As a result of our meetings with the FDA in 2009, we decided to discontinue all of our products that were subject to the Prescription Drug Wrap-Up program, with the exception of epinephrine in vial form. These products were all produced at our subsidiary, IMS. During the third quarter of 2010, the FDA requested that we reintroduce several of the withdrawn products to help address a national drug shortage, while we prepared and filed applications for approval of the products. Between August and October 2010, we reintroduced our epinephrine prefilled syringes.
In February 2017, the FDA requested that we discontinue the manufacturing and distribution of our epinephrine injection, USP vial product, which had been marketed under the “grandfather” exception to the “FDA’s Prescription Drug Wrap-Up program”. We discontinued selling this product in the second quarter of 2017. In April 2020, the FDA granted approval of our epinephrine injection, USP 30mg/mL multiple dose vial, and we launched the product in May 2020.
The FDA granted approval of our products that were previously marketed under the “grandfather” exception, such as atropine sulfate injection 0.1mg/mL in the 10mL Luer-Jet® prefilled syringe in October 2020, dextrose injection 50% in the 50mL Luer-Jet® prefilled syringe in March 2021 and our morphine sulfate injection USP, 1mg/mL 30mL in April 2021.
Our only unapproved product currently on the market is the epinephrine prefilled syringe. For the years ended December 31, 2021, 2020, and 2019, we recorded net revenues of $27.8 million, $13.2 million, and $13.9 million, respectively, for epinephrine prefilled syringes and for the six months ended June 30, 2022 and 2021, we recorded net revenues of $14.7 million and $12.3 million, respectively, for this product. We submitted an NDA for our epinephrine prefilled syringe in order to mitigate all risk associated with the marketing of unapproved drug products. Prior to the approval of our NDA submission, we continue to operate in compliance with the FDA Compliance Policy Guide, CPG Sec. 440.100 Marketed New Drugs Without Approved NDAs and ANDAs. In 2020, the HHS announced that termination of the FDA Unapproved Drugs Initiative (UDI), citing that the Compliance Policy Guide (CPG) issued with the UDI was “linked to prescription drug price increases and shortages” and announced its withdrawal. However, under the Biden administration, in May 2021, HHS and FDA, each under new leadership, jointly issued a withdrawal-of-the-termination notice, withdrawing the prior HHS notice of termination issued under the Trump administration, citing multiple legal and factual inaccuracies. New guidance from the agency is anticipated in the future. The long-term impact of this policy and other measures promulgated by the Biden administration on our business remains unclear.
Our business and operations have been impacted in the past, and may be impacted in the future, in the event of system breach or failure.
We, our collaborators, third-party providers, distributors, customers and other contractors utilize information technology systems and networks to transmit, store and otherwise process electronic data in connection with our business activities, including our supply chain processes, operations and communications. This includes our clinical data and business proprietary information, Electronic Data Interchange, or EDI, on purchase orders, invoices, chargebacks, etc. We, and others on our behalf, also collect, transmit, store and otherwise process certain data relating to individuals, including about our personnel, business partners, and others, which may be subject to applicable data protection, security and privacy laws and regulations that require adoption of minimum information security standards. The cost of compliance with applicable data protection, security and privacy laws and regulations have increased and may increase in the future.
Despite our implementation of security measures to protect the confidentiality, integrity, and availability of the systems, networks and data within our control from various threats (e.g., cyber-attacks, system breaches, malware, viruses, hacking, fraudulent use, social engineering attacks, phishing attacks, ransomware attacks, credential-stuffing attacks, denial-of-service attacks, unauthorized access, insider threats, accidental disclosures, intellectual property theft and economic espionage, exploitable vulnerabilities, defects or bugs in our or our third-party providers’ systems, natural disasters, war, terrorism, telecommunications and electrical outages, breakdowns, damage, interruptions), we have experienced and may continue to experience cyber-attacks of varying degrees from time to time. For example, in the first quarter of 2022, our Chinese subsidiary, ANP, was subject to a security incident that resulted in a temporary disruptions to some of their internal computer systems. We are currently working with ANP to improve and add additional security measures to their systems and networks. We have incurred costs to respond to the ANP incident. In addition, in the
