|---|---|---|---|
| Primary | Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) | Baseline up to 523 weeks | AE=any untoward medical occurrence in a participant administered a pharmaceutical product, regardless of causal relationship with it. AE can therefore be any unfavorable \& unintended sign, symptoms/disease temporally associated with use of a medicinal (investigational) product, whether or not considered related to it. SAE is any significant hazard, contraindication, or side effect that is fatal or life-threatening, requires hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is medically significant or requires intervention. The first dosing visit in the current study or randomization visit in the parent studies (NCT02028884/NCT02073279) was considered as baseline for this outcome measure. All AEs from the time of randomization in the parent studies for satralizumab-treated participants are reported here. |
| Primary | Number of Participants With Adverse Events of Special Interest (AESIs) and Selected AEs | Baseline up to 523 weeks | An AESIs included potential drug induced liver injury and suspected transmission of an infectious agent by study drug defined as any organism, virus, or infectious particle (e.g., prion protein transmitting transmissible spongiform encephalopathy), pathogenic or non-pathogenic causing clinical symptoms or laboratory findings that indicate an infection in a participant exposed to a medicinal product. Selected AEs included infections that required treatments with IV antibiotics, antifungals, or antivirals; opportunistic infections that required treatment with oral antibiotics, antifungals, or antivirals and injection related reaction. The first dosing visit in the current study or randomization visit in the parent studies (NCT02028884/NCT02073279) was considered as baseline for this outcome measure. All AEs from the time of randomization in the parent studies for satralizumab-treated participants are reported here. |
| Secondary | Number of Participants With Suicidality Assessed Using Columbia-Suicide Severity Rating Scale (C-SSRS) | Baseline up to 523 weeks | C-SSRS=assessment tool used to assess lifetime suicidality of a participant (at baseline) as well as any new instances of suicidality (since last visit). Structured interview prompts recollection of suicidal ideation, including intensity of ideation, behavior \& attempts with actual/potential lethality. Categories have binary responses (yes/no) \& include a-Wish to be Dead; b-Non-specific Active Suicidal Thoughts; c-Active Suicidal Ideation with Any Methods(Not Plan) without Intent to Act; d-Active Suicidal Ideation with Some Intent to Act, without Specific Plan; e-Active Suicidal Ideation with Specific Plan \& Intent, f-Preparatory Acts \& Behavior; g-Aborted Attempt; h-Interrupted Attempt; i-Actual Attempt(non-fatal); j-Completed Suicide. Suicidal ideation/behavior is indicated by a "yes" answer to any of listed categories. Score of 0 is assigned if no suicide risk is present. Score of 1 or higher= suicidal ideation or behavior. Categories with non-zero values are only reported here. |
| Secondary | Number of Participants With Serious Infections and Hepatotoxicity | Baseline up to 523 weeks | Hepatotoxicity was defined using the following Medical Dictionary for Regulatory Activities Standardised MedDRA Queries (MedDRA SMQs) - Cholestasis and jaundice of hepatic origin (SMQ narrow) and Drug related hepatic disorders - severe events only (SMQ narrow). The first dosing visit in the current study or randomization visit in the parent studies (NCT02028884/NCT02073279 ) was considered as baseline for this outcome measure. Data for all serious infections and hepatotoxicity from the time of randomization in the parent studies for satralizumab-treated participants are reported here. |
| Secondary | Time to First Protocol-defined Relapse (PDR) as Assessed by Investigator (iPDR) | Baseline up to 528 weeks | Time to first relapse (TFR) was defined as the time from randomization in parent studies to the first occurrence of the first iPDR. PDR=occurrence of new or worsening neurological symptoms attributable to neurological neuromyelitis optica (NMO) or NMOSD. New or worsening neurological symptoms that occur \< 31 days following onset of PDR were considered part of same relapse. The time point of relapse onset=time at which the participant experienced any new or worsening neurological symptoms representing NMOSD clinical relapse(s). For participants who did not relapse at the time of analysis, TFR was censored at the clinical cutoff date (CCOD) or at the time of withdrawal from study. The first dosing visit in current study or randomization visit in the parent studies (NCT02028884/NCT02073279) was considered as baseline.
