3 GENERAL STUDY INFORMATION
CHIEF INVESTIGATOR: Professor Mark Hull, Molecular Gastroenterology, University of Leeds FUNDER: Efficacy and Mechanism Evaluation programme (EME) Very competitive and rigorous process – Approx £1million SPONSOR: University of Leeds CO-ORDINATING CENTRE: Nottingham Clinical Trials Unit Anna Sandell Trial Manager Ellie Harrison Trial Administrator Statistics Data Entry Data Management

4 STUDY OUTLINE AND OBJECTIVES
OUTLINE: PHASE 3, RANDOMISED, DOUBLE-BLIND, PLACEBO-CONTROLLED 2X2 FACTORIAL TRIAL PRIMARY OBJECTIVE To determine whether the naturally-occurring omega -3 polyunsaturated fatty acid eicosapentaenoic acid (EPA) prevents colorectal adenomas, either alone or in combination with aspirin SECONDARY OBJECTIVE To assess the tolerability and safety of EPA in the free fatty acid form (EPA-FFA) alone, and in combination with aspirin, in elderly (60-75) years participants 1o endpoint – number of patients with a polyp(s) 2o endpoints – polyp number, ‘advanced’ lesions, location, AEs

5 PROTOCOL OUTLINE INCLUSION: 60-73 Yrs BCSP Patients Classified as High Risk at the first complete screening Colonoscopy within past 4 weeks nb high risk = 5 or more small adenomas or 3 or more adenomas with at least one being ≥10mm diameter

6 PROTOCOL OUTLINE EXCLUSION CRITERIA: main ones listed here (see protocol for extensive list) Need for more than one repeat colonoscopy or flexible sigmoidoscopy within a 3 month window Malignant change in an adenoma requiring colorectal cancer MDT management Regular (>3 doses/week) prescribed or OTC aspirin or prescribed or OTC non-aspirin NSAID use – not prepared to stop OTC use Aspirin intolerance, hypersensitivity including aspirin-sensitive asthma Active peptic ulcer disease within past 3 months or any previous peptic ulcer (not on PPI treatment) NB if taking PPI then they are eligible Fish or seafood allergy Current or planned regular(>3 doses/week) use of fish oil supplements - not prepared to stop OTC use

7 PROTOCOL OUTLINE cont. EXCLUSION CRITERIA: main ones listed here (see protocol for extensive list) Known clinical diagnosis or gene carrier of a hereditary CRC predisposition,(Familial Adenomatous Polyposis) or Hereditary Non Polyposis Colorectal Cancer Previous or newly diagnosed Inflammatory Bowel Disease or colorectal resection Known bleeding diathesis or concomitant warfarin therapy or any other anti- coagulant or anti-platelet therapy Severe liver impairment (anyone who is known to have or is likely to have a coagulopathy (INR>/=1.5) from liver impairment) Severe renal failure (creatinine clearance <10ml/min) Current Methotrexate use at a weekly dose of 15 mg or more Participating in another interventional clinical trial Failure to give Informed Consent

11 STUDY SCHEDULED VISITS & PROCEDURES
Colonoscopy – up to 4 weeks before V1

12 STUDY SCHEDULED VISITS & PROCEDURES
V1 (baseline total hr) - consent, randomisation, FFQ, blood and urine

13 CONSENT 3 OPTIONS: SSP or Research Nurse takes Informed Consent
SSP or Research Nurse takes Informed Consent but PI counter-signature is required PI only can take Informed Consent ALWAYS ENSURE YOU HAVE THE PARTICIPANT’S CONSENT PRIOR TO ANY STUDY RELATED PROCEDURE NB - ensure that you find out your Trust requirements prior to recruitment start - ensure that the PI has delegated the responsibility for Informed Consent to you and this is recorded on the delegation log prior to recruitment start

14 RANDOMISATION INSTRUCTIONS ARE AT THE FRONT OF EVERY CASE RECORD FORM
Web-based system Accessed from any computer with internet access https://ctu4.nottingham.ac.uk/0921/login.asp Easy to use Will provide Participant ID following confirmation of participant details (pt initials, gender, DOB) – use this ID for all study documentation Will generate prescription – print off, obtain prescriber’s signature, take to pharmacy Keep your username and password safe for log-in (audit trial) New members of staff need to request username and password – via Trial Manager If you cannot access the randomisation database – call Trial Manager

15 RANDOMISATION

16 randomisation

17 randomisation

18 prescription

19 PHARMACY & DISPENSING Prescription
generated from the web-based randomisation system and completed by the prescribing physician Note: EPA-FFA is a fish oil and allergy to fish oil is part of the exclusion criteria. It defines which container numbers should be dispensed for the participant. The container numbers specified will have been delivered to your hospital Give participant seAFOod bag to carry Trial Medication supplies participant will receive a total of 8 items (boxes/tubs) Inform participant to start the trial med next morning and always take with food Trial med to be stored at room temp at / below 25 deg C

25 STUDY SCHEDULED VISITS & PROCEDURES
V6 exit colonoscopy (week 50 or up to 62)– trial med return, AEs, bloods & urine, rectal biopsies (1.5hr)

26 STUDY SCHEDULED VISITS & PROCEDURES
V7 final visit (week 52 or up to 64) - adenoma details and FFQ ( 25 min) NB see protocol and CRF for time window allowances for each visit

27 BIOLOGICAL SAMPLES – why?
To understand how EPA and aspirin work, alone and in combination To identify a biomarker(s) that predicts whether EPA and/or aspirin works (towards personalised chemoprevention) To determine whether the patient genotype predicts efficacy of EPA and aspirin, alone or in combination

28 Liquid chromatography- tandem mass spectrometry

29 BIOLOGICAL SAMPLES - blood
Blood (3 times – start, middle, end) Blood handling Centrifuge (own lab or supplied equipment) Plasma (to measure lipid biomarkers) White blood cells (to obtain DNA) Red blood cells (to measure EPA levels) Lipids are labile so rapid cooling and freezing is preferred

30 BIOLOGICAL SAMPLES - URINE
Urine (3 times – start, middle, end) Measuring lipid metabolites including stable PGE2 metabolite

31 BIOLOGICAL SAMPLES – RECTAL BX
Rectal biopsies (exit colonoscopy only) Fixed adenoma tissue blocks (at end of trial) Rectal biopsies – measuring: 1) EPA incorporation 2) Mucosal lipid levels eg. PGE2, lipoxins, RvE1 Immunhistochemistry for: 1) COX-2 2) Cell receptors for eg. RvE1 (ChemR23)

32 BIOLOGICAL SAMPLES LAB MANUAL Instructions on processing and storage
30 mins from obtaining samples to freezer (allowing for site-specific factors) Unique id labels in Investigator Site File section 7 Collection of samples every 3-4 months by CitySprint courier Samples long term storage in Bradford lCT (Institute of Cancer Therapeutics) CONSUMABLES PROVIDED Blood tubes, aliquots, cryo rack, marker pen, Pathoseal bags, gloves 1st shipment to supply 10 participants

33 ADVERSE EVENT REPORTING
Always ask participant about Adverse Events at every phone call and clinic visit Record all on the AE log and update log at every phone call and clinic visit If AE fulfils SERIOUS criteria, complete SAE form immediately: Participant has died from the event Event is life-threatening if no immediate treatment given Event has prolonged an existing hospital admission or resulted in a new hospital admission Event has resulted in persistent or significant disability/incapacity Event has resulted in a congenital anomaly or a birth defect (following either parent taking trial medication) Medical or surgical intervention required to prevent one of the outcomes above Medically significant – does not fulfil any of the criteria above but in the opinion of PI, requires reporting

34 ADVERSE EVENT REPORTING
PI or delegate must complete SAE form immediately PI MUST SIGN and complete PI sections if PI unavailable for next 24 hrs, complete as much as possible and call Trial Manager Call Trial Manager to notify of an SAE Fax completed SAE form as soon as completed (within 24 hrs of notification of SAE) NB enquire specifically about dyspepsia, nausea, abdominal pain,halitosis, diarrhoea, bleeding episodes (including haematemesis/melaena) and diagnosis of stroke at each follow-up visit and telephone call For the purpose of this Trial pre-planned elective hospital submissions will not be classed as a SAE.

35 prohibited medications
PROHIBITED MEDS Warfarin or any other anti-coagulant or anti-platelet therapy (any dose), Regular (>3x per week on an ongoing basis) prescribed or OTC aspirin, Regular (>3x per week on an ongoing basis) prescribed or OTC non-steroidal anti- inflammatory drug (NSAID), Ongoing or planned use of fish oil supplements Methotrexate use at a weekly dose of 15 mg or more. NB: 1) Participants should be advised to avoid taking any aspirin-containing over-the-counter analgesia and to take an alternative (such as paracetamol) when pain relief is necessary. 2) “regular” = use on a continuing basis over a period of time in consecutive weeks

36 EMERGENCY UNBLINDING “For the majority of cases, unblinding will not be required because there is no antidote to the investigational treatments, and the medical care and usually the management of the patient would not be any different even if the treatment group assignment of the patient were known.” PROTOCOL EMERGENCY ONLY: Local hospital Pharmacy to unblind using unblinding web-based system  https://ctu4.nottingham.ac.uk/0921_unblind/login.asp If need arises for non-emergency unblinding then must be discussed with the CI

37 Withdrawal of participants
Participants can only be withdrawn from the trial completely if : Participant withdraws consent Participant lost to follow-up Participant had more than 1 repeat colorectal endoscopy Investigator’s opinion due to an Adverse Event Participants who stop trial medication will still be followed- up until end of trial Participants who are unblinded to their treatment allocation will stop the trial medication but will still be followed up until the end of the trial AN END OF TRIAL CRF SHOULD ALWAYS BE COMPLETED

38 Trial medication side effects ?
Main side effects are: diarrhoea, nausea, dyspepsia, abdominal pain 1) Always check participant taking trial medication with food 2) Trial med can be reduced if AEs causing participants distress Capsules can be reduced to 1 capsule BD (increase after 1 -2 weeks) Aspirin can only be stopped not modified

39 Flow chart of EPA/placebo capsule reduction
Adverse Events? Has participant had any of the following persistent symptoms which has lead to consideration of stopping IMP? nausea abdo pain/dyspepsia diarrhoea What number of capsules is participant taking? Are capsules and tablets taken with food? TWO twice a day NO YES NO YES Give advice about taking IMP with meals Continue to take TWO capsules twice a day ONE twice a day YES What number of capsules is participant taking? Increase back to TWO twice a day with food (see note below) TWO twice a day ONE twice a day Reduce to ONE twice a day until next visit/call Consider stopping capsules but continue tablets and call Trial Manager No capsules Telephone check up within 2 weeks Consider stopping tablets and call Trial Manager Note:- participant should only be encouraged to increase back to TWO capsules twice a day on ONE occasion during the trial. If a participant has increased the number of capsules with return of symptoms then he/she should remain on ONE capsule twice a day

40 Investigator site file

41 Study management CENTRE expectations
Each BCSP Centre has a target of recruiting a total of 60 participants over 2 yrs can be divided between the separate sites within the BCSP If poor recruitment within 6 months - ? Close site and open a new site All personnel who will be working on seAFOod need to have a GCP certificate and have been trained either at this SIV or by PI/SSP All patients who are classified as “high-risk” must be entered onto the screening log regardless of whether they are eligible or not. Crucial for reports and trial management that this data is captured Screening logs to be faxed through to Ellie every 2 weeks (wednesdays) reminders will be sent All personnel need to be recorded on the delegation log with their duties recorded A copy of this must be sent to CTU and hospital pharmacy every time there is an alteration

42 Study management expectations
All CRFs to be posted to the Clinical Trials Unit within 1 week of completion All data captured within the CRF must also be noted either on the BCSP database or within the patient’s medical records Participant’s medical records must have an entry to say that consent has been given for entry to seAFOod trial Any invoices for participant travel expenses (up to £10 – must have receipts) or admin costs be submitted to myself CTU with receipts
