In January 2000, three hospitals located in or around Chicago merged to form a single hospital health system. More than four years later, the Federal Trade Commission (FTC) sued to unwind the merger, claiming that it caused substantially higher prices to consumers. On October 20, 2005, an administrative law judge (ALJ) sided with the FTC and ordered the merger unwound.

In response to the emerging threat of pandemic (avian) influenza, FDA has announced the formation of a Rapid Response Team to ensure that antiviral drugs are available to citizens in the United States if they are needed. While avian flu has not emerged in this country, the team will help ensure an adequate supply of treatments, such as oseltamivir (Tamiflu, Roche) and other anti-influenza drugs, for stockpiling in the event there is an outbreak in the United States.

In an effort to meet the administration's goal of expanded electronic government, FDA is requiring drug manufacturers to submit prescription drug label information to the agency in a new electronic format. This electronic format will allow healthcare providers and consumers to more easily access the product information found in package inserts for all approved medications in the United States.

The future leadership of FDA remains highly uncertain following the unexpected resignation of commissioner Lester M. Crawford, DVM, PhD, in September. Andrew C. von Eschenbach, MD, director of the National Cancer Institute (NCI) at the National Institutes of Health (NIH), was named acting FDA commissioner, but conflict arose initially because Dr von Eschenbach wanted to retain a leadership role at NCI while also taking the helm of FDA. Although he handed over day-to-day leadership of NCI to a deputy, that move failed to fully appease critics concerned about conflicts of interest in advocating for speedy access to new cancer treatments while overseeing the safety and effectiveness of those therapies. Department of Health & Human Services (HHS) secretary Michael Leavitt has indicated that Dr von Eschenbach is not likely to get the top job at FDA on a permanent basis.

Men who have used 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors to reduce their cholesterol levels may be at less risk of developing prostate cancer, according to a case-control study published in the American Journal of Epidemiology.

Results from a 6-month, phase 3b/4 study of eszopiclone (Lunesta, Sepracor) in adult patients with chronic insomnia demonstrated that nightly use of eszopiclone 3 mg resulted in statistically significant improvements (P<.0001) compared with placebo in patient-reported measures of sleep latency (onset of sleep), sleep maintenance, total sleep time, and sleep quality. These results were announced in late September at the American Neurological Association (ANA) Annual Meeting in San Diego, Calif.

Results from a phase 3 clinical study demonstrate that a novel transdermal estradiol gel (Bio-E-Gel, BioSante) represents a major improvement in low-dose estrogen therapy, significantly reducing the frequency and severity of hot flashes in menopausal women in a dose-dependent manner at all 3 doses studied, with the low dose being identified as the lowest effective approach, stated James A. Simon, MD, at the North American Menopause Society's 16th annual meeting in San Diego.

A single IV bolus of enoxaparin (Lovenox, Aventis) is just as effective as and associated with less bleeding than unfractionated heparin in patients undergoing elective PCI, said Gilles Montalescot, MD. Dr Montalescot was lead investigator of STEEPLE (Safety and Efficacy of Enoxaparin in Percutaneous Coronary Intervention Patients), the results of which were announced during the the ESC Congress 2005 in Stockholm, Sweden.

In other drug safety news, FDA has announced the selection of Gerald J. Dal Pan, MD, MHS, as director, Office of Drug Safety in the Center for Drug Evaluation and Research (CDER). Dr Dal Pan, selected from a strong field of candidates as part of a nationwide search, will lead the agency's post-marketing drug safety program.

Evaluation of newly released medications for potential formulary inclusion should focus on clinical benefit over product price or rebate. Dossiers are invaluable to the evaluation process, but it's important to note that dossiers obtained from pharmaceutical manufacturers are often incomplete, according to presenters at AMCP's 2005 Educational Conference last month in Nashville, Tenn.

Incremental cost-effectiveness ratios produced by pharmacoeconomic modeling are the gold standard for evaluating drug alternatives, but the result of such an analysis often requires a value judgment on the part of the managed care organization (MCO), Daniel C. Malone, PhD, RPh, said at the Academy of Managed Care Pharmacy's (AMCP's) 2005 Educational Conference last month in Nashville, Tenn.

Accumulating data have demonstrated that the endothelin axis plays a role in the progression of many malignancies. Endothelin-1, which is produced by prostate cancer cells, can stimulate new bone formation. It can also act synergistically with a number of growth factors promoting cancer cells growth and proliferation. Over-expression of endothelin-1 and diminished capacity for its clearance have been seen in prostate cancer cell lines. The highest concentration of endothelin-1 is found in patients with hormone refractory metastatic disease. Atrasentan (Xinlay, Abbott) is a member of a new class of drugs called the selective endothelin-A receptor antagonists (SERAs). The safety and efficacy of atrasentan in hormone refractory prostate cancer (HRPC) have been evaluated in several clinical trials. Atrasentan demonstrated some efficacy in delaying the progression of disease and improving patients' quality of life while having an acceptable safety profile. An NDA for atrasentan was submitted in December 2004 for..

FDA actions in brief

FDA extended the Prescription Drug User Fee Act action date to January 7, 2006, for lenalidomide (Revlimid, Celgene). The drug is intended to treat patients with transfusion-dependent anemia resulting from low- or intermediate-1-risk myelodysplastic syndromes associated with a deletion 5q cytogenetic abnormality.

In each issue, Formulary's "Focus on" article reviews a newly approved or investigational drug of interest to pharmacy and therapeutics committee members. Because so many readers have told the editors of Formulary that they reference this column frequently when making formulary decisions for their hospitals, health systems, or managed care organizations, the editors have compiled this review of all the "Focus on" articles published so far in 2005, along with updates on the status of each agent.

HEPATITIS B AND C are serious viral diseases that can lead to lifelong infection, cirrhosis, liver cancer, liver failure and death. They often produce chronic, hidden infections. An estimated 1.25 million Americans are infected with hepatitis B, and about 30% of them have no signs or symptoms. An estimated 2.7 million Americans have chronic hepatitis C, and about 80% of them have no signs or symptoms. Both diseases are transmitted through blood and other bodily fluids.
