Overview

Faster, clearer protein therapeutic answers

Global regulators increasingly expect detailed analytical and biological evidence to demonstrate comparability between biosimilars and reference products. This requires developers to thoroughly assess multiple protein batches, emphasizing precise biosimilar protein characterization and deeper characterization of biotherapeutic proteins.

Waters’ integrated solutions provide a comprehensive platform for streamlined, reliable analysis of biosimilar and reference product attributes, including:

  • Primary structure (sequence)
  • Higher‑order structure, including aggregation
  • Post‑translational modifications
  • Intentional chemical modifications such as PEGylation

Establish biosimilar comparability with confidence—partner with Waters for safer, more effective medicines.

Regulatory Insight: FDA Draft Guidance (2025)

Recent FDA draft guidance enables developers to bypass comparative clinical efficacy studies if advanced analytical data provides sufficient evidence of biosimilarity—potentially eliminating one of the costliest development steps and accelerating timelines dramatically.

This shifts an even greater responsibility onto biologics and biosimilars protein analysis and robust analytical testing.

Applications

Owing to the inherent complexity of biotherapeutics, developers must demonstrate comprehensive molecular characterization, robust and well‑controlled manufacturing processes, and ongoing monitoring of product and critical quality attributes. Within biosimilar development, intact mass and subunit analyses are core analytical tools, used to confirm molecular mass, detect sequence errors and post‑translational modifications, and identify major molecular variants that warrant further investigation.

Application Notes

Comprehensive tools for intact protein analysis

Peptide mapping is essential for establishing similarity through high sequence coverage and the detection of clinically relevant modifications at the peptide level. Non‑reducing digests further support characterization of biosimilars by enabling disulfide linkage confirmation and equivalence verification to innovator molecules.

Waters solutions deliver high‑precision data to support faster decision‑making across development and manufacturing.
