What researchers measure

Primary outcomes

  1. Progression free survival (PFS) per RECIST 1.1

    Efficacy endpoint

    Time frame: From the date of first dose until the date of objective PD per RECIST 1.1 or death, whichever came first. It will be assessed when approximately 69 PFS events have occurred (60% maturity), approximately 8 months after the last patients dosed.

Secondary outcomes

  1. Grade ≥ 3 TRAE within 6 months after the initiation of study intervention

    safety endpoint

    Time frame: From first dose to 6 months after the initiation of study intervention

  2. Overall Survival (OS)

    Efficacy endpoint

    Time frame: From the date of the first dose of study intervention until death due to any cause. It will be assessed when approximately 69 OS events have occurred (60% maturity), approximately 24 months after last participant has been assigned to study intervention.

  3. Objective Response Rate (ORR) per RECIST 1.1

    Efficacy endpoint

    Time frame: From the date of the first dose of study intervention until the date of objective PD per RECIST 1.1. It is anticipated that this analysis will be performed approximately 8 months after the last patient has been assigned to study intervention.

  4. Disease Control Rate (DCR) per RECIST 1.1

    Efficacy endpoint

    Time frame: From the date of the first dose of study intervention until the date of objective PD per RECIST 1.1. It is anticipated that this analysis will be performed approximately 8 months after the last patient has been assigned to study intervention.

  5. Duration of response (DoR) per RECIST 1.1

    Efficacy endpoint

    Time frame: From the date of response until the date of objective PD per RECIST 1.1 or death, whichever came first. It is anticipated that this analysis will be performed approximately 8 months after the last patient dosed.

  6. Progression Free Survival (PFS) per mRECIST

    Efficacy endpoint

    Time frame: From the date of the first dose until the date of objective PD per mRECIST or death, whichever came first. It will be assessed when approximately 69 PFS events have occurred (60% maturity), approximately 8 months after the last patients dosed.
