Every 8 weeks for first 48 weeks, then every 12 weeks until radiological disease progression. Assessed up to date of DCO (05Jan24) to a maximum of approximately 63 months

What was measured

Percentage of evaluable patients with at least one BICR assessed visit response of complete response (CR) or partial response (PR). CR defined as disappearance of all target lesions (TL) since baseline. Any pathological lymph nodes selected as TLs must have a reduction in short axis to \<10mm. PR defined as \>= 30% decrease in the sum of diameters of target lesions (compared to baseline sum of diameters). Responses include both confirmed and unconfirmed BICR responses
