HIV Protease Inhibitor Therapy for Liposarcoma
Name of the Trial
Why This Trial Is Important
Nelfinavir, a drug used in the treatment of human immunodeficiency virus (HIV) infection, may be able to help stop the growth of liposarcoma. Nelfinavir is a protease inhibitor, a type of drug that interferes with the ability of certain enzymes (proteases) to break down proteins, which is a process that is necessary for some cells and viruses to reproduce.
In HIV-infected patients, nelfinavir often interferes with the growth of fat cells. This characteristic led researchers to test the drug on liposarcoma cells in the laboratory. The research showed that nelfinavir slowed the growth of liposarcoma cells and caused them to undergo apoptosis (programmed cell death).
In this trial, researchers will test nelfinavir in patients with advanced liposarcoma to see if it helps shrink their tumors. They will also seek to establish the drug's maximum tolerated dose and its pharmacokinetics (fate of the drug in the body) in these patients.
"Currently, we don't have very many options available to treat liposarcoma that recurs or metastasizes," said Dr. Chow. "We need to develop a new therapy that targets the key molecular pathways of this cancer. Nelfinavir is a drug that is already FDA approved and has shown promise in laboratory tests, and so we hope to see evidence of clinical activity in this trial."
