Abstract 2488


Variability of PTX exposure using BSA dosing is well documented and often leads to severe toxicities. While carboplatin is dosed to obtain a specific exposure, paclitaxel is conventionally dosed by BSA, leading to a wide range of exposure. This study compared PTX PK-guided dosing to BSA dosing in a PTX-carboplatin regimen treating stage IIIB/IV NSCLC. This is the final analysis of interim results presented at ASCO 2015 (Poster #375). ClinicalTrials.gov Identifier NCT02058433.


309 patients with stage IIIB/IV NSCLC were randomized to receive up to 4 cycles of first line 3-weekly carboplatin (AUC 5) and a PTX dose of 175 mg/m2 (Arm A), or a PTX PK-guided dose (Arm B) to achieve a time above a PTX plasma concentration of 0.05µM (Tc>0.05) for 26 to 31 hours. Response was classified according to Response Evaluation Criteria in Solid Tumors Group. PTX concentrations were measured by immunoassay; Tc>0.05 was calculated with PK software. The primary endpoint was reduction of grade 4 hematological toxicities.


There were 164 patients in Arm A and 155 patients in Arm B, with 191 males and 128 females participating. PK-guided dose adjustment resulted in doses that were widely distributed 73 – 175 mg/m2, and statistically lower than in the BSA arm (by 24%, p 


Results of this study are in agreement with a previous report, and present further evidence that PK-guided dosing reduces severe toxicities. This is accomplished by an overall lowering of dose intensity, while still maintaining efficacy. PK-guided dosing personalizes chemotherapy, and may be useful in patient management.
