Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Experimental: NKTR-102 - In Group A, NKTR-102 will be administered at a dose level of 145 mg/m2 on a q21d schedule as a 90-minute intravenous (IV) infusion on Day 1 of each treatment cycle.

Active comparator: Treatment of Physician's Choice (TPC) - In Group B, TPC will be administered per standard of care. Patients randomized to TPC will receive single-agent IV chemotherapy, limited to choice of one of the following 7 agents: eribulin, ixabepilone, vinorelbine, gemcitabine, paclitaxel, docetaxel, or nab-paclitaxel.

Eligibility
Key inclusion criteria
* Female or male, age = 18 years.
* Histologically-confirmed carcinoma of the breast (either the primary or metastatic lesions) for whom single-agent cytotoxic chemotherapy is indicated. Patients may have either measurable or non-measurable disease according to RECIST version 1.1.
* Patients must have a history of brain metastases that are non-progressing.
* For triple-negative breast cancer, a minimum of 1 prior cytotoxic chemotherapy regimen must have been administered for the indication of metastatic disease.Depending on receptor status, 1 or 2 prior cytotoxic regimens are required prior to enrollment in this trial; hormonal and/or human epidermal growth factor receptor 2 (HER2) -targeted agents may be required.
* Have had prior therapy (administered in the neoadjuvant, adjuvant, and/or metastatic setting) with an anthracycline, a taxane, and capecitabine (prior anthracycline can be omitted if not medically appropriate or contraindicated for the patient).
* Last dose of anticancer therapy must have been administered within 6 months of the date of randomization into this study.
* All anticancer- and radiation therapy-related toxicities must be completely resolved or downgraded to Grade 1 or less (neuropathy may be Grade 2 or less).
* Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
* Demonstrate adequate organ function obtained within 14 days prior to randomization and analyzed by the central laboratory.
* Women of childbearing potential (WCBP) must agree to use highly effective methods of birth control throughout the duration of the study until 6 months following the last dose of study drug.
* Males with female partners of child-bearing potential must agree to use a barrier contraception (e.g., condom with spermicidal foam/gel/film/cream/suppository) throughout the duration of the study until 6 months following the last dose of study drug; in addition to their female partner using either an intrauterine device or hormonal contraception and continuing until 6 months following the last dose of study drug. Male patients should not donate sperm until 6 months following the last dose of study drug.
