Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DOR) | Up to 44 weeks | The DOR was defined as the duration of time from the first meeting CR or PR measurement criteria (whichever occurs first) until the first date diseases progression. |
| Percentage of Participants With Overall Response Rate (ORR) | From date of randomization up to 44 weeks | The ORR was defined as percentage of participants who had a response of partial response (PR) or complete response (CR). The PR was achieved when a participant had at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The CR was achieved in a participant when all target lesions disappeared. Any pathological lymph nodes (whether target or non target) must have reduction in the short axis to \<10 millimeter (mm). |
| Percentage of Participants With Disease Control Rate (DCR) | From date of the first study treatment up to 44 weeks | The DCR was defined as percentage of participants who have a response of CR, PR, and stable disease (SD) \>= 16 weeks, DCR = CR + PR+ SD. The PR was achieved when a participant had at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The CR was achieved in a participant when all target lesions disappeared. Any pathological lymph nodes (whether target or non-target) must have reduction in the short axis to \<10mm. The SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). |
| Progression-free Survival (PFS) | From the date of first study treatment until the first date of PD, or death due (up to 44 weeks) | The PFS was defined as the duration of time from date of the first study treatment until the first date that PD is objectively documented or death due to any cause. The PD is defined as at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded since the treatment started. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. Appearance of one or more new lesions will also constitute PD. |
| Overall Survival (OS) | From date of the first study treatment until death (up to 44 weeks) | The OS was defined as the duration of time from date of the first study treatment until death from any cause. |
| Time to Progression (TTP) | From date of the first study treatment until the first date of PD or death (up to 44 weeks) | The TTP was defined as the duration of time from date of the first study treatment until the first date that PD was objectively documented or death due to PD. |
| Maximum Tolerated Dose (MTD) for KPT-9274 | From start of study drug administration up to 44 weeks | The MTD was defined as the highest dose at which less than or equal to (\<=) 1 participant experienced a dose limiting toxicity (DLT) in Cycle 1. A DLT was defined as an adverse event (AE) or abnormal laboratory value occurring within the first 28 days of treatment of KPT-9274, excluding those clearly caused by underlying disease, disease progression, or external factors. |
| Number of Dose Limiting Toxicities (DLT) Experienced by Participants | At Cycle 1 only (28-day cycle) | A DLT was defined as an AE or abnormal laboratory value occurring within the first 28 days of KPT-9274 treatment, excluding those clearly caused by underlying disease, disease progression, or extraneous causes, and meets any of the criteria for defining dose limiting toxicities. |
| Number of Participants With Adverse Event (AE) of Severity Grade >= 3 or 4, Serious AEs, and AEs Leading to Treatment Discontinuation | From start of study drug administration up to 49 weeks | The AE severity was graded on a scale from 1 to 4 using the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.03; any events not specifically listed in the scale were defined as: Grade 1 is mild; Grade 2 is moderate; Grade 3 is severe or medically significant; Grade 4 is life-threatening. An SAE was any untoward medical occurrence that at any dose met one, more of the following criteria: results in death, life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent, significant disability/incapacity, a congenital abnormality/birth defect, an important medical event. The AE leading to treatment discontinuation in the study. |

| Measure | Time frame | Description |
|---|---|---|
| Time-to-peak Plasma Concentration (Tmax) in Participants Who Received KPT-9274 | Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days) | Time taken by KPT-9274 to achieve maximum plasma concentration after the first dose administration. |
| Terminal Half-life (T1/2) in Participants Who Received KPT-9274 | Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days) | The T1/2 was defied as the time it takes for the concentration of KPT-9274 in the plasma to be reduced by 50%. |
| Volume of Distribution (Vd/F) in Participants Who Received KPT-9274 | Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days) | The Vd/F was defined as MRT\*CL/F, where MRT is the mean residence time (calculated as AUMC\[0-tau\]/AUC\[0-tau\], where AUMC\[0-tau\] is the area under the first moment curve determined as the area under the concentration\*time versus time curve). |
| Apparent Plasma Clearance (CL/F) in Participants Who Received KPT-9274 | Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days) | The CL/F was calculated as the KPT-9274 dose administered divided by the area-under-the-curve of KPT-9274 plasma concentration versus (vs) time. |
| Maximum Plasma Concentration (Cmax) in Participants Who Received KPT-9274 | Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days) | Cmax achieved by the KPT-9274 after the first dose administrations. |

Overall Survival (OS)
The OS was defined as the duration of time from date of the first study treatment until death from any cause.
Time frame: From date of the first study treatment until death (up to 44 weeks)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Percentage of Participants With Disease Control Rate (DCR)
The DCR was defined as percentage of participants who have a response of CR, PR, and stable disease (SD) \>= 16 weeks, DCR = CR + PR+ SD. The PR was achieved when a participant had at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The CR was achieved in a participant when all target lesions disappeared. Any pathological lymph nodes (whether target or non-target) must have reduction in the short axis to \<10mm. The SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD).
Time frame: From date of the first study treatment up to 44 weeks
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Percentage of Participants With Overall Response Rate (ORR)
The ORR was defined as percentage of participants who had a response of partial response (PR) or complete response (CR). The PR was achieved when a participant had at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The CR was achieved in a participant when all target lesions disappeared. Any pathological lymph nodes (whether target or non target) must have reduction in the short axis to \<10 millimeter (mm).
Time frame: From date of randomization up to 44 weeks
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Progression-free Survival (PFS)
The PFS was defined as the duration of time from date of the first study treatment until the first date that PD is objectively documented or death due to any cause. The PD is defined as at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded since the treatment started. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. Appearance of one or more new lesions will also constitute PD.
Time frame: From the date of first study treatment until the first date of PD, or death due (up to 44 weeks)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Time to Progression (TTP)
The TTP was defined as the duration of time from date of the first study treatment until the first date that PD was objectively documented or death due to PD.
Time frame: From date of the first study treatment until the first date of PD or death (up to 44 weeks)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Apparent Plasma Clearance (CL/F) in Participants Who Received KPT-9274
The CL/F was calculated as the KPT-9274 dose administered divided by the area-under-the-curve of KPT-9274 plasma concentration versus (vs) time.
Time frame: Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Maximum Plasma Concentration (Cmax) in Participants Who Received KPT-9274
Cmax achieved by the KPT-9274 after the first dose administrations.
Time frame: Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Terminal Half-life (T1/2) in Participants Who Received KPT-9274
The T1/2 was defied as the time it takes for the concentration of KPT-9274 in the plasma to be reduced by 50%.
Time frame: Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Time-to-peak Plasma Concentration (Tmax) in Participants Who Received KPT-9274
Time taken by KPT-9274 to achieve maximum plasma concentration after the first dose administration.
Time frame: Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
Volume of Distribution (Vd/F) in Participants Who Received KPT-9274
The Vd/F was defined as MRT\*CL/F, where MRT is the mean residence time (calculated as AUMC\[0-tau\]/AUC\[0-tau\], where AUMC\[0-tau\] is the area under the first moment curve determined as the area under the concentration\*time versus time curve).
Time frame: Cycle 1 and 2: Pre-dose, 3, 6, 8, 24, and 48 hours post-dose (each cycle =28 days)
Population: Study was terminated prematurely due to a lack of efficacy during primary analysis stage. Data for this outcome measure was not collected or analyzed as per planned analysis.
