However, more data are necessary on the effectiveness of ustekinumab in bio-naïve patients in real-life studies. Objectives: The aim of our study was to evaluate the effectiveness and safety of ustekinumab in patients with CD refractory or intolerant to conventional therapy and without previous exposure to biological drugs. Design: We performed a nationwide, observational, retrospective, multicentre study including patients with CD, in which ustekinumab was used as the first biological drug. Methods: The corticosteroid-free clinical and biological response and remission were analysed at weeks 16, 24, 52 and 72. Clinical remission was defined as Harvey–Bradshaw index⩽4 and biological remission as a faecal calprotectin (FC) <250mg/g and C-reactive protein (CRP) <5mg/L. Moreover, the persistence of the treatment and any adverse events were assessed. Results: In all, 84 patients were included in the study, males and females were equally distributed, with a median age of 63years [interquartile range (IQR): 51–75] and a median disease duration of 6.8years [IQR: 3.6–17.0]. The majority (86.9%) of patients were treated with ustekinumab as monotherapy, without concomitant immunosuppressive medication. The proportion of patients in corticosteroid-free clinical remission or response at weeks 16, 24, 52 and 72 was 93.3% (56/60), 86.8% (46/53), 82.2% (37/45) and 71.4% (30/42), respectively. CRP returned to normal values in 47.6%, 43.2%, 50% and 52.4% of patients at weeks 16, 24, 52 and 72, respectively. Similarly, FC was normalized in 45.5%, 45.5%, 48.6% and 50% of patients at weeks 16, 24, 52 and 72, respectively. The cumulative probability of remaining on ustekinumab treatment was 84.8% (95% confidence interval: 73.3–91.6) after 72weeks. Ustekinumab was discontinued in 10 patients (11.9%) within 72weeks of follow-up. Reasons for discontinuing treatment were lack of response (n=4), adverse events (n=4) and death (n=2). There were no discontinuations because of stable remission. Conclusions: Ustekinumab was effective and safe in Spanish bio-naïve CD patients, showing a quicker and more durable response than obtained in patients with previous biological treatment. In this cohort of bio-naïve patients starting on ustekinumab, the average age was high. |
