Časové okno: From first dose of acapatamab or AMG 404 (subprotocol C only) to clinical disease progression or death from any cause (maximum duration of acapatamab treatment was 98.43 weeks/AMG 404 treatment was 105.14 weeks)
|
Clinical PFS was defined as the time from the first dose to clinical disease progression or death from any cause.
If a participant had no evaluable post-baseline or on-trial disease assessment or was on trial without PD or death recorded, clinical PFS was censored on the date of the first dose of the IP.
Otherwise, clinical PFS was censored on the date of last assessment.
The median was estimated using the Kaplan-Meier method and the 95% confidence interval was estimated using the method by Brookmeyer and Crowley.
