To explore the feasibility of multivariate data analysis (MVDA) in formulation robustness study of biopharmaceutical drug products by taking an antibody-drug conjugate (ADC) HS630 as example.
A two-level fractional factorial design with five factors was used to investigate the effects of protein content, contents of three excipients and pH on critical quality attributes. After preparation, the samples of each group were exposed to high temperature for 28 d and light for 10 d, respectively. The contents of polymers and free DM1 were detected and analyzed.
Partial least squares (PLS) method was used for model fitting and data analysis, and the model seemed good with an acceptable predictive capability. All the excipients and pH had no significant effect on the contents of polymers and free DM1. Although it was not significant, a higher free DM1 content was noticed with higher protein content and higher pH conditions. Light and high temperature had significant effects on the attributes of drug product with a similar trend but small ranges. The formulation in the studied range was regarded as robust.
Taking MVDA method into formulation robustness study of drug products can analyze the multi-dimensional data obtained under different treatment conditions. The critical components of the formulation can be identified, and the influence of treatment conditions on the critical quality attributes can be investigated.
