Study of Sacituzumab Govitecan in Participants With Metastatic Solid Tumors

Open to people ages 18 years and up

• Individuals with the following histologically documented metastatic (M1, Stage IV) or locally advanced solid tumors
  • NSCLC (adenocarcinoma or SCC) that has progressed after prior platinum-based chemotherapy and programmed death-(ligand) 1 (PD-(L)1) directed therapy
  • HNSCC that has progressed after prior platinum-based chemotherapy and anti-PD-(L)1 directed therapy No more than 3 prior lines of systemic treatment is allowed
  • Endometrial carcinoma that has progressed after prior platinum-based chemotherapy and anti-PD-(L)1 directed therapy No more than 3 prior lines of systemic treatment is allowed.
  • Extensive stage SCLC that has progressed after prior platinum-based chemotherapy and PD-(L)1 directed therapy. No more than one prior line of systemic treatment is allowed (re-challenge with the same initial regimen is not allowed)
• Eastern Cooperative Oncology Group (ECOG) Performance status score of 0 or 1
• Adequate hematologic counts without transfusional or growth factor support within 2 weeks of study drug initiation
• Adequate hepatic and renal function (CrCl ≥30mL/min)
• Individual 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

• Have had a prior anti-cancer biologic agent within 4 weeks prior to study Day 1 or have had prior chemotherapy, targeted small molecule therapy, 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. Individuals 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 individuals with carcinomatous meningitis are excluded regardless of clinical stability

• Additional cohort specific exclusion criteria
