Methods: Patients were enrolled in cohorts of one to three to receive escalating dose of PEP02 in a phase I trial. PEP02, from 60 to 180 mg/m2, was given as a 90-min intravenous infusion, every 3 weeks. Results: A total of 11 patients were enrolled into three dose levels: 60 (one patient), 120 (six patients) and 180 mg/m2 (four patients). DLT was observed in three patients, one at 120 mg/m2 (grade 3 catheter-related infection) and two at 180 mg/m2 (grade 4 neutropenia lasting for >3 days in one, grade 4 hematological toxicities and grade 4 diarrhea in the other). MTD was determined as 120 mg/m2. Comparing with those after free-form irinotecan in the literature, the dose-normalized PK of SN-38 (the active metabolite) after PEP02 was characterized by lower C max, prolonged terminal half-life and higher AUC but with significant inter-individual variation. One patient who died of treatment-related toxicity had significantly higher C max and AUC levels of SN-38 than those of the other three patients at 180 mg/m2. Post hoc pharmacogenetic study showed that the patient had a combined heterozygosity genotype of UGT1A1?6/?28. Two patients had objective tumor response. Conclusions: PEP02 apparently modified the PK parameters of irinotecan and SN-38 by liposome encapsulation. The MTD of PEP02 monotherapy at 3-week interval is 120 mg/m2, which will be the recommended dose for future studies. ? 2015 The Author(s). |
