About this study

Official title: 3CI Study: Childhood Cancer Combination Immunotherapy. Phase Ib and Expansion Study of Nivolumab Combination Immunotherapy in Children, Adolescent and Young Adult (CAYA) Patients With Relapsed/Refractory Hypermutant Cancers

This phase Ib trial investigates the side effects of the combination of nivolumab and ipilimumab, and to see how well they work in treating patients with cancers that have come back (relapsed) or does not respond to treatment (refractory) and have an increased number of genetic changes. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Tumor mutational burden (TMB) is the total amount of genetic changes or "mutations" found in tumor cells. Some studies in adults with cancer have shown that patients with a higher TMB (an increased number of genetic changes) are more likely to respond to immunotherapy drugs. There is also evidence that nivolumab and ipilimumab can shrink or stabilize cancer in adult patients with cancer. This study is being done to help doctors learn if the combination of nivolumab and ipilimumab can help children, adolescents, and young adults patients live longer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To confirm the safety and tolerability of nivolumab-based combination therapy in children, adolescent and young adult (CAYA) patients with relapsed/refractory hypermutant cancers (including solid tumors, central nervous system [CNS] tumors, neuroblastoma, and lymphoma).

Ia. To determine the tolerability, define and describe the toxicities, and determine the recommended phase 2 dose (RP2D) of nivolumab and ipilimumab combination therapy in CAYA patients with relapsed/refractory hypermutant cancers.

SECONDARY OBJECTIVE:

  1. To assess objective overall response rate (ORR) to the nivolumab-based combination therapy in CAYA patients with relapsed/refractory hypermutant cancers within the confines of a Phase 1b study.

EXPLORATORY OBJECTIVES:

  1. To assess clinical benefit rate (CBR) (objective response and stable disease for at least two [2] protocol reassessments), progression-free survival (PFS), and overall survival (OS) following nivolumab-based combination therapy in CAYA patients with relapsed/refractory hypermutant cancers.

II. To explore correlations between tumor genotype (including tumor mutation burden [TMB], specific gene mutations, etc.) and response to nivolumab-based combination therapy in CAYA patients with relapsed/refractory hypermutant cancers.

III. To discover biomarkers predicting response of hypermutant CAYA cancers undergoing PD-1 blockade including tumor neoantigen formation, specific T-cell receptor rearrangements (TCRR) of tumor infiltrating lymphocytes (TILs), and detailed characterization and activation of the immune infiltrations including the TILs.

IV. To explore the use of minimally invasive methods to monitor and predict response to immune checkpoint inhibition in hypermutant cancers including assessment of circulating tumor deoxyribonucleic acid (DNA) and circulating T-cells immunophenotypic profiling (differentiation markers, cytokines, etc.).

OUTLINE:

PART I: Patients undergo collection of tissue samples for TMB level. Patients with elevated TMB may be eligible for Part II.

PART II: Patients are assigned to 1 of 2 dose levels.

DOSE LEVEL 1: Patients receive nivolumab intravenously (IV) over 30-90 minutes and ipilimumab IV over 30 minutes on day 1. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive nivolumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for up to 23 cycles in the absence of disease progression or unacceptable toxicity.

DOSE LEVEL -1: Patients receive nivolumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for up to 26 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks for 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Biospecimen Collection, Ipilimumab and Nivolumab in people with Constitutional Mismatch Repair Deficiency Syndrome and Hematopoietic and Lymphoid Cell Neoplasm, run by National Cancer Institute (NCI) at 9 sites in 2 countries.

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 63 inclusion and 32 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: withdrawn, as of the sponsor's last update on 10 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Canada. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Incidence of adverse events (time frame: Up to 30 days after last dose of study drug). 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 NCT04500548.

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 10 Jun 2026.
