Summary

The primary objective of the trial is the safety and tolerability of administering a vaccine targeting the DNAJB1-PRKACA fusion kinase, in combination with nivolumab and ipilimumab in patients with unresectable or metastatic FLC and with non-FLC solid tumors and to assess the T-cell response.

Conditions

  • Fibrolamellar Hepatocellular Carcinoma (FLC)

Interventions

DRUG

DNAJB1-PRKACA peptide vaccine

1. DNAJB1-PRKACA peptide vaccine: Day 1, 8, 15 of cycle 1 and on Day 1 of cycle 2, 3 and 4 (priming phase). Boost vaccinations: every 3 cycles beginning C5D1. 2. Drug: 0.3 mg DNAJB1-PRKACA peptide vaccine + 0.5mg Poly-ICLC

DRUG

Nivolumab

1. Nivolumab 3mg/kg will be administered as a 30 minute IV infusion (-10/+15min) on Day 1 of Cycle 1-4 during the priming phase. Boost/maintenance vaccinations will be administered as a flat dose of 480mg every 4 weeks starting on Day 1 of Cycle 5. 2. Drug: 3mg/kg and 480mg IV

DRUG

Ipilimumab

1. Ipilimumab (1 mg/kg) will be administered as a 30 minute IV infusion (-10/+15min) on Day 1 of Cycles 1, 2, 3 and 4 of the study, every 3 weeks of the priming phase. 2. Drug: 1mg/kg IV
