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   44380   clinical trials with a EudraCT protocol, of which   7392   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.

    Recruitment
    Recruitment details
    The study comprised 2 periods: Period 1 (double-blind, placebo-controlled, efficacy and safety period [acute treatment phase]) and Period 2 (open-label safety period [long-term safety phase]).

    Pre-assignment
    Screening details
    Per planned analysis, the safety analysis was performed separately for Period 1 and for the integrated trial period. Integrated trial period included all participants who received 1 of the 3 TV-44749 treatments in Period 1 and all randomized participants to Period 2 who received at least 1 dose of TV-44749.

    Notes
    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: Not all participants who completed Period 1, continued to Period 2.

    Double-blind Period: Change in the Positive and Negative Syndrome Scale (PANSS) Total Score From Baseline to Week 8
    End point description
    PANSS is a 30-item scale used to evaluate positive and negative symptoms of schizophrenia. Each item was scored on a 7-point scale ranging from 1 (absent) to 7 (extreme). Positive symptom scale includes 7 items with a maximum score of 49; negative symptom scale includes 7 items with a maximum score of 49; and general psychopathology scale includes 16 items with a maximum score of 112. Total score was sum of 30-item scale, ranging from 30 (absent) to 210 (extreme), with a higher score indicating greater severity of symptoms. Least square (LS) mean was calculated using a repeated measures model with treatment, study visit, treatment visit interaction, stratification variables (sex and geographic region), age, and PANSS total score at baseline as covariates. Full Analysis Set included all participants randomized to study arms in Period 1 regardless of actual treatment the participant received. 'Number of participants analyzed' = participants evaluable for this endpoint.

    Double-blind Period: Change in Personal and Social Performance Scale (PSP) Score From Baseline to Week 8
    End point description
    PSP is a 100-point single-item rating scale, divided into 10 equal intervals, where 0 (grossly impaired functioning) to 100 (excellent functioning). Score was based on assessment of participant’s functioning in 4 categories: 1) socially useful activities, including work and study; 2) personal and social relationships; 3) self-care; and 4) disturbing and aggressive behaviors. Higher scores represented better personal and social functioning, with ratings from 91 to 100 indicating more than adequate functioning, while scores under 30 indicating poor functioning that required intensive supervision. LS mean was calculated using a repeated measures model with treatment, study visit, treatment visit interaction, stratification variables (sex and geographic region), age, and PSP score at baseline as covariates. Full Analysis Set: all participants randomized to study arms in Period 1 regardless of the actual treatment received. 'Number analyzed' = participants evaluable for this endpoint.

    Double-blind Period: Patient Global Impression-Improvement (PGI-I) Scale Score at Weeks 2, 4, and 8
    End point description
    The PGI-I scale is a 1-item participant-rated instrument that measures improvement of the participant’s disease. The participant rated the perceived change in his/her condition in response to therapy on a scale of 1 to 7, where 1=very much better, 2=much better, 3=a little better, 4=no change, 5=a little worse, 6=much worse, 7=very much worse. LS mean was calculated using a repeated measures model with treatment, study visit, treatment visit interaction, stratification variables (sex and geographic region), age, and PGI-I score at baseline as covariates. Full Analysis Set included all participants randomized to Period 1 regardless of the actual treatment the participants received. 'Number of participants analyzed' = participants evaluable for this endpoint. 'n' = participants evaluable at specified timepoint.

    Double-blind Period: Change in Schizophrenia Quality of Life Scale (SQLS) Total Score From Baseline to Weeks 4 and 8
    End point description
    The SQLS Revision 4 was administered to capture quality of life. The 33-item measure yields subscales pertaining to psychosocial (20 items) and cognition/vitality factors (13 items). Each item was scored on a 5-point scale (1 - never, 2 - rarely, 3 - sometimes, 4 - often, 5 - always). Individual domain and total scores were standardized by scoring algorithm from 0 (best health status) to 100 (worst health status) scale, with higher scores indicating comparatively lower quality of life. Full Analysis Set included all participants randomized to Period 1 regardless of the actual treatment the participants received. 'Number of participants analyzed' = participants evaluable for this endpoint. 'n' = participants evaluable at specified timepoint.

    Double-blind Period: Change in PSP Score From Baseline to Week 4
    End point description
    PSP is a 100-point single-item rating scale, divided into 10 equal intervals, where 0 (grossly impaired functioning) to 100 (excellent functioning). Score was based on assessment of participant’s functioning in 4 categories: 1) socially useful activities, including work and study; 2) personal and social relationships; 3) self-care; and 4) disturbing and aggressive behaviors. Higher scores represented better personal and social functioning, with ratings from 91 to 100 indicating more than adequate functioning, while scores under 30 indicating functioning so poor that intensive supervision was required. LS mean was calculated using repeated measures model with treatment, study visit, treatment visit interaction, stratification variables (sex and geographic region), age, and PSP score at baseline as covariates. Full Analysis Set: all participants randomized to Period 1 regardless of actual treatment received. 'Number of participants analyzed' = participants evaluable for this endpoint.

    The AIMS is a 14-item scale that includes assessments of orofacial movements, extremity and truncal dyskinesia, examiner’s judgment of global severity, subjective measures of awareness of movements and distress, and a yes/no assessment of problems concerning teeth and/or dentures. AIMS total score was calculated as a sum of items 1 through 7. Items 1 through 7 included facial and oral movements (Items 1-4), extremity movements (Items 5-6), and trunk movements (Item 7). Each item was rated from 0 (none) to 4 (severe) The AIMS total score for Items 1-7 ranged from 0 (no dyskinesia) to 28 (severe dyskinesia) with a higher score indicating greater severity of the condition.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    15 Feb 2024
    The primary reason for this amendment was to describe the course of action for Period 2 participants following the completion of the Period 1 efficacy analyses and the top line results availability. This amendment also provided clarity to assessments and processes in several sections. Changes to the protocol were considered to have no negative impact on the safety of participants already enrolled into the trial and to not have confounded the interpretation of safety data collected from participants currently enrolled in Period 2 of the trial following implementation of Protocol Amendment 1.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
