Abstract: The present disclosure relates to the use of nucleic acid (e.g., mRNA) combination therapies for the treatment of cancer. The disclosure provides compositions, and methods for their preparation, manufacture, and therapeutic use, wherein those compositions comprise at least two polynucleotides (e.g., mRNAs) in combination wherein the at least two polynucleotides are selected from the group consisting of (i) a polynucleotide encoding an immune response primer (e.g., IL23), (ii) a polynucleotide encoding an immune response co-stimulatory signal (e.g., OX40L), (iii) a polynucleotide encoding a checkpoint inhibitor (e.g., an anti CTLA-4 antibody), and, (iv) a combination thereof. The therapeutic methods disclosed herein comprise, e.g., the administration of a combination therapy disclosed herein for the treatment of cancer, e.g., by reducing the size of a tumor or inhibiting the growth of a tumor, in a subject in need thereof.

Abstract: The invention relates to mRNA therapy for the treatment of cystic fibrosis. mRNAs for use in the invention, when administered in vivo, encode cystic fibrosis transmembrane conductance regulator (CFTR), isoforms thereof, functional fragments thereof, and fusion proteins comprising CFTR. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery to cells and/or tissues in subjects, when administered thereto. mRNA therapies of the invention increase and/or restore deficient levels of CFTR expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of toxic metabolites associated with deficient CFTR activity in subjects.

Abstract: The invention relates to mRNA therapy for the treatment of Fabry disease. mRNAs for use in the invention, when administered in vivo, encode human the ?-galactosidase A (GLA), isoforms thereof, functional fragments thereof, and fusion proteins comprising GLA. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery to cells and/or tissues in subjects, when administered thereto. mRNA therapies of the invention increase and/or restore deficient levels of GLA expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of toxic metabolites associated with deficient GLA activity in subjects, namely Gb3 and lyso-Gb3.

Abstract: The disclosure relates to polynucleotides comprising an open reading frame of linked nucleosides encoding human methylmalonyl-CoA mutase precursor, human methylmalonyl-CoA mutase (MCM) mature form, or functional fragments thereof.
