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   43857   clinical trials with a EudraCT protocol, of which   7284   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 primary objective of this study was to demonstrate the efficacy as measured by the changes from baseline to the end of Week 16 in the Western Ontario and McMaster University Osteoarthritis Index [WOMAC] pain and physical function subscale scores, safety, and tolerability of fulranumab subcutaneous (SC) injections as monotherapy compared with placebo SC injections in subjects who had signs and symptoms of osteoarthritis (OA) of the hip or knee that were not adequately controlled by their current pain therapy and who were planning a joint replacement surgery.
    Protection of trial subjects
    Safety was evaluated throughout the study and included monitoring of adverse event (AE), clinical laboratory testing, vital sign collection (including orthostatic testing), neurologic evaluation (abbreviated neurologic examination including an assessment of pupillary light reflex and signs consistent with carpal tunnel syndrome, Total Neuropathy Score-nurse [TNSn], Mini Mental State Examination [MMSE], autonomic nervous system dysfunction history, and carpal tunnel syndrome questionnaire), joint-related event evaluations (joint examinations and radiographs), numerical rating scale (NRS) for nonstudy joint pain, electrocardiograms (ECGs), physical examinations, and injection-site reactions. This study was conducted in accordance with the ethical principles that have their origin in the declaration of Helsinki and that are consistent with Good Clinical Practice (GCP) and applicable regulatory requirements.

    		 Change From Baseline Through Week 20 in Daily Numerical Rating Scale (NRS) Score
    End point description
    The numerical rating scale (NRS) uses an 11-point scale to assess OA pain ranging from 0 to 10 with high scores representing greater symptom severity (0=no pain and 10=pain as bad as you can imagine). The ITT analysis set was defined as all randomized subjects who received at least 1 dose of study drug. Here 'n' signifies number of subjects who were evaluable for this outcome measure at specific timepoint.

    The WOMAC 3.1 is a multi-dimensional, osteoarthritis (OA) specific self-administered questionnaire using 24 questions with a 48-hour recall that are grouped into 3 subscales (pain, stiffness, and physical function) associated with hip or knee OA. Pain, stiffness, and physical function is rated on a scale of 0-10, where 0=no stiffness to 10=extreme stiffness in the WOMAC stiffness subscale score.

    		 Change from Baseline Through Double-blind Phase in Medical Outcomes Study (MOS) Sleep Subscale Scores
    End point description
    The MOS Sleep Scale (acute version) contains 12 items that address aspects of sleep. Six subscale scores may be calculated including: daytime somnolence, sleep disturbances, snoring, shortness of breath or headache upon awaking, adequacy of sleep and amount of sleep plus a summary index of sleep disturbances. A higher score indicates worse sleep in most domains, but the amount of sleep and adequacy of sleep are scored in the opposite direction. The primary subscale of interest in this study is daytime somnolence. The ITT analysis set was defined as all randomized subjects who received atleast 1 dose of study drug.
