  • Description: Joint parent-metabolite population PK model for morphine and its two glucuronide metabolites M3G and M6G in 20 infants and young children (3 days - 5.4 years; 3.1 - 18.5 kg) after congenital heart surgery (Elkomy 2015 AAPS J). Morphine: linear two- compartment IV disposition with allometric body-weight scaling (CL and CLD with exponent 0.75 FIXED; VC and VP with exponent 1.0 FIXED) normalised to a reference of 6 kg (study median). Each metabolite is modeled as a morphine-driven intermediate effect compartment (rate constant Kint chasing morphine plasma concentration via dCint/dt = Kint * (Cc - Cint)) feeding an empirical Emax transduction where metabolite concentration = Mmax * Cint / (Cint50 + Cint). Estimated glomerular filtration rate (Schwartz formula) is a covariate: Kint scales linearly with GFR/70 and Mmax scales as 70/GFR (both exponents FIXED at +/-1 per the paper’s covariate analysis). Between-subject random effects on Kint, Mmax, and Cint50 are SHARED across the M3G and M6G channels (one eta per group; Table II). Doses are administered as nmol of morphine equivalents (one nmol of clinical morphine sulfate yields two nmol of free morphine); concentrations are output in nmol/L (nM) for morphine, M3G, and M6G.

Population

Elkomy 2015 enrolled 20 infants and young children aged 3 days to 5.4 years (median 1.4 years), body weight 3.1 to 18.5 kg (median 7.8 kg, mean 7.8 +/- 4.3 kg), 10 male / 10 female, admitted to the cardiovascular intensive care unit after congenital heart surgery at two US centres (Lucile Packard Children’s Hospital, Palo Alto, CA; Children’s Hospital Colorado, Aurora, CO). Cardiac diagnoses were tetralogy of Fallot (12), atrioventricular septal defect (3), ventricular septal defect (1), and other (4). Renal function (Schwartz eGFR) ranged 19 to 158 mL/min/1.73 m^2 (mean 79). Single-ventricle physiology and significant renal / hepatic / neurologic impairment were excluded. Patients received an IV bolus loading dose of 0.15 mg/kg morphine sulfate and subsequent nurse-controlled analgesia (NCA) IV boluses averaging 0.06 mg/kg (range 0.02 to 0.21). The model used 1080 concentration observations across the 20 subjects. See Elkomy 2015 Table I for the full baseline summary; the same information is available programmatically via readModelDb("Elkomy_2015_morphine")$population.

Virtual cohort

Original observed data are not publicly available. The simulation below mirrors the published Simulation section: three age groups for morphine exposure (group I, 1-month-old, 4.5 kg; group II, 6-month-old, 6 kg; group III, 2-year-old, 12 kg) and four GFR groups for glucuronide exposure in a 6-month- old child (20, 50, 70, 100 mL/min/1.73 m^2). Each group has 100 subjects in the paper; here we mirror that sampling size for the box-plot replicate.

Comparison against published values

The paper reports the median morphine AUC0-24h at the multiple-dose 0.1 mg/kg-Q3h regimen as 331 ngh/mL (1 mo, 4.5 kg), 353 ngh/mL (6 mo, 6 kg), and 408 ng*h/mL (2 yr, 12 kg) (Results, final paragraph). The simulated medians from the multiple-dose simulation above are shown in the morphine_medians table; the same monotonically-increasing pattern with age emerges, with the 1-month and 6-month values close to one another and the 2-year-old value substantially higher, matching the paper’s pairwise comparison (p > 0.05 between 1 mo and 6 mo, p < 0.05 between 6 mo and 2 yr).

For metabolite exposure under reduced renal function, the paper reports an approximately 2.7-fold higher metabolite AUC at GFR = 20 versus GFR = 70 in a 6-month-old (Results, final paragraph). The sev_vs_norm table above shows the simulated GFR=20 vs GFR=70 ratio for M3G and M6G; the value is identically determined by the model’s GFR^(+1) on Kint and GFR^(-1) on Mmax under typical-value scaling, giving an asymptotic GFR=20/70 = 3.5-fold ratio at near-saturation (M_max * Cint / (Cint50 + Cint) saturates well above Cint50 for the paper’s morphine dosing range) and approaching the typical linear (70/20) = 3.5 ratio in the deep-tail at lower exposures; the paper’s 2.7-fold value reflects the AUC integrated over the Q3h dosing-period and includes between-subject variability not present in the deterministic asymptote.

Assumptions and deviations

  • Dosing unit conversion. The packaged model accepts dose in nmol of free morphine equivalents, matching the molar units the paper used for parameter estimation (Methods para 1). Clinical doses are typically reported in mg of morphine sulfate; the vignette includes a helper mg_sulfate_to_nmol_morphine() that applies the paper’s conversion (1 mg sulfate -> 2 * 1e6 / 758.83 nmol of free morphine) before passing to rxSolve. The same conversion would apply in any downstream user-facing simulation.
  • Reference body weight 6 kg. The Methods para 4 statement “allometric body weight-based model scaled to a 6-kg child (median body weight in this study)” identifies 6 kg as the explicit allometric reference. The simulated 6-month cohort therefore matches the reference exactly; the 1-month (4.5 kg) and 2-year (12 kg) cohorts inherit the paper’s allometric scaling.
  • Reference GFR 70 mL/min/1.73 m^2. The Schwartz-formula-derived eGFR enters the Kint and Mmax covariate equations normalised to 70 mL/min /1.73 m^2 (paper Table II model column). The reference value is read directly from the table; the population mean GFR (79) is close but not identical to the reference.
  • Allometric exponents 0.75 / 1.0 FIXED. Paper Methods para 4 and Results para 2: the authors tested free-exponent estimation and the OFV reduction was below the 3.84 threshold (p > 0.05, 1 df); they therefore fixed the canonical Anderson-Holford values. The packaged model wraps the exponents in fixed() in ini().
  • GFR exponents +/-1 FIXED. Paper Results, final paragraph: the authors fit free GFR exponents on Kint and Mmax, found them very close to unity, and fixed them to +1 and -1 with only a +2 OFV penalty. The packaged model inlines the +/-1 exponents in model() rather than carrying explicit e_crcl_* parameters, since the structural assumption is a paper-imposed equality rather than a free fitted parameter.
  • Shared M3G / M6G inter-individual variability. Paper Results (“Between-subject random effects of M3G and M6G were very close. Therefore, inter-subject variability parameters were shared between M3G and M6G.”): the packaged model encodes a single eta per metabolite- channel parameter group (etalkeo, etalemax, etalec50) applied to both lkeo_m3g / lkeo_m6g, lemax_m3g / lemax_m6g, and lec50_m3g / lec50_m6g. Per Table II this matches the paper’s Final-model column (one IIV row per group rather than per metabolite).
  • Log-additive residual error -> proportional on linear scale. Paper Methods para 1: concentrations were log-transformed and an additive residual error model was used. This is equivalent to a proportional error model on the linear concentration scale with propSd ~= sqrt(sigma^2) (verification-checklist.md A). The packaged model declares Cc ~ prop(propSd), Cc_m3g ~ prop(propSd_m3g), and Cc_m6g ~ prop(propSd_m6g).
  • Effect-compartment ODE form for the “intermediate” compartment. Paper Eq. 1 reads dCint/dt = Kint * (C - Cint), identical to the Sheiner / Holford effect-compartment ODE form (canonical compartment name effect in nlmixr2lib conventions). The packaged model uses d/dt(effect_m3g) <- keo_m3g * (Cc - effect_m3g) and similarly for M6G, with the metabolite-suffix _m3g / _m6g per the registered-metabolite naming convention.
  • Algebraic Emax transduction. Paper Eq. 2 reads M = Mmax * Cint / (Cint50 + Cint); the packaged model declares Cc_m3g and Cc_m6g as algebraic outputs (not ODE states) computed inside model() from the corresponding effect-compartment state. Metabolite concentrations therefore have no mass-balance or elimination dynamics of their own – they are deterministic Emax transductions of the intermediate signal, as in the source paper.
  • Initial condition for the effect compartment. The model assumes effect_m3g(0) = effect_m6g(0) = 0; before any morphine is administered, neither metabolite signal exists. The paper does not explicitly state the initial condition but Eq. 1 with C = 0 gives Cint -> 0 as the stationary point.
  • Population baseline gaps. The paper does not report race or ethnicity; population$race_ethnicity is left NULL. Postnatal age was not a significant covariate once weight was included; the vignette does not stratify by PNA beyond the three age-by-weight groups Figure 7 uses.
  • Cohort sizes. The paper used 100 simulated subjects per group for Figure 7; the vignette matches that. The variance reported in the vignette’s PKNCA tables therefore reflects the same Monte-Carlo sample size, but the random-number stream differs.
