The model is a joint two-compartment parent + two-compartment metabolite population PK model fitted simultaneously to gemcitabine and its inactive metabolite 2’,2’-difluorodeoxyuridine (dFdU) in 94 adult patients with cancer pooled from three Australian clinical trials (Methods, page 327; Table 1). Gemcitabine is administered as a 30-min or 100-min IV infusion; the dose elimination from the gemcitabine central compartment is treated as the apparent formation flux into the dFdU central compartment because the fraction-of-conversion F is not identifiable from plasma data (page 329, “The fraction of conversion (F) from gemcitabine to dFdU could not be independently estimated and hence apparent values of Q_dFdU/F, CL_dFdU/F, V_C,dFdU/F and V_P,dFdU/F are reported”). Page 330 gives the final covariate equations:
CL_dFdU/F (L/min) = 0.04 * (1 + 0.48 * CRCL/70)
V_C,dFdU/F (L) = 46 * (BSA/1.73)^0.93 * 0.65^GEMOX * 0.54^OXGEM * 1.24^NSCLCPopulation
The pooled cohort comprises 94 adult patients with cancer across three clinical studies (Study 1: open-label Phase I dose-escalation, n=21, diverse tumour types, gemcitabine-then-oxaliplatin; Study 2: randomised Phase II sequencing trial, n=43, advanced NSCLC, gem-then-ox vs ox-then-gem; Study 3: randomised crossover, n=31, diverse tumour types, 30-min vs 100-min gemcitabine infusion without oxaliplatin). Baseline demographics from Table 2: age 33-85 years (median 65), body weight 37-120 kg (median 73), body surface area 1.2-2.5 m^2 (median 1.8), estimated creatinine clearance 37-150 mL/min (median 83), 68 male and 26 female. Tumour-type split: NSCLC 47, pancreatic 14, diverse 33. Oxaliplatin sequence split: 31 gemcitabine alone, 38 gemcitabine- then-oxaliplatin, 25 oxaliplatin-then-gemcitabine. Concentration data: 652 plasma gemcitabine and 1130 plasma dFdU samples across 122 PK profiles (HPLC-UV at 272 nm; LOQ 0.2 mg/L for both analytes; page 328).

Virtual cohort
Original observed data are not publicly available. The cohort below
uses 300 virtual patients distributed across the three regimen groups
(100 gemcitabine alone, 100 gem-then-ox, 100 ox-then-gem) with body
surface area, creatinine clearance, and NSCLC indicator distributions
that bracket the published Table 2 demographics. Each patient receives a
single gemcitabine 1250 mg/m^2 30-min IV infusion (the modal Study 1 /
Study 2 dose); the absolute mg dose is computed per subject as
1250 * BSA.

Figure 5 – gemcitabine concentration-time profile
Replicates Figure 5 of Jiang 2008 (predictive check of gemcitabine over the 0-200 min window). The plot shows 5th, 50th, and 95th percentiles of the stochastic simulation against time, by regimen. Gemcitabine disposition is unaffected by the dFdU covariates (oxaliplatin order and tumour-type indicators only affect V_C,dFdU/F), so all three regimens should overlay closely.

Figure 6 – dFdU concentration-time profile
Replicates Figure 6 of Jiang 2008 (dFdU predictive check, 0-2000 min). The figure axes in the paper span up to 100 mg/L on a log scale and out to ~1500 min in time. Unlike gemcitabine, dFdU disposition is sensitive to the oxaliplatin-sequence indicators (V_C,dFdU/F decreased by 35% when GEMOX=1, 46% when OXGEM=1) and the NSCLC indicator (V_C,dFdU/F increased by 24% when NSCLC=1), so per-regimen overlays should diverge in early-phase peak height.

one for the dFdU metabolite Cc_dfdu. Each carries the

)Comparison against published parameter values
Jiang 2008 does not tabulate NCA summaries (Cmax, AUC, half-life) per regimen – the published comparison is instead a visual predictive check (Figures 5 and 6) plus the per-parameter table (Table 3). Below is a sanity check that the typical-value gemcitabine clearance recovered by the simulation matches the published CL_gem = 2.7 L/min within the expected NCA approximation uncertainty.

Assumptions and deviations
-
Between-occasion variability (BOV) is not encoded.
Jiang 2008 Table 3 reports BOV on CL_gem (12% CV), V_C,gem (93% CV),
CL_dFdU/F (11% CV), and V_C,dFdU/F (10% CV) in addition to the BSV
values. nlmixr2 has no native occasion-level random-effect slot for a
static model definition, so only BSV is encoded in
ini(). Users fitting the model to multi-cycle data should consider adding an occasion-level eta layer externally. - NSCLC prevalence by regimen approximated from Table 1. The paper does not publish a 3 x 2 contingency of regimen x NSCLC; the virtual cohort above uses Study 2 (NSCLC-only) + Study 1 (diverse tumour types, gem-then-ox) + Study 3 (diverse tumour types, gemcitabine alone) to set per-regimen NSCLC prevalences at 10% / 55% / 100% respectively. The structural model is unaffected by this choice.
- Demographics distributions approximated. Body surface area and creatinine clearance distributions are sampled from log-normal curves whose median bracket Table 2’s published medians; the actual cohort distribution is unknown from the paper.
- Cmax / AUC NCA comparison. Jiang 2008 reports a visual predictive check (Figures 5 and 6) and Table 3 parameter estimates rather than tabulated NCA values per regimen. The comparison section above therefore checks the apparent clearance recovered from the simulation against the published CL_gem = 2.7 L/min as a sanity check rather than rendering a full ncaComparisonTable.
-
dFdU
kelis the apparent elimination rate. The dFdU parameters (CL_dFdU/F, V_C,dFdU/F, etc.) are all apparent values because the fraction-of-conversion F from gemcitabine to dFdU is not identifiable (page 329). The simulated dFdU concentrations are nevertheless on the real plasma scale because the F factor cancels inconcentration = mass/F / volume/F = mass/volume. - Allometric / size scaling not included. Body weight was screened during covariate development but not retained (page 330, “No other covariates … investigated in this study were identified as having a significant impact”). The final model uses BSA (on V_C,dFdU/F only) rather than weight as the body-size descriptor.
