The changes, which go into effect immediately, are part of “Project Impact,” a restructuring plan announced by Wyeth in January that cuts 10 percent – or about 5,000 – of its workforce. As part of Project Impact, the company will narrow its focus to find more successful new drugs especially those for which no good treatments are available. Thus, it will scale back from research on 55 diseases to only 27.

Wyeth’s new focus will be on vaccines; cancer; inflammatory disorders such as rheumatoid arthritis, severe asthma and lupus; metabolic conditions such as diabetes and obesity; musculoskeletal disorders such as arthritis and spinal fracture; and neuroscience such as Alzheimer’s and Parkinson’s disease, depression, schizophrenia and chronic pain, according to the report.

Since the Women’s Health Initiative, which found hormone replacement therapy increased a woman’s risk for breast cancer and other serious diseases and conditions, Wyeth has been faced with numerous lawsuits over its hormone replacement drugs Premarin and Prempro, which dominated the market for menopause symptom treatments for years.

According to the report, Wyeth will continue with late-stage testing on experimental menopause drugs Aprela and Pristiq. (Currently, the FDA has demanded additional research data on Pristiq.) A study of 3,400 women indicated no evidence of increased breast cancer rates. Wyeth plans to submit Aprela for FDA approval in the second half of 2009.

Prempro and Premarin , along with Provera, which is made by Pfizer, have come under attack in recent years as mounting evidence revealed that the drugs can increase the risk of developing breast cancer. Plaintiffs lodging claims against the drug makers argue that the manufacturers failed to voice sufficient warning about the increased risk of developing breast cancer that the drugs present. Approximately 5,000 women have filed lawsuits against Wyeth, contending that the company’s HRTs (hormone replacement therapies) caused them to develop breast cancer.

A study monitoring 3,400 recipients of Aprela indicated no evidence of increased breast cancer rates, compared with women who received Evista or placebo. Aprela recipients also showed the same relatively lower rates of breast tenderness and pain as Evista and placebo recipients – a significant benefit considering that breast discomfort is the main reason why stop using menopause drugs

Other studies revealed that Aprela recipients experienced better sleep and diminished hot flashes compared to women who were treated with placebo. Increased bone density, improved sexual function, and less vaginal dryness were also evident in late-stage tests of Aprela.

Wyeth will submit Aprela to the FDA for approved use in the second half of 2009. If approved, the drug may provide a better line of treatment for postmenopausal women. Its marketing would also help the company offset continual losses resulting from its Prempro suits.
