Brief summary
The main purpose of this trial is to evaluate the safety of the new adjuvant treatment of curative HCC, or the treatment of long-acting interferon P1101 alone, or the use of long-acting interferon P1101 and subsequent treatment of anti-PD1, and any efficacy in reducing the recurrence rate of patients after surgery.
Detailed description
secondary end-point: P1101 and anti-PD1 sequential therapy on hepatitis B (especially on HbsAg).
Interventions
solution for injection in prefilled syringe, 500 µg/ mL , 450μg /time, subcutaneous injection every 2 weeks
DRUGNivolumab
Phase I study will use 0.3, 0.75, 1.5, 3mg/kg, Q2W for 3 doses after 6 doses of P1101. Phase II study : Group I will use 3mg/kg, Q2W for 3 doses; Group III will use the dosage that determine from Phase I study 3 doses after 6 doses of P1101

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Phase I portion - Dose-limiting Toxicity | 18 weeks | To determine the potential phase 2 dose of sequestial administration of P1101 and anti-PD1. The MTD is determine by the prior dose level below the dose level at which ≥2/3 or ≥2/6 subjects suffer dose-limiting toxicity (DLT). |
| Phase II portion - Recurrence-free survival (defined as the time from randomization to HCC recurrence or death from any cause, whichever occured first) | 48 weeks | To evaluate safety(assessment of AE, SAE and unanticipated problem) and the recurrence-free survival (defined as the time from randomization to HCC recurrence or death from any cause, whichever occured first) at 48 weeks after randomization of anti-PD 1 monotherapy, P1101 monotherapy, and sequential administration of P1101 and anti-PD 1 therapy arms |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease-free survival | 48 weeks | To assess the effect of anti-PD1 monotherapy, P1101 monotherapy, and sequential administration of P1101 and anti-PD1 in inhibiting the recurrence, using disease-free survival (defined as the time from randomization to HCC recurrence, death from any cause, or onset of secondary tumor, whichever occurred first) at 48 weeks after randomization as the endpoint |
| Recurrence-free survival | 96 weeks | To assess the treatment effect of anti-PD1 monotherapy, P1101 monotherapy, or sequential administration of P1101 and anti-PD1 in inhibiting the recurrence, using recurrence-free survival (defined as the time from randomization to HCC recurrence or death from any cause, whichever occurred first) at 96 weeks after randomization as the endpoint |
| HBsAg level | End of treatment of Anti-PD1 arm is up to 6 weeks; End of treatment of P1101 arm is up to 24 weeks; End of treatment of sequential administration of P1101 and anti-PD1 is up to 18 weeks, 24 weeks and 48 weeks | To assess the change in mean HBsAg level from baseline at the end of treatment (EOT), 24 weeks and 48 weeks after randomization |
