Polyplus’ LipidBrick is designed to expand the scope of lipid nanoparticle formulation usage in mRNA therapeutics and vaccine development.

Polyplus, a French provider of solutions for advanced biologic and cell and gene therapy production, announced a novel cationic lipid nanoparticle (LNP) formulation for messenger RNA (mRNA) therapeutic and vaccine development on March 14, 2023. Set for release in April 2023, the LipidBrick IM21.7c is a formulation designed to expand the scope of LNP usage in various therapeutic and oncology applications, as well as prophylactic vaccines.

The formulation is designed to overcome current-generation ionizable lipid challenges used in current LNPs by enabling a wider in-vivo biodistribution and decreasing accumulation in the liver. According to a company press release, proof of concept work demonstrated that it successfully modulates the overall charge of LNPs, improving drug efficiency and formulation stability with no additional safety concerns.

“Polyplus draws on over 20 years legacy in cationic polymer and lipid-based delivery systems for both in-vitro and in-vivo models to power mRNA therapeutics,” said Mario Philips, CEO, Polyplus, in the release. “As we carry forward this legacy, we are working to ensure that our offer opens new possibilities to improve LNP formulation to meet the growing demand of the mRNA therapeutic market. LipidBrick IM21.7c is already used in jetMESSENGER and liposomal formulations for mRNA delivery, as a ready-to-use solution that requires no onsite formulation.”
