Spots Global Cancer Trial Database for Chemo-immunotherapy Using Ibrutinib Plus Indoximod for Patients With Pediatric Brain Cancer

Study Description

Brief Summary: Recent lab-based discoveries suggest that IDO (indoleamine 2,3-dioxygenase) and BTK (Bruton's tyrosine Kinase) form a closely linked metabolic checkpoint in tumor-associated antigen-presenting cells. The central clinical hypothesis for the GCC2020 study is that combining ibrutinib (BTK-inhibitor) with indoximod (IDO-inhibitor) during chemotherapy will synergistically enhance anti-tumor immune responses, leading to improvement in clinical response with manageable overlapping toxicity. GCC2020 is a prospective open-label phase 1 trial to determine the best safe dose of ibrutinib to use in combination with a previously studied chemo-immunotherapy regimen, comprised of the IDO-inhibitor indoximod plus oral metronomic cyclophosphamide and etoposide (4-drug combination) for participants, age 12 to 25 years, with relapsed or refractory primary brain cancer. Those previously treated with indoximod plus temozolomide may be eligible, including prior treatment via the phase 2 indoximod study (GCC1949, NCT04049669), the now closed phase 1 study (NLG2105, NCT02502708), or any expanded access (compassionate use) protocols. A dose-escalation cohort will determine the best safe dose of ibrutinib for the 4-drug combination. This will be followed by an expansion cohort, using ibrutinib at the best safe dose in the 4-drug combination, to allow assessment of preliminary evidence of efficacy.
