DOR data were censored on the date of last tumor assessment on study for participants who did not have objective tumor progression and who did not die due to any cause while on study. DOR was only calculated for participant(s) with an objective response. DOR was to be summarized using the Kaplan-Meier method if data permitted. | The analysis population included all enrolled participants who received at least 1 dose of study intervention and had an objective response (CR or PR). Number of participants analyzed = number of participant(s) evaluable for this OM. | Posted | Number | Days | Cycle 1 Day 1 until disease progression, start of subsequent anti-cancer therapy or death due to any cause (maximum of approximately 45 weeks) |
