Tykerb helpful in reducing stem cells in breast cancer
LONDON A new cancer drug called Tykerb from GlaxoSmithKline may help stop breast cancer from recurring because of its ability to decrease tumor-causing breast cancer stem cells, according to published reports.
Dr. Angel Rodriguez from the Lester and Sue Smith Breast Center, Baylor College of Medicine in Houston engaged in a study that involved 45 patients with breast cancer and showed a significant amount of tumor regression within six weeks of treatment, according to published reports.
Tykerb is also identified as lapatinb and works by targeting cell surface receptors, which may be helpful in terminating cancer in the long run. According to Dr. Rodriguez, “Rather than the broad brush approach, in which cells are killed indiscriminately, targeting the stem cells may be more effective and also prevent some of the unpleasant side effects associated with conventional chemotherapy treatment.”
It costs $2,000 to $3,000 a month to purchase Tykerb in the United States, and according to published reports, Glaxo feels that Tykerb has the qualities to become a blockbuster medicine, although its sales have been low.
Analysis shows pain reduction for fibromyalgia patients using Lyrica
CHICAGO A pooled analysis presented at the annual Academy of Neurology meeting reports that Pfizer’s Lyrica reduced pain in patients with fibromyalgia, whether or not they experienced symptoms of anxiety or depression.
The results were determined by analysis of data from three clinical trials that used a placebo as a control ranging from eight weeks, to 13 weeks and finally 14 weeks in more than 2,000 patients that had fibromyalgia. According to published reports, they also studied different dosages given to patients and where asked to measure their pain from a scale of zero to 10. The analysis confirmed that pain reduction was the greatest change in patients who used the drug regardless of whether they still had feelings of depression or anxiety.
According to published reports, Fibromyalgia is the most common, chronic pain condition in the United States, and patients who have it usually experience symptoms of poor sleep, stiffness and fatigue.
According to Dr. Lesly Arnold, one the authors of the study and associate professor in the department of psychiatry at the University of Cincinnati Medical Center, “The data showed that Lyrica reduced fibromyalgia pain, and alleviating that pain was associated with patients’ overall feeling of well-being. Understandably, many patients with a chronic pain condition, such as fibromyalgia, also experience depression and anxiety, and importantly we found that Lyrica helped reduce pain in patients regardless of the presence of symptoms of these co-morbid conditions.”
NACDS urges Congress to refrain from adopting e-pedigree mandate
ALEXANDRIA, Va. New federal legislation to require that pharmacies and drug wholesalers establish electronic pedigrees for every drug they sell or distribute would throw both industries into turmoil and add “extraordinary” costs to their operations, the head of the National Association of Chain Drug Stores warned Thursday.
The Safeguarding America’s Pharmaceuticals Act of 2008 was introduced Thursday by Reps. Steve Buyer, (R-Ind., and Jim Matheson, D-Utah. If passed and signed into law, the bill would mandate electronic pedigree requirements to assist in the tracking and tracing of prescription drugs in the domestic supply chain.
NACDS president and chief executive officer Steve Anderson responded quickly to the proposal. “While instances of drug counterfeiting may occur,” he said, a federal e-pedigree mandate is the wrong approach.
“Despite the perception that e-pedigree and track and trace mandates are quick solutions, their adoption and implementation would be extremely complex and costly for retail pharmacies and others in the supply chain, and without the desired benefit,” Anderson asserted. “These systems are many years away from full development, have not been fully tested and lack uniform standards and patient privacy safeguards.”
There are alternatives to assure a safer drug supply as the industry gears up for e-pedigrees, Anderson added. Among them: adopting tougher uniform federal licensing standards for drug distribution and using the Food and Drug Administration to certify that manufacturers, distributors and pharmacies follow secure supply-chain guidelines.
“These steps would go a long way in improving safety and further protecting the supply chain by building on effective systems currently in place,” Anderson said.
