In recent years the interest in antibody drug conjugates for the targeted treatment of various cancer types has grown massively, and the need for evaluation of the pharmacokinetic profile of these ADCs is becoming more important. Radiolabelling of drugs remains the most effective methodology to facilitate absorption, distribution, metabolism and excretion (ADME) studies, and therefore [14C] labelling of ADCs is becoming a critical part of their development. The [14C] label is typically placed on either the active drug or the linker moiety, or can be incorporated into both.

Almac’s expertise in this area comes from the integration of biology, chemistry, peptide and purification science, analytical and quality disciplines within their isotope laboratories. The ability to deliver labelled linkers, payloads and complete the bioconjugation within one team shortens timelines and results in a more cost effective solution to clients.
