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   43974   clinical trials with a EudraCT protocol, of which   7312   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 ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The aim of this study is to answer the question “Is it possible (feasible) to undertake a trial within a cohort to investigate the effect of OK432, administered directly into the chest in people with mesothelioma, and is it acceptable to patients and relatives?”

    This research will determine whether a full-scale version of the trial is possible. If it is, the results of this research will inform the design of the subsequent full-scale trial.

    The long-term goal is to determine whether OK432 is an effective treatment for mesothelioma, and whether the trial within a cohort design is appropriate for mesothelioma trials.
    E.2.2Secondary objectives of the trial
    The secondary objective of this study is to gather preliminary (exploratory) information on the clinical effect of OK432 administered into the lung lining in people with mesothelioma. This information will be used to decide what the primary outcome measure of the subsequent full-scale trial should be. The results for the chosen outcome measure from this research will be used to calculate the sample size needed for the subsequent trial.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    To participate in TILT patients must meet all of the following inclusion criteria:
    • Histological or cytological diagnosis of mesothelioma
    • Enrolled in ASSESS-meso and has given consent to be considered for and be randomly selected for future trials
    • Indwelling pleural catheter (IPC) in situ that has drained more than 50ml of fluid on previous 3 drainages OR willing to have an IPC and has a pleural effusion suitable for IPC insertion
    • No chemotherapy in preceding 4 weeks and none planned in subsequent 4 weeks
    • Performance status ≤2, or PS 3 and felt clinically suitable for trial
    • Predicted survival ≥12 weeks from enrolment
    • Able to give written informed consent & meet trial requirements
    E.4Principal exclusion criteria
    To be eligible for TILT, participants must have none of the following exclusion criteria:
    • No indwelling pleural catheter (IPC) in situ, and has contra-indication to IPC insertion
    • Clinico-radiological diagnosis of mesothelioma
    • Trapped lung with <50% pleural apposition on x-ray
    • Moderately heavy or heavily loculated pleural effusion
    • Known immunodeficiency or immuno-suppressive medication
    • Intercurrent infection (pleural or elsewhere) or clinical signs of sepsis
    • Known sensitivity or allergy to OK432 or penicillin
    • Previous treatment with immunotherapy
    • Currently enrolled in any other interventional clinical trial
    • Brain metastases or CNS involvement of mesothelioma
    • Pregnancy or lactation, current or planned during the study period
    • Age <18
    • Any other factor that, in the opinion of the Chief Investigator, would mean participation in the study would be contraindicated
    E.5 End points
    E.5.1Primary end point(s)
    This assessment will be based on:
    • Screening, eligibility and recruitment rates to TILT
    • Feasibility of identifying 45 eligible participants in a 12 month period
    • Acceptance rates for intra-pleural OK-432 following random selection
    • Collection of data on participants who declined to receive OK-432 when offered it
    • Collection of data on participants within ASSESS-meso who declined to be considered for future trials
    • Attrition rates and data completeness rates
    • Acceptability of trial processes and design to participants and their relatives, assessed qualitatively.
    E.5.1.1Timepoint(s) of evaluation of this end point
    This will be evaluated at the end of trial - i.e. 12 weeks after the final participant has enrolled.
    E.5.2Secondary end point(s)
    Secondary outcome measures will collect exploratory data on the clinical efficacy of OK-432. This data will be used to decide the primary outcome for the subsequent full-scale trial, and to estimate the variance of the chosen outcome for a sample-size calculation. Potential outcomes include:

    • Tumour response, based on CT appearances
    • Overall survival (OS), defined as time between date of diagnosis with MPM to date of death, censored 12 weeks after the final trial visit of the final participant
    • Progression-free survival rates
    • Patient-reported chest pain and breathlessness, measured on visual analogue scales
    • Patient-reported quality of life, measured using the EQ-5D-5L health questionnaire
    • Pleurodesis rates, defined as pleural fluid drainage of less than 50ml on 3 consecutive occasions, with <25% opacification on CXR or <250ml pleural fluid on thoracic ultrasound scanning (TUS)
    • Time to pleurodesis, calculated from baseline assessment to date of pleurodesis
    • Biomarker response assessed using serial serum and pleural mesothelin levels.
    • Pleural fluid cytokine response, including VEG-F and TNF-α
    E.5.2.1Timepoint(s) of evaluation of this end point
    Tumour response will be assessed at baseline and 12 weeks
    Overall survival will be assessed at the end of trial (last visit of last participant)
    Progression free survival rates will be assessed at 12 weeks
    Patient reported outcomes and QoL will be assessed at baseline, week 2, week 5 and week 12
    Daily VAS scores will be collected for 21 days between week 2 and week 5
    Pleurodesis rates will be assessed at week 5 and week 12
    Biomarkers and pleural fluid cytokines will be measured at week 0, week 2, week 5 and week 12.
