Nuclea Bio Acquires Oncogene Science, Extends Deal with Wilex

Just a few months after announcing several new partnerships and landing venture capital dollars, Nuclea Biotechnologies Inc. has snapped up Oncogene Science, an Cambridge, Mass.-based subsidiary of Wilex AG in Germany.

The Ongoing Collaboration Aims to Exploit the High Throughput, Robustness and Ease of Use of MALDI-TOF Instruments

At the 12th HUPO World Congress, Bruker Corporation (NASDAQ: BRKR) recently announced the start of a second-phase collaboration agreement with SISCAPA Assays Technologies, Inc. (SAT). The ongoing collaboration aims to exploit the high throughput, robustness and ease of use of MALDI-TOF instruments as an alternative to nano-LC-MS technology currently used in many SISCAPA assays.

Ventana Receives Approval from China’s FDA for First Fully Automated IHC Companion Diagnostic Identifying ALK Protein Expression in Lung Cancer Patients

Ventana Medical Systems, Inc. (Ventana), a member of the Roche Group, recently announced the approval of the VENTANA ALK immunohistochemistry (IHC) assay by the Chinese Food and Drug Administration (CFDA) as a companion diagnostic to aid in the identification of patients for Pfizer’s CFDA-approved oncology product XALKORI® (crizotinib). The VENTANA ALK (D5F3) Rabbit Monoclonal Primary Antibody assay is designed to identify ALK-positive patients in non-small cell lung cancer (NSCLC) patients1. The approval is based on a retrospective study that included 1100 Chinese subjects across three national hospitals where the VENTANA assay demonstrated 99.23 percent concordance with Abbott’s Vysis ALK Break Apart FISH Probe Kit.

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.
