The Gateway for Cancer ResearchSM (www.demandcurestoday.org) announces an exciting new Gateway-funded phase II study using ADAPT therapy for treatment of metastatic colorectal cancer based on a 2010 AACR presentation by Dr. Lin and his collaborators.
“As a stage IV colorectal cancer patient, I hoped to live another two years to see my daughter through to age 11. Thanks to Dr. Lin's treatment protocol, I am healthy and am hoping for another 50 years”
The clinical trial, being led by Dr. Edward Lin, a medical oncologist at the University of Washington, Fred Hutchinson Cancer Research Center and an accomplished researcher and expert in gastrointestinal cancers, is the first to specifically target colon cancer stem cells.
The study will use a unique combination drug therapy of Capecitabine (a chemotherapy drug) and Celecoxib (an FDA approved arthritis medication) to "wake up" and to "kill" colon cancer stem cells. The treatment works by activating cancer stem cells that hibernate during chemotherapy—a chief cause of treatment failure—so they can be destroyed. The proper sequence is necessary to consistently kill the dormant cells. The ADAPT concept was proposed by Drs. Lin and Linheng Li, a prominent stem cell biologist.
It is a very powerful drug combination with good preliminary results. Pilot studies have shown significantly increased survival rates compared with conventional therapy. Of 124 treated patients, 40% of those treated with this protocol achieved complete remission or near remission with a median survival of 93.7 months and only 1/3 of the patients had surgical removal of the metastasis. The average length of survival for stage IV colorectal cancer patients on conventional treatment is about 20-24 months and 46 months for complete responders.
"A lot of patients we didn't expect to see live, are living and thriving," says Dr. Lin. It also allows a good quality of life for patients. "The treatment is offering an immediate benefit to today's cancer patients. 95% of participants are out and about in their daily lives, doing what they need to do without skipping a beat."
Thomas Oberdorf, a 5-year colorectal cancer survivor who benefitted from Dr. Lin's treatment protocol is grateful. "As a stage IV colorectal cancer patient, I hoped to live another two years to see my daughter through to age 11. Thanks to Dr. Lin's treatment protocol, I am healthy and am hoping for another 50 years," said Oberdorf who did not miss a beat as CFO of a large organization during the course of his treatment.
The drug combination allowed a good quality of life for most patients. An independent randomized phase III study also showed that celecoxib reduced capecitabine induced hand foot syndrome that was observed by Dr. Lin.
Tiffany Heigle, a stage IV colon cancer patient when she first met with Dr. Lin, credits him for 10 years of survival and precious time with her family. "Because of Dr. Lin's new treatment approach, I can enjoy being a mom to my 18-year-old freshman in college and my 15-year-old freshman in high school," says Heigle." I have been allowed to see them grow up due to this research."
