Background: This analysis evaluated long-term safety findings from the SAkuraSky and SAkuraStar studies with satralizumab in patients with neuromyelitis optica spectrum disorder (NMOSD). Methods: SAkuraSky (satralizumab in combination with baseline immunosuppressive therapy; IST) and SAkuraStar (satralizumab monotherapy) are international, multicenter, randomized, placebo-controlled, phase 3 studies consisting of a double-blind (DB) period followed by an open-label extension (OLE). The overall satralizumab treatment (OST) period safety population comprised patients receiving >= 1 dose of satralizumab in the DB and/or OLE periods (cut-off date: 22 February 2021). Safety was evaluated in the DB and OST periods. Results: In the SAkuraSky DB period, patients received satralizumab (n=41) or placebo (n=42) in addition to stable baseline IST; 75 patients were included in the OST population. In the SAkuraStar DB period, 63 patients received satralizumab monotherapy and 32 received placebo; 91 patients were included in the OST population. Median treatment exposure in the OST period was 4.4 years (range 0.1-7.0) in SAkuraSky and 4.0 years (range 0.1-6.1) in SAkuraStar. Rates of adverse events (AEs per 100 patient-years) and serious AEs in the OST period were comparable with satralizumab and placebo in the DB periods of both studies. Similarly, overall rates of infections and serious infections were consistent between the OST and DB periods with satralizumab, with no increase in rates of infections or serious infections over time. In the OST periods, longer exposure to satralizumab was not associated with a higher risk of severe (grade >= 3) laboratory changes versus the DB periods. No deaths or anaphylactic reactions to treatment with satralizumab were reported during the OST periods of both studies. Conclusion: The safety profile of satralizumab as a monotherapy or in combination with IST was maintained in the OLE, and no new safety concerns versus the DB period were observed

Abstract

Background: This analysis evaluated long-term safety findings from the SAkuraSky and SAkuraStar studies with satralizumab in patients with neuromyelitis optica spectrum disorder (NMOSD). Methods: SAkuraSky (satralizumab in combination with baseline immunosuppressive therapy; IST) and SAkuraStar (satralizumab monotherapy) are international, multicenter, randomized, placebo-controlled, phase 3 studies consisting of a double-blind (DB) period followed by an open-label extension (OLE). The overall satralizumab treatment (OST) period safety population comprised patients receiving >= 1 dose of satralizumab in the DB and/or OLE periods (cut-off date: 22 February 2021). Safety was evaluated in the DB and OST periods. Results: In the SAkuraSky DB period, patients received satralizumab (n=41) or placebo (n=42) in addition to stable baseline IST; 75 patients were included in the OST population. In the SAkuraStar DB period, 63 patients received satralizumab monotherapy and 32 received placebo; 91 patients were included in the OST population. Median treatment exposure in the OST period was 4.4 years (range 0.1-7.0) in SAkuraSky and 4.0 years (range 0.1-6.1) in SAkuraStar. Rates of adverse events (AEs per 100 patient-years) and serious AEs in the OST period were comparable with satralizumab and placebo in the DB periods of both studies. Similarly, overall rates of infections and serious infections were consistent between the OST and DB periods with satralizumab, with no increase in rates of infections or serious infections over time. In the OST periods, longer exposure to satralizumab was not associated with a higher risk of severe (grade >= 3) laboratory changes versus the DB periods. No deaths or anaphylactic reactions to treatment with satralizumab were reported during the OST periods of both studies. Conclusion: The safety profile of satralizumab as a monotherapy or in combination with IST was maintained in the OLE, and no new safety concerns versus the DB period were observed
