In my previous blog, I spoke about the FDA recall of angiotensin II receptor blockers like losartan. This recall was due to the presence of genotoxic nitrosamines.
Is a proactive approach the way to mitigate risk?
Recently, the FDA has re-issued the 2018 guidance to industry, “M7(R1) assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk”. Is this going to help? Or should we have a higher focus of qualitative analysis up front?
Companies need to take a look all facets of their supply chain and manufacturing process. They should be able to ensure they can control the active pharmaceutical ingredients (APIs) throughout the process, whether they do it in their own facility or it is outsourced.
How are they going to do this?
Why you need a control strategy
A control strategy is a planned set of controls derived from current product and process understanding that assures process performance and product quality (ICH Q10, Ref. 8).
A control strategy can include, but is not limited to, the following:
How to ensuring better data, by seeing it all
Work previously presented by Prof. Sörgel, at the Institute for Biomedical and Pharmaceutical Research, Nuremberg, Germany on the benefits of this workflow is that with SWATH® Acquisition you are creating a digital record of all the analytes in the sample.
This approach shows:
Watch out for our next blog where we examine some of the analytical challenges of these molecules.You can learn more about how LC-MS/MS solutions can identify, quantify and monitor the required levels of nitrosamine impurities by accessing technical notes and a webinar addressing the characterization and quantification of the genotoxic impurities.

This is part two of an ongoing blog series on genotoxic analysis. Read part one: “What have we learned from the nitrosamine crisis?” and part three: “Developing a method for nitrosamine analysis in pharmaceutical products“.

Finding the right information shouldn’t slow you down. Whether you’re troubleshooting your mass spec, learning something new, or optimizing performance, access to the right resources at the right moment makes all the difference.
As an analytical strategy, middle-down mass spectrometry (MS) workflows characterize biotherapeutic proteins by analyzing large, digested protein fragments or defined subunits, rather than fully intact proteins (top-down) or digested peptides (bottom-up). A middle-down strategy combines the strengths of top-down and bottom-up approaches by delivering high sequence coverage and structural specificity while maintaining relatively simple sample preparation. In practice, middle-down analysis enables accurate mass measurement, rapid sequence confirmation, and localization of key post-translational modifications (PTMs) on protein subunits that are directly relevant to product quality.
In biopharmaceutical development, sequence variants (SV) are considered an inherent risk of producing complex proteins in living systems. Sequence variants are unintended changes to the amino acid sequence of a biotherapeutic and can be caused by errors in transcription or translation in the host cell, or cell culture and process conditions. Detailed analysis of SVs is important in process and product development to ensure the drug’s safety and efficacy. Even low‑level sequence variants can have significant implications for product quality, safety, and efficacy, making their accurate detection and characterization a critical requirement across development, process optimization, and regulatory submission.
