Overcoming Bottlenecks in Quantifying Oligonucleotide Therapeutics Using LC-MS/MS Technology and Expertise to Reduce Risk and Increase Your Speed to Market Overcoming Bottlenecks in Quantifying Oligonucleotide Therapeutics 1 Introduction Oligonucleotides are a rapidly growing family of biopharmaceutical products whose therapeutic potential is now primed and waiting to be unlocked. First recognized for their ability to modulate gene expression more than three decades ago, advances in fundamental research and enabling technologies have doubled the number of oligonucleotide drugs on the market since the start of 2016, with many more expected in the years to come. This important class of therapeutics is coming of age, and for biopharmaceutical companies, the race is on to launch the next generation of innovative oligonucleotide products. Bringing safe and effective oligonucleotides to market relies on robust bioanalysis workflows. However, given their unique physicochemical properties, oligonucleotides require advanced and unique analytical strategies that go above and beyond those used to study conventional small molecule or even peptide and protein drugs. Implementing ineffective solutions that poorly meet these needs can cause substantial bioanalysis backlogs, lengthy study delays or even suboptimal development decisions based on incomplete or incorrect data. Even the largest and most experienced drug developers are not immune to these challenges. To accelerate the development of your oligonucleotide therapeutics and drive clinical success, you need robust bioanalysis solutions underpinned by industry- leading analytical expertise, cutting-edge technologies and proven workflows built on decades of experience. Abstract Developing bioanalytical solutions to support oligonucleotide drug programs can be challenging due to the unique physicochemical properties of these molecules. This whitepaper outlines both the established and the unique liquid chromatography and extraction technologies Covance has developed to ensure you remain at the forefront of oligonucleotide innovation. Learn how you can benefit from the workflows to: ▶ Eliminate bottlenecks and accelerate timelines with state-of-the-art liquid chromatography, focused detection and extraction technologies that generate accurate and robust data ▶ Rapidly receive the results you need through world-class scientific expertise based on decades of experience in solving complex bioanalytical challenges ▶ Capitalize on the rapidly expanding oligonucleotide marketing with the support of technologies and expertise Now Is the Time to Get Ahead of the Oligonucleotide Therapeutics Field Oligonucleotide therapeutics However, following extensive encompass a wide range of research efforts and a large number different modalities, with antisense of clinical trials, the last few years oligonucleotides (ASOs), small have seen an upsurge in the number interfering RNA (siRNA), micro of oligonucleotide drugs that RNA (miRNA) antagomirs/mimetics have been granted FDA approval, and oligonucleotide aptamers among signaling the start of a new era in the most widely utilized families.1 oligonucleotide therapeutics.
