Biologic Therapeutics Development, Part 2: Regulatory Pathways and Pharmacometric Analysis

Camargo

Like with small molecules, clinical trials of biologics are designed to determine pharmacokinetics (PK), pharmacodynamics (PD), safety, and efficacy. PK studies are conducted to confirm that dosimetry remains unchanged, and toxicology studies are needed to confirm that the therapeutic ratio and safety profile remain unchanged.

Unlike small-molecule generic drugs, biosimilars do not need to demonstrate bioequivalence to the innovator product. If the FDA licenses an interchangeable, that means that switching between the interchangeable and the reference doesn’t increase the safety risk or decrease the effectiveness compared to using the reference only,” says Brahme.
