4 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 Randomise STANDARD 24 weeks XELOX/ OxMdG Chemotherapy [4750 patients] EXPERIMENTAL 12 weeks

5 Objectives & Endpoints
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

6 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

7 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.

8 Upfront Prior to treatment

9 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)

10 Patient Randomisation
All patients must be randomised onto the study prior to commencement of any treatment. Check that patient has given written informed consent. Check that patient fulfils eligibility criteria. Check that randomisation is taking place within 10 weeks of surgery. Complete Registration/Randomisation Form. PHONE or FAX randomisation details to the randomisation team at the CTU Glasgow Each patient registered will be allocated a unique study identifier. Contact GP (See GP Letter in the Protocol). RANDOMISATION SERVICE CTU Glasgow randomisation service Tel: Fax: * 08:30 –17:00 Mon–Thurs, Friday, except public holidays *Faxes received outside of office hours will be processed the next working day

11 Stratification Factors
Centre Choice of regimen Gender Disease site T-stage N-stage

12 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

13 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.

Visualisation of entire colon should be performed as per local practice (please note if this has not been carried out pre surgery it must be performed within 12 months post surgery). Any relapse or incidence of new colorectal and primary tumours must be confirmed by imaging and/or histology/cytology as appropriate and reported on the next FU Form If the patient has completed treatment as per protocol or the treatment has been withdrawn due to recurrence or some other clinical decision, the patient should be followed-up as per protocol.

23 Additional studies Centres will be asked if they are willing to participate in Quality of Life collection Quality of Life, economic and detailed toxicity data are required for approximately 700 patients Quality of Life data The QLQ-C30/CR29 questionnaires should be completed by patient prior to randomisation, on day 1 of chemotherapy of each cycle of treatment and at follow up visits until year one. Economic data The EQ-5D questionnaire to be completed at the same frequency as QLQ questionnaires and at all follow up visits until study completion Detailed toxicity data Toxicity will be graded using the NCI-CTCAE Version 3.0 GOG Ntx 4 (neurotoxicity) questionnaire will be completed by patients at the same frequency as the QLQ Forms

24 End of Treatment For all patients:
At the end of treatment, the decision to end treatment and date of last treatment should be recorded on the last Treatment CRF (Future Study Treatment section); For patients where the treatment has been withdrawn (full treatment not completed): The reason for this should be recorded on the last Treatment CRF (Reasons for Early Treatment Withdrawal section); If the treatment has been withdrawn due to recurrence, note the recurrence details on the 1st follow-up form;

25 Consent Withdrawal This is when the patient specifically asks to withdraw their consent at any point in the study; If this occurs: Complete the consent withdrawal form and keep a copy at site and a copy for the patient; Send the consent withdrawal notification form to your coordinating centre; No further follow-up should be collected on the patient from that point onwards.

26 Pharmacovigilance Definition of an Adverse Event
An adverse event (AE) is defined as any untoward medical occurrence that is not necessarily related to protocol treatment All AEs must be followed; - until resolution, - or for at least 30 days after discontinuation of study medication, - or until toxicity has resolved to baseline, - or < Grade 1, - or until toxicity is considered to be irreversible All AE and toxicities must be graded according to the NCI-CTCAE Version 3.0 Abnormal laboratory test should be recorded as an AE in the CRF AE that are not defined as AR do not require to be recorded in the CRF

27 Adverse Reactions Definition of an Adverse Reaction
An adverse reactions (AR) is any untoward and unintended responses to an investigational medicinal product related to any dose administered AR information will only be collected on CRFs for a limited number of patients. Once this information has been collected sites will be advised that AR information is no longer required An exacerbation of a pre-existing AR after commencement of trial should be recorded on CRFs

28 Definition of a SERIOUS ADVERSE EVENT
A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that is not necessarily related to protocol treatment that: Results in death Is Life-threatening Requires hospitalisation or prolongation of existing hospitalisation Results in persistent or significant disability or incapacity Consists of a congenital anomaly or birth defect Is considered medically significant by the Investigator

29 Definition of a SERIOUS ADVERSE EVENT- 2
Life threatening: The patient is at immediate risk of death from the event as it occurred. It does not include an event that, had it occurred in a more serious form, might have caused death. Requires in-patient hospitalisation: Is a hospital admission required for treatment of an adverse event even when the adverse event is not related to the protocol treatment.

30 Reporting SAEs Serious Adverse Events (SAEs) must be reported immediately (within 24 hours of knowledge of the event) Sites must have a system for SAE reporting in the absence of the Research Nurse or Principal Investigator. SAEs are reported using the CTU SAE report Form Sites must complete the SAE report Form and fax the report to Pharmacovigilance at the Glasgow CTU fax number The CTU will create a SAE reference number and will send an acknowledgement fax to confirm receipt The CTU will request additional information if the event is unexpected CTU will raise queries for any inconsistent or missing information SAEs must be reported locally by the PI at each site in accordance with the local practice at their site (i.e. Ethics Committee, R&D Office) SAEs are required to be reported for up to 30 days after discontinuation of study medication Any SAE that occurs after 30 days post treatment is also required to be reported if the PI thinks that the SAE is related to the protocol treatment, or is medically important LD- suggest Serious Adverse Event (SAE) for 1st mention Staff ‘Contact’ and……………….. Capital for SAE ‘F’’orm

31 SAE Report Form completion – General Tips
Always fax SAE report forms and SAE queries. Do not post original SAE reports. Keep and file original SAE reports and original copies of SAE queries with other patient CRFs. SAE Reports are faxed to allow for the tight time frame for identifying and reporting SUSARs. Always include a fax cover sheet when submitting an SAE report or queries. The cover sheet should identify who is submitting the report/queries and their contact details. Do not use abbreviations for completing any part of the SAE report or SAE queries. Do not fax lab reports or test results with the SAE report form Document only medically significant and pertinent lab findings in the SAE summary section.

32 SAE Report Form completion – weak areas - 1
Section 1 – Study/Patient Details Report date should be the date of report completion, which is close to the report signature date and within a day of the date the report is faxed. Post dating SAE reports to attempt to disguise late reporting is not acceptable. Section 2 – Protocol Drug Treatments Ensure the frequency is correctly recorded (for capecitabine use the phrase as per protocol) and the correct cumulative doses are provided. Section 3.4 – Adverse events Ensure that the adverse event section is completed and the adverse events listed are consistent with those recorded in the SAE summary. Often additional AEs are mentioned in the SAE summary which do not appear in the adverse event section. Section 3.4 – Adverse Events – when submitting an initial report the adverse event section is a mandatory field. Each adverse event that comprises the SAE must be listed using the appropriate CTCAE short name. Please do not enter adverse events that do not appear on CTCAE Version 3. The relationship of each adverse event to each trial drug must be reported using the appropriate code: 0=not applicable, 1=related, 2=possible, 3=probable 4=definite Do not record the relationship to protocol treatment using a tick. Please ensure the correct code is entered into the appropriate column for each trial drug.

33 SAE Report Form completion – weak areas - 2
Section 3.6 – Summary of SAE Use clear and legible writing without abbreviations. Describe the SAE with the correct chronology consistent with the adverse events listed in the adverse event section. Section 4 – Concomitant Medication List treatment in use before or at the time the SAE occurred, not that used for treatment of the SAE. These medications should be recorded in the summary of the SAE section.

34 SAE Report Form completion – Mandatory Information at Initial Notification
Trial drugs must be listed on the SAE report in Section 2: Protocol Drug Treatments. Complete as much information as possible. It is important that dates of administration are reported. The adverse event section and particularly the relationship to protocol treatment must be completed at initial notification of the SAE. The relationship may change on a follow up report when there is more information or if the PI was unavailable to review the causality initially. SAE report forms must be signed by the PI / designee as agreed on the staff contact and responsibility sheets. If the PI / designee are unavailable to sign the report form please fax it unsigned and again as soon as it is signed. If you are unsure if to report an event as an SAE or need any guidance on completing the SAE report form please contact Lindsey Connery Tel: or at Pharmacovigilance at the Cancer Research UK, Clinical Trials Unit, Glasgow.

35 Procedure for Identifying and Reporting Unexpected and Related Events
A checklist of the events expected to occur in patients receiving the protocol treatment will be used to identify SUSARs SAEs that meet the criteria for SUSARs will be reported to the MHRA, Main REC and Sponsor where in the opinion of the Chief Investigator the event was: Related – that is, resulted from administration of any of the research procedures And Unexpected – that is the type of event is not listed in the Investigator Brochure, or Summary of Product Characteristics (SmPC) as an expected occurrence Reports of related and unexpected SAEs will be submitted within 7 days for fatal/life threatening events and 15 days for all other events. We will require sites assistance with gathering information for SUSARs reports

36 Non-Investigational Medicinal Products (NIMPs)
NIMPs are any drug, mentioned in the protocol that is administered to patients in addition to the trial drug treatment. This includes rescue medication such as analgesics or antiemetics and medications for symptom relief If a SAE is considered related to a NIMP then it requires to be reported and the NIMP (which is implicated) requires to be identified. The NIMP for this study is glucose If a SAE is considered to be an interaction between a NIMP and the IMP (the treatment drug) then it also requires to be reported The Chief Investigator is responsible for deciding if a SAR that is related to a NIMP requires expedited reporting

37 Annual Safety Reports A report on the safety of trial participants from all trial sites will be prepared by the CTU Glasgow and submitted to the MHRA, Main REC, Sponsor & Trial Investigators

38 Dose modifications for toxicity
If grade 1 toxicity occurs treatment should continue Dose modifications for diarrhoea, haematological and neurosensory toxicity can be found in the protocol For all other toxicities > grade 3, treatment should be withheld until recovery to < grade 1 then restarted if medically appropriate If patients take three weeks or longer to recover from chemotherapy-related toxicity they will receive no further treatment In the situation where oxaliplatin is discontinued due to toxicity, adjuvant treatment can continue with 5-FU alone Crossover from capecitabine to 5-FU and vice versa is allowed for reasons of toxicity Once the dose has been reduced it must not be escalated LD- suggest ‘should’ rather than ‘will’ for 1st sentence What about grade 2?

39 Study Drug All IMPs for use in this trial should be taken from existing pharmacy shelf stock. There is no provision for funding, reimbursement or discounted stock IMPs should be stored under the correct conditions as per the SmPC All products used in this study are licensed medications and will not be labelled specifically for the study IMP accountability logs will be provided for use, these must be maintained for the duration of the study and must be kept in the study pharmacy file Patients should be asked to return any unused capecitabine tablets at each study visit

40 Translational research
We are planning to submit a grant application to CR-UK for sample collection and storage for blood, urine and tissue samples Full information will follow at a later stage Currently patients are asked to consent to this section of the study. Those patients who consent, at this time, are only consenting to us approaching them at a later date with full details of the translational research.

41 Monitoring Plan All patients monitored for: Consent
