Filter by:Increasing preclinical and clinical data have shown that myeloid-derived suppressor cells (MDSCs) may represent a significant driver of immunosuppression in glioblastoma (GBM, grade IV astrocytoma) and a potential mechanism of treatment resistance to chemoradiotherapy. Tadalafil, an FDA-approved drug with inexpensive cost and excellent safety profile, has been shown to effectively reduce MDSCs and restore T-cell activation in the peripheral blood and in the tumor microenvironment. The purpose of this study is to investigate the impact of targeting MDSCs in newly diagnosed IDH-wildtype grade III-IV astrocytoma by combining tadalafil with standard of care radiation therapy (RT) and temozolomide (TMZ).
This research trial is studying the safety and effectiveness of nivolumab in combination with ipilimumab and surgery when used in the treatment of recurrent glioblastoma. The names of the study drugs involved in this study are: - Nivolumab - Ipilimumab - Placebo (IV solution with no medicine) - Zr-89 Crefmirlimab berdoxam (optional sub-study)
This is a single-arm, open-label, multicenter study in approximately 52 adults with primary (de novo) GB that has recurred or progressed (first or second recurrence, including this recurrence) after treatment(s) including surgery and radiotherapy with or without chemotherapy and following discontinuation of any previous standard or investigational lines of therapy.
O6-méthylguanine méthyltransférase (MGMT) is the main repair gene after DNA lesion induced by Temozolomide in combination with radiation therapy of Glioblastoma (GBM) in Stupp.R et al published regimen. In preclinical models, it has been demonstrated that MGMT methylation (which is silencing the DNA repair process) is achievable by folic acid. About half of the patients with operated GBM have an un-methylated MGMT gene status and therefore a poorer prognosis. A phase-1 dose escalation study is proposed with pharmacologic doses of folinic acid in combination with temozolomide and radiotherapy of operated GBM.
TVI-Brain-1 is an experimental treatment that takes advantage of the fact that your body can produce immune cells, called 'killer' white blood cells that have the ability to kill large numbers of the cancer cells that are present in your body. TVI-Brain-1 is designed to generate large numbers of those 'killer' white blood cells and to deliver those cells into your body so that they can kill your cancer cells.
The primary purpose of the study is to determine the efficacy of an investigational therapy called DCVax(R)-L in patients with newly diagnosed GBM for whom surgery is indicated. Patients must enter screening at a participating site prior to surgical resection of the tumor. Patients will receive the standard of care, including radiation and Temodar therapy and two out of three will additionally receive DCVax-L, with the remaining one third receiving a placebo. All patients will have the option to receive DCVax-L in a crossover arm upon documented disease progression. (note: DCVax-L when used for patients with brain cancer is sometimes also referred to as DCVax-Brain)
