Results of a Phase III clinical trial showed that a simple drug regimen of two anti-clotting drugs - clopidogrel and aspirin - lowered the risk of stroke by almost one-third, compared to the standard therapy of aspirin alone, when given to patients who had minor or transient stroke symptoms to prevent subsequent attacks.

A promising new treatment for breast cancer being developed at Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine (VIMM) has been shown in cell culture and in animal models to selectively kill cancer stem cells at the original tumor site and in distant metastases with no toxic effects on healthy cells, including normal stem cells.

A drug approved in Europe to treat osteoporosis has now been shown to stop the growth of breast cancer cells, even in cancers that have become resistant to current targeted therapies, according to a Duke Cancer Institute study. The findings, presented June at the annual Endocrine Society meeting in San Francisco, indicate that the drug bazedoxifene packs a powerful one-two punch that not only prevents estrogen from fueling breast cancer cell growth, but also flags the estrogen receptor for destruction.

Aspirin is known to lower risk for some cancers, and a new study led by a UC San Francisco scientist points to a possible explanation, with the discovery that aspirin slows the accumulation of DNA mutations in abnormal cells in at least one pre-cancerous condition.

Advanced metastatic melanoma is a disease that has proven difficult to eradicate. Despite the success of melanoma-targeting drugs, tumors inevitably become drug resistant and return, more aggressive than before. In the current issue of the journal Cancer Cell, however, researchers at The Wistar Institute describe how they increase the effectiveness of anti-melanoma drugs by combining anticancer therapies with diabetes drugs.

The BMJ and Channel 4 Dispatches investigated and found that evidence suggesting potential harm from the drugs in industry studies has not been published. Some independent studies challenge the conclusions of the drugs manufacturers' own research. Now some medical experts and patient groups are calling on the pharmaceutical companies to be more transparent in reporting of study data and to enter into dialogue about safety concerns.

A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent, according to new Northwestern Medicine research. In MS, the immune system attacks and destroys myelin, the insulating layer that forms around nerves in the spinal cord, brain and optic nerve.
