A Phase 1b/2 Study of Glutamine Antagonist DRP-104 in Combination With Durvalumab in Patients With Advanced Stage Fibrolamellar Hepatocellular Carcinoma (FLC)
The purpose of this study is to determine whether the combination of subcutaneous DRP-104 in combination with intravenous Durvalumab is safe and yields a clinically compelling antitumor activity measured as based on objective response rate (ORR, assessed by RECIST 1.1). Secondary objectives include progression-free survival (PFS) and overall survival (OS).
• Must have histologically confirmed FLC (Fibrolamellar Carcinoma) that is metastatic or unresectable.
• Presence of DNAJB1-PRKACA fusion transcript, assessed by RNA-sequencing, DNA-sequencing, or in situ hybridization in the archival tissue.
• Must have demonstrated radiographic progression on prior or current immunotherapy.
• Age ≥ 12 years.
• Patients \< 18 years old must have a body weight ≥ 40 kg.
• Eastern Cooperative Oncology Group (ECOG) performance status of ≤2
• Patients must have adequate organ and marrow function defined by study-specified laboratory tests.
• Patients must have adequate kidney and liver function defined by study-specified laboratory tests.
• Must have measurable disease per RECIST 1.1
• Willingness to provide tissue and blood samples for mandatory translational research.
• Women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test.
• For both Women and Men, must use acceptable form of birth control while on study.
• Ability to understand and willingness to sign a written informed consent document.
