This is a single arm, compassionate use study with 30 patients for leronlimab (PRO 140) combined with a treatment of physician's choice (TPC) in patients with CCR5+ mTNBC.~Leronlimab (PRO 140) will be administered subcutaneously as weekly dose of 350 mg until disease progression or intolerable toxicity. Treatment of Physician's Choice (TPC) is defined as one of the following single-agent chemotherapy drugs administrated according to local practice: eribulin, gemcitabine, capecitabine, paclitaxel, nab-paclitaxel, vinorelbine, ixabepilone, or carboplatin. The selected treatment should be administered as per the dosing schedule included on the package insert.~In this study, patients will be evaluated for tumor response approximately every 3 months or according to institution's standard practice by CT, PET/CT or MRI with contrast (per treating investigator's discretion) using the same method as at baseline. Tumor measurements will be done using RECIST v1.1.
