    General information about the trial
    Main objective of the trial
    The study objective was to evaluate the efficacy and safety of Cx601 compared to placebo for the treatment of perianal fistulising CD over 24, 52 and 104 weeks. Dates of Database Locks were 27 Jul 2015 (Week 24); 29 Feb 2016 (Week 52) and 10 Feb 2017 (Week 104)
    Protection of trial subjects
    This trial was conducted in compliance with International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines for conducting, recording, and reporting trials, as well as for archiving essential documents. No trial procedures were performed on trial participants until written consent had been obtained from them. The informed consent form (ICF), protocol, and amendments for this trial were submitted to and approved by the Ethics committee. Routine monitoring was performed to verify that rights and well being of patients were protected. Also, any medication considered necessary for the patient’s safety and well-being was given at the discretion of the Investigator. Each patient was free to withdraw from the study at any time without giving a reason.
    Background therapy
    The following treatments were permitted: Antibiotics to treat the fistula during the study (including but not limited to ciprofloxacin and/or metronidazole) or antibiotics active against bacteria of the perianal region, provided no more than 4 weeks of continued treatment was administered. Azathioprine, 6-MP, or methotrexate, maintained at a stable dose, could be taken from IMP administration up to Week 52. No new treatment with azathioprine, 6-MP, or methotrexate was allowed up to Week 52. If there were complications derived from their use, a decrease in dose or suspension of the drug was allowed. Anti-TNFs maintained at stable doses. No new treatment with anti-TNF agents was allowed up to Week 52. Use of 5-ASA from time of treatment administration; thereafter only decreases in dose were allowed up to Week 52. Medications taken by the patient for other disease(s) were allowed. In event of doubt about concomitant treatments, the trial monitor was to be contacted. Patients were not allowed to receive investigational drugs or other local investigational treatments in the perianal region while participating in the study. Prior to Week 52, in case of a flare of the luminal disease, it was permitted to use an oral steroid course starting with prednisone/prednisolone at 40 mg, or equivalent, and tapering over 12 weeks, following usual clinical practice at the site. In this situation, the patient could continue in the study; but if the patient required a new immunosuppressant or new anti-TNF agent, or required higher doses of their existing immunosuppressant or anti-TNF medication compared to baseline, the patient was to be withdrawn and considered a treatment failure.
    Evidence for comparator
    The use of a placebo comparator group is in accordance with the EMA guideline, "Guideline on the development of new medicinal products for the treatment of Crohn’s Disease" CPMP/EWP/2284/99 Rev. 1, 2008 which states that “for an add-on indication, placebo is an acceptable comparator”.

    Recruitment
    Recruitment details
    A total of 212 patients were randomised in 8 countries (Austria, Belgium, France, Germany, Israel, Italy, the Netherlands and Spain) at 47 sites. Enrolment started on 06 July 2012. Last patient visit was on 10 Feb 2017 (week 104 follow-up).

    Pre-assignment
    Screening details
    A 5-week screening period was scheduled to determine a patient’s eligibility for inclusion in the study. All patients underwent the same pre-study preparatory surgery, performed at least 2 weeks before the administration day.

    Blinding implementation details
    IMP administration was not masked, because the cell suspension is clearly identifiable compared to the saline solution. One Investigator (surgeon) administered the IMP + another Investigator evaluated the fistula(s) in a blinded fashion. Surgeons who administered the IMP were not allowed to participate in any patient clinical assessment. Investigators responsible for patient assessments + patients remained blinded to the patients’ treatment allocation up to Week 52.

    Primary: Combined Remission of perianal fistulising CD - week 24

    Close Top of page
    End point title
    Combined Remission of perianal fistulising CD - week 24
    End point description
    The primary efficacy variable for this study was Combined Remission of perianal fistulising CD (defined as the clinical closure of all treated EOs that were draining at baseline despite gentle finger compression) and absence of collections >2 cm of the treated perianal fistula confirmed by evaluation of MRI images by a central laboratory that was blinded to the individual patient’s treatment and visit by Week 24. The main analysis was based on ITT approach where any patient with a missing value was imputed as a non-response. However, in case of missing clinical assessment by Week 24, the last observation carried forward (LOCF) from the latest earlier post-baseline visit (including an Early Termination Visit, if applicable) applied. In case of missing MRI data by Week 24, if there was an MRI at an Early Termination Visit prior to Week 24 then LOCF applied to this MRI.
    End point type
    Primary
    End point timeframe
    Fistula closure, used to assess the primary endpoints was clinically evaluated at Week 6, 12, 18, 24, 36, 52, 78, and 104 after initial administration of cells or placebo and evaluated via radiological assessment (MRI) at Week 24 and Week 52.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    31 Oct 2012
    Protocol amendment 1, version 2.0, included the following changes: - Addition of an extra 28-week follow-up period to allow assessment of long-term safety and efficacy; therefore, the overall study length was increased from 24 to 52 weeks. - Clarification of study procedures for fistula preparation, exclusion criteria, allowed rescue medication, placebo packaging and labelling, and cell product descriptions.
    17 May 2013
    Protocol amendment 2, version 3.0, included the following change: - Addition of immunological analysis of blood samples taken at Visit 0, Visit 2 and Visit 6 and Early Termination Visit (where appropriate) to allow assessment of alloreactivity in study patients. Update includes changes to visit procedures and update of informed consent process.
    08 Dec 2014
    Protocol amendment 5, version 6.0, included the following changes: - Addition of an extended follow-up period of up to 104 weeks to evaluate the long-term efficacy and clinical safety of Cx601 treatment, including additional assessments at Weeks 78 and 104. - Clarification of statistical analyses including definition of blinding procedures, primary and secondary efficacy and overall safety endpoints and definitions of datasets and analysis subsets. - Only SAEs will be reported and summarised in the 2nd follow-up period between Week 52 and Week 104.
    12 May 2016
    Protocol amendment 6, version 7.0, addressed the following changes: - After implementation of Amendment No. 5 it was noted that some points of the protocol might lead to potential misunderstandings and needed to be further clarified. Additionally, there were in the protocol some omissions that needed to be corrected for a correct understanding and compliance. - All analyses on other non-key secondary endpoints by Week 24, Week 52, and Week 104 will be only descriptive. - Urine analysis was removed from SAE laboratory parameters. - Only SAEs will be reported and summarised in the 2nd follow-up period between Week 52 and Week 104. The reference is added to some protocol sections which were inadvertently not updated when Amendment 5 was generated. - Percentages and difference between treatments will be expressed with their 95% CI calculated with a binomial exact method stratified asymptotic Wald’s CIs. Time to Clinical Remission and time to Response will be analysed with KM estimates. The estimate of the Hazard ratio of eASCs relative to placebo from stratified Cox regression, adjusting for the randomisation strata, will be presented together with 95% CI. - Immunological Analysis results will be reported independently of the Clinical Study Report.
