Methods Five-year data from the BeSt study were used, in which 508 patients with recent-onset RA were randomised into four dynamic treatment strategies, aiming at a disease activity score (DAS) ≤2.4. When DAS was <1.6 for ≥6 months, the last disease-modifying antirheumatic drug (DMARD) was tapered and discontinued. If DAS increased to ≥1.6, the last DMARD was immediately reintroduced. Results During a 5-year period, 115/508 patients (23%) achieved drug-free remission. Of these, 53 patients (46%) restarted treatment because the DAS was ≥1.6 after a median of 5 months, 59 patients (51%) remained in drug-free remission for a median duration of 23 months and 3 (3%) were lost to follow-up. In those who restarted treatment, mean (SD) DAS increased from 1.13 (0.73) at remission before tapering to 2.18 (0.65) at restart, reflecting an increase in all four components of DAS. Multivariable predictors for restarting treatment were anti-cyclic citrullinated peptide (anti-CCP), last DMARD sulfasalazine, low baseline Health Assessment Questionnaire score and high mean DAS until remission. Of the 53 patients who restarted treatment, 39 (74%) again achieved remission 3–6 months after the restart. The median (IQR) damage progression in those who restarted treatment during the year of DAS increase was 0 (0–1) Sharp-van der Heijde units. Conclusion During 5 years DAS steered treatment, nearly 25% of patients with RA achieved drug-free remission; 46% restarted DMARD monotherapy because of a relapse, the majority of whom again achieved clinical remission within 3–6 months without showing radiological progression during the relapse.
