portfolio to maximize value. After a review of all our therapeutic areas, in 2008, we announced our decision to exit certain disease areas—anemia, atherosclerosis/hyperlipidemia, bone health/frailty, gastrointestinal, heart failure, liver fibrosis, muscle, obesity, osteoarthritis (disease modifying concepts only) and peripheral arterial disease—and give higher priority to the following disease areas: Alzheimer's disease, diabetes, inflammation/immunology, oncology, pain and psychoses (schizophrenia). We also will continue to work in many other disease areas, such as asthma, chronic obstructive pulmonary disorder, genitourinary, infectious diseases, ophthalmology, smoking cessation, thrombosis and transplant, among others. These decisions did not affect our portfolio of marketed products, the development of compounds currently in Phase 3 or any launches planned over the next three years. Notwithstanding our efforts, there are no assurances as to when, or if, we will receive regulatory approval for additional indications for existing products or any of our other products in development. Below are significant regulatory actions by, and filings pending with, the FDA and regulatory authorities in the E.U. and Japan.

We received “not-approvable” letters from the FDA for Fablyn (lasofoxifene) for the prevention of post-menopausal osteoporosis in September 2005 and for the treatment of vaginal atrophy in January 2006. We submitted a new NDA for the treatment of osteoporosis in post-menopausal women in December 2007, including the three-year interim data from the Postmenopausal Evaluation And Risk-reduction with Lasofoxifene (PEARL) study in support of the new NDA. In September 2008, nine of the 13 members of an FDA advisory committee concluded that there is a population of women with post-menopausal osteoporosis for which the benefit of treatment with Fablyn is likely to outweigh the risks. In January 2009, we received a “complete response” letter from the FDA for the Fablyn submission. The FDA is seeking additional data and we are working with the FDA to determine the appropriate next steps regarding our application.

In September 2008, we received a “complete response” letter from the FDA for the Spiriva Respimat submission. The FDA is seeking additional data and we are working with the FDA to provide the additional information.

In September 2007, we received an "approvable" letter from the FDA for Zmax that sets forth requirements to obtain approval for the pediatric AOM indication based on pharmacokinetic data. A supplemental filing for pediatric AOM and sinusitis remains under review.

In December 2005, we received an "approvable" letter from the FDA for our Vfend pediatric filing, which sets forth the additional requirements for approval. We have been systematically working through these requirements and addressing the FDA's concerns, including initiating an additional pharmacokinetics study in November 2008.

In June 2008, we completed the acquisition of Encysive, whose main product is Thelin. In June 2007, Encysive received a third "approvable" letter from the FDA for Thelin for the treatment of PAH. We began an additional Phase 3 clinical
