INTRODUCTION: Dilmapimod is a potent p38 mitogen-activated protein kinase (MAPK)
inhibitor and was investigated in a study (NCT00996840) for its anti-inflammatory
effect in non-head injury trauma patients at risk for developing acute
respiratory distress syndrome (ARDS). The purpose of this paper is to present the
details of the development of a population pharmacokinetic (PK) model, an
empirical population placebo response model, and the exploration of a
PK/pharmacodynamic (PD) model of dilmapimod. METHODS: A population PK model was
developed to characterise the PK profile of dilmapimod in this patient
population; the potential effect of available covariates on the PK of dilmapimod
was evaluated. An empirical population placebo response model was conducted, and
a population PK/PD model was explored to evaluate the relationship between
dilmapimod concentration and C-reactive protein (CRP) (a systemic biomarker of
p38 inhibition). All analyses were performed using NONMEM software. RESULTS:
Following intravenous dosing, dilmapimod was quickly distributed to peripheral
compartments and then slowly eliminated. The plasma concentration of dilmapimod
was adequately described by a three-compartment model. It increased approximately
proportionally to the increase in dose. The population clearance (CL) parameter
value was 35.87 L/h, and the steady-state volume of distribution (Vss) [sum of
the volume of distribution of the central compartment (Vc) and of the peripheral
compartments V2 and V3] was 160 L. The effect of body mass index (BMI) on CL and
inter-compartment clearance (Q2) was found statistically significant, with an
increase in BMI of 1 kg/m(2) resulting in a 1.79 L/h and 0.52 L/h increase in CL
and Q2, respectively. The CRP profile post injury was adequately described by an
indirect response model, with a sharp increase in the CRP levels following
injury, followed by them slowly diminishing. Data exploration indicated potential
drug effects of dilmapimod on inhibiting the production of CRP levels; however,
the current small dataset did not show a statistically significant improvement in
the PK/PD modelling. CONCLUSION: The population PK modelling adequately evaluated
the dilmapimod plasma concentration-time profiles in severe trauma subjects at
risk for ARDS, and BMI was found to be a significant covariate in the PK model.
An indirect response model was adequate to describe the production and
degradation of CRP levels in these subjects.
