/R E P E A T -- Sirona Biochem's TFC-1067 Demonstrates Superiority to Hydroquinone for the Treatment of Dyschromia/

VANCOUVER, April 10, 2019 /CNW/ - Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) (the "Company") is pleased to announce the results of its clinical trial performed by Dr. Zoe Draelos of Dermatology Consulting Services, conducted in North Carolina, USA. Sirona's TFC-1067 demonstrates superiority to the gold standard, hydroquinone, for the treatment of dyschromia (hyperpigmentation or "dark spots" of the skin).

In the 12-week double blinded study involving 48 participants, TFC-1067 successfully achieved the endpoint of lightening dyschromic areas on the skin. With application of TFC-1067, areas of hyperpigmentation were significantly lightened and blended into surrounding skin, evening skin tone while preserving overall tone. TFC-1067, achieved this goal, while the hydroquinone comparator did not.

No clinical safety issues were observed with TFC-1067 during the trial. Combined with extensive preclinical safety testing, there is now strong evidence that TFC-1067 is a safe and superior replacement to hydroquinone for the treatment of facial hyperpigmentation.

Hydroquinone has remained the gold standard for skin lightening despite known toxicity which is an ongoing concern for the FDA and the dermatology community. Hydroquinone is banned or has restricted dosing in an increasing number of countries. Although many non-hydroquinone alternative lightening compounds are either toxic or ineffective, unfortunately, millions of people still resort to toxic treatments for hyperpigmentation despite poor aesthetic results. There is a clear unmet need for a safe and effective treatments in this 20-Billion-USD skin lightening market.¹

The Company is currently pursuing publication of these results in a peer reviewed scientific journal. A detailed report of the clinical trial will then be made available to the scientific community including the dermatological and cosmetic community.

"Having demonstrated clinically in our human trial what we predicted in preclinical testing is further validation of the commercial value of our proprietary technology," reports Dr. Howard Verrico, CEO Sirona Biochem. "These results were achieved with a very basic formulation. The full potential of TFC-1067 is yet to be demonstrated. Having validated the commercial value of TFC-1067 with the clinical trial's success we have greatly improved our licensing opportunities and value globally. Currently we are in discussions for licensing TFC-1067 in specific markets. An update will be released when these discussions conclude."

"TFC-1067 performed remarkably well in comparison to 2% hydroquinone, which traditionally has been challenging to approximate. Hydroquinone alternatives are needed," said Dr. Zoe Draelos. "Most consumers desire lightening of dark spots to blend into surrounding skin. The study product achieved this goal."
