| E.5 End points |
| E.5.1 | Primary end point(s) |
Primary Endpoint:
Progression-free survival (PFS): time from randomization date to date of disease progression per the modified RECIST criteria or death. Subjects not meeting criteria for progression by the analysis data cutoff date will be censored at their last evaluable disease assessment date.
Secondary Endpoints:
Objective Response Rate (ORR): The incidence of either a confirmed complete response (CR) or partial response (PR) per modified RECIST criteria (responder). A confirmed CR requires two consecutive assessments of CR at least 28 days apart. A confirmed PR requires two assessments at least 28 days apart of PR or CR. All subjects that do not meet the criteria for an objective response by the analysis cutoff date will be considered non-responders.
Duration of response (DOR): (calculated only for those subjects with an objective response) time from first confirmed objective response to disease progression per the modified RECIST criteria.
Subjects not meeting criteria for progression by the analysis data cutoff date will be censored at their last evaluable disease assessment date.
Change in continuous measures of tumor burden
Time-adjusted area under the curve (AUC) for the FACT-Kidney Cancer Symptom Index (FKSI-
15) scale score from baseline through disease progression with imputation for missing data.
Incidence of AEs and significant laboratory changes
Incidence of the occurrence of anti-AMG 386 antibody formation
Tertiary Endpoints:
Overall survival: time from randomization date to date of death. Subjects who have not died by the analysis data cutoff date will be censored at their last contact date.
Time to progression (TTP): time from randomization date to date of disease progression per the modified RECIST criteria. Subjects not meeting criteria for progression by the analysis data cutoff date will be censored at their last evaluable disease assessment date.
Time to response: time from randomization date to date of first objective response for confirmed responders. Non-responders by the analysis data cutoff date with a best response of SD will be censored at their last assessment of SD, and subjects with a best response of PD will be censored at the maximum observed time to a first confirmed response among all responders.
