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   43925   clinical trials with a EudraCT protocol, of which   7306   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.

    General information about the trial
    Main objective of the trial
    The purpose of this trial is to determine if the study medication, CONCERTA (methylphenidate HCl), is safe and effective in improving academic performance and behavior in children with attention deficit hyperactivity disorder (ADHD), when compared to placebo.
    Protection of trial subjects
    Safety were evaluated throughout the study by monitoring of adverse events (AEs), laboratory tests (complete blood count [CBC], complete chemistry panel, and liver function tests [LFTs]), vital signs body weight measurements, electrocardiogram and the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL) including items specifically examining suicidal thinking.

    Hour 4 Permanent Product Math Test Attempted Score (PERMP-Attempted)
    End point description
    PERMP (range: 0, 400) is a measure of academic productivity in children up to 14 years of age. These seatwork math tasks provide an objective measure of attention and accuracy in calculations. The level of difficulty is established on a screening math pretest. The subsequent laboratory school day assessments employed a series of 10-minute math tests (5 pages of 80 math problem each for a total of 400 problems available). Children were graded on the number of attempted problems. A higher number of problems attempted was indicative of greater attention to detail (higher score is preferable)

    Hour 4 Swanson, Kotkin, Alger, M-Flynn and Pelham Scale for Deportment (SKAMP-Deportment)
    End point description
    The SKAMP scale measures the manifestations of ADHD using an independent observer (teacher) rating of the child's impairment in classroom behavior. The SKAMP-Deportment (SKAMP-D) (range: 0, 36) is a sum of ratings on 6 deportment items (interacting with other children, interacting with adults, remaining quiet, staying seated, complying with the teacher’s directions, and following the classroom rules). Each item was rated on a 7-point impairment scale (0=normal, 6=maximum impairment), with higher scores indicating more severe symptoms.

    Hour 5.5 Test of Variables of Attention (TOVA) ADHD Composite Cutoff Score
    End point description
    The TOVA (range: unbounded) is a computerized, visual continuous performance test providing a measure of attention. The stimulus, presented for 100 milliseconds (ms) at the rate of 30 per minute, is a computer-presented square containing a square hole near the top (target) or bottom (non-target) edge. Higher scores indicate better performance, lower scores indicate worse performance. Clinical interpretation: an ADHD scores of -1.80 or lower (<= -1.80) are considered not within normal limits scores above -1.80 (> -1.80) are considered inconclusive (meaning, neither like-ADHD nor like-normal).

    Hour 5.5 Wide Range Assessment of Memory and Learning (WRAML-2) Finger Windows Forwards
    End point description
    WRAML-2 (range: 0, 28) is designed to evaluate a child's ability to learn and to memorize information, consists of 9 subtests from which 4 summary indexes can be calculated: verbal memory index, visual memory index, learning index, and general memory index. During this test the investigator pointed to a longer and longer series of windows on a card at the rate of 1 location per second, and then the child was asked to reproduce the sequence exactly. One point was given for each correctly recalled sequence, and the test was discontinued after 3 consecutive errors.

    Hour 5.5 Test of Variables of Attention (TOVA) Commissions Standard Score
    End point description
    The TOVA (range: unbounded) is a computerized, visual continuous performance test providing a measure of attention. The stimulus, presented for 100 milliseconds (ms) at the rate of 30 per minute, is a computer-presented square containing a square hole near the top (target) or bottom (non-target) edge. Higher scores indicated better performance, lower scores indicate worse performance. Clinical interpretation: scores below 80 are considered abnormal, 80-85 are considered borderline, and scores above 85 are considered within normal limits.

    Each child individually was given a sequence of numbers with the sequence becoming progressively longer. The child was then asked to repeat the digits in the same sequence, either forwards or backwards. Each sequence length was attempted twice. The test was complete after failure on both trials of any sequence length. One point was awarded if the participant passed only 1 trial of a sequence length. Zero points were given if the participant failed both trials. The maximum raw scores were 16 forwards and 14 backwards. A higher score was indicative of better recall and attention (range: 0, 14).

    The THS-R (range: unbounded) is a standardized, untimed assessment designed to evaluate neurosensory integration manifested in manuscript and cursive writing. The test includes subtests: writing from memory or dictation the letters of the alphabet in order, single digit-numbers out of order, selected words, and copying selected letters, words, and sentences. Each subtest was scored from zero (poorly formed letters) to 3 (perfectly formed letters). 100 is the normal mean; scores lower than 100 indicate performance worse than normal, scores above 100 indicate performance better than normal.

    End point description
    The DIBELS (range: 0, 376), used to assess reading fluency, consists of standardized, individually administered measures of early literacy development. These short (1 minute) fluency measures were developed based upon essential early literacy domains to assess development of phonological awareness, alphabetic understanding, and automaticity and fluency. Only the paragraph fluency component of an age/grade-appropriate DIBELS was used. A higher score indicated better performance, as it represented that the subject orally read a greater number of words correctly within the time allowed.

    End point description
    This task, presented once during a laboratory school day, was designed to index “attention to detail” by determining how many grammatical mistakes each child could identify and circle in a brief paragraph. The errors were not difficult to identify and were designed to show attention to task, not comprehension. A higher number of errors identified, of those possible, was indicative of better attention - identification of grammatical errors(range: 0, 1 represents correct responses divided by the number of possible responses).
