The Effect of PD-1/PD-L1 Inhibitor and Statin Combination Therapy on Overall Survival and Gastrointestinal Toxicity.

Objectives: Immune checkpoint inhibitors (ICIs), such as programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) inhibitors, have been approved to treat a variety of cancers. Recently, studies have suggested that ICIs and statins are synergistic. However, the addition of statins to ICI therapy may increase the risk of gastrointestinal immune-related adverse events (irAEs).

Gastrointestinal toxicities of proteasome inhibitor therapy.

Purpose: Proteasome inhibitors (PIs), which cause cell death via tumor suppressor and pro-apoptotic proteins, are integral to treatment of many hematologic malignancies but are limited by their gastrointestinal adverse effects. Evidence regarding these PI-related adverse effects is scant. In this study, we evaluated gastrointestinal adverse events caused by PIs and compared gastrointestinal toxicities between bortezomib, carfilzomib, and ixazomib.
