A Pilot Study of a DNAJB1-PRKACA Fusion Kinase Peptide Vaccine Combined With Nivolumab and Ipilimumab for Patients With Fibrolamellar Hepatocellular Carcinoma
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.
• Cohort A and B: Must have histologically confirmed FLC (fibrolamellar hepatocellular cancer) that is metastatic or unresectable.
• Cohort C: Patients with histologically proven metastatic or unresectable DNAJB1-PRKACA fusion transcript positive solid tumor malignancies, non-FLC solid tumors.
• Cohort A and B: Age \> 12 years. Note: Subjects age \> 12 years but \<18 are eligible to enroll only after 6 adult patients have enrolled on the study.
• Cohort A and B: Patients \< 18 years old must have a body weight ≥40 kg.
• Cohort C: Patients must be Age ≥ 18 years.
⁃ All Cohorts:
• Presence of DNAJB1-PRKACA fusion transcript, assessed by RNA-sequencing, DNA-sequencing, or in situ hybridization in the archival tissue.
• ECOG performance status of ≤2 (Karnofsky ≥60%)
• Patients must have adequate liver, kidney and marrow function defined by study-specified laboratory tests prior to initial study drug.
• Patients must have measurable disease per RECIST 1.1.
• Must be willing to provide tissue and blood samples for mandatory translational research.
• Woman of childbearing potential must have a negative pregnancy test and follow contraceptive guidelines as defined per protocol.
• Men must use acceptable form of birth control while on study.
• Ability to understand and willingness to sign a written informed consent document.
• Patients previously treated with the vaccine targeting the DNAJB1-PRKACA fusion kinase in combination with nivolumab and ipilimumab, who, in the opinion of the principal investigator, had clinical or radiological benefits.
• Patients \< 18 years old must have a body weight ≥40 kg.
• ECOG performance status of ≤2 (Karnofsky ≥60%, see Appendix A).
