Study Summary

  • Study design: phase III, randomised controlled, two arm, multi-centre, non-inferiority

  • Study treatment:

  • Study recruitment: 9500 patients over 5 years (150 sites in the UK)

  • Study population: patients with colorectal cancer

  • Timelines:

  • - Recruitment started in March 2008

  • - Planned accrual completion is March 2013

  • - Trial analysis and publication planned for 2016

  • - Trial duration of 7 years



Objectives & Endpoints

  • Objectives

  • Assessment of the efficacy of 12 weeks of treatment vs 24 weeks of treatment and comparison of the associated toxicity

  • Economic analysis to assess the cost-effectiveness of the two treatment alternatives

  • Comparison of two randomisation methodologies

  • Endpoints

  • Primary Endpoint:

  • - Disease free survival (3 year)

  • Secondary Endpoint:

  • - Overall survival

  • - Cost-effectiveness

  • - Toxicity

  • - Quality of life



Site Registration Process

  • All sites will be randomised to Upfront Randomisation after a decision made by the Trial Steering Committee (June 2009)

  • - Upfront: Randomisation at commencement of adjuvant treatment to either 24 or 12 weeks of chemotherapy

  • Prior to June 2009 some sites were randomised to the delayed randomisation time point.

  • - Delayed: Randomisation after 12 weeks of adjuvant treatment to either stopping, or continuing with a further 12 weeks of chemotherapy



Site Registration Process

  • From the outset of the trial it was specified that a decision would be made in relation to the 2 randomisation time points approx 1 year after the study opened to recruitment.

  • The independent members of the TSC decided that the study should continue with upfront randomisation time point only for the remaining duration of the trial.

  • Reason for Amendment to Randomisation

  • The decision was based on the data presented in the first interim analysis report.

  • The data showed a 32% drop out rate of patients prior to the delayed week 12 randomisation, compared to a 7% dropout of patients stopping treatment before completing 12 weeks of treatment on the upfront randomisation arm.



Upfront



Site Registration Process

  • Prior to site activation, a site questionnaire will need to be completed. The questionnaire will require the following information:

  • - List of all the sites that the PI is responsible for and which are going to participate in SCOT.

  • - Responsible CTU for your site.

  • - Which sites are willing to participate in the QoL questionnaires.

  • - Estimate the total annual recruitment for all the listed hospitals.

  • Return the questionnaire to CTU Glasgow by Fax.

  • Fax Number +44 (0) 141 301 7192



Stratification Factors

  • Centre

  • Choice of regimen

  • Gender

  • Disease site

  • T-stage

  • N-stage



Treatment arms

  • Arm A (Standard treatment) - 24 weeks of XELOX/OxMdG chemotherapy

  • Arm B (Experimental treatment) - 12 weeks of XELOX/OxMdG chemotherapy

  • Dose and administration of XELOX – 3 weekly cycle

  • - Oxaliplatin 130mg/m2 IV on day 1

  • - Capecitabine 1000mg/m2 PO twice daily for 14 days

  • Dose and administration of OxMdG – 2 weekly cycle

  • - Oxaliplatin 85mg/m2 IV on day 1 concurrently with

  • - I-folinic acid 175mg or folinic acid 350 mg followed by

  • - 5-FU 400mg/m2 IV bolus injection over 5 minutes followed by

  • - 5-FU 2400mg/m2 IV continuous infusion over 46 hours



Dose Guidelines for XELOX Regimen

  • At randomisation you will be asked for the patient’s starting dose of Capecitabine.

  • Patients with a creatinine clearance of 30-50mls/min must commence treatment with capecitabine at 75% of the full dose.

  • Patients > 70 years of age should be considered for treatment with capecitabine at 75% of the full dose but, in light of differences in standard practice between sites, this will be left to the discretion of the Investigator depending on the fitness of the individual patient. The decision not to dose-reduce must be documented in the patient notes.

  • At the Investigator’s discretion, patients can be commenced on a minimum starting dose of capecitabine of 800 mg/m2 if clinically indicated. The starting dose of capecitabine will be requested at baseline registration/randomisation.

  • Capecitabine dose banding tables are provided in appendix 3 of the protocol.
