About this study
This phase I/II trial studies the side effects and best dose of sapanisertib when given together with cabozantinib, and to see how well they work in treating patients with liver cancer that has spread from where it first started to other places in the body (metastatic) and contains a mutation (change) in the β-catenin gene. Sapanisertib and cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving sapanisertib and cabozantinib together may work better than giving cabozantinib alone in treating β-catenin-mutated metastatic hepatocellular carcinoma.

You may qualify if…
- ✓ Patients must have histologically or cytologically confirmed HCC, not amenable to curative treatment approach
- ✓ For Phase 2, patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥ 20 mm (≥ 2 cm) by chest x-ray or as ≥ 10 mm (≥ 1 cm) with CT scan, MRI, or calipers by clinical exam
- ✓ For phase 2, patients must have a β-catenin mutation, based on next generation eequencing (NGS) testing through Clinical Laboratory Improvement Amendments (CLIA)-certified commercially available standard of care assay
- ✓ Patients must have received at least one prior line of systemic therapy in the metastatic setting, including a prior immune checkpoint inhibitor therapy unless not eligible. For the phase 2 portion, patients must have received at least one and no more than two prior lines of systemic therapy in the metastatic setting, including a prior immune checkpoint inhibitor therapy unless not eligible
- ✓ Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of sapanisertib in combination with cabozantinib in patients \<18 years of age, children are excluded from this study
- ✓ Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 50%)
- ✓ Child Pugh score of A
- ✓ Absolute neutrophil count ≥ 1,000/mcL
You may not qualify if…
- ✕ Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia
- ✕ Patients who are receiving any other investigational agents
- ✕ History of allergic reactions attributed to compounds of similar chemical or biologic composition to sapanisertib and cabozantinib
- ✕ Use of strong CYP3A4-inhibiting agents due to drug-drug interaction with cabozantinib
- ✕ Prior exposure to cabozantinib
- ✕ Patients who are unable to swallow oral medications such as capsules and tablets and patients with gastrointestinal conditions that may affect the absorption of oral medications
- ✕ Patients with uncontrolled intercurrent illness or any other significant condition(s) that would make participation in this protocol unreasonably hazardous
- ✕ Pregnant women are excluded from this study because sapanisertib and cabozantinib have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with sapanisertib and cabozantinib, breastfeeding should be discontinued if the mother is treated with sapanisertib and cabozantinib
