Theravance Reports Fourth Quarter and Full Year 2010 Financial Results

SOUTH SAN FRANCISCO, CA -- (Marketwire - February 15, 2011) - Theravance, Inc. (NASDAQ: THRX) reported today its financial results for the fourth quarter and full year ended December 31, 2010. Revenue for the full year was $24.2 million. Net loss for the fourth quarter and full year of 2010 was $19.3 million and $83.9 million, respectively, compared with $22.2 million and $85.3 million for the same periods of 2009. Net loss per share was $0.25 and $1.16 for the fourth quarter and full year of 2010, respectively, compared with a net loss per share of $0.35 and $1.35 for the same periods of 2009. Cash, cash equivalents and marketable securities totaled $309.6 million as of December 31, 2010.

"Theravance had a successful 2010 highlighted by significant progress across a number of our key programs including RELOVAIR™, MABA, and PµMA," said Rick E Winningham, Chief Executive Officer. "In addition, I am pleased with the recent progression into Phase 3 of the LAMA/LABA program with GSK. This dual bronchodilator product candidate potentially will provide an important new treatment for patients suffering from COPD. In 2011, our focus will be on RELOVAIR™ and advancing our pipeline."

Program Highlights

Respiratory Programs

RELOVAIR™ Phase 3a Programs

The RELOVAIR™ Phase 3a programs in chronic obstructive pulmonary disease (COPD) and asthma are progressing and enrollment in the studies is largely in line with expectations. RELOVAIR™ is an investigational once-daily medicine that combines fluticasone furoate or FF (an inhaled corticosteroid or ICS) and vilanterol or VI (a long-acting beta2 agonist or LABA) for the treatment of patients with COPD or asthma. RELOVAIR™ Phase 3a programs in COPD and asthma have now enrolled over 9,000 patients out of an expected 11,000 patients in total.

The Phase 3a pivotal program in COPD consists of five studies, including two 12-month exacerbation studies, two six-month efficacy and safety studies, and a detailed lung function profile study.

The Phase 3a asthma pivotal program consists of eight studies to determine the safety and efficacy of RELOVAIR™ in asthma patients who remain uncontrolled on current treatment. These studies include an exacerbation study, a 12-month safety study (which also supports the COPD program), a 12-week low-dose combination efficacy study, a 24-week high-dose combination efficacy study, a 24-week head-to-head study of RELOVAIR™ versus Advair®/Seretide®, a 24-week study of FF versus fluticasone propionate (FP), a 12-week study of VI versus salmeterol, and a hypothalamic-pituitary-adrenal (HPA) axis study.

RELOVAIR™ Phase 3b Program: Initiation of Outcomes Study in COPD

In early February 2011, we and GSK announced the start of a large Phase 3b outcomes study with RELOVAIR™ in COPD. This is an extensive study of 16,000 patients to assess the potential for RELOVAIR™ to improve survival in patients with COPD and a history of, or at risk from, cardiovascular disease. This Phase 3b study is an extensive outcomes trial across 1,100 global sites and will run alongside the existing COPD program. The results are not expected prior to the anticipated regulatory submission and will not form part of the initial New Drug Application (NDA)/Marketing Authorisation Application (MAA).

The primary objective is to evaluate prospectively the effect of the combination (FF/VI, 100/25mcg) compared with placebo on survival in patients with moderate COPD and a history of, or at risk from, cardiovascular disease. Secondary objectives will evaluate the effect of FF/VI compared with placebo on the rate of decline in lung function, as well as on cardiovascular endpoints including cardiovascular death, heart attacks and strokes.

This study will evaluate the clinical outcomes of patients receiving standard cardiovascular care (including cardiovascular medications) versus patients receiving FF/VI in addition to receiving standard cardiovascular care (including cardiovascular medications).

This is a four arm, multicenter, randomized, double-blind, parallel-group study, with treatment administered once daily via a novel dry powder inhaler. The total duration of the study will be determined by the number of events in the study, with each patient being treated for between 15 and 44 months based on current estimates.

LAMA/LABA Combination (GSK573719/Vilanterol or '719/VI)

In early February 2011, we and GSK announced the initiation of the Phase 3 program for the once-daily LAMA/LABA dual bronchodilator '719/VI which will evaluate over 5,000 patients globally. '719/VI combines two bronchodilator molecules currently under development -- '719, a long-acting muscarinic antagonist (LAMA) and VI, a LABA. These molecules act through two mechanisms: antagonism of acetylcholine muscarinic receptors and agonism of beta2 adrenoreceptors. This investigational medicine will be administered using a new dry powder inhalation device.

A 52-week study to evaluate the long term safety and tolerability of '719 (125mcg) alone, as well as the combination '719/VI (125/25mcg), began in February 2011, and will be followed by four large pivotal studies that will compare improvements in lung function between '719/VI, its components, placebo and tiotropium. The Phase 3 program also will include two further studies assessing the effect of '719/VI on exercise endurance. The Phase 3 program will investigate two doses of '719 (125mcg and 62.5mcg) and '719/VI (125/25mcg and 62.5/25mcg) across the six studies, which are expected to commence within the next quarter.

Inhaled Bifunctional Muscarinic Antagonist-beta2 Agonist (MABA)

In December 2010, we and GSK announced that the first patient had started treatment with GSK961081 ('081) in a Phase 2b study in patients with moderate to severe COPD. '081 is a single molecule with both muscarinic antagonist and beta2 receptor agonist (MABA) activities. The primary objective of this study is to evaluate dose response, dose interval, efficacy, and safety of '081 by studying once-daily (QD) doses (100mcg, 400mcg, and 800mcg) and three twice-daily (BID) doses (100mcg, 200mcg, and 400mcg) and the active comparator salmeterol 50mcg BID compared with placebo over a 28-day period. The overall aim of this Phase 2b study is to evaluate the safety and efficacy of '081 administered both once daily and twice daily over a 28-day period to allow the selection of a well-tolerated and efficacious dose and dosing interval to take forward into Phase 3 development.

Central Nervous System (CNS)/Pain Program

Peripheral Mu Opioid Receptor Antagonist (PµMA) -- TD-1211

In October 2010, we announced positive proof-of-concept results with TD-1211 in patients with opioid-induced constipation (OIC). TD-1211 is an investigational once-daily, orally-administered, peripherally selective, multivalent inhibitor of the mu opioid receptor designed to alleviate gastrointestinal side effects of opioid therapy without affecting analgesia. We intend to progress TD-1211 into further Phase 2 work in 2011.

Financial Results

Revenue

Revenue was $6.9 million for the fourth quarter of 2010 compared with $3.8 million for the same period in 2009, an increase of $3.1 million. During the fourth quarter, $0.6 million of royalty revenue was earned from VIBATIV™ net sales of $3.2 million. For the full year of 2010, revenue was $24.2 million, compared with $24.4 million for the full year of 2009.

Research and Development

Research and development expense for the fourth quarter of 2010 decreased to $17.5 million compared with $18.4 million for the same period in 2009. For the full year of 2010, research and development expense was $75.1 million compared with $77.5 million for the full year of 2009. The decrease for the fourth quarter and the full year of 2010 was primarily due to lower external expenses, partially offset by higher employee-related expenses. Total external research and development expense for the fourth quarter and full year of 2010 (including reimbursements) was $1.3 million and $12.2 million respectively, compared with $3.3 million and $13.8 million, respectively, for the fourth quarter and full year of 2009. Total research and development stock-based compensation expense for the fourth quarter and full year of 2010 was $2.6 million and $10.3 million, respectively, compared with $2.6 million and $11.5 million, respectively, for the fourth quarter and full year of 2009.

General and Administrative

General and administrative expense for the fourth quarter of 2010 increased to $7.4 million from $6.4 million for the same period in 2009. For the full year of 2010, general and administrative expense was $27.5 million compared with $27.1 million for the full year of 2009. The increase in the fourth quarter and the full year of 2010 was primarily due to higher employee-related expenses partially offset by lower external costs. Total general and administrative stock-based compensation expense for the fourth quarter and full year of 2010 was $2.1 million and $8.7 million, respectively, compared with $2.0 million and $8.5 million, respectively, for the fourth quarter and full year of 2009.

Cash and Cash Equivalents

Cash, cash equivalents and marketable securities totaled $309.6 million as of December 31, 2010, an increase of $117.1 million during the fourth quarter. This increase was primarily due to GSK's purchase of $129.4 million of common stock in November 2010, partially offset by cash used in operations.
