Detailed Description

This is a standard Phase 1b and 2a, multi-center, study design that will examine the safety, tolerability, maximum tolerated dose, and overall response rate of tivozanib (AV-951) and paclitaxel in a breast cancer.

In the Phase 1b study, only the doses of tivozanib (AV-951) will be escalated from 0.5 mg/day to 1.5 mg /day. All subjects will receive doses of weekly paclitaxel chemotherapy.

The Phase 2a study portion of the study was not conducted.

Conditions

Metastatic Breast Cancer

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

tivozanib (AV-951) + paclitaxel

Group Type: EXPERIMENTAL

tivozanib (AV-951) + paclitaxel

Intervention Type: DRUG

Tivozanib (AV-951):

Subjects in the Phase 1b study will receive 1 dose of tivozanib (AV-951) on Day -5 (± 2 days) for PK sampling prior to Cycle 1 only.

Thereafter in the Phase 1b and 2a study, subjects will receive tivozanib (AV-951) once daily for 3 weeks beginning on Day 1, followed by 1 week off treatment (1 cycle = 4 weeks). On days when paclitaxel and tivozanib (AV-951) are co-administered, AV-951 will be administered immediately following the end of the paclitaxel infusion.

Paclitaxel: Phase 1b study and Phase 2a study:

All subjects will receive IV paclitaxel 90 mg/m2, administered over 1 hour once a week for 3 weeks, followed by 1 week off (1 cycle = 4 weeks).

• Chemotherapy (at least 6 weeks for nitrosoureas, mitomycin C, and liposomal doxorubicin)
• Other signal transduction inhibitors and monoclonal antibodies
• Immunotherapy or biological response modifiers
• Any experimental therapy

9. No treatment with radiotherapy within 2 weeks (if involving < 25% of bone marrow), or 4 weeks (if involving ≥ 25% of bone marrow) prior to start of protocol therapy.

19. Full dose oral anticoagulation with warfarin, acenocoumarol, fenprocoumon, or similar agents. If previously receiving these type of agents, a minimum washout of 1 week and documented INR < 1.5 x ULN will be required prior to start of protocol therapy.
