About the DermaPrecise Product Line 

The DermaPrecise™ Injector is an electronic injection system designed to offer new levels of control over any injection into the intro-dermal and subcutaneous layers for which precision of depth, dose and/or delivery matters. 


About RepliCel's Skin and Tendon Programs 

Both RepliCel’s cell-based skin rejuvenation product (RCS-01) and its cell-based tendon regeneration product (RCT-01) have been the subject of successful phase 1 clinical studies. RepliCel is currently preparing for next-phased clinical testing and commercialization of two cell-based regenerative medicines in Japan. In China, RepliCel’s partner, YOFOTO China Health Company, is currently preparing for phase 2 studies in China of these same therapies in collaboration with RepliCel. 

About RepliCel Life Sciences 

RepliCel is a regenerative medicine company focused on developing cell therapies for aesthetic and orthopedic conditions affecting what the Company believes is approximately one in three people in industrialized nations, including aging/sun-damaged skin, pattern baldness, and chronic tendon degeneration. These conditions, often associated with aging, are caused by a deficit of healthy cells required for normal tissue healing and function. These cell therapy product candidates are based on RepliCel’s innovative technology, utilizing cell populations isolated from a patient’s healthy hair follicles.

The Company’s cell therapy product pipeline is comprised of RCT-01 for tendon repair, RCS-01 for skin rejuvenation, and RCH-01 for hair restoration. RCH-01 has been the subject of successful safety and dose-finding clinical studies and is now the subject of its third clinical study evaluating efficacy for the treatment of male and female hair loss due to androgenetic alopecia. This ongoing study is being funded by Shiseido Company Limited pursuant to a license agreement which has now been terminated but is the subject of an arbitration regarding Shiseido’s rights to the product for Asia. RepliCel maintains the undisputed rights to RCH-01 for the rest of the world. RCT-01 and RCS-01 are exclusively licensed in Greater China to YOFOTO (China) Health Company. RepliCel and YOFOTO are currently co-developing these products in China. RepliCel maintains the rights to these products outside of Greater China.

RepliCel has also developed a proprietary injection device (DermaPreciseTM) and related consumables, which is expected to improve the administration of its cell therapy products and certain other injectables. YOFOTO has exclusively licensed the commercial rights for the DermaPrecise™ device and consumables in Greater China for dermatology applications and is expected to first launch the product in Hong Kong upon it being approved for market launch in either the United States or Europe.

Notable Facts: 

  • RepliCel's three cell therapy products have now been tested in over 100 patients in four countries on three continents. 
  • RepliCel now has key strategic regional partners each of which are now investing heavily in the further clinical testing and development of RepliCel's products for their markets. Data from each of the clinical programs will strengthen the product development initiatives for RepliCel and its other partners worldwide.
