Abstract
Aims: To investigate the safety profile, dose-limiting toxicity and antitumor activity of PEP503 (NBTXR3) nanoparticles with radiotherapy and concurrent chemotherapy in patients with locally advanced or unresectable rectal cancer. Methods: Patients will receive a single intratumoral injection of the nanoparticles, followed by radiotherapy and intravenous infusion of fluorouracil or oral capecitabine concurrently. In phase Ib (escalation phase, 3 + 3 design), volume escalation is based on the tumor volume of 5, 10, 15 and 22% of total baseline tumor volume. In phase II (expansion phase), 18 additional patients will be enrolled. Discussion: This study will be the first prospective, open-label, single-arm, nonrandomized study to investigate the efficacy and safety profile of PEP503 (NBTXR3) nanoparticles with radiotherapy and chemotherapy in these patients. Trial registration number: NCT02465593 (ClinicalTrials.gov).
