A novel strategy devised by Dana-Farber Cancer Institute scientists has proved highly effective in killing drug-resistant multiple myeloma cells in the laboratory and could open a new form of attack on the deadly blood cancer, they report. Highly encouraged by the findings, the researchers hope to move rapidly to clinical trials of the therapy, a combination of the drug Velcade and an experimental compound that was designed by researchers at the Broad Institute of Massachusetts Institute of Technology and Harvard University. The report, which will be posted online this week by the Proceedings of the National Academy of Sciences (http://www.pnas.org/papbyrecent.shtml), demonstrates that the combination was more than twice as effective as either drug alone in killing resistant cells from patients’ bone marrow. The promise is particularly exciting, scientists say, because many patients don’t respond to Velcade, a drug approved just two years ago that’s been an important new therapy for multiple myeloma, a disease which caused an estimated 11,000 deaths in 2004, according to the Multiple Myeloma Research Foundation.
