| ID | NME | Year of approval | Detail of predicted scenarios | Simulation results | Impact / outcome | Referencesa |
|---|---|---|---|---|---|---|
| 21 | Alectinib | 2015 | Timing of food on alectinib exposureb | Less than 20% change predicted | PBPK model not reviewed because no obvious exposure‐response relationship identified | 27450228 |
| 22 | Ceritinib | 2014 | Food effect | Cmax change matched observation but AUC did not | No direct labeling impact, FDA exploratory simulations | |
| Effect of gastric pH change | Cmax and AUC decrease by 10% | |||||
| P‐gp contribution to intestinal absorption | Appeared to be minimal | |||||
| 23 | Ibrutinib | 2013 | Food effect to explain different exposure between healthy and oncology subject | Pharmacokinetic differences ascribed to type and timing of food on hepatic/intestinal blood flow rate | No direct labeling impact | |
| Intestinal exposure prediction | Dose staggering could lower the risk of P‐gp‐mediated DDI | |||||
| 24 | Naloxegol | 2014 | P‐gp contribution to intestinal absorption | Appeared to be minimal | No direct labeling impact | 27299937 |
| 25 | Panobinostat | 2015 | Effect of gastric pH changec | Minimal effect predicted (no change in the fraction of a drugs absorbed up to the gastric pH of 8.0) | Label states no ARA effect observed in simulation | |
| 26 | Sonidegib | 2015 | Food effect | Significant underestimation compared to clinical data | No direct labeling impact, FDA exploratory simulations |
