Summary of Clinical Use
Acelarin is in clinical trial in the ProGem1 phase I study, for the treatment of advanced solid tumours.
Mechanism Of Action and Pharmacodynamic Effects
To become an active antimetabolite, gemcitabine must be sequentially phosphorylated to the mono-, bi- and finally tri-phosphate forms (dFdCMP, dFdCDP and dFdCTP respectively). Adding the phosphoramidate effectively pre-phosphorylates the gemcitabine avoiding the first essential and rate-limiting phosphorylation step normally requiring deoxycytidine kinase (DCK, P277072]. In sum, the acelerin nucleoside has more effective antimetabolite activity than gemcitabine [1-2] and is already proving more efficacious in the clinical setting.
