Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    The principal research objective for this study is to demonstrate the acceptability and feasibility of recruiting to a randomised chemoprevention study of standard (300mg) or low dose (100mg) aspirin vs. placebo and/or Vitamin D3 vs. placebo in patients enrolled on an active surveillance programme for prostate cancer.
    Protection of trial subjects
    Helicobacter pylori (H. pylori) has been shown to be a causative factor in GI bleeding, so all participants were tested for this at randomisation as a precaution. Patients were allowed to start their study medication, including aspirin/placebo aspirin, prior to obtaining the result of this test, as patients are not normally tested for this infection before commencing aspirin therapy and the maximum aspirin dose in this study is very low. Patients who tested positive were prescribed a course of proton pump inhibitors (PPIs) and antibiotics if they wished to continue on the study. GPs were informed. Once treated, there was no requirement to retest for this infection (as per NICE guidelines). As a precaution, patients are advised to stop the aspirin/placebo tablets 7 days prior to prostate biopsy, or any other planned surgery. Patients will be reminded about this in the clinic, and this information is also included in the PIS and Diary Cards. There is no need to stop the Vitamin D3/placebo IMP prior to surgery. Serum calcium levels will be checked at baseline and 6 monthly intervals. Administration of the Vitamin D3/placebo may be delayed if a participant experiences symptoms of hypercalcaemia. Dyspepsia has been shown to be a risk factor for NSAID GI bleeding Therefore, should new dyspeptic symptoms arise, or a gastrointestinal bleed occur (melaena, haematemesis, decreased haemoglobin) during the course of the study, then treatment with aspirin/aspirin placebo should cease immediately and permanently, and the patient will withdraw from the study. In addition, administration of IMP will be discontinued if the patient develops a condition requiring treatment with a prohibited concomitant therapy, a condition which, in the judgement of the investigator, adversely affects the participant's safety, compliance or ability to complete evaluations and/or If the investigator concludes that this course of action is in the participant's best interests.
    Background therapy
    N/A
    Evidence for comparator
    Aspirin is a common Non-Steroidal Anti-Inflammatory Drugs (NSAID) used for analgesia & as an antipyretic. These drugs inhibit the enzyme cyclo-oxygenase which is involved in the metabolism of prostaglandins & thromboxanes, which in turn are involved in many physiological pathways including inflammation & platelet function. Aspirin is a reversible inhibitor of cyclo-oxygenase 1 (COX-1). Data suggests that in contrast to other NSAIDS, it may have anti-carcinogenic properties for many cancer types, including prostate cancer. Kashiwaqi demonstrated that aspirin down-regulated the androgen receptor which drives prostate cancer metabolism, & down-regulates prostate specific antigen (PSA) levels within prostate cancer cells. Kashiwaqi demonstrated that aspirin up-regulates prostaglandin receptor subtype EP3, which again influences androgen receptor expression & cell proliferation, thought to be important in prostate carcinogenesis. Epidemiological studies have also provided data on the benefit of aspirin on prostate cancer incidence & progression. Vitamin D is a fat-soluble secosteroid responsible for intestinal absorption of calcium & phosphate. Data suggest Vitamin D may influence the incidence of cancer. The mechanism for action may be due to calcitriol’s influence on cellular proliferation, differentiation and apoptosis. The Vitamin D receptor is known to be highly expressed in epithelial cells at risk of carcinogenesis, such as prostate. Mondul identified that genetic variants related to lower 25(OH)D levels were associated with a decreased risk of aggressive prostate cancer. it has been suggested that Vitamin D deficiency over time may contribute to the progression of insignificant prostate cancer to clinically significant disease. Marshall & colleagues evaluated Vitamin D supplementation in men with low to intermediate risk prostate cancer, reporting that those receiving Vitamin D had a lower number of positive cancer cores on repeat biopsy at 1 year.

    Recruitment
    Recruitment details
    Recruitment will take place in prostate clinics at 6 participating centres, based within the UK only. The aim will be to recruit 102 participants over a 12 month period, starting Dec 2016. Recruitment tools = study invitation letter, trial poster & a trial website.

    Pre-assignment
    Screening details
    Potentially eligible patient given a Patient Info Sheet & added to local Pre-screening log, (initials & DOB only). Informed consent taken from interested patients & pre-randomisation Eligibility Assessment conducted. Participants must have a corrected serum calcium level ≤ 2.65mmol/l & a negative H Pylori test result prior to starting IMP.

    Randomisation will be by bespoke web-based application. All relevant research staff will be trained in its use. Eligible participants will be randomised in a 6-arm 1:1:1:1:1:1 design. Randomised blocks will be used to maintain balance amongst these 6 arms, & the aspirin placebo groups will be block randomised to either small or large aspirin placebo tablets. The allocated unique study number will correspond to a particular arm of the trial, & used to label & identify all trial samples.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: There was no formal statistical analysis of the primary endpoint. There was an aim to recruit 102 patients based on an estimated 30% recruitment rate. The number of patients actually recruited was 104 and so the primary endpoint was met.

    Disease progression by MRI
    End point description
    Disease progression is defined as increase in lesion volume of >33% or an upgrading of MRI stage of disease to T3 or above. In the case where no lesion was identified by MRI screening, disease progression is defined as the development of a lesion of 0.2cc or greater and being assigned a PIRADS score of 4 or 5 Disease regression is defined as a decrease in lesion volume of > 33% or the absence of a lesion at 12 months where one was detected at baseline

    Timeframe for reporting adverse events
    AEs should be reported from the date of first randomisation until the end of trial, defined as the date of the Last Patient Last Visit (LPLV) & 30 days.
    Adverse event reporting additional description
    3 monthly fup. Adverse event CRF completed & patient diary checked by the research nurse at each appointment. Patient stops treatment early or does not attend their ‘End of Study’ appointment? The LCO is responsible for checking their AE status via a telephone at least 30 days after the date the participant has stated they stopped their IMP.
