Bringing FDA-approved NGS tests to the masses

Published in Drug Discovery News

SAN DIEGO—Expanding applications of its recently FDA-approved MiSeqDx in-vitrodiagnostic next-generation sequencing (NGS) system, Illumina has agreed to help develop a multigene, NGS-based test to identify prospective patients for Vectibix (panitumumab), an anti-EGFR monoclonal antibody drug developed by Amgen, a drug company based in Thousand Oaks, Calif.
 
“This collaboration is consistent with our strategy to bring the power of NGS to clinical diagnostics,” said Nick Naclerio, senior vice president of corporate and venture development and general manager of Illumina's Enterprise Informatics business. “With three FDA-cleared NGS products in our portfolio, we intend to complement internal development programs by taking products developed with external partners through the FDA submission process. Amgen is a key partner given their leadership in therapeutic development and strong track record in commercializing novel products.”
 
“NGS provides an advantage over traditional technologies that typically detect only one or a few variants,” added Dr. Rick Klausner, chief medical officer and acting general manager of Illumina’s oncology business. “Multigene NGS panels provide a more complete genetic picture of each patient's tumor, which can better inform critical treatment decisions. We see the development of multigene diagnostic tests as a natural evolution to improve cancer care and outcomes.”
 
Vectibix has regulatory clearance in the United States and the European Union for targeting metastatic colorectal cancer that has not responded to chemotherapy.
 
At present, Illumina has just three tests available for the MiSeqDx instrument, which uses the sequencing-by-synthesis method of assaying. There is a universal kit allowing researchers to make their own tests, and two tests for assaying genes connected with cystic fibrosis. MiSeqDx’s November 2013 FDA approval makes it the first NGS platform with that imprimatur. To build on that achievement, market analysts report that the company has eagerly sought partnerships like the new one with Amgen.
 
Using the Illumina platform, the test to be developed could solve a key problem Amgen has with Vectibix: the drug is aimed at less-aggressive forms of the cancer and is restricted for patients who have, or do not know whether they have, KRAS mutations, which are associated with more aggressive cancers and lower survivability. But there is not yet an FDA-approved test to determine KRAS mutation status for potential Vectibix patients.
 
According to a report on GenomeWeb.com, Amgen is also working with Dutch-headquartered QIAGEN to develop a polymerase chain reaction kit to detect KRAS mutations that might affect Vectibix’s usefulness. The financial details of that deal are not being made public.
 
The Illumina test would not only use NGS technology, but would also detect RAS oncogene mutations beyond just those in KRAS.
 
“We believe the NGS platform offers great market potential,” reads a report from Zacks Investment Research, which also says the analysis firm is “optimistic about management’s expansion strategy,” which involves working with diagnostic and therapeutic developers and providers. In January alone, the company announced agreements with both Quest Diagnostics and LabCorp, with Illumina providing equipment and supplies for its partners to develop new lab tests.
 
Under the terms of the Vectibix deal, Illumina will develop the test, which will be validated by Amgen. Then both companies will work to get FDA and European approval, before Illumina commercializes the test.
