Matritech’s NMP22® BladderChek™ Test

Matritech’s NMP22® BladderChek® Test , approved by the FDA for the diagnosis and monitoring of bladder cancer as of Feb. 2005.

About Matritech:
Matritech is using its patented proteomics technology to develop diagnostics for the detection of a variety of cancers. The Company’s first two products, the NMP22® Test Kit and NMP22® BladderChek® Test, have been approved for the monitoring and diagnosis of bladder cancer. The NMP22 BladderChek Test is based on Matritech’s proprietary nuclear matrix protein (NMP) technology, exclusively licensed from the Massachusetts Institute of Technology, which correlates levels of NMPs in body fluids to the presence of cancer. The Company has discovered other proteins associated with cervical, prostate, breast and colon cancer and is, with its own research staff and through strategic alliances, in various stages of development targeted to each of these applications.

The two JAMA articles cited above have created a media hype hardly ever seen in the world of bladder cancer diagnostics or treatments. However, there have been at least two critiques published in January 2006, that question the interpretation of the trial results:

"…This study neither reports the full data nor a comprehensive data analysis. The conclusions that the NMP22 test should be recommended are therefore not substantiated and seem questionable when a test achieves a sensitivity of 56% at the price of a false positive rate of 80%…."

_UK summary for patients and professionals: Evaluation of the evidence base for the detection of bladder cancer using a point-of-care proteomic assay. Excerpt:
"…The main conclusions of the study focussed on the finding that the NMP22 assay had significantly greater sensitivity (56%) than cytology (16%). While this is true, it is important to note that even the NMP22 assay still missed 44% of bladder cancers detected by the reference standard of cystoscopy. These results suggest that neither urine test alone would be useful in ruling out a diagnosis of bladder cancer. This is particularly important since the main clinical role for non-invasive tests of this type is usually seen as ruling out disease and thus reducing the number of patients requiring invasive, confirmatory examinations…"
