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

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
