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   44334   clinical trials with a EudraCT protocol, of which   7366   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 ).

    		 Change From Baseline in Clinical European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (clinESSDAI) Score at Week 24
    End point description
    In clinESSDAI, physician scores the systemic disease activity level on 11 organ-specific domains (constitutional, lymphadenopathy and lymphoma, articular, muscular, cutaneous, glandular, pulmonary, renal, peripheral nervous system, central nervous system, and hematological), with each domain activity in 3 to 4 levels (no, low, moderate, high) according to their severity (0 = no disease activity; 3 or 4 = high disease activity). Each domain was assigned a weight between 1 and 7, and domain score was multiplied by domain weight. A higher score indicates worsening of the disease. Sum of the weighted domain scores is the overall score, which can range from 0 to 135. The full analysis set (FAS) included all randomised subjects who had received at least 1 dose (partial or complete) of any study intervention. Here, 'N' (number of subjects analysed) signifies subjects who were evaluable for this endpoint.

    		 Change From Baseline in EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) Score at Week 24
    End point description
    Change from baseline in ESSPRI score at Week 24 was reported. The ESSPRI was a patient-reported assessment of the severity of dryness, fatigue, and pain associated with primary sogrens syndrome. Subjects were asked to rate the severity of dryness, fatigue and pain over the past 2 weeks on a numeric rating scale (NRS), ranging from 0 “no symptom" to 10 “maximal imaginable" symptoms (dryness, fatigue, pain). Each domain was scored on scale of 0 to 10 (0 =no symptom at all and 10 = worst symptom imaginable). A total score was calculated as the mean of the 3 individual domain scores, where all domains carry the same weight. Minimum score can be 0 and maximum score can be 10, where higher ESSPRI scores indicated more severe symptoms. The FAS included all randomised subjects who had received at least 1 dose (partial or complete) of any study intervention. Here, 'N' (number of subjects analysed) signifies subjects who were evaluable for this endpoint.

    ESSDAI was a validated tool used in clinical studies to measure systemic disease activity in subjects with primary Sjogren's syndrome.

    End point description
    Number of subjects with improvement of >= 4 points from baseline in clinESSDAI score (minimal clinically important improvement) at Week 24 were reported. In clinESSDAI, physician scores the systemic disease activity level on 11 organ-specific domains (constitutional, lymphadenopathy and lymphoma, articular, muscular, cutaneous, glandular, pulmonary, renal, peripheral nervous system, central nervous system, and hematological), with each domain activity in 3 to 4 levels (no, low, moderate, high) according to their severity (0 = no disease activity; 3 or 4 = high disease activity). A higher score indicates worsening of the disease. Each domain is assigned a weight between 1 and 7, and the domain score is multiplied by the domain weight. Sum of the weighted domain scores is the overall score, which can range from 0 to 135. FAS included all randomised subjects who had received at least 1 dose (partial or complete) of any study intervention.

    		 Percentage of Subjects With ESSPRI Response Defined as a Decrease of one Point or a Decrease of >= 15 Percent (%) in the ESSPRI Score From Baseline (Minimal Clinically Important Improvement) at Week 24
    End point description
    Percentage of subjects with ESSPRI response defined as a decrease of one point or a decrease of >= 15% from baseline (minimal clinically important improvement) at Week 24 was reported. The ESSPRI was a patient-reported assessment of the severity of dryness, fatigue, and pain associated with primary sjogren's syndrome. Subjects were asked to rate the severity of dryness, fatigue and pain over the past 2 weeks on a NRS, ranging from 0 “no symptom” to 10 “maximal imaginable" symptoms (dryness, fatigue, pain). Each domain was scored on scale of 0 to 10 (0 =no symptom at all and 10 = worst symptom imaginable). A total score was calculated as the mean of the 3 individual domain scores, where all domains carry the same weight. Minimum score can be 0 and maximum score can be 10, where higher ESSPRI scores indicated more severe symptoms. The FAS included all randomised subjects who had received at least 1 dose (partial or complete) of any study intervention.

    		 Number of Subjects With Clinically Significant Abnormalities in Vital Signs
    End point description
    Number of subject with clinically significant abnormalities in vital signs were reported. Vital sign parameters including temperature (less than [<]36 and greater than [>] 38), pulse rate (<=50 beats per minute [bpm] and with >=15 bpm decrease from baseline and >=120 bpm and with >=15 bpm increase from baseline), and blood pressure (systolic blood pressure [SBP]: <=90 millimeters of mercury [mmHg] and with >=20 mmHg decrease from baseline and diastolic blood pressure [DBP]: <=50 mmHg and with >=15 mmHg decrease from baseline and >=100 mmHg and with >=15 mmHg increase from baseline). The safety analysis set included all randomised subjects who had received at least 1 dose (partial or complete) of any study intervention. Only those categories in which at least 1 subject had data were reported.

    		 Serum Nipocalimab Concentration Over Time [1]
    End point description
    Serum concentrations of nipocalimab over time in subjects receiving active study intervention will be reported. The pharmacokinetics (PK) analysis set was defined as all randomised subjects who had received at least 1 complete dose of nipocalimab and have at least 1 valid post-dose blood sample drawn for PK analysis. This endpoint was planned to be analysed for specified arms only. Here, N: number of subjects evaluable for this endpoint and n: number of subjects evaluable for each arm at specific time points.

    Notes
    [1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: The data was planned to be analysed for specified arms only.
