The October 2025 FDA draft guidance for biosimilars marks a major shift toward greater reliance on analytical data. Most notably, it signals a move to reduce or even eliminate comparative efficacy studies when robust analytics can provide equivalent insight, detecting subtle differences that clinical studies often miss. Biosimilar development will continue to require comprehensive analytical packages, with emphasis on orthogonal techniques. This session features Colette Quinn from Waters Corporation, who discusses how analytics support biosimilar development and help meet the FDA’s “totality-of-evidence” expectations.
This week, Chromatography Online explored how the technique is advancing wastewater drug monitoring, siRNA method development, and food safety testing, with previews of RAFA 2026 and a return to HPLC fundamentals with Michael Dong.
In this seventh part of " Conversations with Michael Dong," a series on fundamentals of HPLC in pharmaceutical analysis, LCGC International’s "Perspectives in HPLC" column editor explains why 2.1-mm i.d. columns are less preferred for pharmaceutical quality control.
Ultrahigh-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF-MS) shows how soaking and cooking break down soybean fats.
Nicolai Zederkopff explores chromatography’s role to help implement the maximum tolerable level (MTL) framework for food adulteration to translate analytical results into compliance decisions.
