About
This phase Ib trial studies the side effects and best dose of IRX-2 when given together with cyclophosphamide and nivolumab in treating patients with liver cancer that has come back or spread to other parts of the body and does not response to treatment. Biological therapies, such as IRX-2, may stimulate or suppress the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving IRX-2, cyclophosphamide, and nivolumab may work better than the IRX?2 regimen alone in treating patients with hepatocellular carcinoma.
Full description
PRIMARY OBJECTIVES:
I. To determine the safety profile of combination IRX?2 regimen and nivolumab in anti?PD?1/PD?L1 naive patients who have failed or not tolerated at least one line of treatment.
SECONDARY OBJECTIVES:
I. To evaluate the overall response rate of IRX?2 regimen combined with nivolumab using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and immune modified RECIST criteria.
II. To evaluate the rate of 6?month progression?free survival in patients treated with combination IRX?2 regimen with nivolumab.
III. To evaluate median progression?free survival and overall survival.
EXPLORATORY OBJECTIVES:
I. To evaluate the circulating T cell profiles in patients before and after therapy with the combination IRX?2 regimen and nivolumab.
II. To explore identification of tumor tissue neoantigens through a multiplex proteomic assay (MHC?PepSeq) paired with tumor genomic and transcriptomic sequencing.
III. To explore putative biomarkers (including circulating tumor deoxyribonucleic acid [DNA] and immune cell profiles) in peripheral blood to generate hypotheses for response to treatment with combination IRX?2 regimen and nivolumab.
OUTLINE: This is a dose-escalation study of IRX-2.
Patients receive nivolumab intravenously (IV) over 30 minutes on day 1, cyclophosphamide IV on day 1, and IRX-2 subcutaneously (SC) for 10 days between days 4 and 15. Cycles repeat every 28 days for up to 18 months in the absence of disease progression or unacceptable toxicity. Patients receive booster IRX-2 SC at 3, 6, 9, 12, and 15 months.
After completion of study treatment, patients are followed up every 12 weeks.

- Palliative radiation therapy is allowed to non?target lesions at the discretion of the treating physician.
- Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as outlined in RECIST version 1.1.
- Life expectancy of greater than 3 months.
- Subjects with chronic infection by hepatitis C virus (HCV) who are untreated are allowed on study. In addition, subjects with successful HCV treatment (defined as sustained virologic response [SVR] 12 or SVR 24) are allowed as long as 4 weeks have passed between completion of HCV therapy and start of study drug.
- Subjects with hepatitis B virus (HBV) may only be enrolled if their hepatitis is judged clinically stable by the investigator.
- Female patients of childbearing potential must have a negative serum pregnancy test within 7 days prior to enrollment.
- Body weight > 30 Kg.
Exclusion criteria
-
Prior exposure to PD?1/PD?L1 inhibitors.
-
Prior exposure to IRX?2 regimen.
-
Radiation therapy with a curable intent within 30 days of first dose of study treatment is excluded. However, radiation therapy with a palliative intent is allowed as long as treatment with study medication occurs >= 14 days after last dose of radiation and as long as there is at least 1 evaluable non?treated target lesion remaining.
-
Any medical contraindications or previous therapy that would preclude treatment with the IRX 2 regimen or nivolumab including the following:
- Patients with allergies to ciprofloxacin or phytohemagglutinin (PHA).
- Patients with evidence of pre?existing myelosuppression, myelodysplasia or hemorrhagic cystitis.
-
Any unresolved toxicity National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade >= 2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria.
-
Patients with grade >= 2 neuropathy will be evaluated on a case?by?case basis after consultation with the study physician.
