Repligen Launches Novel AVIPure® dsRNA Resin in OPUS® Pre-packed Columns

Breakthrough Innovation for the Purification of mRNA Therapeutics and Vaccines

WALTHAM, Mass., Dec. 09, 2024 (GLOBE NEWSWIRE) -- Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today announced the launch of AVIPure^® dsRNA Clear OPUS^® columns, a groundbreaking solution designed to simplify and enhance the production of mRNA therapeutics and vaccines. This novel affinity chromatography offering marries Repligen’s breakthrough dsRNA purification resin with its flagship OPUS pre-packed columns. The AVIPure dsRNA Clear resin offers unmatched performance in the removal of double-stranded RNA (dsRNA) impurities from transcribed RNA. As the market for mRNA-based biologics has expanded, so has the critical need for better dsRNA removal, to enable the highest levels of drug efficacy in patients, while reducing or preventing any undesirable immune responses. The AVIPure dsRNA Clear OPUS columns directly address this need, with a convenient, closed system for mRNA manufacturers.

The AVIPure dsRNA Clear resin launch follows last week’s formal completion by Repligen of its acquisition of Tantti Laboratory Inc., announced on July 29, 2024.

Olivier Loeillot, President and Chief Executive Officer for Repligen said, “We are thrilled to be introducing this innovative technology to market. The AVIPure dsRNA Clear resin offering represents the initial of several planned Repligen-owned resin launches in 2025, that combine Tantti’s innovative DuloCore^® bead technology with our AVIPure affinity ligands. Add on OPUS, and we believe this is just our first step toward building a portfolio of gold standard products for new modality purification.”

The AVIPure dsRNA Clear resin product combines our proprietary affinity ligands with Tantti’s DuloCore^® base bead technology. The result is a 2-3 log reduction of dsRNA impurities in just one minute of residence time in flow through mode. Unlike traditional methods, this advanced solution eliminates the need for heat or solvents, providing an easy-to-use, scalable option for manufacturers, and enabling a highly efficient, cost-effective process that ensures the production of high-purity mRNA therapeutics and vaccines. Designed for flexibility and performance, the resins come pre-packed in OPUS chromatography columns, ensuring seamless integration into biomanufacturing workflows.

Umay Saplakoglu, Vice President of Product Management at Repligen said, “Our AVIPure dsRNA Clear OPUS columns will address one of the critical challenges in the production of mRNA therapeutics by providing a technology that combines speed, scalability and exceptional impurity removal while simplifying the workflow. This launch reaffirms our commitment to enabling our customers to deliver safe, high-quality biotherapeutics while reducing costs.”
