Amongst others, the USP published the received comments and responses to General Chapter/Section: <1032> Design and Development of Biological Assays in the Commentary – First Supplement to USP 35-NF 30.

The USP received 13 comments to different parts of this chapter. Comments to the following topics are included:

• Necessary Harmonization with compendial references e.g. European Pharmacopoiea
• Helpful case study examples that illustrate the application
• The need that the assay acheive a specific observable response
• Assessment of similarity using the entire concentration-response curve, including the asymptotes.
• Potency assay for assessment of stability
• Need of documenting the source of assay's cell line

The complete comments can be found at Commentary – First Supplement to USP 35-NF 30.
