Comparing the Efficacy of Periarticular Bone Structure in Patients Treated With Either Tocilizumab or Tumor Necrosis Factor Blockers (Re-Bone)

September 25, 2019 updated by: University of Erlangen-Nürnberg Medical School

Non Randomized Parallel-group Clinical Study to Compare the Efficacy of Periarticular Bone Structure in Patients Treated With Either Tocilizumab or Tumor Necrosis Factor Blockers.

Comparing the structural effects of TNFi and tocilizumab on the periarticular bone by performing a comprehensive analysis of the periarticular bone changes in RA patients treated with either TNFi or tocilizumab in a longitudinal Setting, using high-resolution peripheral quantitative computed tomography (HR-pQCT), a very sensitive method for visualizing and quantifying bone microstructure in RA patients. Quantitatively assessing the changes of erosions volume, osteophytes size and the area of cortical fenestration in a group of TNFi-treated and a group of tocilizumab- treated RA patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Inhibition of tumor necrosis factor alpha (TNF-α) and of interleukin- 6 receptor (IL-6R) emerged as highly effective cytokine blocking strategies in the treatment of rheumatoid arthritis (RA) in the last years. Both, inhibition of TNF-α (TNFi) and of the interleukin-6 receptor by tocilizumab ameliorate the signs and symptoms, reverse the elevated acute phase response and inhibit the progression of bone erosion in RA patients (1). Despite striking similarities with respect to their efficacy and safety in the treatment of RA, TNFi and tocilizumab are two entirely distinct approaches for targeting chronic inflammatory diseases in humans. This concept is highlighted by the differential response to TNFi and tocilizumab in other chronic inflammatory diseases such as psoriasis, psoriatic arthritis and spondyloarthritis, with clinical efficacy of the former but not the latter treatment modality (2). On the other hand, tocilizumab has a direct effect on the acute phase response and iron metabolism, which is not found with TNFi. Therefore, subtle differences may exist between TNFi and tocilizumab, which are relevant for the long-term treatment of RA patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Patients (ages over 18 years) with the diagnosis of RA will be screened for the presence of erosions by Routine procedure with HR-pQCT. In case of a positive scan showing the presence of erosion in the wrist or the MCP Joints and after the decision of the treatment (if either Tocilizumab or TNF-Inhibitor), patients will be enrolled into the study.

Description

Inclusion Criteria:

  • Females and males with RA erosions in the wrist and/or MCP joints
  • Must be aged ≥ 18 years at time of consent
  • Stable treatment with conventional DMARDs of at least 3 months

Exclusion Criteria:

  • Patients exposed to abatacept or rituximab in the last 12 months
  • Patients receiving glucocorticoids over 5 mg prednisolone per day
  • Patients who are younger than 18 years
  • Pregnant or lactating females
  • Patients having received an HR-pQCT examination during the last 6 months before screening
