Summary

It is known that after application of MK-3475 activated PD -1 negatively regulates the activation of T cells through suppression of the path of PI3K / Akt. This study will identify the effectiveness of oral inhibitors of PI3K / Akt pathway in comparison with MK-3475 (pembrolizumab).

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Suppressor of the PI3K/Akt pathwaysExperimental Treatment1 Intervention
Pictilisib (GDC-0941) is a potent inhibitor of PI3Kα/δ. Patients will take the Pictilisib (capsules) orally with food. The dose should be taken every 3 weeks. BEZ235 (NVP-BEZ235) is a dual ATP-competitive PI3K and mTOR inhibitor. Inhibits ATR whileshown to be a poor inhibitor to Akt and PDK1. Patients will take the BEZ235 (capsules) orally with food. The dose should be taken every 3 weeks. Ipatasertib (GDC-0068) is a highly selective pan-Akt inhibitor targeting Akt1/2/3 . Patients will take the Ipatasertib (capsules) orally with food. The dose should be taken every 3 weeks. The suggested dosage of inhibitors of the PI3K/Akt pathway orally as a single dose in capsule and Packed in plastic boxes, so that preparations can be taken at home
Group II: MK-3475Active Control1 Intervention
Pembrolizumab (MK-3475) is a humanized monoclonal antibody. Information from these studies suggests that Pembrolizumab (MK-3475) may be beneficial in Glioblastoma / Gliosarcoma. * Patients enrolling in phase 1 receive MK-3475 every 3 weeks, with the dose to be determined. * MK-3475 will be given intravenously over the course of 30 minutes
