Personal Genome Diagnostics Study Highlights Limitations of Tumor-only Sequencing for Cancer

Personal Genome Diagnostics, Inc. (PGDx), a provider of advanced cancer genome analysis and testing services, recently announced the publication of a landmark study showing that many of the genetic alterations identified using tumor-only sequencing are not actually associated with the cancer, but instead reflect inherited germline mutations already present in the normal cells of the individual. The study is in the April 15 edition of Science Translational Medicine and was conducted by PGDx scientists working in collaboration with company co-founders Dr. Victor Velculescu and Dr. Luis Diaz, Jr. and their colleagues at Johns Hopkins University.

LabCorp Contributes to Clinical Research Collaborations Directed at Advancing Treatment of Breast Cancer and Viral Hepatitis

Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH) recently highlighted clinical research efforts in oncology and viral hepatitis that demonstrate its commitment to novel diagnostic capabilities and unique bioinformatics resources to enhance patient care in today’s rapidly evolving healthcare system.

Utility Of Rubicon Genomics’ ThruPLEX-FD Kit Validated In Study Showing “Liquid Biopsy” Can Track Genomic Evolution Of Cancer In Response To Therapy

Rubicon Genomics, Inc., a leader in the development and commercialization of innovative sample-specific nucleic acid library preparation products used in research and clinical testing, recently reported that its ThruPLEXTM-FD Prep Kits contributed to the success of a breakthrough study recently published in Nature1 that showed that genomic data extracted from the plasma of cancer patients can be used to track drug resistance and potentially guide treatment.

Almac Offering TruSight Tumor Profiling Next-Generation Sequencing Service

Almac recently announced they are now offering a Tumor Profiling service running Illumina’s next-generation sequencing (NGS) TruSight Tumor™ panel as part of their biomarker discovery, development and delivery solutions.

Almac, a personalised medicine company with CAP accredited and CLIA certified laboratories, extends their portfolio of services by offering TruSight Tumor™ to complement its current range of RNA, DNA and protein based technologies for biomarker analysis.

Almac is currently running many bespoke diagnostic assays for pharma customers for early phase clinical trial enrichment. The TruSight Tumor™ panel enables additional profiling of these patient samples to provide Almac’s pharma partners with further important information on emerging biomarkers that may also impact drug response.
The TruSight Tumor™ panel was developed by Illumina for their MiSeq® system, allowing targeted DNA sequencing and reporting on the mutation status of 26 genes which are most commonly mutated in solid tumors including lung, colon, ovarian, melanoma and gastric cancers.

One of Almac’s key strengths is many years of experience in working with formalin fixed paraffin embedded (FFPE) tissue. The TruSight Tumor™ panel is specifically designed for use with FFPE samples, and enables the highest levels of sensitivity for mutation detection with limited DNA input requirements.

“Almac is committed to the development of personalised medicine through the delivery of a wide range of innovative solutions. We are pleased to announce the expansion of our NGS service to include TruSight Tumor™” said Professor Paul Harkin, President and Managing Director of Almac’s Diagnostic business unit.

NanoString Technologies Receives FDA 510(k) Clearance for Prosigna Breast Cancer Prognostic Gene Signature Assay

NanoString Technologies, Inc., (NASDAQ: NSTG) a provider of life science tools for translational research and molecular diagnostic products, recently announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its Prosigna™ Breast Cancer Prognostic Gene Signature Assay. Based on the PAM50 gene signature, Prosigna is the company’s first FDA-cleared in vitro diagnostic assay and uses the gene expression profile of cells found in breast cancer tissue to assess a patient’s risk of distant recurrence of disease. The Prosigna Assay is performed using the nCounter® Dx Analysis System, which can be placed in qualified laboratories throughout the United States, empowering oncologists and pathologists to quickly and easily meet the testing needs of their breast cancer patients.

“Receipt of FDA 510(k) clearance for Prosigna marks a key milestone for NanoString and is an important step forward in the treatment of breast cancer. This achievement is a testament to the ongoing dedication and professionalism of our team, and the commitment of our collaborators,” said Brad Gray, President and Chief Executive Officer of NanoString Technologies. “Prosigna illustrates our approach of using nCounter technology to translate genomic discoveries into powerful in vitro diagnostic products, and it represents a significant growth opportunity beyond our robust life sciences research business.”

The Prosigna Assay is intended for use as a prognostic indicator for distant recurrence-free survival at 10 years, and is indicated for postmenopausal women with Stage I/II lymph node-negative or Stage II lymph node-positive (one to three positive nodes) hormone receptor-positive breast cancer who have undergone surgery in conjunction with locoregional treatment consistent with standard of care. For each patient, the Prosigna Assay reports the Prosigna Score (referred to as Risk of Recurrence Score, or ROR Score, in the scientific literature, including the TransATAC study recently published in the Journal of Clinical Oncology ) and a risk category based on both the Prosigna Score and nodal status. Node-negative patients are classified as low, intermediate or high risk, while node-positive patients are classified as low or high risk.

Other key features of the Prosigna Breast Cancer Prognostic Gene Signature Assay include:

  • All-in-one assay consumables, including RNA extraction kits, allowing laboratories to test as little as a single section of formalin-fixed paraffin embedded (FFPE) tumor tissue
  • High-throughput workflow allowing each nCounter Dx Analysis System to process up to 30 patient samples per eight hour work day
  • Automated generation of personalized full-color patient reports that can be quickly and easily shared electronically with ordering oncologists

Bruce Seeley, Senior Vice President & General Manager of Diagnostics of NanoString Technologies commented: “We believe that the compelling clinical data, clear patient reporting, and unique delivery model position Prosigna for success in the U.S. market. By integrating the Prosigna Assay into existing laboratory workflows, we are offering physicians and patients seamless and timely access to clinical insights and a powerful tool that can aid in making more informed treatment decisions.”

Prosigna-enabled nCounter Dx Analysis Systems are expected to be available for placement in high-complexity Clinical Laboratory Improvement Amendments (CLIA) certified laboratories late in the fourth quarter of 2013. Prosigna testing services are expected to be available through qualified U.S. clinical laboratories beginning in the first quarter of 2014.
