The present invention provides, among other things, methods of quantitating mRNA capping efficiency, particularly mRNA synthesized in vitro. In some embodiments, methods according to the present invention comprise providing an mRNA sample containing capped and uncapped mRNA, providing a cap specific binding substance under conditions that permit the formation of a complex between the cap specific binding substance and the capped mRNA, and quantitatively determining the amount of the complex as compared to a control, thereby quantifying mRNA capping efficiency.

Quantitative assessment for cap efficiency of messenger RNA

The present invention relates, in part, to methods for large-scale purification of mRNA. The method includes, at least, a step of centrifuging an mRNA suspension in a centrifuge comprising a porous substrate at a speed sufficient to remove process contaminants and to precipitate purified mRNA composition onto the porous substrate.

Methods for purification of messenger RNA

Disclosed are cationic polymers comprising monomers such as those described in Formula (I), Such polymers can be useful for the preparation of therapeutic compositions (e.g., compositions comprising nucleic acids such as mRNA). Additionally, therapeutic compositions comprising these cationic, biodegradable polymers can have improved properties and reduced toxicity.

Cationic polymers

The present invention provides, among other things, methods and compositions for treating primary ciliary dyskinesia (PCD) based on mRNA therapy. The compositions used in treatment of PCD comprise an mRNA comprising a dynein axonemal heavy chain 5 (DNAH5) coding sequence and are administered at an effective dose and an administration interval such that at least one symptom or feature of PCD is reduced in intensity, severity, or frequency or has a delayed onset. mRNAs with optimized DNAH5 coding sequences are provided that can be administered without the need for modifying the nucleotides of the mRNA to achieve sustained in vivo function.

The present invention provides, among other things, methods of purifying messenger RNA (mRNA) including the steps of subjecting an impure preparation comprising in vitro synthesized rnRNA to a denaturing condition, and purifying the rnRNA from the impure preparation from step (a) by tangential flow filtration, wherein the mRNA purified from step (b) is substantially free of prematurely aborted RNA sequences and/or enzyme reagents used in in vitro synthesis.

The present invention provides, among other things, methods of treating ornithine transcarbamylase (OTC) deficiency, including administering to a subject in need of treatment a composition comprising an mRNA encoding an ornithine transcarbamylase (OTC) protein at an effective dose and an administration interval such that at least one symptom or feature of the OTC deficiency is reduced in intensity, severity, or frequency or has delayed onset. In some embodiments, the mRNA is encapsulated in a liposome comprising one or more cationic lipids, one or more non-cationic lipids, one or more cholesterol-based lipids and one or more PEG-modified lipids.

Messenger RNA therapy for the treatment of ornithine transcarbamylase deficiency

The present invention provides, among other things, an improved method of treating cystic fibrosis (CF) in a human subject. The method comprises administering a composition comprising an mRNA encoding a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein at a concentration of 0.5 mg/mL or greater to a human subject via nebulization. The composition is aerosolized using a nebulizer and a nominal dose of the mRNA is administered to the human subject via the nebulizer over a period of time, typically at least 30 minutes, at a suitable nebulization rate, e.g., at least 0.2 mL/minute.
