Marinomed Biotech AG: First Carragelose products receive new Medical Device Regulation (MDR) certification

• Two Carragelose nasal sprays have received declaration of conformity under the new medical device regulation - certificates for further products expected later in the year
• Extensive clinical data for Carragelose facilitates challenging demands for MDR transition
• MDR-compliance is a major asset for medical devices and adds significant value to Carragelose portfolio
• Evaluation process regarding strategic options for the Carragelose business ongoing; due diligence phase continuing but no agreements made to date

Korneuburg, Austria, 11. September 2024 – Marinomed Biotech AG (VSE:MARI) has received the certificates for the first two Carragelose products under the new medical device regulation (MDR). The European Union (EU) implemented the new medical device regulation in May 2021, replacing the previously valid medical device directive (MDD) and increasing scrutiny on medical device safety throughout the full product lifecycle. The MDR sets new EU-wide standards regarding the requirements for safety, performance, quality of clinical data and overall technical documentation for medical devices. Compliance with the new MDR is the prerequisite for the marketing of medical devices in the EU after the end of the transition period in 2028.

The declaration of conformity for the first Carragelose products represents a major milestone for the whole portfolio and creates a promising foundation for the certification of the other Carragelose products. Furthermore, successful MDR transition adds significant value to the Carragelose asset. As announced mid-December 2023, the Company commenced an evaluation process regarding strategic options for the Carragelose business area. Without any relevant interim step having occurred, the Company updates the market that potential buyers are still in the process of conducting due diligence. To date, no binding agreements have been concluded. In this process, Marinomed aims for a decision to be made and announced by the end of the year.

Eva Prieschl-Grassauer, CSO of Marinomed, comments: “MDR-transition and the associated necessary documentation is very demanding. However, thanks to the excellent work of our regulatory affairs team and the extensive clinical data that we have generated for Carragelose over the years, we are able to meet the new requirements. The issuing of these certificates is further confirmation of the quality, safety and appropriate technical documentation of our Carragelose products and increases the value of this asset, also for a potential strategic partner. We are proud to have received the first certificates well before the end of the transition period in 2028. We are confident that the other products will also be certified under the new MDR and will therefore continue to be approved for marketing and distribution in the EU.”
