'Totality of Evidence' Approach in the Development of GP2017, an Approved Adalimumab Biosimilar

© 2024. The Author(s)..

INTRODUCTION: Hyrimoz®, (GP2017 [SDZ-ADL]), is a biosimilar to Humira® (REF-ADL). SDZ-ADL was approved in 2018 by both the United States Food and Drug Administration (US FDA) and European Medicines Agency (EMA) for the indications of REF-ADL not protected by orphan exclusivity. In 2023, the US FDA and EMA also approved a citrate-free high-concentration formulation (HCF) of SDZ-ADL.

TOTALITY OF EVIDENCE-THE APPROACH: Approval of SDZ-ADL was based on data gathered using the US FDA, EMA and World Health Organization (WHO)-recommended step-wise Totality of Evidence approach. This approach is a robust dataset confirming high confidence in analytical, functional, pharmacokinetic (PK) and clinical biosimilarity between the biosimilar and reference medicine determined through analytical and clinical investigation.

EVIDENCE OF BIOSIMILARITY: Evidence supporting the biosimilarity of SDZ-ADL and REF-ADL was reported at each stage of investigation. Comprehensive comparative analytical and functional assessments demonstrated that SDZ-ADL was analytically indistinguishable from REF-ADL in required critical quality attributes, including receptor binding. Phase I clinical data showed PK similarity of SDZ-ADL and REF-ADL in healthy volunteers, with similar safety, tolerability and immunogenicity profiles. Phase III confirmatory efficacy and safety studies, ADACCESS (included in US/EU dossiers) and ADMYRA (separate to US/EU dossiers), both confirmed that SDZ-ADL's efficacy, safety, and immunogenicity matched REF-ADL in all patient groups with no clinically meaningful differences. More recently, this data package was the basis for a citrate-free HCF of SDZ-ADL to be developed, and its PK, safety and immunogenicity were confirmed against the initially approved formulation of SDZ-ADL.

CONCLUSION: Overall, the Totality of Evidence provided for biosimilar adalimumab, SDZ-ADL, confirmed the analytical, functional and clinical similarity of SDZ-ADL to REF-ADL, supporting its regulatory approval and providing a data bridge with which to evaluate and support the approval of citrate-free HCF SDZ-ADL for clinical use.
