Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Objective Response (OR) | Baseline to disease progression or discontinuation from study due to any cause, assessed every 8 weeks up to 152 weeks | Percentage of participants with OR based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of responses. CR are defined as the disappearance of all lesions (target and/or non target). PR are those with at least 30 percent (%) decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum of longest dimensions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DR) | Baseline to disease progression or discontinuation from study due to any cause, assessed every 8 weeks up to 152 weeks | Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cancer. Duration of tumor response was calculated as the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1. DR was calculated for the subgroup of participants with a confirmed objective tumor response. |
| Progression-free Survival (PFS) | Baseline until the date of first documented progression or death due to any cause, assessed every 8 weeks up to 152 weeks | Time in days from start of study treatment to first documentation of objective tumor progression or death due to any cause. PFS was calculated as first event date minus the date of first dose of study medication plus 1. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease \[PD\]), or from adverse event (AE) data (where the outcome was Death). |
| Overall Survival (OS) | Baseline to death due to any cause or at least 1 year after the first dose for the last participant | Time in days from the start of study treatment to date of death due to any cause. OS was calculated as the death date minus the date of first dose of study medication plus 1. Death was determined from AE data (where outcome was death) or from follow-up contact data (where the participant current status was death). For participants who were alive, overall survival was censored at the last contact. |
| Functional Assessment of Cancer Therapy (FACT)-Kidney Symptom Index for Disease Cancer Related Symptoms (FKSI-DRS) Score | Baseline (Day 1 of Cycle 1), Day 1 of all subsequent cycles up to Cycle 38 and follow up (28 days after last dose) | FKSI-DRS is a subset of FKSI which is a questionnaire for FACT -Kidney Symptom Index used to assess Quality of Life (QoL)/participant-reported outcomes for participants diagnosed with renal cell cancer. The FKSI contained 15 questions and the FKSI-DRS consisted of 9 questions each ranging from 0 (not at all) to 4 (very much) so that FKSI-DRS ranged between 0-36. Since the questions could be reversed coded, as appropriate, before calculating FKSI-DRS, 0 and 36 could be considered the worst and best health states based on the 9 questions comprising FKSI-DRS. |
| Population Pharmacokinetics of Axitinib (AG-013736) | Day 1 (Pre-dose), Day 29, Day 57 and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks | Data for this outcome measure are not reported here because the analysis population includes participants who were not enrolled in this study. ClinicalTrials.gov is designed for reporting results from only those participants who were enrolled in the study and described in the Participant Flow and Baseline Characteristics modules. |

| Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Progression-free Survival (PFS) | Day 1 (Pre-dose), Day 29, and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks | AUCss is a pharmacokinetic parameter derived from plasma concentration versus time data using non-compartmental or population based analysis methods. PFS is median time from first dose of study treatment to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first. Relationship of PFS versus AUCss was determined as median PFS in participants with high AUCss \[AUCss greater than or equal to (\>=) median AUCss\] or low AUCss \[AUCss less than (\<) median AUCss\]. |
| Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Overall Survival (OS) | Day 1 (Pre-dose), Day 29 and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks | AUCss is a pharmacokinetic parameter derived from plasma concentration versus time data using non-compartmental or population based analysis methods. OS is time in weeks from the start of study treatment to date of death due to any cause. Relationship of OS versus AUCss was determined as median OS in participants with high AUCss \[AUCss \>= median AUCss\] or low AUCss \[AUCss \< median AUCss\]. |
| Correlation of Area Under the Concentration-time Curve at Steady State (AUCss) With Confirmed Partial Response (PR) | Day 1 (Pre-dose), Day 29 and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks | AUCss: pharmacokinetic parameter derived from plasma concentration versus time data using non-compartmental or population based analysis methods, computed as each participant's average total daily dose (accounting for dose reductions and any recorded missed doses) divided by population estimated posthoc individual apparent clearance (CL/F), i.e., AUCss = Daily Dose/(CL/F), where F refers to the oral bioavailability, and CL refers to the systemic clearance. PR: responses with at least 30% decrease in sum of longest dimensions of target lesions using baseline (pre-treatment) sum of longest dimensions as reference. Logistic regression with general linear model was applied to data of PR using AUCss; PR was correlated with AUCss as fold increase in odds of PR with increase in AUCss. Fold increase was calculated as exponent of product of logistic regression slope coefficient and unit change of AUCss. |
| Functional Assessment of Cancer Therapy (FACT)-Kidney Symptom Index (FKSI) Score | Baseline (Day 1 of Cycle 1), Day 1 of all subsequent cycles up to Cycle 38 and follow up (28 days after last dose) | FKSI is a questionnaire for FACT-Kidney Symptom Index used to assess QoL/participant-reported outcomes for participants diagnosed with renal cell cancer. The FKSI contained 15 questions each ranging from 0 (not at all) to 4 (very much) so that FKSI ranged between 0-60 where higher scores reflects better functioning and fewer symptoms. |

OS is time in weeks from the start of study treatment to date of death due to any cause. Relationship of OS versus AUCss was determined as median OS in participants with high AUCss \[AUCss \>= median AUCss\] or low AUCss \[AUCss \< median AUCss\].
Time frame: Day 1 (Pre-dose), Day 29 and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks
Population: Participants for whom both PK and OS data were available were included in analysis. 'n' signifies number of participants evaluable for the corresponding category.
| Arm | Measure | Group | Value (MEDIAN) |
|---|---|---|---|
| Axitinib | Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Overall Survival (OS) | OS at Low AUCss: Cycle1 (n=28) | 43 weeks |
| Axitinib | Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Overall Survival (OS) | OS at High AUCss: Cycle1 (n=29) | 88 weeks |
Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Progression-free Survival (PFS)
AUCss is a pharmacokinetic parameter derived from plasma concentration versus time data using non-compartmental or population based analysis methods. PFS is median time from first dose of study treatment to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first. Relationship of PFS versus AUCss was determined as median PFS in participants with high AUCss \[AUCss greater than or equal to (\>=) median AUCss\] or low AUCss \[AUCss less than (\<) median AUCss\].
Time frame: Day 1 (Pre-dose), Day 29, and then every 8 weeks until disease progression or discontinuation from study or up to 152 weeks
Population: Participants for whom both PK and PFS data were available were included in analysis. 'n' signifies number of participants evaluable for the corresponding category.
| Arm | Measure | Group | Value (MEDIAN) |
|---|---|---|---|
| Axitinib | Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Progression-free Survival (PFS) | PFS at Low AUCss: Cycle1 (n=28) | 31 weeks |
| Axitinib | Relationship of Area Under the Concentration-time Curve at Steady State (AUCss) With Progression-free Survival (PFS) | PFS at High AUCss: Cycle1 (n=29) | 39 weeks |
