Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Part 1: Number of Participants Who Experience a Dose Limiting Toxicity (DLT) [ Time Frame: Day 1 to Day 28 ]
  2. Part 1: Number of Participants Who Experience a Treatment-emergent Adverse Event (TEAE) [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
    Adverse events (AEs) are defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. TEAEs are any event that occurs after the participant has received study treatment. Any clinically significant changes in vital signs, visual acuity, and clinical laboratory tests that occur after study treatment administration will be recorded as TEAEs.

  3. Part 1: Number of Participants Who Experience a Treatment-related Adverse Event [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
  4. Part 2: Objective Response (OR) Rate [ Time Frame: Up to approximately 2 years ]
    OR = complete response (CR) + partial response (PR), measured by computed tomography (CT) or magnetic resonance imaging (MRI) as determined by investigator per Response Evaluation Criteria in Solid Tumors (RECIST v1.1).


Secondary Outcome Measures :
  1. Part 1: OR Rate [ Time Frame: Up to approximately 2 years ]
    OR = CR + PR, measured by CT or MRI as determined by investigator per RECIST v1.1.

  2. Parts 1 and 2: Disease Control (DC) Rate [ Time Frame: Up to approximately 2 years ]
    DC = CR, PR, or stable disease (SD).

  3. Parts 1 and 2: Duration of Response (DOR) [ Time Frame: Up to approximately 2 years ]
    DOR, defined as the time from first documentation of OR (as determined by investigator per RECIST v1.1) until the first documentation of disease progression or death due to any cause, whichever occurs first. Only participants who have achieved OR will be evaluated for DOR. DOR will be censored at the last evaluable post-baseline tumor assessment prior to subsequent anticancer therapy.

  4. Parts 1 and 2: Time to Response [ Time Frame: Up to approximately 2 years ]
  5. Parts 1 and 2: Progression-free Survival (PFS) [ Time Frame: Up to approximately 2 years ]
    PFS, defined as time from first dose of investigational product until the first documentation of radiologic disease progression or death due to any cause. PFS will be censored at the last evaluable post-baseline tumor assessment prior to subsequent therapy. Progression will be based on RECIST v1.1 (derived utilizing investigator tumor assessments).

  6. Parts 1 and 2: Overall Survival (OS) [ Time Frame: Up to approximately 2 years ]
    OS, defined as time from first dose of investigational product until death from any cause. Participants still alive will be censored at the date last known to be alive.

  7. Part 2: Number of Participants Who Experience a TEAE [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
    AEs are defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. TEAEs are any event that occurs after the participant has received study treatment. Any clinically significant changes in vital signs, visual acuity, and clinical laboratory tests that occur after study treatment administration will be recorded as TEAEs.

  8. Part 2: Number of Participants Who Experience a Treatment-related AE [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
  9. Parts 1 and 2: Area Under the Concentration Time Curve (AUC) of Bemarituzumab [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
  10. Parts 1 and 2: Maximum Observed Serum Concentration (Cmax) of Bemarituzumab [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
  11. Parts 1 and 2: Observed Concentration at the End of a Dose Interval (Ctrough) of Bemarituzumab [ Time Frame: Day 1 to 28 days after last dose (a maximum of 2 years) ]
