Abstract
BackgroundTumor necrosis factor (TNF)-α is one of principal proinflammatory cytokines involved in pathogenesis of different inflammatory arthropathies as Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) and Ankylosing Spondylitis (AS). Biotechnological drugs, represented among others by monoclonal antibodies directed against TNF-α, lead to a revolution in RA and spondylarthritis treatment. They were the first biological drugs used to treat these diseases, with good results in terms of safety and efficacy. Also because of high cost of these drugs, for some years biosimilars have been introduced in clinical practice. Biosimilars are less expensive (in Italy, less of 30% than bioriginators); they underwent to a severe process of “comparability” to assess safety and efficacy like their originators. In Italy, AIFA authorized SB4 (etanercept biosimilar), SB5 and ABP501 (adalimumab biosimilars) after passing III-phase randomized clinical trials; but real-life data and registers are lacking.ObjectivesAim of this study is to compare biosimilars and bioriginators in terms of safety and efficacy in a real-life contest.MethodsWe consequently enrolled patients, affected by inflammatory arthropathies (RA, PsA, AS) and treated with biosimilars (SB4, ABP501), belonging to any of the main biological prescribing centers in the Lazio region, from 2017 to 2020. Moreover, we enrolled patients, affected by same inflammatory diseases, but treated with corresponding originator. Clinical and laboratory data as well as disease activity indices, were collected at recruitment (T0) and after 4 (T1), 8 (T2), 12 (T3) and 24 (T4) months of therapy. Adverse events were registered.ResultsThe multicenter cohort was composed by 455 patients treated with biosimilars (SB4/ABP501 276/179; F/M 307/146; naïve 56%, median age/IQR 55/46-65) and 436 treated with originators (etanercept/adalimumab 186/259, F/M 279/157, naïve 67,2%, median age/IQR 53/43-62). No differences were found about safety, but biosimilar group presented a higher number of discontinuations due to inefficacy (p<0.001), observed at all time-points. Female gender, to be smoker and b-DMARDs naïve, the initial non-response to the drug were predictive factors of reduced drug survival (p=0,05, p=0,046, p=0,001 respectively). Retention rate at 24 months was 81.1% for bioriginators and 76.5% for biosimilars (with a median retention time of 20.7 and 18.9 months, respectively) (p=0.002). Patients with remission/low disease activity achievement at T1 showed a cumulative survival of 90% to biosimilar therapy until at T4 (p=0.001); early adverse reactions instead represented an important cause of subsequent drug discontinuation (p=0.001).ConclusionReal-life data demonstrated the same safety between biosimilars and originators but a reduced biosimilar retention rate at 24 months, about 76%. Despite their loss efficacy, biosimilars could be considered valid and safe, and a good and less expensive alternative to the originators, allowing access to these innovative treatments to a wider patient population.References[1]Feldmann, M. & Maini, R.

Abstract
Background:Secukinumab (SEC) is the first interleukin-17A inhibitor showing efficacy in both ankylosing spondylitis (AS) and psoriatic arthritis (PsA) in randomised trials, but real-life data are lacking.Objectives:In this prospective observational study, we evaluated the effectiveness and safety of SEC in patients with AS and PsA in a real-life setting.Methods:From September 2018 to September 2019, data were collected from 168 consecutive outpatients at baseline (T0) and at 6 (T6) and 12 months (T12) after starting SEC (39 AS, 23%; 129 PsA, 77%).Results:Significant improvement was seen at T6 and T12 for all clinical variables, including TJC, SJC, ESR, CRP, DAPSA, ASDAS-CRP, and BASDAI, as well as in patient-reported outcomes such as VAS-pain. By multivariable regression analysis, in AS patients high BASDAI at T0 correlated with diagnostic delay (R2=0.4; p=0.009) and peripheral joint involvement (R2=0.4; p=0.04). During follow-up, reduction of BASDAI positively correlated with high ESR (R2=0.65; p=0.04). ASDAS-CRP at T0 positively correlated with high ESR (R2=0.34; p=0.004). Reduction of ASDAS-CRP from T0 to T6 correlated with current smoking status (R2=0.42; p=0.0005). In PsA patients, reduction of DAPSA score from T0 to T12 negatively correlated with the presence of metabolic syndrome (R2=0.41; p= 0.0025). Retention rate showed good drug survival and an influence of female sex (Figure 1) in the survival curve in only AS patients, but no differences based on BMI, gender and lines of treatment were observed (Figure 2). SEC was well tolerated: Eleven patients discontinued treatment for non-severe adverse events.Conclusion:We demonstrated the effectiveness and safety of SEC in patients with AS and PsA in a real-life setting for the first time. No gender differences were observed; however, less clinical improvement was seen in smokers and in patients with metabolic syndromeReferences:No references.Disclosure of Interests:Maria Sole Chimenti: None declared, giulia lavinia fonti: None declared, Paola Conigliaro: None declared, flavia sunzini: None declared, Rossana Scrivo: None declared, luca navarini: None declared, paola triggianese: None declared, giusy peluso: None declared, Palma Scolieri: None declared, rosalba caccavale: None declared, Andrea Picchianti-Diamanti: None declared, erica de martino: None declared, simonetta salemi: None declared, domenico birra: None declared, Alessio Altobelli: None declared, marino paroli: None declared, Vincenzo Bruzzese: None declared, Bruno Laganà: None declared, Elisa Gremese Speakers bureau: Abbvie, BMS, Celgene, Jannsen, Lilly, MSD, Novartis, Pfizer, Sandoz, UCB, fabrizio conti Speakers bureau: BMS, Lilly, Abbvie, Pfizer, Sanofi, Antonella Afeltra: None declared, Roberto Perricone: None declared

Abstract
Twenty-eight patients with low-moderate, stable rheumatoid arthritis (RA), under treatment with tumor necrosis factor (TNF) alpha blockers, were immunized at least once with non-adjuvanted trivalent influenza vaccine during three consecutive influenza seasons. Antibodies toward A influenza antigens significantly increased and reached protective levels, still detectable 6 months after vaccination, both in RA patients and healthy controls. Response to B antigen instead was only observed from the second year for healthy controls and in the third year for patients. No significant difference in disease activity and anti-nuclear antibodies was observed as a consequence of vaccine administration, whereas T regulatory cells showed a significant increase 30 days after immunization in RA patients. This study confirms safety of influenza vaccine administration in RA patients treated with TNFalpha blockers. The cohort follow-up revealed the overcoming of poor B vaccine antigen immunogenicity via repeated vaccinations. Finally, protective antibody response was still observed 6 months after vaccination.
