Merck and Orna Therapeutics Collaborate to Advance Orna’s Next Generation of RNA Technology

Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Orna Therapeutics, a biotechnology company pioneering a new investigational class of engineered circular RNA (oRNA) therapies, today announced a collaboration agreement to discover, develop, and commercialize multiple programs, including vaccines and therapeutics in the areas of infectious disease and oncology.

Under the terms of the agreement, Merck will make an upfront payment to Orna of $150 million, which will be expensed by Merck in the third quarter of 2022 and included in non-GAAP results. In addition, Orna will be eligible to receive up to $3.5 billion in development, regulatory, and sales milestones associated with the progress of the multiple vaccine and therapeutic programs, as well as royalties on any approved products derived from the collaboration. Orna will retain rights to its oRNA-LNP technology platform and will continue to advance other wholly owned programs in areas such as oncology and genetic disease. Merck will also invest $100 million of equity in Orna’s recently completed Series B financing round.

Orna’s proprietary oRNA technology creates circular RNAs (oRNAs) from linear RNAs by self-circularization. oRNA molecules have been shown to have greater stability in vivo than linear mRNA and have the potential to produce larger quantities of therapeutic proteins inside the body. Newly synthesized oRNA molecules are more compactly packaged into custom lipid nanoparticles (LNPs), which Orna has engineered to target key tissues in the body. Preclinical data, including presentations at the 2022 American Society of Gene & Cell Therapy (ASGCT) Annual Meeting, have demonstrated the potential of oRNA expression and delivery as an approach for further development in multiple areas, including vaccines and oncology therapeutics.

“This broad strategic collaboration brings together Merck’s significant expertise in nucleic acid biology, clinical development, and manufacturing with Orna’s compelling circular RNA technology to explore the opportunity to develop a new generation of potential vaccines and therapeutics,” said Fiona Marshall, senior vice president and head of discovery, preclinical and translational medicine at Merck Research Laboratories. “We look forward to working with the talented scientific and technical teams at Orna."
