ABSTRACT
Background
MYL-1401O; trastuzumab-dkst (Ogivri™; Mylan Inc.) is a biosimilar to the trastuzumab reference product (Herceptin®; Genentech, USA). Assessment of physicochemical stability and biological activity for the non-reconstituted, reconstituted, and infused solution over an extended, clinically relevant duration is critical for ensuring optimal patient outcomes and health resource utilization.
Methods
The physicochemical and biological stability of MYL-1401O was assessed in non-reconstituted vials stored at 25 °C ± 2 °C/60% ± 5% relative humidity (RH) for 6 months, reconstituted 21 mg/mL solution in vials stored at 2 °C to 8 °C for 10 days, and diluted in 0.9% saline-containing infusion bags at 0.3 mg/mL and 4.0 mg/mL stored for 77 days at 2 °C to 8 °C, plus an additional 2 days at 25 °C ± 2 °C/60% ± 5% RH.
Results
At all storage conditions tested, MYL-1401O was physicochemically and biologically stable for extended duration and under various temperature and humidity conditions.
Conclusions
MYL-1401O retained its physicochemical and biological stability under different storage conditions, which supports advanced preparation of MYL-1401O, better efficiency, less wastage, and cost-savings for better patient management.
