FDA Grants Breakthrough Device Designation to the Prescient Metabiomics LifeKit® Prevent Test for the Early Detection of Colon Polyps and Colon Cancer

On September 4, 2019 Prescient Metabiomics, a privately held company and a subsidiary of Prescient Medicine Holdings, Inc., announced that the U.S. Food and Drug Administration (FDA) has granted the company’s submission for Breakthrough Device designation to its LifeKit Prevent Colorectal Neoplasia Test (Press release, Prescient Metabiomics, SEP 4, 2019, View Source [SID1234539290]). This Breakthrough Device designation is the first designation for a non-invasive diagnostic test that is designed to detect pre-cancerous polyps, as well as early-stage carcinomas, with the potential to aid in the interception of carcinogenesis and prevention of colorectal cancer (CRC). In contrast, other non-invasive tests on the market primarily detect full-blown cancer, not precancerous adenomas, and require programs that rely heavily on colonoscopies to achieve colon cancer prevention.

The LifeKit Prevent Test deploys patented metagenomics technologies intended to identify microbial DNA and RNA biomarkers that are associated with neoplasia in the lower gastrointestinal tract. Using a non-invasive collection swab, the microbial biomarkers in the stool are analyzed. A positive result indicates the presence of colorectal adenomas or CRC, which should be followed by a diagnostic colonoscopy and polypectomy as appropriate.

A "Breakthrough Device" is an important designation by the FDA because it expedites the review process for medical devices that meet the designation criteria and offers more effective diagnosis of life-threatening diseases and conditions. The Breakthrough Device Program (BDP) offers manufacturers an opportunity to engage with the FDA’s experts to efficiently address topics during the pre-market review phase. Prescient Metabiomics anticipates that FDA support through the BDP will greatly reduce the regulatory timeline required for completing clinical trials and achieving FDA clearance.

"We are excited to deliver LifeKit Prevent, a non-invasive diagnostic test that not only will aid in detecting CRC, but also help identify patients at risk for advanced adenomas. By identifying patients most at risk for precancerous lesions, we can stop cancer before it starts and save lives," says Keri Donaldson, MD, and Chief Executive Officer of Prescient Medicine Holdings, Inc. "This important innovation, developed on our robust R&D and machine learning platforms, will allow more targeted and effective treatments earlier. The FDA’s decision confirms the unique aspects of our technology and the potential benefit of our test in addressing the large and increasing population of people at risk of developing CRC."

About Colon Cancer and LifeKit Prevent

Colorectal cancer (CRC) is the third-most common type of cancer and the second leading cause of cancer death in the United States, with over 137,000 new cases and 56,000 deaths annually. The U.S. spends $14 billion each year for the diagnosis and treatment of CRC with costs largely due to delayed detection. While 14 million colonoscopies are performed annually, two-thirds of Americans do not follow screening guidelines and 60 percent of CRC cases are not detected until later stages. Using non-invasive tests to augment colonoscopy has been shown to increase adherence to CRC screening programs. Estimates suggest that broader CRC screening could save 18,800 lives in the US annually.

Previously completed clinical research indicates that LifeKit Prevent may be more convenient for patients and healthcare providers to use than currently available CRC diagnostic tests. Based on current findings, LifeKit Prevent is highly accurate for detecting colon cancer and, more importantly, for detecting precancerous adenomas that are missed by existing non-invasive tests. A positive result from LifeKit Prevent will provide a stronger case to motivate reluctant, high-risk patients to undergo a colonoscopy resulting in the removal of precancerous adenomas to prevent further progression to carcinogenesis and reduce the morbidity and mortality of CRC.

Dr. Den is currently an Associate Professor of Radiation Oncology, Cancer Biology, and Urology at Thomas Jefferson University, who specializes in radiation oncology and co-leads the Sidney Kimmel Cancer Center Multidisciplinary Genitourinary Clinic. Dr. Den’s research has spanned the basic science, translational, and clinical spectrum with over 120 publications and funding from the Prostate Cancer Foundation, American Cancer Society and United States Department of Defense. He has designed and completed several clinical trials incorporating novel agents with radiation therapy. He currently serves as the Chair for the Data Safety and Monitoring Committee and is a member of the Institutional Review Board.

"I envision alpha emitting radiation-based therapy being employed across multiple malignancies, either as primary therapy or in conjunction with immuno-oncology treatments. We have only scratched the surface of the potential indications for this technology. I am privileged to join the Alpha Tau team and take part in this exciting revolution in radiation oncology," commented Dr. Den. "The prospects for Alpha DaRT are tremendous, and I look forward to helping clinicians around the world unleash its full potential."

Dr. Den attended Yale University, and received his medical degree from Harvard Medical School in 2006. He performed his internship at Massachusetts General Hospital and residency at Thomas Jefferson University. Today, he treats a wide array of tumors, with particular focus on genitourinary and gynecologic malignancies. Dr. Den has vast experience in brachytherapy, developing the High Dose Rate Prostate Cancer Program and initiating Intravascular Coronary Artery Brachytherapy at Thomas Jefferson University.

"I am glad to see leaders in their fields continuing to join Alpha Tau," said Uzi Sofer, CEO of Alpha Tau Medical. "Having Dr. Den leading our medical team will be essential for our clinical efforts, especially as we approach the upcoming initiation of our clinical trials in the US and Canada, and discussions with regulators on a potential marketing approval. Bobby brings a unique mix of medical and clinical expertise that will serve us well as we rapidly expand the base of practitioners providing this potentially life-saving treatment to patients in need."

Alpha DaRT (Diffusing Alpha-Emitters Radiation Therapy) delivers high-precision alpha radiation that is released when radioactive substances decay inside the tumor. The short-range alpha particles effectively kill the cancer cells while sparing the surrounding healthy tissue.

Alpha Tau Medical is currently running clinical trials around the world in metastatic breast cancer as well as skin and head and neck cancer. The company’s first clinical study was recently completed in patients suffering from squamous cell carcinoma of the skin, head and neck. Most of the study patients had been previously treated by either surgery or radiotherapy. The results showed a complete response rate of more than 70%, as well as exceptional statistics on long-term followup.

Clinical collaborations with dozens of leading cancer centers worldwide are in process for the investigation of additional indications, including pancreatic, breast, prostate, gynecological, skin, and head and neck cancers. Collaborating centers include Memorial Sloan Kettering Cancer Center, USA, Montreal University Hospital Center, Canada, Tokyo Medical and Dental University and National Cancer Center, Japan.

Sysmex Inostics Publishes First Feasibility Study of NGS-based Liquid Biopsy to Complement Early Breast Cancer Screening by Imaging

On September 4, 2019 Sysmex Inostics’ novel SafeSEQ next-generation sequencing cell-free DNA technology, investigators from the Biomedical Research Institute of Malaga [(IBIMA)-CIMES-UMA, Malaga Spain] and collaborators reported have published the first pilot study to examine the use of a non-invasive liquid biopsy in early diagnosis of breast cancer (Press release, Sysmex Inostics, SEP 4, 2019, View Source [SID1234539286]). This study was unique in that the ctDNA analyses was performed before any invasive diagnostic procedure or treatment.

The SafeSEQ liquid biopsy technology has shown sensitivity down to five mutant molecules in a background of ten thousand normal ones (or 0.05% mutant allele frequency also known as MAF). Utilizing the genes TP53 and PIK3CA, which are commonly mutated in breast cancer, investigators compared the results of traditional standard-of-care tissue biopsy with those of liquid biopsy to determine the degree to which a highly sensitive assay might complement clinical assessment of disease. Of the 13 mutations detected in 10 of the primary breast cancer patients (out of a total of 29 samples) 8 mutations had a variant allele frequency less than 0.39%.

Comparing tissue to liquid biopsy, eight patients had detectable mutations in ctDNA with concordant results between tissue and plasma. Liquid biopsy testing with SafeSEQ detected an additional three patients with ctDNA mutations that were not present in the tissue. The breast cancer samples with detected ctDNA biomarkers were significantly associated with a lower patient age, a higher tumor size, and higher imaging score (indicating higher likelihood of neoplastic disease).

"We have shown in this study how important a sensitive technology is for early detection of breast cancer, as trace amounts of circulating tumor DNA may be lost by the detection method leading to false-negative results", said Dr. Emilio Alba, senior author of the Biomedical Research Institute of Malaga. "Studies of this kind have not been attempted before due to limitations of the technology, and it is great to see Sysmex Inostics leading the path forward for early detection."

The publication "Detection of TP53 and PIK3CA mutations in circulating tumor DNA using Next-Generation Sequencing in the screening process for early breast cancer diagnosis", was published online in the Journal of Clinical Medicine in August of 2019. View Source
