FDA approves Gleevec for expanded use in patients with rare gastrointestinal cancer‏


The U.S. Food and Drug Administration today granted Gleevec (imatinib) regular approval for use in adult patients following surgical removal of CD117-positive gastrointestinal stromal tumors (GIST). Today’s action also highlights an increase in overall patient survival when the drug is taken for 36 months rather than the standard 12 months of treatment.
Gleevec was originally granted accelerated approval for the treatment of advanced or metastatic GIST in 2002. In 2008 Gleevec received a subsequent accelerated approval for adjuvant use that is for the treatment of patients with GIST who had had potentially curative resection (surgical removal) of GIST tumors, but who were at increased risk for a recurrence. The accelerated approval program provides earlier patient access to promising new drugs while the confirmatory clinical trials are being conducted. Regular approval for the metastatic GIST indication was also granted in 2008.
GIST is a rare form of cancer that originates in cells found in the wall of the GI tract. These cells, known as interstitial cells of Cajal, are part of the autonomic nervous system, which regulates body processes such as food digestion. More than half of GISTs start in the stomach.

Contact Precautions May Have Unintended Consequences

Contact precautions, including gloves, gowns, and isolated rooms, have helped stem the transmission of hospital pathogens but have also had some negative consequences, according to findings from a new study. Healthcare worker (HCWs) visited patients on contact precautions less frequently than other patients and spent less time with those patients when they did visit, report Daniel J. Morgan, MD, from the University of Maryland School of Medicine and the Veterans Affairs (VA) Maryland Health Care System, Baltimore, and colleagues. Moreover, patients on contact precautions also received fewer outside visitors. "Less contact with HCWs suggests that other unintended consequences of contact precautions still exist," Dr. Morgan and coauthors write. "The resulting decrease in HCW contact may lead to increased adverse events and a lower quality of patient care due to less consistent patient monitoring and poorer adherence to standard adverse event prevention methods (such...

Obama Renominates Tavenner to Be CMS Chief

President Barack Obama yesterday renominated Marilyn Tavenner, the acting administrator of the Centers for Medicare & Medicaid Services (CMS), to serve in that post without the caveat of "acting" attached to it. If the Senate approves her nomination, Tavenner will be the first confirmed, full-fledged CMS administrator since Mark McClellan, MD, PhD, stepped down from that position in October 2006, during the George W. Bush administration. Dr. McClellan's successors either were acting administrators or, in the case of Donald Berwick, MD, who was Tavenner's immediate predecessor, a recess appointment. As illustrated by Dr. Berwick's  CMS history , Senate confirmation can be tough to get when one party has enough votes to filibuster and otherwise stymie a nomination by an opposing party's president. That was the case when Obama nominated Dr. Berwick, whom Senate Republicans portrayed as an advocate of healthcare rationing, a characterization denied by t...

Secondary Prevention: Clinical Approaches to Managing the Higher-Risk Patient with Heart Disease

INCIDENCE/PREVALENCE/BURDENS ASSOCIATED WITH CARDIOVASCULAR DISEASE (CVD) The prevention of an initial and recurrent cardiovascular event and other complications, such as diabetes and kidney failure [also known as end-stage renal disease (ESRD) or chronic kidney disease (CKD) stage 5] is an important goal in patients with a history of CVD. Each year, approximately 185,000 Americans suffer a recurrent stroke, approximately 470,000 will have a recurrent coronary attack, and an estimated 325,000 will suffer a recurrent myocardial infarction. [1]  Secondary prevention strategies offer the opportunity to prevent further complications and improve outcomes by early detection and management of common comorbidities. The burden on public health and the costs associated with chronic illnesses such as CVD, CKD, and diabetes remain high. An estimated 82.6 million American adults (1 in 3) have 1 or more types of CVD. [1]  Heart failure is the fastest-growing clinical cardiac disease ...
