Dose Escalation Study of Lithium With Oxaliplatin and Capecitabine in Advanced Oesophago-Gastric or Colorectal Cancer

This study is a phase Ib, open label, multi-centre trial designed to estimate the Maximum Tolerated Dose (MTD) of lithium when combined with a standard chemotherapy regimen of oxaliplatin and capecitabine in patients with advanced, unresectable, oesophago-gastric or colorectal cancer who have received no previous treatment for advanced disease (previous adjuvant or neo-adjuvant treatment is acceptable if completed at least 6 months prior to registration).
The study follows a modified Fibonacci, 3+3, dose escalation design. Patients are enrolled in cohorts of 3. All three patients in each cohort must complete at least two cycles of treatment to be evaluable for toxicity. If a patient cannot complete 2 cycles, another patient will be enrolled.
