Design outcomes
Primary
| Measure | Time frame |
|---|---|
| PFS, defined as the time from randomization to the first occurrence of disease progression, as determined by the investigator according to RECIST v1.1, or death from any cause (whichever occurs first). | — |
Secondary
| Measure | Time frame |
|---|---|
| • ORR, defined as the proportion of participants with a CR or a PR on two consecutive occasions >= 4 weeks apart, as determined by the investigator according to RECIST v1.1 • DOR, defined as the time from the first occurrence of a confirmed objective response to the first occurrence of disease progression, as determined by the investigator according to RECIST v1.1, or death from any cause, whichever occurs first • OS, defined as the time from randomization to death from any cause • PFS rate at 12 months, defined as the proportion of participants who have not experienced disease progression or death from any cause at 12 months after randomization, as determined by the investigator, according to RECIST v1.1 • OS rate at 12 months, defined as the proportion of participants who have not experienced death from any cause at 12 months after randomization • Incidence and severity of adverse events, with severity determined according to NCI CTCAE v5.0 • Change from baseline in targeted clinical laboratory test results • Change from baseline in targeted vital signs • PK profiles and parameters derived for RO7247669 including but not limited to, when appropriate and when data allow, the parameters listed below: - Maximum concentration - Time of maximum concentration - Clearance - Volume of distribution at steady state - Area under the concentration-time curve - Half*life • Incidence and titer of RO7247669 ADA during the study relative to the prevalence of ADA at baseline and impact of ADAs on exposure, activity and safety | — |
