Trial Purpose and Description

Eligibility Criteria

Inclusion Criteria:

  • Female or male subjects, >18 years of age, able to understand and give written informed consent.
  • Subjects with the following histologically documented metastatic (M1, Stage IV) or locally advanced solid tumors. NSCLC (adenocarcinoma or SCC), that has progressed after one line of platinum-based chemotherapy and PD-L1 or PD-1 directed therapy; recurrence/ relapse or lack of response within 6 months of completion of chemotherapy for locally advanced disease, that line of therapy may be counted for eligibility. Relapsed unresectable endometrial cancer that has progressed after prior platinum-based chemotherapy or is refractory to platinum-based chemotherapy.
  • Eastern Cooperative Oncology Group (ECOG) Performance status score of 0 or 1 (see Appendix 1)
  • Adequate hematologic counts without transfusional or growth factor support within 2 weeks of study drug initiation
  • Adequate hepatic function
  • Subject must have at least a 3-month life expectancy.
  • Have measurable disease by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria (see Appendix 4). Tumor lesions situated in a previously irradiated area may be utilized if they are considered measurable and progression has been demonstrated in such lesions.

Exclusion Criteria:

  • Hepatitis B/C
  • Has had a prior anti-cancer biologic agent within 4 weeks prior to study Day 1 or have had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1.
  • Have not recovered (i.e., ≤ Grade 1) from adverse events due to a previously administered agent
  • Have previously received topoisomerase I inhibitors
  • Have an active second malignancy
  • Have known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they have stable CNS disease for at least 4 weeks prior to the first dose of study drug and all neurologic symptoms have returned to baseline, have no evidence of new or enlarging brain metastases and are taking ≤20 mg/day of prednisone or its equivalent. All subjects with carcinomatous meningitis are excluded regardless of clinical stability
