About this study

Official title: A Phase 1b Trial of the IRX-2 Regimen and Nivolumab in Patients With Advanced Hepatocellular Cancer (HCC)

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.

Read the detailed description

PRIMARY OBJECTIVES:

  1. 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:

  1. 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:

  1. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cyclophosphamide, Cytokine-based Biologic Agent IRX-2 and Nivolumab in people with Recurrent Hepatocellular Carcinoma and Refractory Liver Carcinoma, run by City of Hope Medical Center at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 35 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 21 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recommended phase II dose (time frame: Up to 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03655002.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2026.
