Sequence variant analysis is essential for characterizing biotherapeutic proteins, but high rates of false positives can slow development. Subtle yet potentially profound changes to a protein's amino acid sequence can dramatically alter its function and impact patient safety. This paper reveals how low-level posttranslational modifications introduced during protein digestion can be misidentified as sequence variants. By implementing time-course digestion during method development, it can effectively distinguish true variants from artifacts, significantly reducing data analysis time. Case studies also show how to integrate time-course digestion into a workflow.
In October, FDA reorganized rare disease development around a fit-for-purpose framework and a new pathway for individualized gene editing. Regulators in Europe and the UK set out long-term plans for clinical trials, AI, and moving away from animal testing.
Clinical, manufacturing, safety, and commercial teams all lean on shared data. They need to agree on who publishes each data product, who can use it, and what evidence goes with it.
The FDA approves VOCERYQ, the first DNA medicine, for RRP surgery reduction, raising plasmid, drug-device, and confirmatory trial manufacturing demands.
The PharmTech team focused on its coverage of AAPS PharmSci 360 this week, conducting interviews with experts on a range of topics including formulation platforms, AI, amorphous solid dispersions, and animal studies.
