Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With Objective Response (OR) Participants with OR based on a assessment of confirmed complete remission (CR) or partial remission (PR) according to Cheson criteria for Acute myeloid leukemia (AML) and Myelodysplastic syndrome (MDS). CR: those with > 20% cellularity of bone marrow biopsy, no presence of extramedullary leukemia for AML, <5 % myeloblast cells for bone marrow with peripheral blood value lasting at least 1 month and 2 months for AML and MDS respectively. PR : those with all criteria for CR except 5-25 % blasts in bone marrow and at least 50% decrease in blast over pretreatment for AML and MDS respectively. Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 4 weeks up to 35 weeks No
Secondary Percentage of Participants With Hematologic Improvement (HI) HI was described by the number of individual and positively affected cell lines (Erythroid response, Platelet response, Neutrophil response). Improvements must last at least 2 months. Baseline, Week 2 thereafter every 4 weeks up to 35 weeks and follow up (at least 30 days after last dose) No
Secondary Duration of Response (DR) Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cause. 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. First documentation of objective response until objective disease progression or discontinuation from the study due to any cause assessed every 4 weeks up to 35 weeks No
Secondary Bone Marrow Micro Vessel Density (MVD) Bone marrow MVD in tumors is a measure of angiogenesis and a prognostic indicator that correlates with an increased risk of metastasis in various cancers and with overall and relapse free survival in participants with AML or MDS. Bone marrow biopsies and bone marrow clot samples were assessed for MVD (cluster of differentiation 31 [CD31] staining). Day 1, Week 2 thereafter every 4 weeks up to 35 weeks No
Secondary Vascular Endothelial Growth Factor Receptor 1 (VEGFR-1) and VEFGR Receptor 2 (VEGFR-2) Phosphorylation Vascular endothelial growth factor (VEGF) promotes cancer progression by inducing angiogenesis via VEGF receptors, signals directly through receptors VEGFR-1 and VEGFR-2. Change in biomarkers related to VEGFR signal transduction pathways after axitinib treatment was assessed. Mononuclear (MNC) cell VEGF receptor expression and phosphorylation was assessed by in situ western blot analysis. VEGFR-1 and VEGFR-2 evaluations were performed using samples from peripheral blood plasma, bone marrow aspirate, bone marrow (Core) biopsy and bone marrow clot. Day 1, Week 2 thereafter every 4 weeks up to 35 weeks and follow up (at least 30 days after last dose) No
Secondary Plasma Vascular Endothelial Growth Factor (VEGF) Concentration VEGF promotes cancer progression by inducing angiogenesis via VEGF receptors, signals directly through receptors VEGFR-1 and VEGFR-2. Change in biomarkers related to VEGFR signal transduction pathways after axitinib treatment was assessed. Plasma VEGF concentration evaluations were performed using samples from peripheral blood plasma, bone marrow aspirate, bone marrow (Core) biopsy and bone marrow clot. Day 1, Week 2 thereafter every 4 weeks up to 35 weeks and follow up (at least 30 days after last dose) No
Secondary Population Pharmacokinetics of Axitinib (AG-013736) 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. Day 1 (pre-dose) and every 4 weeks up to 35 weeks No
Secondary Overall Survival (OS) 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 adverse event 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. Baseline to death due to any cause or at least every 3 months after discontinuation of study treatment No
