High Concentrations Made Easy: BioSpring's Next Level UF/DF Method for Improved Oligonucleotide API Manufacturing
Ultrafiltration is widely used in oligonucleotide manufacturing, particularly for the desalting and concentration of active pharmaceutical ingredients (APIs). With traditional ultrafiltration, the concentration that can be achieved is limited. This creates a significant bottleneck in the production of powdered APIs, where ultrafiltration is frequently used as a pre-lyophilization step and determines the maximum batch size that can be obtained with the freeze dryer capacity. Moreover, traditional ultrafiltration often cannot support the manufacturing of oligonucleotide solution APIs because it fails to exceed the concentration of subcutaneous drug products. To address these issues, BioSpring has developed an in-house ultrafiltration/diafiltration (UF/DF) technique, optimizing nucleic acid concentration and enhancing production efficiency.
Regulatory Feedback On Late-Stage Programs - A CDMO Perspective
Advancing an oligonucleotide therapeutic into late-stage development presents unique challenges, requiring a well-defined regulatory and validation strategy. This talk provides key insights from a CDMO perspective on molecule classification, process validation steps, regulatory expectations, and the role of release specifications. Additionally, it highlights best practices for analytical method validation tailored to Phase III and commercial programs, ensuring regulatory compliance and product success.
Enabling Therapeutic Progress with Oligonucleotide Bioanalysis
Whether you are seeking regulatory approval, evaluating drug metabolism, or planning your next clinical phase, it is crucial to have reliable data when analyzing oligonucleotidebased drugs and their metabolites in biofluids and tissues. Oligonucleotides like ASOs, siRNAs, and guide RNAs bring unique challenges: diverse chemical modifications and conjugations, complex degradation pathways, and interfering sample background make standard bioanalytical methods unreliable or insufficient. Accurate bioanalysis requires tailored analytical strategies that account for this complexity.
