  • Data are n (%) of patients.

  • Except for the number of adverse events, patients were counted once per treatment in each row. Serious adverse events were defined as any untoward medical occurrence at any dose that results in death, is life threatening, requires inpatient hospitalisation or prolongation of existing hospitalisation, results in persistent or significant disability/incapacity, or results in congenital anomaly. Severe adverse events were those that interfered significantly with the patient’s usual function, as determined by the investigator.

  • *Events are counted up to 28 days beyond the last dose.

  • †Reviewed by an external adjudication committee; malignancies excluding non-melanoma skin cancer were metastatic thyroid cancer and prostate cancer; the non-melanoma skin cancer was basal cell carcinoma.

  • ‡All herpes zoster events reported involved one or two adjacent dermatomes and were non-serious.
