Brief summary
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.
Detailed description
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 Overall Survival (OS) of Subjects | approximately 24 months | 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. |

| Comparison of Objective Response Rate (ORR) and Duration of Response (DoR) of Subjects | approximately 24 months | 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. |

The genes comprising the hypoxia gene signature was analyzed in tumor tissue from subjects. |
| Measurement of Subjects' Quality of Life (QoL) | approximately 24 months | 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. |
| Pharmacokinetics (PK) of Tivozanib Hydrochloride and Paclitaxel When Administered in Combination | approximately 24 months | PK is defined as the study of the bodily absorption, distribution, metabolism, and excretion of drugs. |

Recruitment details
Participants who met all the inclusion and none of the exclusion criteria were enrolled
Pre-assignment details
All participants underwent inclusion and exclusion criteria assessment and all eligible subjects signed the informed consent before undergoing any study related procedures. The study was terminated prior to completing enrollment, hence descriptive statistical analyses were performed for a limited set of data.
