Manufacturing and Analytical Processes for 2-O-(2-Methoxyethyl)-Modified Oligonucleotides

WithDaniel C. Capaldi, Anthony N. Scozzari

The approval of Vitravene in 1998 for the treatment of CMV retinitis in AIDS sufferers stands as an early testament to the promise of antisense technology. More recently, a second oligonucleotide-based therapeutic, Macugen,* was approved for the treatment of wet, age-related macular degeneration (AMD). These successes and encouraging clinical trial results obtained using other oligonucleotides† suggest that substantial quantities of high-quality modified DNA and RNA will be required in the near future.
