The primary endpoint was evaluated by determining if there was a dose-response relationship between the mBICLA response rate at Week 24 and the dose administered, using the Multiple Comparison Procedure - Modelling (MCP-Mod) methodology. The existence of several candidate parametric models was assumed and multiple comparison techniques were used to choose the model(s) most likely to represent the true underlying dose-response curve. The selected model could further be used to guide the choice of adequate doses. mBICLA responders were defined as subjects who met all of the following criteria: 1. BILAG-2004 normal improvement: all A scores at Baseline improved to B, C or D, and all B scores improved to C or D. 2. No worsening in disease activity: no new BILAG-2004 A scores and ≤ 1 new increase to B. 3. No worsening of total mSLEDAI-2K score from Baseline. 4. No significant deterioration (\< 10% worsening from Baseline) in PGA. 5. No treatment failure (including the premature

ALX-0061 is an investigational monoclonal antibody being developed for rheumatoid arthritis and systemic lupus erythematosus. It is in Phase 2 clinical development and has been studied in completed trials for these autoimmune conditions.
ALX-0061 targets the interleukin-6 receptor (IL6R), based on its clinical trial title. It is a monoclonal antibody designed to interact with this receptor, which is involved in inflammatory pathways relevant to autoimmune diseases.
ALX-0061 is being developed by Sanofi, a biopharmaceutical company listed on the stock exchange under the ticker SNY. Sanofi is conducting clinical trials to evaluate the drug's safety and efficacy.
ALX-0061 is in Phase 2 clinical development. It has completed five trials, including Phase 1 and Phase 2 studies, with no active trials currently ongoing. The drug is investigational and not yet approved.
ALX-0061 has completed several trials, including NCT01284569, a Phase 1 study in rheumatoid arthritis; NCT02101073, a Phase 1 bioavailability study; NCT02437890, a Phase 2 study in systemic lupus erythematosus; and NCT02518620, a Phase 2 open-label extension in rheumatoid arthritis.
ALX-0061 is also known as vobarilizumab. This alternative name may appear in scientific literature or clinical trial registries. The drug is being developed by Sanofi for autoimmune indications.
