Trovagene Announces Fourth Quarter and Full-Year 2018 Results

Trovagene Announces Fourth Quarter and Full-Year 2018 Results

SAN DIEGO, CA March 6, 2019 Trovagene, Inc. (Nasdaq: TROV), a clinical-stage oncology therapeutics company, using a precision medicine

approach to develop drugs that target cell division (mitosis) for the treatment of leukemias, lymphomas and solid tumor cancers, today announced company highlights and financial results for the fourth quarter and full-year ended December 31,

2018. The company is issuing this press release in lieu of conducting a conference call.

We are pleased with the progress we are making in the

clinical development of onvansertib for the treatment of cancers and indications where there is a significant need to bring new therapeutic options to physicians and their patients Acute Myeloid Leukemia (AML), metastatic Castration-Resistant

Prostate Cancer (mCRPC) and metastatic Colorectal Cancer (mCRC), said Dr. Thomas Adams, Chief Executive Officer and Chairman of Trovagene. Our AML trial continues to advance and data shows that the combination of onvansertib and standard-of-care chemotherapy is demonstrating both a favorable safety profile and showing activity in greater than 88% of evaluable patients treated to-date, which is very encouraging. In January, we received a study may proceed notification from the FDA for our Phase 1b/2 trial in mCRC and expect that enrollment in this trial, which is being funded

by PoC Capital, will begin mid-year. We anticipate having data readouts from our Phase 2 trial in mCRPC throughout 2019, and recently presented a poster at the Genitourinary Cancers Symposium (ASCO-GU), overviewing the trial and confirming the safety of the combination of onvansertib and Zytiga . We will also be presenting safety and preliminary

clinical data from our Phase 1b/2 trial in AML and Phase 2 trial in mCRPC at the American Association for Cancer Research (AACR) annual conference in early April, 2019.

Dr. Adams added, We achieved a number of key milestones in 2018, including: Successful completion of the first three dose levels, without any

dose-limiting toxicities, in the Phase 1b segment of our AML trial; granting of Orphan Drug Designation in Europe for the treatment of AML; presentation of preliminary clinical data from our AML trial at the American Society of Hematology (ASH)

conference in December; opening of our mCRPC Phase 2 trial to full enrollment, following confirmation that the combination of onvansertib and Zytiga is safe and well tolerated in the safety lead-in phase; submission of a new IND and protocol for our Phase 1b/2 trial in mCRC in December; strengthening of our patent portfolio around our drug candidate, onvansertib, with the issuance of two new patents;

and entering into an exclusive license agreement with MIT to develop combination therapies that include anti-androgen or androgen antagonist and a Polo-like Kinase (PLK) inhibitor (onvansertib) for the treatment of cancer.

The Company has advanced its business in 2018, and to-date in 2019, with the following activities and milestone

On February 14, 2019, Trovagene announced the presentation of a poster reviewing its ongoing Phase 2

study evaluating onvansertib in combination with Zytiga (abiraterone acetate)/prednisone in patients with metastatic Castration-Resistant Prostate Cancer (mCRPC) at the Genitourinary Cancers

Symposium (ASCO-GU) in San Francisco, CA. The data featured demonstrates the safety and tolerability of onvansertib in combination with Zytiga which

was confirmed in the safety lead-in portion of the trial that was completed prior to opening the trial to full enrollment. In addition, a second arm is planned with the goal of maximizing clinical activity by

reducing the dosing schedule from the current 21-day cycle to a 14-day cycle.

On January 29, 2019, Trovagene announced an agreement with PoC Capital to fund its

Phase 1b/2 trial of onvansertib in combination with FOLFIRI and Avastin in patients with mCRC with a KRAS mutation. Trovagene submitted an Investigational New Drug (IND) application and protocol to the FDA on December 19, 2018, and received a

study may proceed notification from the FDA, 28-days later, on January 16, 2019. The trial will be conducted at two prestigious cancer centers in the U.S.; USC Norris Comprehensive Cancer

Center and The Mayo Clinic.

On January 23, 2019, Trovagene announced the issuance of a new patent (10,155,006), entitled Combination Therapies and Methods of Use Thereof for

Treating Cancer, by the U.S. Patent and Trademark Office (USPTO). This patent broadens previously issued patent (9,566,280), by expanding the use of Onvansertib to encompass combination therapies with any anti-androgen and androgen antagonist

drug, such as Zytiga , Xtandi and Erleada for the treatment of metastatic

and non-metastatic castrate-resistant prostate cancer. The issuance of this patent further strengthens Trovagene s existing intellectual property portfolio obtained with the licensing of exclusive global

development and commercialization rights to onvansertib from Nerviano Medical Sciences in March, 2017.

On December 3, 2018, Trovagene announced presentation of data from its ongoing

Phase 1b/2 study evaluating onvansertib in combination with standard-of-care chemotherapy in Acute Myeloid Leukemia (AML) at the 60th American Society of Hematology (ASH) annual meeting.

The date presented in a poster demonstrated that

onvansertib, in combination with LDAC or decitabine is benefiting patients who have relapsed/refractory AML and that the combination is safe and well tolerated, with no serious adverse events (SAEs) reported

On October 24, 2018, Trovagene announced that the U.S. Patent and Trademark Office (USPTO) has

allowed claims that affirms broad coverage of NPM1 mutation testing; Patent Application

14/750331, entitled Nucleophosmin Protein (NPM) Mutants, Corresponding Gene Sequences and Uses Thereof. This patent encompasses broad claims around the assessment of NPM1 mutational

status in any cancer type, including acute myeloid leukemia (AML). This not only aligns with the Company s current biomarker strategy and clinical development of onvansertib in AML, but also strengthens the revenue generating potential for

On October 3, 2018, Trovagene announced that it has entered into an exclusive patent license

agreement with the Massachusetts Institute of Technology (MIT). Under the agreement, Trovagene has exclusive rights to develop combination therapies that include anti-androgen or androgen antagonist and a Polo-like Kinase (PLK) inhibitor for the

treatment of cancer. The exclusive license agreement is part of Trovagene s strategy to explore the efficacy of Onvansertib, its first-in-class, 3rd generation,

highly-selective, oral PLK1 inhibitor, in combination with anti-androgen drugs in cancers including prostate, breast, pancreatic, lung and gastrointestinal. There is a need for new therapies that effectively treat cancers that depend on internal

androgen signaling, such as castration-resistant prostate cancer, as well as cancers which over-express androgen receptor (AR), or are otherwise dependent on the synthesis of steroid hormones for their growth, such as some breast cancers. In-vitro and in-vivo preclinical research demonstrates a unique synergistic effect with the combination of PLK inhibitors and anti-androgens, which was the precursor that led

to the current Phase 2 trial of onvansertib in combination with Zytiga (abiraterone acetate)/prednisone that is being conducted at the three Harvard Medical Cancer Centers.

On September 27, 2018, Trovagene announced completion of the second dosing cohort of onvansertib,

its first-in-class, 3rd generation, highly-selective oral Polo-like Kinase 1 (PLK1) Inhibitor, in combination with standard-of-care decitabine, in its Phase 1b/2 clinical trial in patients with Acute Myeloid Leukemia (AML). All three patients in the cohort successfully completed treatment with onvansertib at 18mg/m2,

administered orally, once daily, on days 1-5 of the treatment cycle, in combination with decitabine and the combination was well tolerated. The Safety Review Committee (SRC) has recommended escalating to the

next dose level of onvansertib at 27mg/m2 (approximately a 50% increase) in combination with decitabine.

On September 5, 2018, Trovagene announced it has developed a method for predicting response to

treatment by measuring the ability of onvansertib, a first-in-class, 3rd generation, oral and highly-selective Polo-like Kinase 1 (PLK1) inhibitor, to inhibit PLK1 in

patients with Acute Myeloid Leukemia (AML). PLK1 uniquely phosphorylates translational control tumor protein (TCTP) to form pTCTP and inhibition of this enzymatic activity by onvansertib appears to be predictive of patient response to treatment. In

the ongoing Phase 1b/2 open label clinical

trial in AML, PLK1 inhibition is being assessed 3-hours following administration, at the approximate peak concentration (Cmax) of onvansertib. In the first six patients treated, the greatest target engagement, or inhibition of PLK1, was observed in the three patients who showed a response to treatment.

Trovagene announced that the European Commission (EC) has endorsed the positive opinion of the Committee for Orphan Medicinal Products (COMP) and has granted Orphan Drug Designation (ODD) for onvansertib, a first-in-class, 3rd generation, oral and highly-selective Polo-like Kinase 1 (PLK1) inhibitor, for the treatment of patients with Acute Myeloid Leukemia (AML). Orphan drug designation by the EC provides

regulatory and financial incentives to Trovagene, including reduced fees during the product development phase, direct access to centralized marketing authorization in the EU, and 10-year market exclusivity

following product approval.

On August 16, 2018, Trovagene announced completion

of the second dosing cohort 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), in its Phase 1b/2 clinical trial in patients with Acute Myeloid Leukemia (AML). All three

patients in the cohort successfully completed treatment with onvansertib at 18 mg/m2, administered orally, once daily, on days 1-5 of the treatment cycle, in combination with LDAC and the combination was well

tolerated. The Safety Review Committee (SRC) has recommended escalating to the next dose level of onvansertib at 27 mg/m2 (approximately a 50% increase) in combination with LDAC. Additionally, two patients in the three-patient cohort of onvansertib

at 18 mg/m2 in combination with decitabine have also successfully completed at least one cycle of treatment and recruitment of the third patient to complete this cohort is in process. Four of the eleven patients treated to-date remain on treatment, three are currently receiving a second cycle of treatment and one patient is scheduled to start a fifth cycle of treatment.

Fourth Quarter 2018 Financial Results

expenses were approximately $4.2 million for the three months ended December 31, 2018, an increase of million $0.2 million from $4.0 million for the same period in 2017. The increase in operating expenses is attributed to

advancing the onvansertib clinical development programs.

Net cash used in operating activities in the fourth quarter of 2018 was $3.6 million,

compared to $3.3 million in the fourth quarter of 2017. The year-over-year increase of $0.3 million can be attributed primarily to progress made with the clinical development of its drug candidate, onvansertib.

Research and development expenses increased by approximately $1.3 million to $2.5 million for the

three months ended December 31, 2018 from $1.2 million for the same period in 2017. The overall increase in research and development expenses was primarily due to the increased outside service costs for clinical studies related to the

development of our drug candidate, onvansertib. We expect increases in research and development costs to continue as we advance the onvansertib clinical development programs in AML, mCRPC and mCRC.

Selling, general and administrative expenses decreased by approximately $0.2 million to $1.7 million for the three months ended December 31,

2018 from $1.9 million for the same period in 2017. The reduction is primarily due to a decrease in stock-based compensation.

The weighted average

diluted shares of common stock outstanding used to calculate per share results for the three months ended December 31, 2018 was 3.8 million.

of December 31, 2018, Trovagene had approximately $11.5 million of cash and cash equivalents.
