Regulatory Statements for D'OXYVA®

For United States Residents Only



Circularity operates a state-of-the-art supply chain and Quality Management System (QMS) for manufacturing. Circularity has a certificate of registration to IS EN ISO13485:2012 (European Union) and ISO13485:2003 under CMDCAS (Canada) it has been implementing since 2013.


D'OXYVA is a CE-marked medical device (Class I, low risk) for delivery of medications via the skin. Circularity is seeking approvals via the U.S. FDA and in other countries for delivery of Medical Gases such as Medical Carbon Dioxide (USP UN1013) via a novel patented non-invasive transdermal route with D'OXYVA as treatment for various widespread conditions.


Medical Carbon Dioxide is manufactured and delivered under applicable standards per each country's regulatory requirements. In the United States, the Food and Drug Administration has cleared the use of Medical Carbon Dioxide for the route of inhalation for humans but not yet for transdermal delivery with D'OXYVA. Transportation of Medical Carbon Dioxide via any postal or courier service requires certification for handling Dangerous Goods (HAZMAT) by the U.S. Department of Transportation (DOT). Use of unapproved substances and products may be illegal, cause serious injury and even death!


Circularity Healthcare's platform biotech solution, D'OXYVA is utilizing the well-known Medical Carbon Dioxide cleared by the Food and Drug Administration in the United Stated (USP UN1013) and by other regulatory agencies worldwide for use in the inhalation route like anesthesia as a non-toxic pharmaceutical substance. D'OXYVA enjoys an investigational device exemption (IDE) status and according to a recent review by the U.S. FDA in February of 2016, it requires no clearance of any kind for being marketed as a non-invasive transdermal delivery system of carbon dioxide to improve microcirculation.


Medical Gases intended for use in the United States are considered drugs by the U.S. FDA. Medical gases (e.g., oxygen, carbon dioxide, helium, nitrogen, nitrous oxide, medical air, and 49 combinations of these) are drugs within the meaning of section 201(g)(1) of the Federal Food, Drug, and Cosmetic Act (Act) and pursuant to section 503(b)(1)(A) of 51 the Act are required to be dispensed by prescription. Compressed Medical Gases (CMG) are any liquefied or vaporized gas alone or in combination with other gases which is a drug as defined by Section 201(g)(1) of the Act. As such, establishments that manufacture or process Medical Gases are considered drug manufacturers. Therefore, Medical Gas Establishments are subject to U.S. FDA drug registration and listing requirements
