Olodaterol Shows Sustained Improvements in Lung Function in Patients with Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD)

Ridgefield, CT, September 8, 2013 – Data from the olodaterol Phase 3 clinical program, presented for the first time at the European Respiratory Society (ERS) Annual Congress 2013 in Barcelona, showed the addition of olodaterol 5 and 10 µg delivered once daily via the Respimat^® inhaler provided improvements in lung function in patients with moderate to very severe chronic obstructive pulmonary disease (COPD). Olodaterol is an investigational long-acting beta agonist (LABA) currently being studied as a once-daily maintenance bronchodilator treatment of airflow obstruction in patients with COPD, including chronic bronchitis and/or emphysema.

These data are from two sets of replicate, 48-week pivotal studies evaluating the long-term efficacy and safety of once-daily olodaterol in 5 and 10 µg doses, as well as two sets of replicate, 6-week studies investigating olodaterol's 24-hour bronchodilation profile. In an effort to more accurately represent the clinical practice setting, patients involved in the Phase 3 program were allowed to continue their usual care, with the exception of LABAs. Usual care included long- and short-acting anticholinergics, short-acting beta agonists, inhaled corticosteroids (ICS) and xanthines.

"Despite advances in the treatment of COPD, there remains a significant need to reduce the burden of COPD on patients' lives," said lead study author Gary T. Ferguson, MD, of the Pulmonary Research Institute of Southeast Michigan, Livonia, Michigan. "We are excited about these data because we see that the lung function improvements shown with olodaterol may translate into patient-related benefits over and above those seen with usual care, and these improvements on top of permitted bronchodilator therapies makes these positive results even more noteworthy."

Of the more than 20 presentations from the Boehringer Ingelheim lung health portfolio being presented at this year's ERS Congress, five are from the Phase 3 olodaterol clinical program.

"We are encouraged by these findings and have an ongoing commitment to bringing new treatment options to patients with COPD," said Tunde Otulana, MD, senior vice president, Clinical Development and Medical Affairs, Boehringer Ingelheim Pharmaceuticals, Inc. "Our leadership role in lung health is driven by our heritage and passion for finding ways to address the unmet needs of the millions of Americans living with debilitating lung diseases such as COPD."

Key Results from the 48-Week Phase 3 Olodaterol Studies
In one set of 48-week Phase 3 pivotal studies (NCT00782210 and NCT00782509), olodaterol 5 and 10 µg delivered once daily via the Respimat^® inhaler provided statistically significant improvements in lung function, as measured by FEV₁, versus placebo plus usual care in patients with moderate to very severe COPD (P < 0.05; n=613 and 635). 

In a second set of 48-week studies (NCT00793624 and NCT00796653), the same dose and delivery of olodaterol provided comparable improvements in lung function compared to 12 µg formoterol twice daily in these COPD patients (n=904 and 934). After 24 weeks of treatment, both doses of olodaterol and formoterol provided statistically significant improvements in FEV₁ AUC_0-3.

Olodaterol 5 µg was shown to provide significant improvement (P < 0.0001) in lung function within five minutes following the first dose.

In addition, COPD patients had less need for both day- and night-time rescue medication when using both doses of olodaterol (5 and 10 µg) delivered once daily via the Respimat^® inhaler and formoterol versus placebo over the 48-week treatment period (P < 0.01).

In these studies, there was no significant difference in adverse events between the olodaterol treatment arm and the control arm with 71.0 percent of patients receiving olodaterol 5 µg reporting an adverse event compared to 72.7 percent of patients receiving olodaterol 10 µg, 70.8 percent of patients receiving placebo and 69.1 percent of patients receiving formoterol 12 µg. The most common adverse reactions were nasopharyngitis, dizziness, rash and arthralgia.

Key Results from the 6-Week Phase 3 Olodaterol Studies
In the two replicate, randomized, double-blind, placebo-controlled crossover studies, patients received olodaterol 5 µg and 10 µg delivered once daily via the Respimat^® inhaler, tiotropium 18 µg once daily via the HandiHaler^® or placebo in addition to usual care (ICS and xanthines) for 6 weeks (n=108 and 122).

The data presented at ERS showed that the improvements seen in lung function with olodaterol, as measured by FEV₁ responses, were maintained over 24 hours (P < 0.001):
