The aim was evaluating the effectiveness of tofacitinib in RA as first-line treatment (after conventional DMARDs) in a real-life setting in Colombian (Latin-American) patients.Patients and Methods: Retrospective cohort study conducted at a specialized center for RA management. A complete statistical analysis was performed to compare the values of the change in the DAS28 at months 3, 6, and 12 in both treatment groups.Results: A total of 152 RA patients who received tofacitinib: first-line 85 patients (55.9%) after failure on conventional DMARDs or second-line 67 patients (44.1%) after failure on biologic DMARDs. Comparative analysis of response to treatment showed a reduction in DAS28 at 3, 6, and 12 months in both study groups without statistical differences, but a higher proportion of first-line patients achieved remission (45% vs 23%). Nonresponse at three months were associated with no response at six months of follow-up. Baseline DAS28 was significantly associated with response at 12 months (OR: 1.87, 95%CI: 1.06– 3.30, p-value 0.028). In second-line patients, response to tofacitinib was not related to number of biologic DMARDs previously used.Conclusion: Tofacitinib is an effective treatment option for patients with RA, maybe better after conventional DMARDs than after biologic therapy failure. Further studies are required to determine the role of tofacitinib in different lines of RA treatment and in other groups of patients.Keywords: tofacitinib, rheumatoid arthritis, treatment, biologics
