Analyst · Robert W. Baird. Your line is now open
Thanks, Renee. Good afternoon, everyone, and thank you for joining us. The third quarter was a period of significant progress for Theravance Biopharma during which we continued to focus our target market uptick for VIBATIV, our first commercialized product and made progress with our lead development programs, our long-acting muscarinic antagonist TD-4208 and our peripherally-restricted opioid antagonist Axelopran or TD-1211. We plan to spend the next few minutes providing some color on these programs. We will also touch on some very exciting recent Phase 1 data that we announced earlier this week on TD-6450, our novel NS5A inhibitor to treat HCV. We are planning more complete review at our upcoming Investor and Analyst Day on Friday, December 12th at the Millennium Hotel Broadway in New York and that -- and our meeting will begin that day at 9 o'clock in the morning. I hope you all marked your calendars and are planning to join us for this event. I’ll start with VIBATIV. We reintroduced VIBATIV into the U.S. market about one year ago with a highly focused strategy, as well as a phased commercial strategy, deploying approximately six reps in target territories. We believe that VIBATIV has an important therapeutic value, commercial potential and strategic significance for our company and we are committed to its success. VIBATIV came from our laboratories. We invented it. We developed it. We’ve got it approved, now with two major indications for difficult-to-treat Gram-positive infection. We believe this medicine is now beginning to gain traction in our targeted markets. There is an increasing recognition within the global medical and scientific community and among public health and governmental bodies of the serious threat of bacterial resistance and the urgent need societally for new antibiotics solutions. We think VIBATIV has the profile the type of antibiotics that’s needed today and in the future to address increasingly challenging Gram-positive bacterial infection environment, particularly those that are difficult-to-treat. VIBATIV’s dual mechanism of action inhibits both bacterial cell wall synthesis, as well as disrupts bacterial cell membrane function. Importantly, VIBATIV is bactericidal and can be dosed once a day. With total days of therapy for MRSA infection in United States estimated approximately 35 million in 2014, we think the opportunity for VIBATIV is very meaningful. We are undertaking a number of initiatives, design to enhance healthcare practitioners understanding of the therapeutic utility of VIBATIV and highlight the product as an important tool in the anti-infective treatment arsenal. First let me discuss our Phase 3 bacteremia program. Bacteremia was a bloodstream infections represent significant healthcare system challenge and it’s associated with significant morbidity and mortality. When reviewing the bloodstream infection data from both our HABP/VABP as well as our complicated skin Phase 3 programs, we saw evidence that VIBATIV may offer an opportunity for patients with Gram-positive bacteremia. In addition, other investigator initiated studies reported successful treatment of Gram-positive bloodstream infections with VIBATIV. Given the challenge associated with treating Gram-positive bacteremia, we decided to pursue a Phase 3 clinical program in bacteremia. Later this year we plan to initiative a registrational multi-center, randomized, open-label study for the treatment of patients with Staph aureus bacteremia. The study is designed to evaluate VIBATIV and treating Staph aureus bacteremia as compared to standard therapy. Key secondary outcome measures of the study include an assessment of the duration of bacteremia post-randomization and the incidence of metastatic complications, as compared to standard therapy. If we are successful in this indication, VIBATIV would become the only branded antibiotic approved for these three major indications for difficult to treat Gram-positive infections. Secondly, we intend to conduct an observational use registry study, called TOUR, designed to assess the manner in which VIBATIV is being used by healthcare practitioners to treat patients. By broadly collecting and examining data related to VIBATIV treatment patterns, clinical effectiveness and safety outcomes in the real world, we aim to create an expansive knowledge base to guide future development and optimal use of the drug. We are targeting enrollment of this registry’s first patient in late 2014. And finally, we are in the process of expanding our sales and marketing activities to improve or position an institution coverage in our targeted territories. Specifically, we are expanding our sales reps from six to 20 and we will have one medical science liaison in the field for every two sales reps. This expansion is designed to enable us to reach more healthcare providers. Current prescribers have told us as they gain more experience with VIBATIV, they increased their uses of drug and its approved indications. Our institutional reorder patterns in our targeted territory suggests the same dynamic. As I mentioned, VIBATIV has important strategic value to Theravance Biopharma, it’s our first commercialized product and the cornerstone of our evolution into a full integrated company advancing products from the laboratory to the market. For any biopharma company, the business and cultural shift to a commercial stage business is a major transition and we believe our company is successfully making that transition. Now let’s turn to TD-4208. First, I will talk about the market opportunity we see for TD-4208 and then I will ask Mathai to add some additional comments on the program, as well as discuss Axelopran and TD-6450 and Velusetrag. The respiratory market is one that we know well and in which we have considerable expertise in both discovery and development. We believe TD-4208 can be a valuable addition to the COPD treatment regimen and that represents a significant commercial opportunity for our company. Here is how we do the market opportunity for TD-4208. Once daily long-acting muscarinic antagonists are currently the cornerstone of maintenance therapy for patients with COPD and are widely available for use, but only in handheld inhalers. Not all patients who have COPD prefer or able to tolerate handheld inhalers. Patient population that uses nebulized products for long-term maintenance therapy represents an underserved and assessable market segment. These patients are defined partly by their disease severity. They are further defined by their functional status, including cognitive and dexterity issues, which can preclude being able to manage handheld bronchodilators. In addition, doctors report that they prefer to use nebulized therapy in select COPD patients to ensure they inhale their medication properly. We believe the commercial opportunity for nebulized product that addresses the needs of these COPD patients is significant. This is a devastating disease affecting a growing number of people. More than 12.5 million patients in the United States alone have COPD and the American Lung Association notes that COPD is a third leading cause of death in the U.S. Looking at United States alone, our market data suggests that 9% or approximately 1 million treated COPD patients use a nebulized product on an ongoing basis for delivery of their regular maintenance therapy. Muscarinic antagonists are the preferred mechanism for single-agent bronchodilator therapy in patients with COPD and handheld products with single most commonly prescribed maintenance therapy is a once-daily LAMA or tiotropium, which had sales of approximately $5 billion. In the nebulizer segment, there is no once-daily or twice daily muscarinic antagonist therapy available. There's only one nebulized muscarinic antagonist available, tiotropium, which is taken every six hours. Today, there are only two nebulized beta-2 agonists available and these are taken every 12 hours. Today, there have been no once-daily nebulized therapies approved and yet 9% of patients still prefer nebulizer maintenance therapy over handheld inhalers. We believe there is a core U.S. market opportunity for 4208, as the first nebulized long-acting muscarinic antagonist, providing convenience of once-daily dosing via any standard nebulizer. With 4208, we believe we can offer therapeutic option that could enhance and enable treated COPD patients that require or prefer nebulized therapy to access the same gold-standard therapy of those COPD patients who use the handheld inhalers. While initially an important market opportunity, 4208 monotherapy resides in the nebulized maintenance setting for the treatment of COPD, we believe that there are additional opportunities beyond this market. As we’ve discussed before, we can see a significant potential for 4208 as a foundation for combination products and delivery in metered dose inhaler and dry powder inhaler products. And with that, I'll turn the call over to Mathai to expand on the 4208 clinical data. Mathai?
