Guided Therapeutics Files Premarket Approval Application Clinical Report with FDA

Guided Therapeutics, Inc. (OTCQB: GTHP), the maker of the LuViva Advanced Cervical Scan, a rapid and painless testing platform for cervical cancer detection based on its patented biophotonic technology, announced today it had filed the results of its multicenter clinical trial with the U.S. Food and Drug Administration (FDA).

The study protocol was developed through interactions with FDA and enrolled 480 women referred to biopsy because of abnormal Pap and/or HPV tests. Of the 428 women that completed the study, 99 were determined by expert independent pathology to have significant cervical disease that can lead to cancer, and of these, 32 cases of disease (32.3%) went undetected by the current standard of care consisting of colposcopy-directed biopsy. The primary goal of the study was to show that LuViva could detect a significant number of these “missed” precancerous lesions.

The results showed that LuViva detected 21 of the 32 (66%) disease cases that were missed by the current standard of care, increasing the detection rate from 68% without LuViva to 89% with LuViva. Moreover, all primary and secondary endpoints regarding the sensitivity and specificity of LuViva were met with a high degree of statistical certainty (p < 0.0001). There were no safety issues or adverse events related to LuViva reported among the study participants.

“The study results exceeded expectations and demonstrate that LuViva has the potential to address an important clinical need in a highly impactful way,” said Guided Therapeutics President and CEO Mark Faupel. “We look forward to FDA’s review of the study results and working with our physician team to publish them in a prestigious medical journal.”
