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.
