Trovagene Announces Completion of Cycle-One Dosing in First Patient Enrolled in its Phase 1b/2 Clinical Trial of PCM-075 in Acute Myeloid Leukemia (AML)

Trovagene Announces Completion of Cycle-One Dosing in First Patient Enrolled in

its Phase 1b/2 Clinical Trial of PCM-075 in Acute Myeloid Leukemia (AML)

SAN DIEGO, CA February 6,

2018 Trovagene, Inc. (NASDAQ: TROV), a precision medicine biotechnology company, today announced that the first patient has completed the first cycle of dosing with PCM-075 in combination with low-dose cytarabine in its Phase 1b/2 multicenter trial of patients with Acute Myeloid Leukemia (AML). Two clinical trial sites are currently screening and enrolling patients and five additional sites are planned to

be activated by the end of the first quarter. PCM-075 is the first oral PLK1-selective adenosine triphosphate competitive inhibitor to enter clinical trials with proven antitumor activity in hematologic and

solid tumor preclinical models.

This is an important milestone for Trovagene and for AML patients, said Bill Welch, Chief Executive Officer

of Trovagene. There has been little improvement in the treatment of AML for the past several decades, and survival rates for these patients lag behind many other blood cancers. Treatment with PCM-075

represents a promising therapeutic option for AML patients who are ineligible for intensive induction therapy, or who have relapsed or refractory disease. Our goal is to rapidly advance our development of

PCM-075 in combination with standard-of-care chemotherapy for these patients.

We are excited to be leading off the clinical evaluation of PCM-075, a potential new treatment option for

patients with Acute Myeloid Leukemia, said Alex Spira, M.D., Principal Investigator, Virginia Canceer Specialists, in Fairfax, Virgnia. Our initial patient enrolled in the Phase 1b/2 trial completed his first cycle of treatment with PCM-075 in combination with low-dose cytarabine, and we are pleased with how well this patient tolerated the combination regimen.

The Phase 1b/2 trial is a multi-center, open-label trial exploring the safety and efficacy of PCM-075 in combination

with standard-of-care chemotherapy in AML patients who are ineligible for intensive induction therapy or whose disease is relapsed or refractory. This trial is being 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.

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 multiple hematologic and solid tumor cancers.

Studies 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 up to 31% were observed when used in conjunction 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 PCM-075 has been completed in

patients with advanced metastatic solid tumor cancers, and published in Investigational New Drugs.

Trovagene is initiating a Phase 1b/2 clinical trial with PCM-075 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. PCM-075 has been granted Orphan Drug Designation by the FDA for the treatment of patients

PCM-075 only targets PLK1 isoform (not PLK2 or PLK3), is oral, has a

24-hour drug half-life with reversible on-target hematologic toxicities. Trovagene believes that targeting only PLK1 with reversible

on-target activity and an improved dose/scheduling protocol can significantly improve on the long-term outcome observed in previous studies with a PLK inhibitor in AML.

PCM-075 has demonstrated synergy in preclinical studies with over 10 chemotherapeutic and target agents used in

hematologic and solid tumor cancers, including FLT3 and HDAC inhibitors, taxanes, and cytotoxins. Trovagene believes the combination of its targeted PLK-1 inhibitor, PCM-075, with other compounds has the

potential for improved clinical efficacy in Acute Myeloid Leukemia (AML), Castration-Resistant Prostate Cancer (CRPC), Non-Hodgkin Lymphoma (NHL), Triple Negative Breast Cancer (TNBC) and Adrenocortical

About Acute Myeloid Leukemia

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
