Summary

This is a multicenter, Phase I/II study in patients with non-resectable hepatocellular carcinoma following TACE treatment.

Phase I (Open-label dose escalation)

This study will be an open-label study with an Accelerated Phase and a Standard Phase. For the Accelerated Phase of the study, one patient per dose level (1 mg/kg, and 2 mg/kg) is planned. For the dose levels in the standard phase (4 mg/kg, 8 mg/kg and 16 mg/kg), it will follow the Fibonacci's rule of 3 + 3 design. All eligible patients who have received TACE treatment and recovered well, will be administrated PTX-9908 Injection intravenously one dose per day for 5 days on Week 1 (excludes weekends and public holidays), and one dose per week (on Day 8, Day 15, and Day 22) for 3 consecutive weeks. The 4-week treatment period, will be followed by a 2-week follow-up period.

Phase II (Randomized placebo controlled dose expansion)

The objective of phase II is to further evaluate the safety, tolerability and antitumor activity of PTX-9908 Injection for patients with non-resectable hepatocellular carcinoma following TACE treatment. Approximately 24 eligible patients who have received TACE treatment and recovered, will be randomized to PTX-9908 Injection using the predetermined dose in phase I or the vehicle placebo in a 2:1 ratio. PTX-9908 Injection or placebo will be administered intravenously one dose per day for 5 days in Week 1 (excludes weekends and public holidays), and one dose per week till Week 12 (Day 78). The 12-week treatment period, will be followed by a 2-week follow-up period.
