Isolated methylmalonic acidemia/aciduria (MMA) due to MMUT enzyme deficiency is an ultra-rare pediatric disease with high morbidity and mortality, with no approved disease-altering therapies. Previous publications showed that systemic treatment with a codon-optimized mRNA encoding wild-type human MMUT (MMUT) is a promising strategy for treatment of MMA. We developed a second-generation drug product, mRNA-3705, comprised of an mRNA encoding the MMUT enzyme formulated in a lipid nanoparticle (LNP) with incorporation of enhancements over the previous clinical candidate mRNA-3704.

Despite its exceptionally low circulating concentration, apolipoprotein (apo) A-V is a potent modulator of plasma triacylglycerol levels. The secretion efficiency of nascent apoA-V was investigated in cultured cells transfected with mRNA. Following transfection of HepG2 cells with wild type apoA-V mRNA, apoA-V protein was detectable in cell lysates by 6 h.
