Guided Therapeutics, Inc. (GT) (Pink Sheets: GTHP) today announced that its LightTouch™ non-invasive cervical cancer detection technology properly identified cervical disease missed by Pap tests and conventional pathology in a multi-site Food and Drug Administration (FDA) pivotal clinical trial. Based on the outcome of the study, GT plans to submit the trial results to the FDA as part of the Premarket Approval (PMA) application for the LightTouch.

"We are very pleased that the results of the study indicate that the LightTouch is capable of discovering disease that may be missed by conventional cervical disease detection," said Mark L. Faupel, Ph.D., GT President and CEO at the Southeastern Medical Device Association annual conference in Atlanta. "Based on the study results, we believe that our technology also demonstrates the capability to detect cervical disease early, when it is most effectively treated."

Since the pivotal trial began, more than 1,900 women were tested to demonstrate the technology's safety and efficacy in detecting cervical disease, including an arm of the study that assessed effectiveness of an investigational commercial version of the device and single-use disposable.

The study protocol indicated that all subjects were referred after undergoing a Pap test, or had some other risk factor that fulfilled the referral criteria of the study. Each subject was tested with the LightTouch investigational device and underwent an additional Pap test, colposcopic exam and biopsy. Two generations of the investigational LightTouch were used in the trial.

Preliminary results from the study showed that the LightTouch performed better than the Pap test…
