E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To characterise the tolerability of Modufolin® in Stage IV CRC patients in terms of toxicity during eight (8) weeks of treatment with one (1) of two (2) dose levels of Modufolin® (30 and 60 mg/m2) in combination either with 5-FU (500 mg/m2) alone (Arm #1), with Oxaliplatin (85 mg/m2) and 5-FU (500 mg/m2) (Arm #2), or with Irinotecan (180 mg/m2) and 5-FU (500 mg/m2) (Arm #3) |
|
E.2.2 | Secondary objectives of the trial |
- To characterise all adverse events (AEs) and clinically significant abnormal laboratory test result changes regardless of attribution during the entire study period. - To evaluate tumour response and disease progression by means of Objective Response Rate (ORR) at the end of study participation. - To assess the level of overall inhibition of thymidylate synthase (TS) as reflected by change of deoxyuridine (dU) levels from before and 24 hours after administration of the combination treatment on Day 1 in Cycle #1 and in Cycle #4 in a subset of patients. - To determine the pharmacokinetic characteristics of methylenetetrahydrofolate (MTHF), methyl-tetrahydrofolate (methyl-THF), and tetrahydrofolate (THF) calculated from plasma samples in each cohort following Modufolin® administration on Day 1 in Cycle #1 and in Cycle #4. |

E.5 End points |
E.5.1 | Primary end point(s) |
