Gastroenterologists at Rush University Medical Center are studying the safety and efficacy of a new system for delivering chemotherapy for patients with esophageal cancer, a rare, but deadly disease that attacks the throat.
The unique drug therapy delivers a highly concentrated dose of chemotherapy injected directly on to the hard-to-reach tumors in the esophagus non-surgically. Researchers at Rush are trying to determine if the gel treatment can reduce the size of the cancerous tumors.
Patients diagnosed with esophageal cancer are usually diagnosed at very advanced stages and not only have to undergo chemoradiation therapy, but may also have an esophagectomy, which is a surgical procedure to remove a part of or the entire esophagus.
"Patients with esophageal cancer have very few treatment options and life expectancy can be less than two years from first diagnosis," said Dr. Sohrab Mobarhan, principal investigator of the study and clinical director of the Coleman Foundation Comprehensive Clinic for Gastrointestinal Cancers at Rush. "This also could potentially be a viable treatment option for patients who have inoperable tumors located in their esophagus."
The investigational drug, called OncoGel, is made of two major components, the ReGel drug delivery system, which is a gel made up of ingredients used in biodegradable stitches, and paxclitaxel, a well established, FDA-approved anti-cancer chemotherapy agent. Patients receive a one-time injection of OncoGel during an endoscopy.
"In pilot studies, OncoGel has been shown to continuously release paclitaxel, which is the chemotherapy agent, in concentrated doses at a higher magnitude than in just delivering it through the blood for up to six weeks," said Mobarhan.
