A rebrand for proteasome inhibition in solid tumors via continuous hepatic artery infusion.

Targeting tumors with proteosome inhibitors has demonstrated antitumor activity and has been successfully translated to the clinic for patients with multiple myeloma. However, in patients with solid tumors, treatment with proteosome inhibitors as single agents has consistently failed to yield meaningful responses. In our study, we investigate the potential of hepatic artery infusion pump delivery of carfilzomib, to continuously direct a large dose to the tumor with least hepatic toxicity.
