Consultant POV

“Oligonucleotide synthesis is the manufacturing backbone of the nucleic acid therapeutics revolution. Every ASO drug from Ionis, every siRNA from Alnylam, every CRISPR therapy requires large-scale GMP oligo synthesis. The industry spent 20 years validating the biology; now the constraint is manufacturing scale. The CDMOs that build 1,000–10,000 kg GMP oligo synthesis capacity in the next five years will capture the commercial manufacturing contracts for the next generation of nucleic acid drugs.”
