Oligonucleotide APIs and DPs: Assuring A Strong Quality Roadmap For Development

Oligonucleotide APIs and DPs: Assuring A Strong Quality Roadmap For Development

As oligonucleotide therapeutics development accelerates due to advances in chemistry and delivery technologies, understanding how to ensure quality of oligonucleotide Active Pharmaceutical Ingredients (APIs) and Drug Products (DPs) becomes crucial. This includes anticipating regulatory expectations, beginning with good science and understanding the drug development process. Responsibilities of Sponsor and Vendors Many start-up or mid-size life…

Chemoenzymatic Synthesis of siRNA and sgRNA Using Ligation Technology

Chemoenzymatic Synthesis of siRNA and sgRNA Using Ligation Technology

Introduction Advancements in RNA therapeutics are increasing the demand for high-quality synthetic oligonucleotides including siRNA (small interfering RNA) and sgRNA (single guide RNA). While conventional solid-phase oligonucleotide synthesis (SPOS) remains the primary method for siRNA and sgRNA production, its limitations in scalability, sustainability, quality, and cost hinder its ability to meet the anticipated market demands….
