Clinical Trial Summary

This is an open label, three-arm, phase 1 dose escalation study and phase 2 study of BBI608 in combination with sorafenib, or BBI503 in combination with sorafenib. The study population is adult patients with advanced hepatocellular carcinoma who have not received systemic chemotherapy.

Description:

This is an open label, three-arm, phase 1 dose escalation study and phase 2 study of BBI608 in combination with sorafenib, or BBI503 in combination with sorafenib. The study population is adult patients with advanced hepatocellular carcinoma (HCC) who have not received systemic chemotherapy.

The phase 1 portion will involve dose-escalation of BBI608 administered in combination with a fixed starting dose of sorafenib (Arm 1), and dose escalation of BBI503 administered in combination with a fixed starting dose of sorafenib (Arm 2). The fixed starting dose-level of sorafenib for both arms will be 400 mg twice daily (800 mg total daily dose). Eligible patients will be randomized to either Arm 1 or Arm 2.

The phase 2 portion will be an open-label, 3-arm, randomized trial of patients with advanced HCC who have not received prior systemic treatment. Patients will be randomized to receive either, Arm 1: sorafenib administered in combination with BBI608 (at the RP2D determined for BBI608 plus sorafenib during the phase 1 portion); Arm 2: sorafenib in combination with BBI503 (at the RP2D determined for BBI503 plus sorafenib during the phase 1 portion), or Arm 3: sorafenib alone at a starting dose of 400 mg twice daily. The starting dose for sorafenib is the same for all study arms.

11. Subjects with a history of another primary cancer, with the exception of: a) curatively resected non-melanoma skin cancer; b) curatively treated cervical carcinoma in situ; or c) other primary solid tumor with no known active disease present that, in the opinion of the investigator, will not affect patient outcome in the setting of current hepatocellular carcinoma diagnosis.

12. Abnormal ECGs which are clinically significant such as QT prolongation (QTc > 480 msec), clinically significant cardiac enlargement or hypertrophy, new bundle branch block, or signs of active ischemia. Patients with evidence of prior infarction who are New York Heart Association (NYHA) functional classes II, III, or IV are excluded, as are patients with marked arrhythmias such as Wolff Parkinson White pattern or complete atrioventricular (AV) dissociation.
