Potency can be described as the quantitative measure of biological activity, that is, the ability of an Advanced Therapy Medicinal Product (ATMP) to elicit the intended effect necessary for clinical efficacy. Potency testing is part of the quality control strategy necessary for batch release and is required for market approval application of an ATMP. Thus, it is crucial to develop a reliable and accurate potency assay. As a prerequisite for potency assay development, it is essential to define the mode of action of the product and thereby also the relevant biological activity that should be measured. The establishment of a potency assay should be initiated already during early product development followed by its progressive implementation into an ATMP's manufacturing, quality control and release process. Potency testing is indispensable for clinical use with a wide range of applications. A potency assay is a valuable tool to determine the product's stability, detect the impact of changes in the manufacturing process on the product, demonstrate quality and manufacturing consistency from batch to batch, estimate clinical efficacy and define the effective dose. This chapter describes the requirements and challenges to be considered for potency assay development and the importance of a well-established potency assay for clinical use.

Background: Several chemical studies described the physiological efficacy of 1,4- dihydropyridines (DHPs). DHPs bind to specific sites on the α1 subunit of L-type calcium channels, where they demonstrate a more pronounced inhibition of Ca2+ influx in vascular smooth muscle compared to myocardial tissue. This selective inhibition is the basis for their preferential vasodilatory action on peripheral and coronary arteries, a characteristic that underlies their therapeutic utility in managing hypertension and angina.

Histone lysine-specific demethylase 1 (LSD1) is overexpressed in various solid and hematological tumors, suggesting its potential as a therapeutic target, but there are currently no LSD1 inhibitors available on the market. In this study we employed a computer-guided approach to identify novel LSD1/EGFR dual inhibitors as a potential therapeutic agent for non-small cell lung cancer. Through a multi-stage virtual screening approach, we found L-1 and L-6, two compounds with unique scaffolds that effectively inhibit LSD1 with IC values of 6.

Small molecule degraders such as PROteolysis TArgeting Chimeras (PROTACs) and molecular glues are new modalities for drug development and important tools for target validation. When appropriately optimized, both modalities lead to proteasomal degradation of the protein of interest (POI). Due to the complexity of the induced multistep degradation process, controls for degrader evaluation are critical and commonly used in the literature.
