MODIFIED POLYNUCLEOTIDES FOR THE PRODUCTION OF ONCOLOGY-RELATED PROTEINS AND PEPTIDES
The invention relates to compositions including polynucleotides encoding polypeptides which have been chemically modified by replacing the uridines with 1-methyl-pseudouridine to improve one or more of the stability and/or clearance in tissues, receptor uptake and/or kinetics, cellular access by the compositions, engagement with translational machinery, mRNA half-life, translation efficiency, immune evasion, protein production capacity, secretion efficiency, accessibility to circulation, protein half-life and/or modulation of a cell's status, function, and/or activity.
1 . A pharmaceutical composition comprising:
a plurality of lipid nanoparticles comprising a cationic lipid, a non-cationic lipid, a cholesterol, and a PEG lipid, wherein the plurality of lipid nanoparticles has a mean particle size of between 80 nm and 150 nm; and
wherein the lipid nanoparticles comprise an mRNA encoding an oncology-related polypeptide,
wherein the mRNA comprises:
(i) a 5′-cap structure;
(ii) a 5′-UTR;
(iii) an open reading frame encoding the oncology-related polypeptide and consisting of nucleotides including uracil, cytosine, adenine, and guanine;
(iv) a 3′-UTR; and
(v) a poly-A region of least 100 nucleotides in length.
2 . The pharmaceutical composition of claim 1 , wherein the cationic lipid is a biodegradable cationic lipid.
