What side effects are associated with this type of intervention?

Common treatments for brain tumors, particularly those involving BTK inhibitors like Ibrutinib and IDO inhibitors like Indoximod, often include chemotherapy agents such as cyclophosphamide and etoposide. Known side effects of these treatments include cardiotoxicity, neurocognitive dysfunction, fatigue, and an increased risk of infections. Chemotherapy agents can also cause neutropenia, thrombocytopenia, and gastrointestinal issues.

What prior FDA approvals exist?

While specific FDA approvals for Ibrutinib (BTK Inhibitor) and Indoximod (IDO Inhibitor) in the treatment of brain tumors are not detailed, other targeted therapies and immunotherapies have shown promise. For instance, dabrafenib and trametinib, which target BRAF V600E mutations, have been evaluated in clinical trials for gliomas. Additionally, temozolomide, an oral alkylating agent, is widely used for treating glioblastoma. These treatments highlight the ongoing efforts to improve outcomes for brain tumor patients through targeted and combination therapies.

What other types of research exist?

Promising novel alternatives for brain tumor patients include GD2-CAR T cell therapy for H3K27M-mutated diffuse midline gliomas, ONC201 (a selective DRD2 antagonist) for recurrent glioblastoma, and the oncolytic DNX-2401 virus for pediatric diffuse intrinsic pontine glioma. Additionally, investigational IDH-targeted approaches such as Ivosidenib and Vorasidenib for IDH-mutant gliomas are also noteworthy.

Summary

This trial tests a new treatment combining two drugs, ibrutinib and indoximod, with chemotherapy for young patients whose brain cancer has not responded to other treatments. The goal is to boost the immune system's ability to fight the cancer by blocking proteins that help cancer cells survive.

Who is the study for?

This trial is for young people aged 12-25 with relapsed or refractory primary brain cancer, such as glioblastoma or medulloblastoma. They must be able to swallow pills, have no curative treatment options left, and not be pregnant. Participants need proper kidney and liver function, controlled seizures if present, and a certain level of physical ability.

What is being tested?

The study tests the combination of Ibrutinib (BTK-inhibitor) with Indoximod (IDO-inhibitor) alongside chemotherapy drugs Cyclophosphamide and Etoposide in pediatric brain cancer patients. It aims to find the safest dose that enhances immune response against tumors without severe overlapping toxicity.

What are the potential side effects?

Potential side effects include those common to chemotherapy like nausea, fatigue, hair loss; plus specific risks from Ibrutinib such as bleeding problems or heart rhythm issues; and Indoximod may cause immune-related adverse effects.

Other Research

Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, and Indoximod, an indoleamine 2,3-dioxygenase (IDO) inhibitor, are being studied for their potential to enhance anti-tumor immune responses in brain tumor patients. Ibrutinib blocks BTK, a key enzyme in the signaling pathways of B cells, which can reduce tumor growth and survival. Indoximod inhibits IDO, an enzyme that suppresses immune responses by degrading tryptophan, thereby enhancing the body's ability to mount an immune response against tumor cells. These mechanisms are crucial for brain tumor patients as they offer a targeted approach to disrupt tumor growth and improve immune system efficacy, potentially leading to better clinical outcomes with manageable toxicity.
