Sirona Biochem Receives Positive Safety Data for Lead Skin-Lightener in Preparation for Clinical Trial in the US

VANCOUVER, British Columbia , Sept. 26, 2018 (GLOBE NEWSWIRE) -- Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) (Xetra: ZSB) (the “Company”) is pleased to report further progress regarding the clinical development of its lead skin-lightener, TFC-1067.

In parallel with ongoing partnering discussions, Sirona has completed steps toward the clinical trial for TFC-1067. A toxicologist, from CEHTRA in Paris, was hired to approve Sirona’s compound for clinical use. From the pre-clinical data, the toxicologist established a clinical dose for the compound and further confirmed that it does not degrade into toxic metabolites such as hydroquinone and benzoquinone.

The Company also contracted formulation expert Gael Boutry of Global Beauty Consulting in France to develop a formulation acceptable for clinical use. The formulation (face cream) containing TFC-1067 has already been prepared, packaged and tested in an accelerated stability test to ensure shelf-life.

Over the past two months, safety studies with the formulation have been ongoing at Dermscan, Poland, and continue to provide positive data for TFC-1067. The first study, a human patch test on 10 people, confirmed TFC-1067 as a non-irritant, in contrast to many other skin-lighteners.  

In early August, a second clinical trial for the Human Repeat Insult Patch Test (HRIPT) which assesses sensitization on a larger group (110 people) began, in preparation for future efficacy trials. Initial results from the panel show TFC-1067 as a non-sensitizer. With these tests completed, Sirona will begin their proof of efficacy clinical trial in October, at a center in the United States, led by an acclaimed dermatologist.

“The significance of the data that supports the formulated TFC-1067 cream as a non-irritant, non-sensitizer cannot be understated, as many common skin-lighteners, like hydroquinone, resorcinol, and Kojic Acid, have known toxicities at effective doses,” said Dr. Howard Verrico, CEO of Sirona Biochem. “The market has an unmet need with the safety and efficacy problems associated with the currently available skin lighteners and we are confident that TFC-1067 will meet this need. With an inventory of formulated product, we are primed to start the trial in October.”

The planned clinical trial does not prevent negotiations of a definitive agreement in the interim. Advancing the development continues to add value to TFC-1067 and shorten the time to full commercialization. This improves our future potential partners ability to share our confidence in the commercial opportunity we are creating. In parallel, meetings with North American and Asian cosmetic companies continue to move forward.
