Potency Assay Variability Estimation in Practice. [PDF]
Abstract During the drug development process, testing potency plays an important role in the quality assessment required for the manufacturing and marketing of biologics. Due to multiple operational and biological factors, higher variability is usually observed in bioassays compared with physicochemical methods.

Quality by Design Based Chromatography Technique Development and Validation for the Medicine Venetoclax (for Chronic Leukemia), in the Context of Impurities Including Degradation Products. [PDF]
ABSTRACT The present research study describes the Venetoclax (VEN)‐related substances test method using RP‐HPLC/DAD techniques. It was developed and validated according to ICH Q14 and Q2(R2) guidelines. The substances were separated using an X‐Bridge Phenyl column (150 mm × 4.6 mm, 3.5 μm) and a gradient program.
