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   43871   clinical trials with a EudraCT protocol, of which   7290   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 the study was to compare the efficacy of ABP 654 with ustekinumab in participants with moderate to severe plaque psoriasis (Ps).
    Protection of trial subjects
    This study was conducted in accordance with International Council for Harmonisation (ICH) Good Clinical Practice (GCP) regulations/guidelines. Essential documents will be retained in accordance with ICH GCP.
    Background therapy
    		 -
    Evidence for comparator
    		 Ustekinumab belongs to the pharmacologic class of interleukin (IL)-23 and IL-12 antagonists. In the United States and the European Union, ustekinumab is approved for subcutaneous (SC) administration in the treatment of moderate to severe Ps in adults and pediatric patients (6 years or older).

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: PASI 50 non-responders were not re-randomized and were considered completed at Week 28 as per protocol.

    Static Physician Global Assessment of Psoriasis (sPGA)
    The sPGA is a 6-point scale ranging from 0 (clear) to 5 (very severe) used to measure the severity of disease (induration, scaling, and erythema). A sPGA response was defined as a sPGA value of clear (score 0) or almost clear (score 1). Higher scores represent worse symptom severity.

    PASI
    The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling; each graded on a 0-4 scale [0 = clear; 1-4 = increasing severity]) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. Higher scores represent worse symptom severity.

    		 Percentage of Participants with PASI 75 Response Throughout the Study
    End point description
    Reduction in disease was measured by PASI score. The PASI 75 response is a 75% or greater improvement (reduction in disease [PASI 75]) from baseline in PASI score. The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling; each graded on a 0-4 scale [0 = clear; 1-4 = increasing severity]) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. Higher scores represent worse symptom severity. 999999 = analysis was not pre-specified for this timepoint; N=0. Through Week 28 FAS results are presented for the FAS with available data; non-responder imputation (NRI) was used. Post Week 28 results are presented for dose intensification participants with available observed data and re-randomized FAS participants with available data (NRI was used).

    Response difference in dose intensification participants (ABP 654 – ustekinumab) was estimated by the generalized linear model adjusted for the baseline PASI and the stratification factors with an identity link was used to obtain the point estimate and 95% CI for the risk difference of PASI 75 response rate at each scheduled timepoint. Observed data was used.

    		 Percentage of Participants with PASI 100 Response Throughout the Study
    End point description
    Reduction in disease was measured by PASI score. The PASI 100 response is a 100% improvement (reduction in disease [PASI 100]) from baseline in PASI score. The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling; each graded on a 0-4 scale [0 = clear; 1-4 = increasing severity]) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. Higher scores represent worse symptom severity. -99999 and 99999 = results are not estimable as there were not enough PASI responses. 999999 = analysis was not pre-specified for this timepoint; N=0. Through Week 28 FAS results are presented for the FAS with available data; NRI was used. Post Week 28 results are presented for dose intensification participants with available observed data and re-randomized FAS participants with available data (NRI was used).

    The sPGA is a 6-point scale ranging from 0 (clear) to 5 (very severe) used to measure the severity of disease (induration, scaling, and erythema). A sPGA response was defined as a sPGA value of clear (score 0) or almost clear (score 1). Higher scores represent worse symptom severity. 999999 = analysis was not pre-specified for this timepoint; N=0. Week 12 results are presented for the FAS with available data; NRI was used.

    Generalized linear model adjusted for the baseline sPGA and the stratification factors with an identity link was used to obtain the point estimate and 95% CI for the risk difference of sPGA response rate at each scheduled timepoint in dose intensification participants. Observed data was used.

    End point description
    The percentage of BSA affected was estimated by assuming that the participant's palm, excluding the fingers and thumb, represents roughly 1% of the body's surface. 999999 = analysis was not pre-specified for this timepoint; N=0. Week 12 results are presented for the FAS with available data; LOCF imputation was used. Week 52 results are presented for dose intensification participants with available observed data and re-randomized FAS participants with available data (LOCF imputation was used).
