Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the efficacy of novel agent plus chemotherapy by evaluation of ORR (objective response rate) and PFS6 (proportion of participants alive and progression-free at 6 months);Secondary Objective: To evaluate the DoR (Duration of response), PFS (progression free survival), OS (overall survival), safety and tolerability, PK and immunogenicity of novel agent plus chemotherapy;Primary end point(s): ORR in response evaluable set PFS6 in full analysis set;Timepoint(s) of evaluation of this end point: At a minimum of 6 months following the last participant’s first dose in the substudy | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • DoR per RECIST 1.1 based on Investigator assessment. • PFS per RECIST 1.1 as assessed by the Investigator. • OS. • Incidence of AEs, AESIs, and SAEs; physical examination; Laboratory findings; vital signs; 12-lead ECG. • Serum concentrations of novel agent and derived PK parameters. • Incidences of ADAs against novel agent in serum.;Timepoint(s) of evaluation of this end point: Until end of study | — |
