IXO (Irinotecan, Xeloda, Oxaliplatin) in Rectal Cancer (IXOr)

October 12, 2012 updated by: Ottawa Hospital Research Institute

A Phase II Trial of Neoadjuvant IXO Regimen (Irinotecan, Capecitabine [Xeloda], Oxaliplatin) Followed by Combined Modality Capecitabine and Radiation for Locally Resectable Advanced Rectal Cancer

This is a prospective open label single-arm, single-institution phase II clinical trial to test the efficacy of neoadjuvant treatment with IXO (Irinotecan, Capecitabine [Xeloda], Oxaliplatin) followed by chemoradiotherapy and resection in patients with resectable non-metastatic primary rectal cancer of stage cT3-T4 N0-N2.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: IXO regimen
single-group
Drug: IXO regimen

IXO regimen is administered as following: irinotecan 160 mg/m2 i.v. (over 60-90 minutes) with oxaliplatin 100 mg/m2 i.v. (over 120 minutes) on day 1, followed by capecitabine 950 mg/m2 PO, b.i.d. on days 2-15, every 3 weeks.

Each cycle of IXO lasts 21 days, with the subsequent cycle to start on day 22.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
