Neutropenia is a condition in which neutrophils are below normal levels. It is a common side effect in cancer patients treated with chemotherapy and is associated with an increased risk of getting serious infections. Chemotherapy-induced neutropenia is of primary concern for both drug developers and clinicians, as in order to prevent its occurrence, chemotherapy doses may be lowered or delayed, possibly compromising treatment outcomes (Lustberg 2012). 

CTx NeutroSim is based on a semi-mechanistic pharmacokinetic/pharmacodynamic computational model which describes neutropenic effects following the administration of a chemotherapeutic agent. The computational model has been calibrated on data obtained from diflomotecan clinical trials and demonstrated its ability in describing neutropenic effects after very different dosing schedules of diflomotecan given either by intravenous infusion or oral administration (Mangas-Sanjuan 2015).   

CTx NeutroSim enables simulations of clinical trials on a virtual population of cancer patients being treated with a chemotherapeutic drug. The tool can be used to explore different trial design scenarios in terms of drug pharmacokinetic and pharmacodynamic properties, single and multiple dosing, administration route, as well as virtual population.
