Sirona Biochem Reports Positive Results in Safety Study for Anti-Aging Compound TFC-1326

VANCOUVER, British Columbia, Nov. 16, 2022 (GLOBE NEWSWIRE) — Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) (OTC: SRBCF) (“Sirona”) is pleased to announce positive results of the clinical safety study for their novel anti-aging compound TFC-1326 1% in formulation, now proven to be a non-irritant and non-sensitizer. TFC-1326, Sirona’s lead anti-aging compound, will soon enter a clinical trial designed to assess its potential to reverse the effects of aging on facial skin, restoring lost volume and reducing fine wrinkles.

The safety study, which was conducted in Europe under the control of a dermatologist, is a Human Repeat Insult Patch Test with Challenge (HRIPT). The main goal of the HRIPT is to confirm that the application of the investigational product (under maximizing conditions of exposure in a panel of healthy human adult subjects) does not induce delayed contact sensitization and secondarily, to assess the skin compatibility of the formulation. TFC-1326 1% in formulation is a non-irritant and non-sensitizer, a claim recognized in the industry based on these results and accepted by global regulatory bodies.

The study population included 100 healthy individuals aged 18-70. Applications were repeated 9-times to the same site (induction site) over a period of 3 consecutive weeks. After a minimal 2-week rest period, with no product application, a single application of the investigational product was placed under a patch to both the induction site and a new site, to reveal a possible induced allergy (challenge phase). In parallel, distilled water is placed under a patch at the same defined times as the investigational product to act as a control site.

Sirona’s anti-aging compound at 1% in the formulation did not cause irritation, sensitization or allergy in any subject.

The results of the HRIPT study are necessary to move to the efficacy clinical trial which remains scheduled to start in early December. A news release will be made announcing the start of the trial and further details will be provided.
