  • Phase 1 patients (breast or ovarian cancer)
  • Patients with advanced or metastatic breast cancer must have disease that is HER2-negative, estrogen receptor-negative, and progesterone receptor-negative (ie, TNBC). Patients with advanced or metastatic disease may have up to 4 lines of cytotoxic therapy. Neoadjuvant and adjuvant therapies are not counted towards lines of therapy.
  • Patients must have any epithelial (ie, serous, endometroid, mucinous, clear cell) ovarian, fallopian tube, or primary peritoneal cancer. Patients must have experienced a response lasting at least 6 months to first-line platinum-based therapy but currently considered to have platinum-resistant disease per investigator's assessment (e.g, patient is not eligible for further platinum containing treatment). Patients may have received up to 5 lines of cytotoxic therapy for advanced or metastatic cancer. Neoadjuvant and adjuvant therapies are not counted towards lines of therapy.
  • Phase 2 patients (breast or ovarian cancer)
  • Patients with advanced or metastatic breast cancer must have TNBC. Patients with advanced or metastatic disease may have received up to 2 lines of cytotoxic therapy. Adjuvant and/or neoadjuvant therapies are not counted in the number of lines of therapy. TNBC patients who have previously received platinum chemotherapy in the metastatic setting are allowed to enroll in the study as long as they did not progress while on or within 8 weeks from the day of the last platinum administration.
  • Patients must have with high-grade serous or endometroid ovarian, fallopian tube, or primary peritoneal cancer. Patients must have experienced a response lasting at least 6 months to first-line platinum-based therapy but currently considered to have platinum-resistant disease per investigator's assessment (e.g, patient is not eligible for further platinum containing treatment). Patients may have had up to 4 lines of cytotoxic therapy for advanced or metastatic cancer. Neoadjuvant, adjuvant, and the combination of both will be considered as one line of therapy.

    PFS is defined as the time from first dose of study treatment to the earlier date of assessment of progression or death by any cause in the absence of progression based on the time of first documentation of disease progression per RECIST v1.1. Progression is defined using RECIST v1.1 as a 20% increase in the sum of the diameter of target lesions or unequivocal progression of existing non-target lesions or the appearance of one or more new lesions.

  9. Phase 2: PFS as Measured by irRECIST
