Study of Sorafenib With or Without VT-122 in Patients With Hepatocellular Carcinoma (HCC)

Participants will be on sorafenib at least 30 days before randomization into either the Treatment or Control Arms. Sorafenib will be administered according to the package insert unless contraindicated based on physician expertise.

Participants randomized to the VT-122 regimen (sorafenib plus VT-122) will receive oral doses of propranolol and etodolac, which will be titrated over a period of 3 weeks until the participant reaches a maximum tolerated dose (MTD)\[no higher than 60 mg propranolol, twice daily (BID)/300 mg etodolac, BID\]. Once the individual MTD has been reached, participants will enter a Maintenance Treatment period, and will receive the VT-122 regimen (propranolol and etodolac, co administered orally) on a continuous BID dosing schedule for a maximum of twelve 4-week cycles.

Participants randomized to the Control Arm (sorafenib with placebo) will receive placebo for the same periods as participants randomized to the Treatment Arm. Participants in the Control Arm will undergo the same visits and mock dose escalation.
