Evolving Bioequivalence Approaches for Complex Generics and Long-Acting Injectables

Monday, November 2, 2026

3:45 p.m. - 4:45 p.m.

This session will examine evolving scientific and regulatory approaches to establishing bioequivalence for complex generic drug products, with a focus on long-acting injectables and other complex dosage forms. Panelists will discuss how in vitro, model-informed, analytical, and performance-based approaches may reduce reliance on large, lengthy clinical endpoint or pharmacokinetic studies while maintaining robust standards for quality, safety, efficacy, and therapeutic equivalence. The session will also highlight recent and revised FDA product-specific guidances that have enabled more flexible, science-based pathways across complex APIs, peptides and oligonucleotides, orally inhaled and nasal products, topical and locally acting products, and complex drug-device combination products.
