Sequenom, Inc. has announced new positive data from the prospective clinical studies using the Company’s noninvasive SEQureDx™ technology, enabling the detection of fetal aneuploidy from maternal blood.

The data presented consist of 459 new, high prevalence samples from the prospective, blinded studies performed at Sequenom, bringing the total number of samples studied to 858. Based on the results from the total study samples, including samples as early as 8 weeks of pregnancy, the Sequenom SEQureDx RNA-based technology demonstrated a 100% positive predictive value (PPV) and a 99.9% negative predictive value (NPV).

According to Sequenom, the SEQureDx technology achieved a better than 99% detection rate, with less than a 1% false positive rate. The current standard of care, screening tests, perform at less than a 99% detection rate; however, statistically, if these screening tests could perform at a 99% detection rate, their false positive rate would be in the 10% to 25% range. SEQureDx compares favorably to the current invasive procedures, such as amniocentesis.

In addition to data on the RNA-based technology, the Company unveiled a technology which further enhances Sequenom’s SEQureDx technology. This new DNA approach has demonstrated in early studies universal ethnic coverage, high sensitivity and specificity, and the ability to detect Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome) and Trisomy 13 (Patau syndrome) in a single test. This technology is being developed as a “reflex test” for unresolved results from the current SEQureDx Trisomy 21 technology will be available at the time of the launch of the Trisomy 21 laboratory developed test (LDT) in June 2009.
