What was measured

Tumor expression programmed death-ligand 1 (PD-L1) before and after treatment with combination MEDI-4736 and Tremelimumab will be obtained by immunohistochemistry and CytoF. The unit of measure is MMI. MMI (mean metal intensity or mean mass intensity) is a signal intensity in time-of-flight mass cytometry (CyTOF), which is the same as MFI (mean fluorescent intensity) in flow cytometry. Mean metal intensity looks more common in CyTOF to tell it from the unit in mass spectrometry. Its range is from 0 to infinity.

Analysis population: The objective was the comparison of tumor expression programmed death-ligand 1 (PD-L1) before and after treatment with combination MEDI-4736 and Tremelimumab group. Therefore, the analysis population was from one arm (MEDI4736+Tremelimumab).

Groups in this outcome

MEDI4736 + Tremelimumab

8 patients will receive an infusion of MEDI4736 (1500 mg intravenously, once) + tremelimumab (75mg intravenously, once), one to six weeks prior to surgical resection. MEDI4736: MEDI4736 is formulated at 50 mg/mL in 26 mM histidine/histidine-HCl, 275 mM trehalose dihydrate, 0.02% (w/v) polysorbate 80, pH 6.0. Tremelimumab: Tremelimumab Drug Product is formulated at a nominal concentration of 20 mg/mL in 20 mM histidine/histidine hydrochloride, 222 mM trehalose dihydrate, 0.02% (weight/volume \[w/v\]) polysorbate 80, 0.27 mM disodium edetate dihydrate (EDTA), pH 5.5.
