XATP for Pharmaceutical Supply Chain Security

In 2013, the Drug Supply Chain Security Act was signed into law to address the growing threat of counterfeit drugs and to ensure prescription drugs remain safe and effective for patients. As part of this law, US pharmaceutical supply chain stakeholders are required to confirm the authorized status of trading partners for transactions and information disclosures, even when there is no prior business relationship. While larger Authorized Trading Partners (ATPs) have connectivity solutions in place, newer and smaller ATPs have not traditionally participated, including tens of thousands of dispensers. This complicates the path of the US pharmaceutical supply chain path to unlock the full potential of the interoperable system mandated by DSCSA. XATP is a blockchain-backed framework for ATP authentication and enhanced verification in a real-world pharmacy with genuine drug packages. Using just a mobile phone, dispensers can submit supporting documentation to authenticate their identities, and scan 2D drug barcodes to submit drug verification requests to manufacturers. Manufacturers authenticate the identity of requesting dispensers with verifiable credentials and respond to verification requests. These responses can be used to create Product Verification Certificates to support saleable returns.
