Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42758   clinical trials with a EudraCT protocol, of which   7042   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To establish the comparative effectiveness of a prolonged course of antibiotics (clarithromycin) or endoscopic sinus surgery (ESS) in adult patients with CRS in terms of symptomatic improvement and costs to the NHS and patients, compared with standard medical care and each other at six months.
    E.2.2Secondary objectives of the trial
    • Measure clinical effectiveness using subjective self-reporting ratings and objective clinical measures
    • Compare the clinical effectiveness according to phenotype (CRSwNPs/CRSsNPs)
    • Record the incidence and details of adverse events in all treatment arms related to the trial medication or surgery intervention
    • Establish the cost effectiveness and cost utility over the 6 month trial duration
    • Embed a mixed methods evaluation into the main trial to identify factors and processes necessary for implementation of trial findings

    Internal recruitment pilot phase objectives
    • To randomise 72 participants at 6 pilot sites within 6 months. Recruitment will be deemed successful if ≥75% of expected, i.e. 54 patients are recruited
    • Undertake a MACRO Conversation Study (using qualitative methods) during the pilot phase to identify recruitment challenges and optimize recruitment during the main trial phase.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Adults aged 18 and over with a diagnosis of CRS according to European guidelines:
    *A minimum of 12 weeks history of inflammation of the nose and paranasal sinuses characterised by two or more symptoms, one of which should be either nasal blockage/obstruction/ congestion or nasal discharge (anterior/posterior nasal drip):
    - ± facial pain/pressure
    - ± reduction or loss of smell
    • Nasal endoscopy (within last 3 months) to determine CRS diagnosis and phenotype (CRSwNPs or CRSsNPs)
    • Non-contrast CT scan (within last 12 months) to determine Lund-Mackay score and confirm suitability for ESS
    • Moderate/severe symptoms; SNOT-22 score ≥ 20 within last 3 months
    • Symptom control not achieved following previous AMT, as deemed by the local Principal Investigator (PI) or Co-Investigator (Co-I), and therefore considered eligible for ESS
    • An understanding of the English language sufficient to understand written and verbal information about the trial, its consent process and the study questionnaires
    E.4Principal exclusion criteria
    • Lund-Mackay non-contrast CT scan score < 4
    • Macrolide antibiotic treatment for > 3 continuous weeks’ duration within the last 12 months
    • ESS in previous 6 months or visible, open sinus cavities from previous surgery
    • Maintenance oral steroids or biologics
    • Rare/complex sinus conditions:
    *CRS secondary to systemic disease - cystic fibrosis, granulomatous diseases
    *Suspected malignancy
    • Allergic fungal rhinosinusitis confirmed or suspected on CT imaging (expansion and mixed density opacification) necessitating immediate surgery
    • Severe asthma (high doses of inhaled steroids i.e. >1.5mg per day)
    • Females who are pregnant or breastfeeding, females of reproductive potential not prepared to use a reliable means of contraception (e.g. hormonal contraceptive patch, intrauterine device, physical barrier or abstinence, if preferred and usual lifestyle of the patient) at trial entry or those females wanting to start a family during the initial 3 months of the trial
    • Known immunodeficiency states including HIV and selective and multiple antibody deficiency states
    • Severe septal deviation preventing endoscopic examination
    • Contraindications to surgery (significant medical co-morbidity)
    • Any absolute contraindications to clarithromycin (risk factors to be assessed at screening include history of ischaemic heart disease, prolonged Q-T interval on ECG, diabetes and age over 65 or any medications known to interact with clarithromycin unless these can be discontinued during the 3 months of clarithromycin/placebo treatment)
    • Known allergies to the IMP and excipients of IMP and placebo
    • Inability to give consent (significant cognitive impairment or language issues), or to understand and comply with trial instructions
    • Participation in another Randomized Clinical Trial in the past 4 months
