Guided Therapeutics, Inc. (OTCBB: GTHP) (OTCQB: GTHP) today announced that it has received notification from the U.S. Food and Drug Administration (FDA) regarding the pre-market approval (PMA) application for the LuViva® Advanced Cervical Scan. In its most recent communication, FDA advised the Company that its PMA amendment, filed in July 2014, was not approvable in its current form. While the agency advised the Company that more patient data would likely be necessary to amend the current application, the agency also stated its willingness to consider alternative approaches to move the product to approvable form.

FDA and the Company intend to meet to discuss the plan for submission of an updated amendment and ultimately reach agreement on steps forward for a path to approval to resolve any remaining data analysis issues. At this meeting, the Company intends to present additional U.S. and international data that the Company believes will further support the clinical benefits of LuViva.

“We believed our PMA amendment addressed the remaining questions the agency had about our original application,” said Gene Cartwright, Chief Executive Officer of Guided Therapeutics. “At the current time, however, we believe the best and fastest way to secure approval may be to collect data on additional subjects and then file an amendment to further demonstrate LuViva’s safety and effectiveness as a triage device after an abnormal HPV test or Pap test. While we are disappointed the data analysis issue was not fully resolved, we are encouraged that no other remaining or new issues were raised in the FDA letter.

“We are confident we will eventually receive approval to market LuViva in the U.S. and will provide more detail once we meet with FDA to determine what our pathway to approval will be. In the meantime, we continue to add to the growing number of doctors successfully using LuViva in the much larger international market and have significant momentum building, particularly where our product is being considered for screening. In 2015 we expect our sales to grow significantly, with orders from Turkey and Kenya driving our near term results,” said Mr. Cartwright.

The Company currently has regulatory approval to sell LuViva in Europe with the Edition 3 CE mark, and has marketing approvals from COFEPRIS in Mexico, Health Canada and Singapore Health Sciences Authority, among others. Additionally, expansion efforts are ongoing in the Middle East, Asia and Latin America.

About LuViva® Advanced Cervical Scan

LuViva is a technologically advanced diagnostic device that scans the cervix with light and uses spectroscopy to measure how light interacts with the cervical tissue. Spectroscopy identifies chemical and structural indicators of precancer that may be below the surface of the cervix or misdiagnosed as benign. This technique is called biophotonics. Unlike Pap, HPV tests or biopsies, LuViva does not require laboratory analysis or a tissue sample, and is designed to provide results immediately, which may result in eliminating costly, painful and unnecessary additional testing. LuViva is intended for use with women who have undergone initial screening and are called back for follow up with a colposcopy examination, which in many cases, involves taking a biopsy of the cervix. It has also been used in clinical studies in Turkey and Nigeria as a means to screen women for cervical cancer where the availability of infrastructure necessary for Pap and HPV testing is restricted. The device is used in conjunction with the LuViva® Cervical Guide single-use patient interface and calibration disposable.
