The development of Proteolysis Targeting Chimeras, or “PROTACs*,” has garnered significant attention in the pharmaceutical industry due to their potential to target and degrade disease-causing proteins previously considered undruggable. As a novel therapeutic modality, PROTACs offer a promising alternative to traditional small-molecule inhibitors and biologics. However, despite the excitement around these therapies, preclinical evaluations of…
Analyzing FDA guidance on DDI studies for therapeutic proteins
The co-administration of drugs is commonplace for therapeutic proteins (TP). Yet, drug developers may face delays or ambiguity in preparing for clinical trials if they don’t plan for preliminary analysis of drug-drug interactions (DDI). Fortunately, the U.S. Food and Drug Administration (FDA) released in August 2020 new draft guidance for DDI assessment of TPs. The…
