TSO3 Provides Duodenoscope Regulatory Filing Update

QUEBEC CITY and MYRTLE BEACH, SC, Nov. 16, 2017 /PRNewswire/ - TSO3 Inc. (TSX: TOS), an innovator in sterilization technology for medical devices in healthcare settings, announced today that it has responded to the recent request for additional information (AI), from the U.S. Food and Drug Administration. This information is in support of the Company’s submission to extend claims of its innovative STERIZONE^® VP4 Sterilizer to include terminal sterilization of duodenoscopes.

The Company’s response includes a summary of results from tests evaluating the effect of TSO₃‘s sterilization process on specific features incorporated in the design of identified scopes, as well as additional labeling targeted at a selected duodenoscope. Lastly, in its response, the Company defined recommended device inspection and use intervals to assist end-users in their instrument surveillance when performing terminal sterilization of duodenoscopes within the STERIZONE^® System.

“Our team has done an exemplary job of quickly addressing the questions and comments received from US regulators in September,” stated R.M.(Ric) Rumble, TSO₃‘s President and CEO. “In anticipation of receiving our response, a call to review the submission has already been discussed with the agency to address any additional changes or modifications to the suggested labeling in the response. The attention the file is getting is very positive and the Company continues to aggressively pursue all avenues for a final and favorable review this year.”

About the STERIZONE^® VP4 Sterilizer

The STERIZONE^® VP4 Sterilizer is a low-temperature sterilization system that utilizes the dual-sterilants of vaporized hydrogen peroxide (H₂O₂) and ozone (O₃) to achieve terminal sterilization of heat and moisture sensitive medical devices. Its single pre-programmed cycle can sterilize a large number and wide range of compatible devices, creating a cost-effective sterilization process with error free cycle selection. The device’s unique Dynamic Sterilant Delivery System™ automatically adjusts the quantity of injected sterilant based on the load composition, weight and temperature. This capability removes the guesswork and potential for human error, as there is no need to sort instruments and choose the appropriate cycles as with other machines.

The STERIZONE^® VP4 Sterilizer is the only terminal sterilization method that is FDA cleared to sterilize multi-channeled flexible endoscopes (with a maximum of four channels) of up to 3.5 meters in length, such as video colonoscopes and gastroscopes - an industry first for any medical device sterilization process.

The STERIZONE^® VP4 Sterilizer is also the only cleared low temperature sterilizer that can process a mixed load consisting of general instruments, single channel flexible endoscopes, and single or double channel rigid endoscopes in the same cycle with load weights of up to 75lbs. The ability to run mixed loads significantly reduces labor costs by minimizing the amount of instrument sorting required, while maximizing the device turns (more productivity from increased throughput capacity).
