St. Francis researchers study use of gene transfer vaccine for lung cancer

INDIANAPOLIS – Researchers at the St. Francis Hospital & Health Centers are seeking patients with non-small cell lung cancer to test the safety and effectiveness of an investigational drug designed to significantly prolong survival.

The study involves Lucanix®, which is administered as a vaccine. It’s made from irradiated gene-modified tumor cells. The purpose is to see how well it works compared with a placebo in treating patients with late stage non-small cell lung cancer.

“We want to see if this therapy retrains the patient's immune system to recognize and kill the cancer cells,” said principal investigator Michael Slaughter, M.D., Ph.D, a member of St. Francis Medical Group. “Earlier published test results of Lucanix have shown the survival of patients was double at two years, compared to historic controls – an encouraging outcome not previously seen in advanced lung-cancer patients.”

Slaughter is among a group of top oncologists testing Lucanix, which is manufactured by NovaRx Corp. Similar studies are being conducted throughout the United States, Canada, United Kingdom, Germany, Poland, the Netherlands, Hungary, India and Serbia/Montenegro.

Slaughter is joined by several St. Francis sub-investigators, including Stephen Eberwine, M.D.; Nadeem Ikhlaque, M.D.; Mary Lou Mayer, M.D.; Stephen Eric Rubenstein, M.D.; Subhash Sharma, M.D.; and Gregory W Smith, M.D.

To be considered for the trial, patients must be between the ages of 18 and 75; have stage IIIA, IIIB, and IV non-small-cell lung cancer; and have completed platinum-based chemotherapy but did not progress on it.

Gene transfer is the process of inserting new laboratory-modified genes into a patient. Many scientists this type of therapy might be an effective way to treat certain health problems.
