Summary
The primary objective in Phase I is to evaluate the safety and tolerability of sacituzumab govitecan-hziy (SG) as a single agent administered in 21-day treatment cycles in previously treated participants with advanced epithelial cancer. In Phase II, the primary objective is to evaluate the safety and efficacy of sacituzumab govitecan-hziy administered in 21-day treatment cycles at a dose selected in Phase I.
Tumor types in the study will include: cervical, colorectal, endometrial, ovarian, esophageal, gastric adenocarcinoma, glioblastoma multiforme, head and neck cancers- squamous cell, hepatocellular, prostate, non-small-cell lung cancer, pancreatic, renal cell, small-cell lung cancer, non-triple negative breast cancer (non-TNBC), triple-negative breast cancer (TNBC) and metastatic urothelial cancer (mUC).
Eligibility Criteria
Inclusion Criteria
- Individuals able to understand and give written informed consent.
- Histologically or cytologically confirmed epithelial cancer of one of the following types:
- Gastric adenocarcinoma (GC)
- Esophageal cancer (EC)
- Hepatocellular carcinoma (HCC)
- Non-small-cell lung cancer (NSCLC)
- Small-cell lung cancer (SCLC)
- Epithelial ovarian cancer (EOC)
- Cervical Cancer
- Endometrial Cancer
- Triple-negative breast cancer (TNBC)
- Non-triple-negative breast cancer
- Papillary thyroid cancer (excludes follicular, medullary, Hurthle cell, and anaplastic thyroid cancer)
- Glioblastoma multiforme (GBM)
- Hormone-refractory prostate cancer (HRPC)
- Head and neck cancers- squamous cell (SCCHN)
- Renal cell cancer (clear cell) (RCC)
- Urothelial cancer
- Stage IV (metastatic) disease (except for individuals with GBM).
- Refractory to or relapsed after at least one prior standard therapeutic regimen
- Adequate performance status (ECOG 0 or 1)
- Expected survival ≥ 6 months.
- Measurable disease by CT or MRI.
- At least 2 weeks beyond treatment (chemotherapy, investigational drugs including small molecular inhibitors, immunotherapy and/or radiation therapy) or major surgery and recovered from all acute toxicities to Grade 1 or less (except alopecia).
- At least 2 weeks beyond high dose systemic corticosteroids (however, low dose corticosteroids 9 g/dL, absolute neutrophil count (ANC) > 1,500 per mm^3, platelets > 100,000 per mm^3).
- Adequate renal and hepatic function (creatinine ≤ 2.0 x institutional upper limit of normal (IULN), bilirubin ≤ 1.5 IULN, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0 x IULN or 5 x IULN if know liver metastases).
- Otherwise, all toxicity at study entry ≤ Grade 1.
Exclusion Criteria
- Women who are pregnant or lactating.
- Women of childbearing potential and fertile men unwilling to use effective contraception during study until conclusion of 12-week post-treatment evaluation period.
- Individuals with Gilbert's disease.
- Individuals with brain metastases can be enrolled only if treated, non-progressive brain metastases and off high-dose steroids (> 20 mg prednisone or equivalent) for at least 4 weeks.
- Presence of bulky disease (defined as any single mass > 7 cm in its greatest dimension). Individuals with a mass over 7 cm, but otherwise eligible, may be considered for enrollment after discussion and approval with the medical monitor.
- Individuals with active ≥ grade 2 anorexia, nausea or vomiting, and/or signs of intestinal obstruction.
- Individuals with non-melanoma skin cancer or carcinoma in situ of the cervix are eligible, while individuals with other prior malignancies must have had at least a 3-year disease-free interval.
- Individuals known to be HIV positive, hepatitis B positive, or hepatitis C positive.
- Known history of unstable angina, MI, or CHF present within 6 months or clinically significant cardiac arrhythmia (other than stable atrial fibrillation) requiring anti-arrhythmia therapy.
- Known history of clinically significant active COPD, or other moderate-to-severe chronic respiratory illness present within 6 months.
- Prior history of clinically significant bleeding, intestinal obstruction, or GI perforation within 6 months of initiation of study treatment.
- Infection requiring intravenous antibiotic use within 1 week.
- History of an anaphylactic reaction to irinotecan or ≥ Grade 3 GI toxicity to prior irinotecan,
- Other concurrent medical or psychiatric conditions that, in the Investigator's opinion, may be likely to confound study interpretation or prevent completion of study procedures and follow-up examinations.
