Theravance and Elan Enter Into a $1.0 Billion Royalty

SOUTH SAN FRANCISCO, CA and DUBLIN, IRELAND--(Marketwired - May 13, 2013) - Theravance, Inc. (NASDAQ: THRX) and Elan Corporation, plc (NYSE: ELN) today announced that they have entered into a royalty participation agreement wherein Elan will purchase a participation interest in potential future royalty payments related to four respiratory programs partnered with GlaxoSmithKline plc (GSK): RELVAR™ ELLIPTA™/BREO™ ELLIPTA™, ANORO™ ELLIPTA™, MABA (Bifunctional Muscarinic Antagonist-Beta₂ Agonist) monotherapy (GSK961081, or MABA '081), and vilanterol (VI) monotherapy. Under the terms of the agreement, Elan will make a one-time cash payment of $1.0 billion to Theravance in exchange for a 21% participation interest in the potential future royalty payments from the four programs when, as and if received by Theravance.

"We are very excited to partner with Elan in a transaction that recognizes the significant value of four programs from our GSK collaborations targeted at respiratory disease," said Rick E Winningham, Theravance's Chief Executive Officer. "This agreement complements our strategy to facilitate and accelerate the return of capital to our stockholders and build value, consistent with our recently announced plan to separate Theravance into two entities, Royalty Management Company and Theravance Biopharma."

Mr Kelly Martin, Chief Executive Officer of Elan commented, "This transaction, upon closing, will immediately diversify our business with an investment in four high quality and late stage clinical assets within a large and growing therapeutic area. This diversification should benefit our shareholders by spreading the inherent risk embedded in any one specific asset. In addition, the long term and future potential cash flow streams and net income will be shared with investors both directly -- through a dividend pass through -- and indirectly through overall after tax earnings."

Mr Martin added, "Being involved, even indirectly, with an important therapeutic area that addresses the needs of millions of patients who suffer from respiratory disease is particularly meaningful to all of us at Elan."

RELVAR™ ELLIPTA™/BREO™ ELLIPTA™ (fluticasone furoate (FF)/vilanterol (VI)), ANORO™ ELLIPTA™ (umeclidinium bromide (UMEC)/VI) and VI monotherapy have been developed under the LABA collaboration with GSK. For RELVAR™ ELLIPTA™/BREO™ ELLIPTA™ and VI, Theravance is entitled to receive royalties from GSK of 15% of the first $3.0 billion of combined annual global net sales, and 5% of combined annual global net sales above $3.0 billion. If ANORO™ ELLIPTA™ is approved and commercialized, royalties on annual global net sales are upward tiering and range from the mid-single digits to 10%. The transaction does not include any royalty participation interest associated with UMEC/VI/FF, an investigational medicine also in development under the LABA collaboration with GSK.

MABA '081 is an investigational medicine in development under the strategic alliance between Theravance and GSK. If MABA '081 is successfully developed and commercialized as monotherapy, Theravance is entitled to receive royalties from GSK of between 10% and 20% of the first $3.5 billion of annual global net sales, and 7.5% of all annual global net sales above $3.5 billion. The transaction does not include any royalty participation interest associated with MABA '081 in combination with any other therapeutically active component, including an inhaled corticosteroid, or any other MABA compound as monotherapy or in combination.

The transaction is not subject to any material conditions, other than approval by Elan's shareholders. Elan plans to promptly prepare the required documentation to enable a shareholder vote, which Elan has agreed to hold within 35 days. If approved by Elan's shareholders, the parties expect the transaction to be consummated by the end of June 2013.

Theravance Tax Treatment and Use of Proceeds

Theravance does not expect to pay significant income taxes associated with the transaction.

As previously disclosed, Theravance intends to separate its biopharmaceutical operations and its late stage partnered respiratory assets into two independent publicly traded companies, referred to as Theravance Biopharma and Royalty Management Co, respectively. We intend for Royalty Management Co to be the primary vehicle for the return of capital and that the proceeds from this transaction will facilitate and accelerate returns to its stockholders following the separation. Theravance Biopharma will be primarily focused on the discovery, development and commercialization of small-molecule medicines in areas of significant unmet medical need. This transaction does not change the overall structure of the planned separation, including which assets are expected to be in each company. Additionally, we do not plan to increase 2013 research and development spending above what was included in our 2013 expense guidance. Theravance is currently evaluating the optimal strategies to return capital to stockholders of Royalty Management Co following completion of the separation, including through dividends or the repurchase of shares and/or convertible debt.

Centerview Partners LLC is acting as financial advisor and Skadden, Arps, Slate, Meagher & Flom LLP and Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP are acting as legal advisors to Theravance in connection with the transaction.

Evercore Partners and Ondra Partners are acting as financial advisors to Elan. Cadwalader, Wickersham & Taft LLP and A&L Goodbody are acting as legal advisors to Elan in connection with the transaction.

About Four Respiratory Programs

RELVAR™ ELLIPTA™/BREO™ ELLIPTA™, ANORO™ ELLIPTA™, VI monotherapy and MABA monotherapy (GSK961081, or MABA '081), are assets developed in collaboration with GlaxoSmithKline plc (GSK).

In November 2002, Theravance entered into its LABA collaboration with GSK to develop and commercialize once-daily long-acting beta₂ agonist (LABA) products for the treatment of chronic obstructive pulmonary disease (COPD) and asthma. For the treatment of COPD, the collaboration is developing two combination products: (1) RELVAR™ ELLIPTA™ or BREO™ ELLIPTA™ (FF/VI), an investigational once-daily combination medicine consisting of a LABA, vilanterol (VI), and an inhaled corticosteroid (ICS), fluticasone furoate (FF) and (2) ANORO™ ELLIPTA™ (UMEC/VI), a once-daily investigational medicine combining a long-acting muscarinic antagonist (LAMA), umeclidinium bromide (UMEC), with a LABA, VI. For the treatment of asthma, the collaboration is developing FF/VI. BREO™ ELLIPTA™ 100/25 mcg is approved in the United States as an inhaled long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and/or emphysema. It is also indicated to reduce exacerbations of COPD in patients with a history of exacerbations. RELVAR™ ELLIPTA™ for the treatment of COPD and asthma patients is currently under review by the European Medicines Agency (EMA) and Japan. FF/VI is not approved or licensed in the European Union or anywhere outside of the United States. ANORO™ ELLIPTA™ for the treatment of COPD patients is currently under review by the U.S. Food and Drug Administration, the EMA and Japan. The Prescription Drug User Fee Act goal date for ANORO™ ELLIPTA™ is December 18, 2013. ANORO™ ELLIPTA™ (UMEC/VI) is an investigational medicine and is not currently approved anywhere in the world.

In March 2004, Theravance entered into its strategic alliance with GSK. Under this alliance, GSK received an option to license exclusive development and commercialization rights to product candidates from certain of Theravance's discovery programs on predetermined terms and on an exclusive, worldwide basis. In 2005, GSK licensed Theravance's MABA program for the treatment of COPD. GSK961081 ('081), the lead MABA, is an investigational, single molecule bifunctional bronchodilator with both muscarinic antagonist and beta₂ receptor agonist activities. Based on the results from a Phase 2b study, GSK and Theravance plan to advance '081 monotherapy into Phase 3 and the '081/FF combination into Phase 3-enabling studies, later in 2013.

Important Safety Information

BREO ELLIPTA is contraindicated in patients with severe hypersensitivity to milk proteins or who have demonstrated hypersensitivity to either fluticasone furoate, vilanterol, or any of the excipients.

BREO ELLIPTA should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of COPD, or as rescue therapy for the treatment of acute episodes of bronchospasm, which should be treated with an inhaled, short-acting beta₂-agonist.

BREO ELLIPTA should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medications containing LABAs, as an overdose may result.

Oropharyngeal candidiasis has occurred in patients treated with BREO ELLIPTA.

An increase in the incidence of pneumonia has been observed in subjects with COPD receiving the fluticasone furoate/vilanterol combination, including BREO ELLIPTA 100 mcg/25 mcg, in clinical trials. There was also an increased incidence of pneumonias resulting in hospitalization. In some incidences these pneumonia events were fatal.

Patients who use corticosteroids are at risk for potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. A more serious or even fatal course of chickenpox or measles may occur in susceptible patients.

Particular care is needed for patients who have been transferred from systemically active corticosteroids to inhaled corticosteroids because deaths due to adrenal insufficiency have occurred in patients with asthma during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids.

Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage of inhaled corticosteroids in susceptible individuals.

Caution should be exercised when considering the coadministration of BREO ELLIPTA with long‐term ketoconazole and other known strong CYP3A4 inhibitors because increased systemic corticosteroid and cardiovascular adverse effects may occur.

Inhaled medicines can produce paradoxical bronchospasm, which may be life-threatening. Vilanterol, the LABA in BREO ELLIPTA, can produce clinically significant cardiovascular effects in some patients. Decreases in bone mineral density have been observed with long-term administration of products containing inhaled corticosteroids, as have glaucoma, increased intraocular pressure, and cataracts.

The most common adverse reactions (≥3% and more common than in placebo) reported in two 6-month clinical trials with BREO ELLIPTA (and placebo) were nasopharyngitis, 9% (8%); upper respiratory tract infection, 7% (3%); headache, 7% (5%); and oral candidiasis, 5% (2%). In addition to the events reported in the 6-month studies, adverse reactions occurring in ≥3% of the subjects treated with BREO ELLIPTA in two 1-year studies included COPD, back pain, pneumonia, bronchitis, sinusitis, cough, oropharyngeal pain, arthralgia, hypertension, influenza, pharyngitis, diarrhea, peripheral edema, and pyrexia.

BREO ELLIPTA is not indicated for the relief of acute bronchospasm or the treatment of asthma. The safety and efficacy of BREO ELLIPTA in patients with asthma have not been established. Long-acting beta₂-adrenergic agonists (LABAs), such as vilanterol, one of the active ingredients in BREO ELLIPTA, increase the risk of asthma-related death. A placebo-controlled trial with another LABA (salmeterol) showed an increase in asthma-related deaths in subjects receiving salmeterol. This finding with salmeterol is considered a class effect of all LABAs, including vilanterol.
