DURHAM, N.C. An investigational prostate cancer treatment slows the disease's progression and may increase survival, especially among men whose cancer has spread to the bones, according an analysis led by the Duke Cancer Institute.
The study, published on Nov. 19, 2013, in the journal Clinical Cancer Research, adds long-term survival and safety data for the drug tasquinimod, a new candidate for treating advanced and recurrent prostate cancer.
"While all subgroups in the clinical trial benefited from tasquinimod, those whose cancer metastasized to their bones had the greatest benefit in terms of delaying the time from the start of treatment to when the cancer progressed," said lead author Andrew J. Armstrong, M.D., ScM, associate professor of medicine at the Duke Cancer Institute. "This group of men also seemed to have a longer survival benefit when we followed them over several years."
Tasquinimod, a drug in development by Active Biotech in partnership with Ipsen, is an oral therapy that activates the body's immune system to fight cancer. Its mechanism is not fully understood, but it appears to affect the function of myeloid-derived suppressor cells, which are found in increased numbers in cancer patients. Tasquinimod is also known to block tumor blood vessel growth, a process termed angiogenesis.
New treatments approved in recent years have given physicians and patients additional options to fight prostate cancer, but the therapies typically only extend patients' lives by three to five months. New drugs that increase survival without serious side effects are still needed.
In this phase II clinical trial, funded by Active Biotech, researchers studied the use of tasquinimod among men with metastatic castration-resistant prostate cancer, an advanced form of the disease that does not respond to hormonal therapy. The study enrolled 201 men who were followed for approximately three years, with 134 randomly assi
