Brief Summary:
This is a phase Ib/II Study of Leronlimab (PRO 140) combined with Carboplatin in Patients with CCR5+ Metastatic Triple Negative Breast Cancer (mTNBC).
Study population will consist of patients with CCR5-positive, locally advanced or metastatic triple-negative breast cancer (mTNBC) who are naïve to chemotherapy in metastatic setting but have been exposed to anthracyclines and taxane in neoadjuvant and adjuvant settings (first-line).

Detailed Description:
Phase Ib
Phase Ib is a dose escalation phase with 3 dose levels (cohorts) of leronlimab (PRO 140) administered in combination with a fixed dose of carboplatin at AUC 5 (area under the curve). This dose finding portion of study will follow a "3+3" designed to determine the maximum tolerated dose (MTD) of leronlimab (PRO 140) administered as subcutaneous (SC) injection in subjects with histologically confirmed mTNBC that express CCR5.
Phase II
Phase II is a single arm study with 30 patients in order to test the hypothesis that the combination of carboplatin AUC 5 intravenously and MTD of leronlimab (PRO 140) SC will increase Progression Free Survival (PFS) in patients with CCR5 + mTNBC.
