This is a phase 2 multicenter, double-blind, randomized, placebo-controlled, two-arm study for subjects with locally recurrent or metastatic triple negative breast cancer.
This is a phase 2 multicenter, double-blind, randomized, placebo-controlled, two-arm study for subjects with locally recurrent or metastatic triple negative breast cancer. Patients will be randomized 2:1 to either tivozanib hydrochloride and weekly paclitaxel or placebo and weekly paclitaxel. Subjects will be stratified based on Eastern Cooperative Oncology Group (ECOG) performance score (0 vs 1) and line of treatment (first vs second). All subjects will be evaluated for progression free survival and overall survival as well as safety and tolerability. Biomarker and pharmacokinetic (PK) analysis are also included in study. This study will determine whether tivozanib hydrocholoride combined with weekly paclitaxel improves clinical outcomes in patients with triple negative breast cancer.

Comparison of Progression-free Survival (PFS) of Subjects
PFS is defined as the time from randomization to progressive disease (PD) or death. The PFS comparison was performed for subjects treated with tivozanib hydrochloride in combination with paclitaxel vs placebo in combination with paclitaxel.
Time frame: approximately 24 months
Comparison of Objective Response Rate (ORR) and Duration of Response (DoR) of Subjects
ORR is defined as the proportion of patients with tumor size reduction of a predefined amount and for a minimum time period. DoR is defined as the length of time that a tumor continues to respond to treatment without the cancer growing or spreading. The ORR and DoR comparison was performed for subjects treated with tivozanib hydrochloride in combination with paclitaxel vs placebo in combination with paclitaxel.
Time frame: approximately 24 months
Comparison of Overall Survival (OS) of Subjects
OS measures how long subjects, who undergo a certain treatment regimen, live compared to subjects who are in a control group (i.e., taking either another drug or an inactive treatment, known as a placebo). OS comparison was performed for subjects treated with tivozanib hydrochloride in combination with paclitaxel vs placebo in combination with paclitaxel.
Time frame: approximately 24 months
Safety and Tolerability of Tivozanib Hydrochloride in Combination With Paclitaxel vs Placebo in Combination With Paclitaxel
Number of subjects with serious and non-serious adverse events.
Time frame: approximately 24 months
Pharmacokinetics (PK) of Tivozanib Hydrochloride and Paclitaxel When Administered in Combination
PK is defined as the study of the bodily absorption, distribution, metabolism, and excretion of drugs.

Identification of Hypoxia Gene Signature
Evaluation of hypoxia gene signature as a predictive biomarker of tivozanib hydrochloride response and establish the optimal cut-off to identify biomarker positive and negative subgroups. The genes comprising the hypoxia gene signature was analyzed in tumor tissue from subjects.
Time frame: Cycle 1, Day 1: Pre-dose and 2, 4 and 24 hours post dose; Cycle 1, Day 8: Pre-dose; Cycle 1, Day 21: Pre-dose and 2, 4, 24, 48, and 96 hours post dose; Cycle 2 (Day 1): Pre-dose
Measurement of Subjects' Quality of Life (QoL)
The Functional Assessment of Cancer Therapy-Breast (FACT-B) and Euro Quality of Life - 5 Dimensions (EQ-5D) questionnaires was used throughout the study to measure subjects' health-related QoL.
Time frame: approximately 24 months
