Gossypol plus navitoclax COMBO in CLL ...early study

The researchers found a very effective drug combination of gossypol plus navitoclax to kill CLL cells in the lab.

From the article...

Doctors at Dartmouth-Hitchcock's Norris Cotton Cancer Center (NCCC) have found a combination of drugs to potentially treat chronic lymphocytic leukemia (CLL) more effectively. The research was published online on May 3, 2013, and it will appear as a letter in the journal Leukemia, a publication of the prestigious Nature Publishing Group. The study helps address a basic problem of treating CLL.

"Both drugs have been given to patients, but never in combination, because no one had the mechanistic rationale for doing that. Now we have what we think is the most promising drug combination so far for the treatment of CLL," says Eastman.

CLL cells in the lymph nodes have an increased level of a protein known as BCL-X. Gossypol likely inhibits this protein, which allows the navitoclax to work more effectively to kill the cancer cells. Eastman and his team tested this drug combination on CLL immediately after they came out on the patients.

The willingness of the patients to participate was integral to this study," Eastman adds. "After 40 years of research, I think this is the most promising idea I have had that might truly impact patient outcome."

The researchers hope a clinical trial will soon follow.

Hi Its good news that more drugs are coming on line it gives a hopeful future.


Both these drugs have been around about ten years, the news here is using them in combination. How they will work in humans is yet to be seen...
