Tdose Binding and Tocilizumab (TCZ)

May 6, 2026 updated by: Centre Hospitalier Universitaire de Nice

Non-inferiority Study of TOCILIZUMAB Administered at Standardized, Fixed-interval Doses Versus Weight-based Dosing in Patients With Low-activity or Clinically Remitted Rheumatoid Arthritis.

The investigators aim to evaluate the non-inferiority of administering tocilizumab at a fixed dose versus a weight-based dose in patients with rheumatoid arthritis in remission or with low clinical activity, after 3 months of treatment, as part of a two-center randomized trial.

Detailed Description

The investigators aim to evaluate the non-inferiority of dose-banding versus weight-based dosing of tocilizumab in patients with rheumatoid arthritis in remission or with low clinical activity, at 3 months of treatment. The secondary objectives are: To evaluate the economic benefit of dose-banding on the production of bags in the pharmacy (cost of preparing the bags), To compare the time to pharmaceutical release between the two groups, To compare the rate of bag reallocation between the two groups. This is a multicenter, prospective, randomized study evaluating the non-inferiority of administering standard doses of TOCILIZUMAB versus weight-based doses in patients with rheumatoid arthritis in remission or with low clinical activity. The patient and the clinical evaluator will be blinded. The pharmacy team performing the preparation will be open-label.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
cost
Time Frame: month 3
The cost of preparing the bags is estimated based on the preparation time, which is the sum of the time spent on sterilization, production, and bag distribution over the 3-month study period in each of the two groups. The total cost over the 3-month study period will then be divided by the number of infusions to be administered to calculate the cost per infusion in each group.
