HER2 Gene Amplification Test Will Aid in Assessing Breast Cancer Patient Candidacy for Herceptin(R) Treatment
CARLSBAD, Calif., Jul 08, 2008 (BUSINESS WIRE) -- Invitrogen Corporation, (NASDAQ:IVGN), a provider of essential
life science technologies for research, production and diagnostics,
today announced it has received U.S. Food and Drug Administration
(FDA) premarket approval (PMA) for its SPOT-Light(R) HER2 CISH Kit,
indicated as an aid in the assessment of breast cancer patients for
whom trastuzumab (Herceptin(R)) treatment is being considered. The
approval marks the first PMA that Invitrogen has received from the
FDA.
"The introduction of the SPOT-Light(R) HER2 CISH Kit is another
example of how Invitrogen technologies can be used in a clinical
setting to have a direct impact on healthcare," said Greg Lucier,
Chairman and Chief Executive Officer of Invitrogen. "The FDA's
approval of this kit for the U.S. market also demonstrates our ability
to apply Invitrogen technologies into high-growth applied markets."
The kit is based on a technology called chromogenic in situ
hybridization (CISH). The test uses a DNA probe for the HER2 gene,
which is amplified in 18 to 30 percent of breast cancers and predicts
whether a breast cancer patient is a candidate for trastuzumab
treatment. Current medical practice requires that all patients who are
considered for trastuzumab treatment be tested for HER2 amplification
or overexpression. CISH test results are visualized under a standard
bright-field microscope, as opposed to fluorescent in situ
hybridization tests, in which the results must be visualized using a
fluorescent microscope. This specialized microscope frequently
requires that the analysis is done at a reference lab. In addition,
HER2 CISH test results are quantifiable; removing the subjectivity
inherent in tests based on immunohistochemistry (IHC) interpretation
schemes.
"The current protocol for assessing HER2 gene status is for labs
to initially screen tissue samples with immunohistochemistry to gauge
whether there is an overabundance of the HER2 protein, as an indirect
measure of gene amplification," said August Sick, vice president and
general manager of Invitrogen's Cellular Analysis Business. "In the
case of an inconclusive test, the samples are typically sent to an
outside lab for confirmation. Because the SPOT-Light(R) HER2 CISH Kit
doesn't need specialized equipment, any histology lab can now assess
amplification of the HER2 gene while simultaneously examining tissue
morphology."
"Given the emerging potential use of trastuzumab in the adjuvant
setting, the need to accurately determine the front-line HER2 status
in breast cancer has never been more critical," said Jeffrey Ross,
M.D., Cyrus Strong Merrill Professor and Chair, Department of
Pathology and Laboratory Medicine, Albany Medical College. "The CISH
method has shown a high concordance with fluorescent in situ
hybridization (FISH)-based assays for the identification of HER2 gene
amplification, now considered the standard for confirming eligibility
to receive the drug. Testing for HER2 status in breast cancer by CISH
takes advantage of the best attributes of FISH using familiar, fast
and low cost IHC detection techniques. This is a true marriage between
the two procedures."
The SPOT-Light(R) HER2 CISH Kit will be available in the U.S. in
mid-August.
