Trovagene Receives Positive Opinion for Orphan Drug Designation in the European Union for PCM-075, Trovagene's Investigational Cancer Drug
SAN DIEGO, Aug. 1, 2018
SAN DIEGO, Aug. 1, 2018 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a clinical-stage oncology therapeutics company, developing targeted therapeutics for the treatment of leukemias/lymphomas and solid tumor cancers, today announced that the European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) has adopted a positive opinion recommending PCM-075 for designation as an orphan medicinal product for the treatment of Acute Myeloid Leukemia (AML). PCM-075 is a first-in-class, 3rd generation, highly selective, oral Polo Like Kinase 1 (PLK1) inhibitor, that is designed to target cell division (mitosis).
"The positive opinion from the EMAs Committee for Orphan Medicinal Products, based on our in vivo data supporting medical plausibility and the potential for significant benefit of PCM-075, marks another milestone in our efforts to improve the lives of patients suffering from AML," said Dr. Thomas Adams, Chairman and Interim Chief Executive Officer of Trovagene. "We believe that PCM-075, in combination with standard-of-care chemotherapies and targeted therapeutics, has the potential to provide significant clinical benefit with regard to efficacy and safety in patients with AML and we remain keenly focused on advancing our ongoing multi-center Phase 1b/2 clinical trial."
To be considered for Orphan Drug Designation in the EU, companies must provide data that demonstrates plausibility for use of the investigational therapy in the treatment of the disease and establish that the drug has the potential to provide relevant advantages or a major contribution to patient care over existing therapies. The opinion letter sent to Trovagene by the COMP stated that "although satisfactory methods of treatment of the condition have been authorized in the EU, PCM-075 will be of significant benefit to those affected by AML."
The COMP, a committee of the EMA, adopts an opinion on the granting of orphan drug designation, after which the opinion is submitted to the European Commission for endorsement of the opinion. The positive opinion issued by the COMP is anticipated to be adopted by the European Commission (EC) at the end of August 2018.
Orphan drug designation by the European Commission provides regulatory and financial incentives for companies to develop and market therapies to treat a life-threatening or chronically debilitating condition affecting no more than five in 10,000 persons in the European Union (EU), and where no satisfactory treatment is available. Among the incentives available to therapeutics designated as orphan drugs by the EC are ten-year market exclusivity in the EU after product approval, eligibility for conditional marketing authorization, protocol assistance from the EMA at reduced fees during the product development phase and direct access to centralized marketing authorization in the EU.
About Acute Myeloid Leukemia (AML)
Acute myeloid leukemia (AML) is an aggressive 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 incidence is estimated to be approximately 18,000 new cases annually in the EU and is on the rise due to the aging population. The five-year survival rate is approximately 22%.
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. 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 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. 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 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 with AML. Trovagene is enrolling a Phase 2 trial of PCM-075 in combination with Zytiga® (abiraterone acetate) and prednisone in metastatic Castration-Resistant Prostate Cancer that was accepted by the National Library of Medicine (NLM) and is now publicly viewable on www.clnincaltrials.gov. The NCT number assigned by clinicaltrials.gov for this study is NCT03414034.
PCM-075 only targets the PLK1 isoform (not PLK2 or PLK3), is orally available, 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 PLK1 inhibitor, PCM-075, with other compounds has the potential for improved clinical efficacy in Acute Myeloid Leukemia (AML), metastatic Castration-Resistant Prostate Cancer (mCRPC), Non-Hodgkin Lymphoma (NHL), Triple Negative Breast Cancer (TNBC), as well as other hematologic and solid tumor cancers.
