Trial Outcomes & Findings for Axitinib For The Treatment Of Advanced Hepatocellular Carcinoma (NCT NCT01210495)

Total 224 participants were enrolled in the study. Randomized portion enrolled 202 participants in 2 arms (134 in axitinib, 68 in placebo) in 70 centers (13 countries). Non-randomized portion enrolled 22 participants in 2 cohorts (15 in Child-Pugh Class A, 7 in Child-Pugh Class B score 7) according to Child-Pugh score in 13 centers (4 countries).

Participants with Child-Pugh Class A (score 5 or 6) could have been enrolled into either non-randomized or to randomized portion. Participants with Child-Pugh Class B (score 7) were initially enrolled into non-randomized portion but following determination of recommended axitinib starting dose they could have been enrolled in randomized portion.

Axitinib For The Treatment Of Advanced Hepatocellular Carcinoma

OS was defined as the time from the date of randomization to the date of death due to any cause. OS (in months) was calculated as (date of death - first randomization date +1)/30.4. For participants still alive at the time of the analysis, the OS time was censored on the last date they were known to be alive. All participants were followed up for survival at least every 3 months after discontinuing study treatment until at least two years after randomization of the last participant.

PFS was defined as time from randomization to first documented objective tumor progression or to death due to any cause, whichever occurred first. PFS (in months) was calculated as (first event date - first randomization date +1)/30.4. 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). As per response evaluation criteria in solid tumors (RECIST) 1.1, progression was defined as greater than or equal to (\>=) 20% increase in sum of longest dimensions of target lesions or appearance of one or more new target lesions and unequivocal progression of existing non-target lesions, or appearance of 1 new non-target lesions. Participants discontinuing study treatment without documented evidence of PD were to be followed up at least every 8 weeks after discontinuing study treatment until disease progression, or initiation of another anticancer treatment.

ORR was defined as the percentage of participants with confirmed complete response (CR) or confirmed partial response (PR) according to the RECIST 1.1. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must decrease to normal (short axis \<10 millimetres \[mm\]). PR was defined as a 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

TTP was defined as the time from randomization to first documentation of objective tumor progression. If tumor progression data included more than 1 date, the first date was used. TTP (in months) was calculated as (first event date - first randomization date +1)/30.4.

DR was defined as the time from the first documentation of objective tumor response (CR or PR) that was subsequently confirmed to the first documentation of PD or to death due to any cause, whichever occurs first. If tumor progression data included more than 1 date, the first date was to be used. DR (in months) was to be calculated as (the end date for DR - first CR or PR that was subsequently confirmed +1)/30.4.

CBR was defined as the percentage of participants with confirmed CR or confirmed PR or a best response of stable disease \>=8 weeks according to RECIST 1.1 criteria, relative to all randomized participants who had baseline measurable disease. Confirmed responses were defined as those that persisted on repeat imaging study \>=4 weeks after the initial documentation of response. Participants who did not have on study radiographic tumor re-evaluation or who died, progressed, or dropped out for any reason prior to reaching a CR, PR, or stable disease were counted as non-responders in the assessment of CBR. A participant who initially met the criteria for a PR and then subsequently became a confirmed CR was to be assigned a best response of CR.

Axitinib samples were to be collected from all participants on Cycle 1 Day 15 at the following time points: pre-dose, 1, 2, 3, 4, 6 and 8 hours after axitinib dosing.

Axitinib samples were to be collected from all participants on Cycle 1 Day 15 at the following time points: pre-dose, 1, 2, 3, 4, 6 and 8 hours after axitinib dosing. In the below table, 4 participants in Child-Pugh A and 1 participant in Child-Pugh B were not reported due to nonestimable half-life.

Plasma soluble proteins interleukin-6 (IL-6), E-Selectin, interleukin-8 (IL-8), hepatocyte growth factor (HGF), matrix metalloproteinase-2 (MMP-2), stem cell factor (SCF), angiopoietin-2 (Ang-2), vascular endothelial growth factor-A (VEGF-A), vascular endothelial growth factor-C (VEGF-C), soluble vascular endothelial growth factor receptor 2 (sVEGFR2), soluble vascular endothelial growth factor receptor 3 (sVEGFR3), stromal cell-derived factor-1 (SDF1), neutrophil gelatinase-associated lipocalin (NGAL), migration inhibitory factor (MIF), c-MET, regulated upon activation normal T cell expressed and presumably secreted (RANTES), and monocyte chemotactic protein-3 (MCP-3) were only measured in randomized participants.

A 5 millilitres (mL) whole blood sample was collected from all randomized participants to evaluate the miRNA transcripts.
