An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a clinical investigation participant administered study treatment that does not necessarily have a causal relationship with this treatment. An SAE is an AE which: * Results in death * Is life threatening * Requires hospitalization * Results in persistent or significant disability/incapacity * Is a congenital anomaly/birth defect * Is an important medical event

Number of Participants With Endocrine Related Immune Mediated AEsApproximately 27.5 MonthsImmune-mediated adverse events are AEs consistent with an immune-mediated mechanism or immune-mediated component for which non-inflammatory etiologies (eg, infection or tumor progression) have been ruled out.
