Abstract: The present disclosure provides alternative nucleosides, nucleotides, and nucleic acids, and methods of using them. In some aspects, the disclosure provides mRNA wherein the uracil content has been modified and which may be particularly effective for use in therapeutic compositions, because they may benefit from both high expression levels and limited induction of the innate immune response. In some aspects, the disclosure provides methods for the production of pharmaceutical compositions including mRNA without reverse phase chromatography.

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 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 invention relates to compositions and methods for the preparation, manufacture and therapeutic use of signal-sensor polynucleotides, primary transcripts and mmRNA molecules.

Abstract: The disclosure features immune cell delivery lipid nanoparticle (LNP) compositions that allow for enhanced delivery of agents, e.g., nucleic acids, such as therapeutic and/or prophylactic RNAs, to immune cells, in particular T cells, as well as B cells, dendritic cells and monocytes. The LNPs comprise an effective amount of an immune cell delivery potentiating lipid such that delivery of an agent by an immune cell delivery LNP is enhanced as compared to an LNP lacking the immune cell delivery potentiating agent. Methods of using the immune cell delivery LNPs for delivery of agents, e.g., nucleic acid delivery, for protein expression, for modulating immune cell activity and modulating immune responses are also disclosed.
