Irinotecan With or Without Panitumumab or Cyclosporine in Treating Patients With Advanced or Metastatic Colorectal Cancer That Did Not Respond to Fluorouracil
A Phase 3 study testing panitumumab, cyclosporine and irinotecan hydrochloride in people with Colorectal Cancer, run by University of Leeds at 33 sites in United Kingdom.
Trial summary
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cyclosporine may help irinotecan work better by making tumor cells more sensitive to the drug. Read more about this study

About this study
Official title: A Randomised Clinical Trial of Treatment for Fluorouracil-Resistant Advanced Colorectal Cancer Comparing Standard Single-Agent Irinotecan Versus Irinotecan Plus Panitumumab and Versus Irinotecan Plus Ciclosporin [Panitumumab, Irinotecan & Ciclosporin in COLOrectal Cancer Therapy (PICCOLO)]
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cyclosporine may help irinotecan work better by making tumor cells more sensitive to the drug. Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Panitumumab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether irinotecan is more effective when given with or without panitumumab or cyclosporine in treating colorectal cancer.
PURPOSE: This randomized phase III trial is studying irinotecan to compare how well it works when given with or without panitumumab or cyclosporine in treating patients with advanced or metastatic colorectal cancer that did not respond to fluorouracil.
Read the detailed description
OBJECTIVES:
Primary
- Compare the efficacy and toxicity of single-agent irinotecan hydrochloride (Ir) vs Ir with cyclosporine (IrC) in patients with fluorouracil-resistant advanced colorectal cancer.
- Compare the efficacy of single-agent Ir vs Ir with panitumumab (IrP) in these patients.
Secondary
- Correlate the toxicity of Ir and/or IrC with genetic variability in the enzymes involved in irinotecan hydrochloride's disposition pathway.
- Compare IrC to Ir and its metabolites (SN38; SN38G), in terms of pharmacokinetic profile.
- Correlate the benefit of IrP with tumor expression of epidermal growth factor receptor (EGFR) or its known down-stream molecules as a predictive measure.
- Correlate IrP efficacy or toxicity (specifically the severity of skin rash) with somatic alterations in the EGFR gene and/or with germline variability in related genes.
OUTLINE: This is a randomized, open-label, controlled, multicenter study. Patients are stratified according to prior cetuximab (yes vs no). Patients are randomized to 1 of 3 treatment arms.
- Arm I: Patients receive irinotecan hydrochloride IV over 30-90 minutes on day 1.
- Arm II: Patients receive irinotecan hydrochloride IV over 15-40 minutes on day 1 and oral cyclosporine three times a day on days 1-3.
- Arm III: Patients receive panitumumab IV over 30-90 minutes followed by irinotecan hydrochloride IV over 30-90 minutes on day 1. Single-agent panitumumab may be continued during breaks in chemotherapy treatment.
In all arms, treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with responding or stable disease may continue treatment in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline and at 12 and 24 weeks.
After completion of study treatment, patients are followed every 12 weeks for 1 year.

PROJECTED ACCRUAL: A total of 1,269 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing panitumumab, cyclosporine and irinotecan hydrochloride in people with Colorectal Cancer, run by University of Leeds at 33 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 33 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of patients treated with irinotecan hydrochloride (Ir) alone vs Ir and cyclosporine (IrC) who are progression-free at 12 weeks. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00389870, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2022.
