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   43851   clinical trials with a EudraCT protocol, of which   7283   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 ).

    Recruitment
    Recruitment details
    This was a multicenter, open-label extension study of the safety and efficacy of ataluren in male and female participants with nmCF aged ≥6 years who successfully completed Study PTC124-GD-009-CF (NCT00803205 [Study 009]).

    Pre-assignment
    Screening details
    Participants began the open-label extension study immediately after completing end-of-study visit (Week 48) in Study 009 to avoid interruption in treatment. Most assessments performed at Study 009’s final visit were used as Baseline assessments in Study PTC124-GD-009e-CF (009e). Investigators and participants remained blinded to Study 009 dosing.

    Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) [1]
    End point description
    A TEAE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship that occurred or worsened in the period extending from the first dose of study drug to 6 weeks after the last dose of study drug. A serious adverse event (SAE) was an adverse event (AE) resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. AE severity was graded as follows: Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: life-threatening; Grade 5: fatal. A TEAE was considered related if in the opinion of the Investigator it was possibly or probably caused by the study drug. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the Adverse Events module.

    Spirometry was used to assess pulmonary function by measuring the percent-predicted, which was determined on the basis of the height value obtained at the same study visit, for FEV1 (the amount of air that can be exhaled in 1 second). Spirometry was validated by using current guidelines of the American Thoracic Society (ATS) and European Respiratory Society (ERS). Baseline was defined as Week 1 or the most recent value of percent-predicted FEV1 prior to the first dose of open-label treatment in Study 009e.

    Number of Participants With Pulmonary Exacerbations as Defined by Modified Fuch's Criteria
    End point description
    A Respiratory Event Form (REF), which collected data on various signs, symptoms, and effects for each event, was completed by the Investigator when informed by the participant of a respiratory event. Pulmonary exacerbations were assessed by using the modified Fuchs' criteria, which defines an exacerbation as a respiratory event requiring treatment with parenteral antibiotics for any 4 of the following 12 symptoms with or without intravenous (IV) antibiotics: change in sputum; new or increased hemoptysis; increased cough; increased dyspnea; fatigue; temperature >38°C; anorexia; sinus pain; change in sinus discharge; change in physical examination of the chest; or decrease in pulmonary function by 10% or more from a previously recorded value; or radiographic changes indicative of pulmonary function.

    Change From Baseline for the Respiratory Domain Score of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at Weeks 48 and 96
    End point description
    The CFQ-R consists of 44 items, including generic scales (physical and role functioning, vitality, health perceptions, emotional and social functioning), and cystic fibrosis (CF)-specific scales (respiratory and digestive symptoms, body image, eating disturbances, and treatment burden). Scores range from 1 to 4; higher scores indicate better quality of life (QOL). For some questions, the scale was reversed, so that 1 indicated better QOL. Domain scores were linearly transformed to a 0-100 scale, so that higher scores indicate better QOL. Domain scores were calculated as follows: 100*(sum of responses-minimum possible sum)/(maximum possible sum-minimum possible sum). Minimum possible sum=number of questions*1; maximum possible=the number of questions*4. Baseline=Week 1. A negative change from Baseline indicates that health has worsened. Participants may have switched age groups during the study. 'n' signifies participants evaluable for specified categories. 99999=Data Not Available

    Change From Baseline in the Concentration of Sweat Chloride at Week 48
    End point description
    Sweat was collected, from each arm, by using pilocarpine iontophoresis. The chloride concentration in the sweat was quantified for each arm by using standard laboratory methods. Tests were considered valid if the sweat collection time was ≤35 minutes; tests with longer collection times were also considered valid if extra time was needed to obtain sufficient volume (≥15 uL) for analysis. For analysis purposes, the average of the values from each arm were computed. If the assessment was valid and/or available in only 1 arm, this value was used as if it were the average of both arms. The method used was consistent with the guidelines of the Cystic Fibrosis Foundation Therapeutics - Therapeutic Development Network. Baseline was the most recent value of sweat chloride prior to treatment in Study 009e. A positive change from Baseline indicates that sweat chloride concentration increased.

    Spirometry was used to assess pulmonary function by measuring the percent-predicted (determined with the height value obtained at the same study visit) for FEV1 (the amount of air exhaled in 1 second). Spirometry was validated with current guidelines of the ATS and ERS. Baseline was defined as Week 1 or the most recent value of percent-predicted FEV1 prior to the first dose of open-label treatment in Study 009e. Analyses of the Study 009/009e 96-Week Completer Population, which included participants who completed 48 weeks of treatment with ataluren or placebo in Study 009 and ≥48 weeks of treatment with ataluren in Study 009e, complemented analyses of the Study 009e As-Treated population. 'n' signifies participants evaluable for the specified week.

    End point description
    Spirometry was used to assess pulmonary function by measuring the percent-predicted (determined with the height value obtained at the same study visit) for FEV1 (the amount of air exhaled in 1 second). Spirometry was validated with current guidelines of the ATS and ERS. The percentage of change in percent-predicted of FEV1 was calculated as follows: ((percent-predicted FEV1-Baseline percent-predicted FEV1)/Baseline percent-predicted FEV1)*100. Baseline was defined as Week 1 or the most recent value of percent-predicted FEV1 prior to the first dose of open-label treatment in Study 009e. A positive change from Baseline indicates that FEV1 improved. Analyses of the Study 009/009e 96-Week Completer Population, which included participants who completed 48 weeks of treatment with ataluren or placebo in Study 009 and ≥48 weeks of treatment with ataluren in Study 009e, complemented analyses of the Study 009e As-Treated population.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    07 Feb 2011
    This amendment introduced the following changes: * Increased the length of the study from 48 weeks to 96 weeks and added additional clinic visits and assessments as a result of the longer study duration. * Corrected the definition for a ≥Grade 2 elevation in serum creatinine to correctly reflect the Common Terminology Criteria for Adverse Events definition of a Grade 2 serum creatinine elevation (from ≥1.5*ULN for age to >1.5*ULN for age). * Revised the text to allow more flexibility in the transition from Study 009 to Study 009e. * Provided more detail regarding the collection of pharmacokinetic samples.
    06 Mar 2013
    This amendment introduced the following changes: * Removed TEPD, sweat chloride, and CT scans as secondary study endpoints. * Added a summary of TEPD, sweat chloride, and CT scan results from Study 009 to provide the rationale for removal of these parameters as secondary study endpoints. * Revised information on renal abnormalities to reflect the final data from Study 009. * Clarified that study drug must be interrupted if intravenous aminoglycosides or other nephrotoxic antibiotics (for example, vancomycin) were administered and clarified that appropriate laboratory procedures for monitoring therapy for CF pulmonary exacerbations or other CF complications pertained to the administration of non-nephrotoxic systemic antibiotics. * Clarified the assessments that should be performed for participants who prematurely discontinued from the study (that is, before Week 96) and whose last dose of ataluren was taken >4 weeks before discontinuation. * Changed the name of the vendor name for safety reporting from Kendle International to INC Research. * Clarified that nephrolithiasis should be reported as an AE of special interest and that laboratory abnormalities as a result of analysis by the central laboratory did not need to be reported to the INC Research Safety and Pharmacovigilance Unit. * Added an acceptable window (±30 days) for the collection of long-term safety data. * Revised the total amount of blood that would be drawn over the 96-week study from 181.5 mL to 202.5 mL to correct an administrative error.
