Study population: Patients with RA who are going to commence treatment with Ro-Actemra® (Tocilizumab). All patients initiating treatment will be considered for the study if they fulfill all inclusion/exclusion criteria.

Who may be able to join

  • Diagnosis of moderate to severe active RA of ≥6 months duration.
  • Patients who have commenced treatment with Ro-Actemra® (tocilizumab) in accordance with the approved Summary of Product Characteristics.
  • Age > 18 years.
  • Body weight ≤150 kg.
  • Non-pregnant, non-nursing female, and females of child-bearing potential must use a reliable means of contraception, eg, physical barrier (patient and partner), contraceptive pill or patch, spermicide and barrier, or intrauterine device (IUD)
  • If female and of childbearing potential, the patient must have a negative urine at screening and baseline.

  • If patients are receiving an oral corticosteroid, the prednisone dose or its equivalent must be ≤10 mg/day and stable for ≥28 days prior to screening.
  • If patients are currently taking a permitted non-biologic DMARD, the dose must be stable for ≥7 weeks prior to baseline. Willing to receive oral folate or leucovorin if taking methotrexate.
  • Patients who have been given written information about the study and have consented to data collection and review.

Who cannot join

  • History of autoimmune disease or inflammatory joint disease other than RA.
  • Treatment with any investigational agent within 4 weeks (or 5 half-lives of investigational agent, whichever is longer) before starting treatment with Ro-Actemra®
  • Pregnant women or nursing (breastfeeding) mothers
  • Major surgery (including joint surgery) within 8 weeks prior to screening or planned major surgery within 6 months following randomization.
  • Functional class IV as defined by the ACR Classification of Functional Status in RA (ie, largely or wholly incapacitated with patient bedridden or confined to wheel chair, permitting little or no self-care)
  • Treatment with rituximab within 6 months before screening.
Show all 17Show fewer
  • Treatment with IV gamma globulin, plasmapheresis or Prosorba® column within months, or any investigational cell-depleting therapies before baseline.
  • Immunization with a live/attenuated vaccine within 4 weeks prior to baseline.
  • Any previous treatment with alkylating agents, such as cyclophosphamide or chlorambucil, or with total lymphoid irradiation.
  • Treatment with:
  • Intraarticular (IA) corticosteroids within 8 weeks prior to screening. Intramuscular (IM) or IV corticosteroids within 12 weeks prior to screening.
  • History of severe allergic or anaphylactic reactions to human, humanized, or murine monoclonal antibodies.
  • Evidence of serious uncontrolled concomitant cardiovascular, nervous system, pulmonary (including obstructive pulmonary disease), renal, hepatic, endocrine(including uncontrolled diabetes mellitus) or GI disease (including complicated
  • Evidence of active malignant disease, malignancies diagnosed within the previous 5 years (including hematological malignancies and solid tumors, except non melanoma skin cancer that has been excised and cured), or breast cancer diagnosed within the previous 5 years.
  • Active TB requiring treatment within the previous 3 years. Patients previously treated for TB with no recurrence in the past 3 years are permitted. Patients who have a positive purified protein derivative (PPD) tuberculin skin test and have not been adequately treated for TB must be treated for latent TB with isoniazid (INH) for 1 month prior to enrollment whether or not they have been vaccinated in the past. Patients with a positive PPD that is ≥5mm at screening are not eligible for the study unless they begin treatment for latent TB with INH a minimum of 1 month prior to enrollment in the trial. The required total INH treatment duration is 9 months. Patients must have a negative CXR at enrollment.
  • HIV-positive.
  • History of alcohol, drug or chemical abuse within the 6 months prior to screening.

About this study

Official title: Regulation of the Immune System in Response to the Treatment With Tocilizumab in RA Patients

The purpose of this study is to know the level of expression and activation state of different transcription factors of the STAT family (STAT1, STAT3, STAT5A, STAT5B, STAT6) in the hematopoietic cells from tocilizumab treated patients.

Arthritis, Rheumatoid

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in the levels of phosphorylation of STAT proteins on peripheral blood leukocytes

    The levels of phosphorylation of STATs on different subsets of leukocytes will be assessed by flow cytometry at baseline (before Tocilizumab administration) and at the indicated time (6m) after initiation of treatment. Results will be expressed as Mean of Fluorescence Intensity. To perform the analysis the investigators will use conjugated monoclonal antibodies against STAT1, STAT3, STAT5 and STAT6

    Measured: 6 months

Secondary outcomes (1)
  1. Main change in plasma level of IL-2, IL-4, IL-6, IL-10, IL-17, TNFα, IFNα, IFNγ,MCP-1 and IL-1

    Measured: Baseline, at month 6 and 12

Questions about this trial

What is this clinical trial studying?

An observational study of Rheumatoid Arthritis, run by Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in the levels of phosphorylation of STAT proteins on peripheral blood leukocytes (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Nov 2016.
