Which category is NOT one of the main categories of ICH guidelines?

The main categories of ICH guidelines are focused on ensuring that the development and registration of pharmaceuticals are conducted in a manner that is scientifically rigorous, ethically sound, and regulatory compliant. These categories are Quality, Safety, and Efficacy.

Quality guidelines address the aspects of drug development related to the composition, manufacturing, and quality control of pharmaceutical products. Safety guidelines ensure the protection of human subjects and regulatory compliance, focusing on the non-clinical safety evaluation of drugs. Efficacy guidelines relate to the demonstration of the effectiveness of drugs through clinical trials and studies.

Finance does not fall within these primary categories, as it pertains to economic aspects rather than scientific or regulatory requirements. Therefore, it is not part of the ICH framework which is centered around the principles that govern drug development and approval processes.
