Introduction: The effectiveness of canakinumab may change according to the different times it is used after Still's disease onset. This study aimed to investigate whether canakinumab (CAN) shows differences in short- and long-term therapeutic outcomes, according to its use as different lines of biologic treatment., Methods: Patients included in this study were retrospectively enrolled from the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to Still's disease. Seventy-seven (51 females and 26 males) patients with Still's disease were included in the present study. In total, 39 (50.6%) patients underwent CAN as a first-line biologic agent, and the remaining 38 (49.4%) patients were treated with CAN as a second-line biologic agent or subsequent biologic agent., Results: No statistically significant differences were found between patients treated with CAN as a first-line biologic agent and those previously treated with other biologic agents in terms of the frequency of complete response ( p =0.62), partial response ( p =0.61), treatment failure ( p >0.99), and frequency of patients discontinuing CAN due to lack or loss of efficacy ( p =0.2). Of all the patients, 18 (23.4%) patients experienced disease relapse during canakinumab treatment, 9 patients were treated with canakinumab as a first-line biologic agent, and nine patients were treated with a second-line or subsequent biologic agent. No differences were found in the frequency of glucocorticoid use ( p =0.34), daily glucocorticoid dosage ( p =0.47), or concomitant methotrexate dosage ( p =0.43) at the last assessment during CAN treatment., Conclusion: Canakinumab has proved to be effective in patients with Still's disease, regardless of its line of biologic treatment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Vitale, Caggiano, Sfikakis, Dagna, Lopalco, Ragab, La Torre, Almaghlouth, Maggio, Sota, Tufan, Hinojosa-Azaola, Iannone, Loconte, Laskari, Direskeneli, Ruscitti, Morrone, Mayrink Giardini, Panagiotopoulos, Di Cola, Martín-Nares, Monti, De Stefano, Kardas, Duran, Campochiaro, Tomelleri, Alabdulkareem, Gaggiano, Tarsia, Bartoloni, Romeo, Hussein, Laymouna, Parente de Brito Antonelli, Dagostin, Fotis, Bindoli, Navarini, Alibaz-Oner, Sevik, Frassi, Ciccia, Iacono, Crisafulli, Portincasa, Jaber, Kawakami-Campos, Wiesik-Szewczyk, Iagnocco, Simonini, Sfriso, Balistreri, Giacomelli, Conti, Frediani, Fabiani and Cantarini.)
