Trovagene's Urine-Based Liquid Biopsy Platform Shown to Detect Impact of Cancer Therapy within 24 Hours
Clinical Data to be Presented in Oral Session on Liquid Biopsies at the 16th World Conference on Lung Cancer

SAN DIEGO, Sept. 9, 2015 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a developer of cell-free molecular diagnostics, announced today that clinical data featuring its Precision Cancer Monitoring℠ platform will be presented at the 16th World Conference on Lung Cancer in Denver, Colorado. Hatim Husain, M.D., University of California, San Diego School of Medicine will present the results in Oral Session 38: Liquid Biopsies. The data highlight the ability to monitor real time response to targeted therapy.

A molecular diagnostics company with unique intellectual property around the discovery that DNA and RNA, present in urine, can be diagnostic of cancer and infectious disease.

"We have been able to model some of the early effects of chemotherapeutic agents on patients to model tumor lysis," stated Dr. Husain. "In this expanded data set, we were able to closely monitor the dynamic changes in urinary EGFR mutation load at initial therapy, recurrence, and in retreatment scenarios."

Dynamic Changes in EGFR Mutation Circulating Tumor DNA in Urine on Anti-EGFR Therapy Presenter: Hatim Husain, M.D., University of California, San Diego Moores Cancer Center.

Presentation Highlights:

  • Urine has been shown to be a viable specimen type for cancer monitoring using liquid biopsy and offers the unique ability to track tumor dynamics in lung cancer patients
  • Early peaks observed for EGFR Exon19 Deletion, L858R, and T790M mutations in urinary ctDNA collected daily on days 1-4 within the first weeks of next-generation anti-EGFR TKI treatment correlated with radiographic response or lack of response 6 weeks after first drug dosing.

About The T790M Mutation in Non-Small Cell Lung Cancer

While lung cancer is one of the most aggressive malignancies, progress has been made in the advancement of therapeutic strategies against the disease. In particular, epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), such as gefitinib and erlotinib, in non–small cell lung cancer (NSCLC) patients with EGFR mutations have demonstrated clinical response rates as high as 80%. However, after about 6 to 12 months, most tumors develop acquired resistance to these targeted therapies. Research into such resistance has identified the secondary T790M mutation, which occurs in approximately 60% of patients with acquired resistance to EGFR-TKIs and is reported to negate the benefits of treatment. To date, no effective treatment options have been approved for NSCLC patients with the T790M mutation, however new targeted drug candidates such as rociletinib and AZD9291 are in advanced clinical development, and have shown promise for this indication.

About the World Conference on Lung Cancer

The World Conference on Lung Cancer is the world's largest meeting dedicated to lung cancer and other thoracic malignancies. More than 7,000 delegates from over 100 countries attend the conference to discuss the latest developments in thoracic malignancy research. Attendees include surgeons, medical oncologists, radiation oncologists, pulmonologists, radiologists, pathologists, epidemiologists, basic research scientists, nurses, allied health professionals, patients and patient advocates.
