Thanks, Mike. Good afternoon, everyone. I'm pleased to report that Theravance started 2012 with significant progress across our pipeline and particularly in our respiratory programs. Recently, we were pleased to announce an agreement with GSK to increase their ownership in Theravance subject to stockholder approval. This investment reflects confidence in the respiratory collaboration programs. 2012 will be a very exciting year, with a number of significant events across our pipeline and in particular, with respiratory programs with GSK.
During the first quarter, GSK and Theravance announced top line results from the COPD and asthma registrational studies of RELOVAIR, as well as 4 non-pivotal, head-to-head Phase III studies. GSK remains on track to submit regulatory filings for RELOVAIR and COPD in the U.S. and Europe and asthma in Europe for mid-2012. In the U.S., GSK and Theravance are reviewing the asthma filing strategy.
Also during the first quarter, the first of the real-world effectiveness studies, the Salford Lung Study, was launched by GSK to investigate the potential effects of RELOVAIR versus standards of care in COPD in Europe. The effectiveness studies in COPD and asthma are intended to demonstrate the impact of once-daily dosing on patient outcomes and overall healthcare costs. As a reminder, the results of the IIIB studies will not form a part of the initial regulatory filings.
Now, turning to the LAMA/LABA program. There's 7 ongoing Phase III studies evaluating this once-daily combination dual bronchodilator for the treatment of patients with COPD. LAMA/LABA combines 2 once a day investigational bronchodilators 719, a once-daily, long-acting muscarinic antagonist or LAMA, and vilanterol, the once-daily, long-acting beta2 receptor agonist in RELOVAIR.
The overall Phase III program is evaluating over 5,000 patients globally. Completion of this program is expected by the end of the year. In our model program, we reported top line results from the Phase IIb efficacy and safety study for the lead asset 081. The results of this study and a number of ongoing non-clinical studies will inform the selection of the most appropriate dose and dosing interval for 081. In addition, progression of Phase III will be based on successful completion of these enabling studies.
Next month, GSK will be presenting clinical data from the studies of RELOVAIR and the LAMA/LABA program at the American Thoracic Society in San Francisco, California. These include presentations on the RELOVAIR Phase IIIa lung function study, the Phase I and Phase IIa for 719 and the combination of 719 and vilanterol. Other Phase III respiratory data will be presented at future medical and scientific meetings.
We believe that together, these 3 programs, RELOVAIR and LAMA/LABA and MABA have the potential to address the needs of a wide range of COPD and asthma patients suffering from these debilitating diseases.
Now, let me turn to the PuMA program and our lead compound TD-1211. Our objective with this program, and with this compound, is to restore patients to normal bowel function by alleviating gastrointestinal side effects of opioid therapy without affecting analgesia. TD-1211 is a once-daily, orally-administered, peripherally selective, multivalent inhibitor of the mu opioid receptor. Our Phase IIb program consists of 3 studies, that together address key questions that will help define the dose and dose regiment for Phase III. Enrollment is now complete in 2 of the 3 studies in the Phase IIb program and we expect to report data from these studies in the next few months.
Our other internal programs continue to progress and we look forward to providing updates on these programs later in the year. I'll now turn the conference call over to Mike Aguiar, our Chief Financial Officer. Mike?
