The purpose of this study is to test if the study drug called pembrolizumab could control the growth or shrink the cancer but it could also cause side effects. Researchers hope to learn if the study drug will shrink the cancer by half, or prevent it from growing for at least 6 months. Pembrolizumab is an antibody that targets the immune system and activates it to stop cancer growth and/or kill cancer cells.
This is an open label Phase 1b clinical trial of IV administration of OKN-007 in a pilot cohort of human recurrent malignant glioma patients. All patients will have been previously treated with the standard-of-care treatment which includes surgical resection, radiation and chemotherapy, and in some cases treatment for recurrent disease with investigational agents or bevacizumab (Avastin). Patients with unequivocal recurrence (first or greater) established by MRI with and without contrast (e.g., Gd-DTPA (Gadolinium-diethylene triamine pentacetic acid) and meeting inclusion and exclusion criteria, will be eligible for OKN-007 treatment on this protocol.
Malignant glioma are the most common and aggressive primary brain tumors in adults. Despite advances in multimodal treatment including surgery, radiation and chemotherapy, most patients have a dismal prognosis of 9-15 months (Stupp et al., NEJM 2005). A major reason for the aggressiveness of malignant glioma is a pronounced tumor neovascularization, mainly driven by the vascular endothelial growth factor (VEGF) and its receptors. The therapeutic monoclonal antibody Bevacizumab (Avastin®) inhibits the VEGF pathway by binding the VEGF ligand. In Magnetic Resonance Imaging (MRI) this treatment reduces contrast enhancement by restoring both, the blood-brain-barrier and the destabilized vessel integrity. Furthermore, it raises the sensitivity of co-administered chemotherapeutics such as Irinotecan. In conclusion, anti-angiogenic therapy leads to the problem that the routinely used MRI techniques cannot distinguish anti-vascular effects from true anti-tumor effects. The study hypothesis of the clinical trial part is that in 35% of malignant glioma patients Avastin / Irinotecan chemotherapy results in objective tumor responses assessed by standard / functional MRI and FET- /FLT-PET neuroimaging. The study hypothesis for the translational study part is that the expression of the molecular targets of Avastin and Irinotecan in malignant glioma tissue ( = tumor and vascular cells) are predictive for Avastin / Irinotecan therapy induced treatment response measured by functional MRI and FET- / FLT-PET imaging.
IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13-receptor positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells.
