Communicators

 Vancouver, Canada – October 6, 2021 – Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) (OTC: SRBCF) (“Sirona”) is pleased to provide the following Q3 update to shareholders.

Dear shareholders,

We are providing this quarterly update with a particular focus on our TFC-1067 compound for skin lightening as it advances towards a second commercial license agreement.

The individual project updates are as follows:

TFC-1067

North America

As previously reported, our second clinical trial for TFC-1067 was supported by a top 10 pharmaceutical company, which included the right to complete due diligence in the months following. Our partner has successfully completed their analyses of the compound and we have moved into the next stage of licensing discussions. A global license with a highly respected partner is our preferred outcome for TFC-1067.

Rodan + Fields (R+F) continue sales of the add-on product, REVERSE Targeted Dark Spot Corrector which contains TFC-1067 as the active ingredient. R+F orders for raw material have been forecast for the remainder of 2021.They remain an excellent partner, successfully advancing the commercial use of TFC-1067 in their product. A first for Sirona.

Our manufacturing partner, WuXi AppTec has prepared an inventory of TFC-1067 that will be held in storage in China. This inventory will allow for zero delays in requests for orders as we move forward with anticipated partnerships. We are also maintaining manufacturing capabilities in France and exploring new manufacturing processes as we continually evolve our platform technology for this and all projects.

We believe, based on safety and efficacy data, that we possess the industry leading compound for lightening dark spots and balancing skin tone. We are confident TFC-1067 will have a strong commercial future.

Asia

Our business strategy for Asia continues to evolve due to challenging regulatory requirements. We will still advance and offer a second compound, TFC-1394, from our patented library for countries that have differing needs. Having either a global or regional partner will be critical to navigate commercialization in China and other Asian countries. With advanced discussions ongoing for a global license, we will scale back pursuing regional opportunities.

TFC-039

Human Diabetes

Wanbang Biopharmaceuticals has completed Phase I studies for diabetes drug candidate TFC-039 and is currently in the data analysis phase. We are awaiting further information for their plan to move forward. Some logistical challenges have caused delays and we will update shareholders as soon as we have material information on the project.

Animal Health

We have received clinical data from the cat studies which show TFC-039 to be safe and well tolerated. There is concern regarding manufacturing and the final cost of goods which are not yet fully defined. Our team is addressing this challenge with assistance from Wanbang and we have their full commitment.

Other Indications

The team at TFChem is investigating further indications for TFC-039 and have identified target diseases. We are putting in place the contract research organizations to evaluate these targets as well as developing the patents.

Anti-Aging

The lead compound from our anti-aging library is advancing to scale-up. This first batch will be developed for stability testing, formulation, and the clinical study. Preliminary results for some studies will be available in Q4 of 2021, however, due to the need to keep information confidential while patents are being written, only select information will be released.

Discussions with potential partners remain preliminary.

Antiviral

Our team in France has synthesized 16 novel antiviral compounds for testing. Information is currently limited as we develop IP around these compounds. We are encouraged by the recent successful Phase 3 clinical trial of a new antiviral from Merck & Co in the treatment of COVID-19 (Merck pill seen as 'a huge advance', raises hope of preventing COVID-19 deaths | Reuters).

Anti-Cellulite

Our recently announced discovery of a potential cellulite therapy is still in early-stage development. This discovery represents another major market opportunity for our company and has already garnered interest from a global pharmaceutical company.

Financing

Sirona’s last private placement financing was over 2 years ago, a similar financing is not being planned. Management will execute a strategy which will include non-dilutive sources.

With the completion of the due diligence of our top 10 global pharma partner, a decisive phase is approaching. While our scientists in France are making excellent progress in advancing our pipeline, management is fully focused on closing concrete agreements and sustainably increasing shareholder value.
