Part 1: Overall Response Rate (ORR)Secondary· Baseline up to 8 months
ORR was defined as the percentage of participants achieving complete response (CR) and partial response (PR) as assessed by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), CR was defined as disappearance of all lesions, PR was defined as at least a 30% decrease in the sum of the longest diameter (LD) of lesions, taking as reference the baseline sum LD.
Part 1: Progression-free Survival (PFS)Secondary· From the date of randomization to the date of first documentation of PD or death due to any cause, whichever occurred first (up to 8 months)
PFS was defined as the time from the date of randomization to the date of first documentation of PD or death due to any cause, whichever occured first. Per RECIST V1.1, PD was defined as at least a 20% increase in the SoD (Sum of Diameters) of target lesions, taking as a reference the smallest (nadir) SoD since (and including) baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 millimeter (mm).
Part 1: Disease Control Rate (DCR)Secondary· Baseline up to 8 months
DCR was defined as the percentage of participants with CR, PR plus stable disease (SD) greater than or equal to (\>=) 1 post baseline computed tomography (CT) scan evaluation from treatment initiation to qualify for DCR. Per RECIST v 1.1, CR was defined as disappearance of all lesions. PR was defined as at least a 30% decrease in the sum of the LD of lesions, taking as reference the baseline sum LD. PD was defined as at least a 20% increase in the SoD of target lesions, taking as a reference the smallest (nadir) SoD since (and including) baseline. In addition to the relative increase of 20%, t
Part 1: Percentage of Participants With Serious Adverse Events (SAEs), Treatment-emergent Adverse Events (TEAEs), and TEAEs Leading to Discontinuation or Dose ModificationSecondary· From the start of the study drug up to Day 30 after the last dose of study drug (up to 8 months)
Part 1: Percentage of Participants With Grade 3 or Higher TEAEsSecondary· From the start of the study drug up to Day 30 after the last dose of study drug (up to 8 months)
An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A treatment-emergent adverse event (TEAE) was defined as an adverse event with an onset that occurs after receiving study drug. A severity grade was defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0. As per NCI-CTCAE, Grade 1 scales as Mild; Grade 2 scales as Moderate; Grade 3 scales as severe or medically significant but not immediately life threatening; Grade 4 s
Part 1: Percentage of Participants With Shift From Baseline Values to Post-baseline Values in Laboratory ParametersSecondary· From the start of the study drug up to Day 30 after the last dose of study drug (up to 8 months)
Time frame: TEAEs are adverse events (AE) that started after the first dose of study drug up to 30 days after the last dose of study drug (up to 8 months).
Reporting threshold: 0%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of this study is to estimate the relative bioavailability of TAK-931 tablets in reference to powder-in capsule (PIC) and to assess the effect of food and esomeprazole on the pharmacokinetics (PK) of TAK-931 as a tablet.
