Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Breast Cancer | Metastasis
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

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.

Exclusion Criteria:

  • Last dose of anticancer therapy (including HER2-targeted therapy) within 14 days prior to randomization.
  • High-dose chemotherapy followed by stem cell transplantation (autologous or allogeneic).
  • Major surgery within 28 days prior to randomization.
  • Concomitant use of any anticancer therapy or use of any investigational agent(s).
  • Received prior treatment for cancer with a camptothecin-derived agent.
  • Lesions on imaging, by cerebrospinal fluid or with neurological findings that are consistent with leptomeningeal disease or meningeal carcinomatosis.
  • Chronic or acute GI disorders resulting in diarrhea of any severity grade.
  • Patients who are pregnant or lactating, plan to get pregnant, or have a positive serum pregnancy test prior to randomization.
  • Enzyme-inducing anti-epileptic drugs (EIAEDs) within 14 days of randomization.
  • Hepatitis B or C, tuberculosis, or HIV.
  • Cirrhosis.
  • Prior malignancy (other than breast cancer) unless diagnosed and definitively treated more than 5 years prior to randomization.
  • Daily use of oxygen supplementation.
  • Significant known cardiovascular impairment.
  • Prior treatment with NKTR-102.
  • Psychiatric illness, social situation, or geographical situation that preclude informed consent or limit compliance.
  • Known intolerance or hypersensitivity to any of the products used in this study or their excipients.
  • For patients selecting vinorelbine or gemcitabine as the TPC agent, patients may not receive yellow fever vaccine in the 28 days prior to randomization.
