Metronomic Capecitabine, Oxaliplatin and UGT1A1 Genotype-directed Irinotecan in Metastatic Pancreatic Cancer Patients
Sponsor: National Cancer Centre, Singapore
Summary
This is a single-centre, non-randomized, open label phase II trial to be conducted at the National Cancer Centre, Singapore (NCCS). Patients diagnosed with metastatic PDAC will be eligible to enrol. The investigators hypothesize the anticancer activity of low dose OXIRI (LD-OXIRI) regimen comprising of metronomic oxaliplatin (O) and metronomic capecitabine (xeloda; X) in combination with UGT1A1-directed dosing of irinotecan (IRI) to be a tolerable regimen in patients with advanced PDAC and will lead to a favourable response rate. Patients will be prospectively enrolled in two stages - In stage 1, patients will be recruited and evaluated for response and toxicity. In stage 2, more patients will be recruited for further evaluation of response and toxicity.
Official title: A Phase II Study of Metronomic Capecitabine, Oxaliplatin and UGT1A1 Genotype-directed Irinotecan in Metastatic Pancreatic Cancer Patients.

Low Dose OXIRI (LD-OXIRI)
The LD-OXIRI regimen will be administered in the following sequence: * metronomic capecitabine (Xeloda; X) 650mg/m2 will administered twice a day on a daily a continuous basis; * intravenous metronomic oxaliplatin (O) 50 mg/m2 will be infused over 120 minutes on days 1 and 8 of a 21 day-cycle; followed by * intravenous irinotecan (I) will be infused over 90 minutes on days 1 and 8 of a 21 day-cycle. The dose of irinotecan will be based on the particular patient's UGT1A1\*6 and UGT1A1\*28 genotype status.
