How Do Medical and Pharmacy Directors Perceive the Value of New Cancer Drugs?

A total of 50 health care professionals, including 25 health plan medical directors, 20 health plan pharmacy directors, and 5 pharmacy directors for pharmacy benefit management companies were surveyed regarding their perceptions of the value of 3 novel cancer therapies. The physicians and pharmacists were asked to estimate the monthly average wholesale price of each therapy, overall survival benefit of bevacizumab for treatment of persons with advanced colorectal cancer and erlotinib for treatment of persons with non–small-cell lung cancer, and progression-free survival benefit of sunitinib malate for treating persons with advanced renal cell carcinoma. Most respondents overestimated drug costs and underestimated survival benefit associated with these treatments. Mean incremental cost-effectiveness ratio for all drugs studied was approximately $170,000/quality-adjusted life-year (QALY). Cost-effectiveness ratios were lower than the $300,000/QALY cited by oncologists in another study but significantly higher than those for many other costly interventions. Our study findings reflect the need for a better understanding of the value of the clinical benefits of novel cancer therapies in an environment of product innovation but with resource constraints.

Getting allergic rhinitis under control: Part 2

Most of the symptoms of allergic rhinitis, including nasal obstruction, rhinorrhea, sneezing, and nasal itching, respond to intranasal corticosteroids administered once or twice daily. However, many patients also need to take an antihistamine for adequate control of symptoms. While an antihistamine/decongestant combination can provide symptomatic relief, it fails to address the inflammatory component of allergic rhinitis. Thus, combining an intranasal corticosteroid or oral leukotriene modifier with an antihistamine might be a more effective strategy. Factors that can facilitate treatment adherence include minimizing the number of daily doses, allowing patients to select their own dosing schedules, and providing written instructions. Specific immunotherapy can be beneficial in select patients whose allergic rhinitis symptoms are not sufficiently controlled by pharmacotherapy. (J Respir Dis. 2005;26(5):188-194)

Cyclospora cayetanensis and AIDS

A 32-year-old Hispanic woman with AIDS presented with a 1-month history of diarrhea; abdominal bloating and cramps; loss of appetite; and pronounced fatigue, malaise, and weight loss. She had no fever or chills and was not vomiting. Her CD4+ cell count was 12/µL. Results of a routine microscopic examination of stool for ova and parasites were negative; an acid-fast stain of stool demonstrated oocytes of Cyclospora cayetanensis measuring 8.8 mm in diameter (pictured, magnification ×1,000). This is about twice the size of the Cryptosporidium parvum oocyte, which typically is 4 to 5 mm.
