Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
CPT-11+ Folinic Acid+ 5FU weekly for 6 weeks on days 1,8,15,22,29 and 36 (followed by 2 weeks rest for a total cycle duration of 8 weeks) at the following doses:
CPT-11: 80 mg/m2 in 250 ml normal saline intravenous injection (IV) over 90 minutes
Folinic acid: 200 mg/m2 in 500 ml normal saline IV over 2 hours
5FU: 450 mg/m2 IV bolus.

This 8-week cycle will be administered in an identical manner again (i.e. total 16 weeks).

Then, it will be followed by Oxaliplatin+ Folinic Acid+ 5FU weekly for 6 weeks on days 1,8,15,22,29 and 36 (followed by 2 weeks rest for a total cycle duration of 8 weeks) at the following doses:
Oxaliplatin: 45 mg/m2 IV over a 90 min infusion
Folinic acid: 200 mg/m2 in 500 ml normal saline IV over 2 hours
5FU: 450 mg/m2 IV bolus

This 8-week cycle will be administered in an identical manner again (i.e. total 16 weeks).

The overall duration of the intervention will be 32 weeks in total (4 cycles).

Treatment: Drugs
Comparator / control treatment
CPT-11+Folinic Acid+5FU weekly for 6 weeks on days 1,8,15,22,29 and 36 (followed by 2 weeks rest for a total cycle duration of 8 weeks) at the following doses:
CPT-11: 80 mg/m2 in 250 ml normal saline intravenous injection (IV) over 90 minutes
Folinic acid: 200 mg/m2 in 500 ml normal saline IV over 2 hours
5FU: 450 mg/m2 IV bolus.

Folinic acid and 5FU will be given immediately after completion of CPT-11 infusion. Each course should be repeated every week for 6 weeks followed by a two week rest period. One cycle represents 6 infusions (8 weeks).

4 cycles in total will be undertaken over a duration of 32 weeks.

Summary
Brief summary
The aim of this study was to compare the response rate (RR), progression free survival (PFS) and overall survival (OS) and to assess the toxicity profile of previously untreated patients with advanced colorectal cancer (CRC) randomly assigned between Camptothecin-11 (CPT-11)/5FU /Folinic Acid (arm A) versus Camptothecin-11 (CPT-11)/Fluorouracil (5FU)/Folinic Acid followed by Oxaliplatin/Fluorouracil (5FU)/Folinic Acid(arm B) in the same line of treatment.
A theoretical framework supports the hypothesis that the sequential administration of cytotoxic drugs at adequate doses can maximize the cell kill and overcome drug resistance.
