LUPUS-BEST - Treat-to-target in Systemic Lupus Erythematosus

This is a multicenter, national, two-armed cluster-randomized controlled trial to evaluate the effect of a treat-to-target (T2T) strategy in in systemic lupus erythematosus (SLE) on damage progression and health related quality of life (HRQoL). The study centers will be assigned 1:1 to standard of care (SoC) or remission, defined as the absence of clinical disease activity (clinical SLEDAI =0) AND prednisolone ≤5mg/day AND physician global assessment (PGA) \<0.5 on a VAS 0-3. Patient with SLE \> 18 years of age who are not in remission will be eligible. Per arm, 303 patients will be included. Intervention centers receive a standardized training on T2T and shared decision making (SDM). In the intervention centers, patients not on target enter a phase of tight control with 6-weekly visits and treatment adjustments (at least 4 visits) or until remission is reached and maintained. Patients in remission are reassessed every 12 weeks. In case of flare, they can re-enter tight control based on SDM. In the SoC arm, patients receive 3- to 6-monthly controls and treatment adjustments according to the physician's discretion. Study duration is 120 weeks using damage accrual and HRQoL as major outcomes.
