeloid Leukemia (R/R AML) [Abstract 230]

Session Name: 616. Acute Myeloid Leukemia: Novel Therapy, Excluding Transplantation; Novel Targets and Combinations
Session Date: Saturday, December 7, 2019
Session Time: 2:00 PM - 3:30 PM EST
Presentation Time: 2:15 PM EST
Location: Orange County Convention Center, Chaplin Theater (W320)

About the Ongoing Phase 2 Clinical Trial of Onvansertib in AML
The Phase 2 AML trial (NCT03303339) of onvansertib in combination with decitabine will enroll 32 patients who are either treatment naïve and not candidates for induction therapy or who have relapsed disease after treatment with one prior regimen, including patients treated with venetoclax in combination with a hypomethylating agent. Patients will receive onvansertib, administered orally, on days 1 through 5 of each 21-28-day cycle in combination with decitabine. The primary efficacy endpoint of objective response (CR + CRi) will be assessed in patients who complete at least 1 cycle of treatment.

About Onvansertib
Onvansertib is a first-in-class, third-generation, oral and highly-selective adenosine triphosphate (ATP) competitive inhibitor of the serine/threonine polo-like-kinase 1 (PLK1) enzyme, which is over-expressed in multiple cancers including leukemias, lymphomas and solid tumors. Onvansertib targets the PLK1 isoform only (not PLK2 or PLK3), is orally administered and has a 24-hour 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 irinotecan, FLT3 and HDAC inhibitors, taxanes and cytotoxins. Trovagene believes the combination of 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 and triple-negative breast cancer (TNBC), as well as other types of cancer.

Trovagene has three ongoing clinical trials of onvansertib: A Phase 2 trial of onvansertib in combination with Zytiga® (abiraterone acetate)/prednisone in patients with mCRPC who are showing signs of early progressive disease (rise in PSA but minimally symptomatic or asymptomatic) while currently receiving Zytiga® (NCT03414034); a Phase 1b/2 Study of onvansertib in combination with FOLFIRI and Avastin® for second-line treatment in patients with mCRC with a KRAS mutation (NCT03829410); and a Phase 1b/2 (Phase 1b completed in 2019) clinical trial of onvansertib in combination with low-dose cytarabine or decitabine in patients with relapsed or refractory AML (NCT03303339). Onvansertib has been granted orphan drug designation by the FDA in the U.S. and by the EC in the European Union for the treatment of patients with AML.

Trovagene licensed onvansertib (also known as NMS-1286937 and PCM-075) from Nerviano Medical Sciences (NMS), the largest oncology-focused research and development company in Italy, and a leader in protein kinase drug development. NMS has an excellent track record of licensing innovative drugs to pharma/biotech companies, including Array (recently acquired by Pfizer), Ignyta (acquired by Roche) and Genentech.
