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   43865   clinical trials with a EudraCT protocol, of which   7286   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
    • To provide continued treatment access to subjects with active rheumatoid arthritis (RA) who have participated for at least 16 weeks in other protocols in the rituximab-Pfizer program. • To evaluate the overall safety, tolerability and immunogenicity of PF-05280586 occurring after transition from a licensed rituximab product to PF-05280586. • To continue follow-up of biomarker and efficacy endpoints of interest in the previous B3281001 Study in the rituximab-Pfizer program contributing to this protocol.
    Protection of trial subjects
    The final protocol, any amendments, and informed consent documentation were reviewed and approved by the Institutional Review Board(s) and/or Independent Ethics Committee(s) at each of the investigational sites participating in the study. This study was conducted in compliance with the ethical principles originating in or derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonisation Good Clinical Practice Guidelines. In addition, all local regulatory requirements were followed, in particular, those affording greater protection to the safety of study participants.
    Background therapy
    Participants continued to receive a stable background regimen of methotrexate 10 to 25 mg/week (7.5 mg/week in the event of prior poor tolerance) during study participation. The use of folate supplements during study treatment was required per Standard of Care.
    Evidence for comparator
    Rituxan is the brand approved for use in the United States and will be referred to as rituximab-US, hereafter and MabThera is the brand approved for use in the European Union and will be referred to as rituximab-EU hereafter. PF-05280586 has the same primary amino acid sequence as rituximab-EU (MabThera) and rituximab-US (Rituxan) and is being developed to be similar to the licensed products.

    Recruitment
    Recruitment details
    This was an extension study for participants with active rheumatoid arthritis who had participated for at least 16 weeks in a prior rituximab-Pfizer protocol (B3281001) and had not received intervening treatment with investigational agents or other biologics (including Rituxan and MabThera).

    Pre-assignment
    Screening details
    Participants assigned to PF-05280586 in Study B3281001 continued to receive PF-05280586 in this study. Participants assigned to licensed product in Study B3281001 were assigned either the previously assigned licensed product or PF-05280586 for the first treatment course. In subsequent treatment courses, all participants were assigned PF-05280586.

    Serum samples were collected to determine the presence of ADA using two validated assays, one specific for PF-05280586 and one specific for the licensed drug products. For participants assigned to PF-05280586 in Study B3281001, blood samples were screened for ADA using the assay specific to PF-05280586; if the blood samples were confirmed to be positive for ADA against PF-05280586, the samples were also analyzed using the assay specific for the licensed drug products to assess cross-reactivity of the ADA. For participants assigned to the licensed products in Study B3281001, blood samples were screened for ADA using both assays in order to assess any product-specific ADA and/or cross-reactivity for the transition from the licensed products to PF-05280586.

    Mean Change from Initial Study Baseline in Disease Activity Score (DAS28)-C-Reactive Protein (CRP) - by the end of Course 1 [25]
    End point description
    The disease activity score (DAS) assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient’s global assessment of arthritis Visual Analog Scale (VAS). The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP equals (=) 0.56 square root (sqrt) (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 natural log [ln] (CRP [milligrams per liter, mg/L] +1) + 0.014 (global assessment of health [GH]) + 0.96. Total score range: 0 to 9.4, higher score indicated more disease activity.

    Percentage of Participants with Good European League Against Rheumatism (EULAR) Response Based on DAS28 - by the end of Course 1 [28]
    End point description
    The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders had a change from baseline greater than (>) 1.2 with present DAS28 less than or equal to (≤) 3.2; moderate responders had a change from baseline >0.6 and ≤1.2 with present DAS28 ≤3.2 or change from baseline >0.6 with present DAS28 >3.2 and ≤5.1 or change from baseline >1.2 with present DAS28 >5.1; non-responders had a change from baseline ≤0.6 with present DAS28 ≤5.1 or change from baseline ≤1.2 with present DAS28 >5.1.

    The DAS assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient’s global assessment of arthritis VAS. The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP = 0.56 sqrt (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 (ln CRP [mg/L] +1) + 0.014 (GH) + 0.96. Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-CRP ≤3.2 implied low disease activity.

    Percentage of Participants with DAS Remission (DAS28-CRP less than [<] 2.6) - by the end of Course 1 [34]
    End point description
    The DAS assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient’s global assessment of arthritis VAS. The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP = 0.56 sqrt (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 (ln CRP [mg/L] +1) + 0.014 (GH) + 0.96. Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-CRP <2.6 implied remission.

    End point description
    Sixty-eight joints were assessed by a blinded joint assessor to determine the number of joints that were considered tender or painful. For consistency, a single assessor was preferred to perform all evaluations across the study for an individual participant. The response to pressure/motion on each joint was assessed using the following scale: Present/Absent/Not Done/Not Applicable (to be used for artificial or missing joints). Artificial joints were not be assessed.

    Percent Change from Initial Study Baseline in Individual Components of the ACR response: Tender/Painful Joint Count - by the end of Course 3 [48]
    End point description
    Sixty-eight joints were assessed by a blinded joint assessor to determine the number of joints that were considered tender or painful. For consistency, a single assessor was preferred to perform all evaluations across the study for an individual participant. The response to pressure/motion on each joint was assessed using the following scale: Present/Absent/Not Done/Not Applicable (to be used for artificial or missing joints). Artificial joints were not be assessed.

    Percent Change from Initial Study Baseline in Individual Components of the ACR Response: Physician’s Global Assessment of Arthritis - by the end of Course 1 [58]
    End point description
    The investigator assessed how the participant’s overall arthritis appeared at the time of the visit. This evaluation was based on the participant’s disease signs, functional capacity and physical examination, and was independent of the Patient’s Global Assessment of Arthritis. The investigator’s response was recorded using a 100 mm VAS by placing a mark on the scale between 0 (very good) and 100 (very poor).

    Percent Change from Initial Study Baseline in Individual Components of the ACR Response: Health Assessment Questionnaire – Disability Index (HAQ-DI) - by the end of Course 1 [61]
    End point description
    The HAQ-DI assessed the degree of difficulty a participant had experienced during the past week in 8 domains of daily living activities: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consisted of 2 to 3 items. For each question in the questionnaire, the level of difficulty was scored from 0 to 3 with 0 representing “no difficulty,” 1 as “some difficulty,” 2 as “much difficulty,” and 3 as “unable to do.” Any activity that required assistance from another individual or required the use of an assistive device adjusted to a minimum score of 2 to represent a more limited functional status. This questionnaire was to be completed by the participant prior to any procedures being performed at the visit, if possible.

    Percent Change from Initial Study Baseline in Individual Components of the ACR Response: Health Assessment Questionnaire – Disability Index (HAQ-DI) - by the end of Course 3 [63]
    End point description
    The HAQ-DI assessed the degree of difficulty a participant had experienced during the past week in 8 domains of daily living activities: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consisted of 2 to 3 items. For each question in the questionnaire, the level of difficulty was scored from 0 to 3 with 0 representing “no difficulty,” 1 as “some difficulty,” 2 as “much difficulty,” and 3 as “unable to do.” Any activity that required assistance from another individual or required the use of an assistive device adjusted to a minimum score of 2 to represent a more limited functional status. This questionnaire was to be completed by the participant prior to any procedures being performed at the visit, if possible.
