One of largest COPD trials ever conducted confirms comparable safety and
efficacy profile of SPIRIVA® Respimat®* 2.5
µg (once a day, two puffs)†† and SPIRIVA® HandiHaler® 18 µg

  • Time to first COPD exacerbation was comparable for both SPIRIVA® (tiotropium) formulations: Respimat® 2.5 µg (once a day, two puffs) and HandiHaler® 18 µg1
  • Building on the on-treatment mortality benefit of SPIRIVA® 18 µg via HandiHaler® vs. control in the milestone trial UPLIFT‡2, the TIOSPIR™ trial showed a similar impact on survival between SPIRIVA® Respimat® and SPIRIVA® HandiHaler®1
  • With broad inclusion criteria, the TIOSPIR™ trial population was
    representative of typical, real-world COPD patients, including patients
    with all COPD disease assessment categories (GOLD§ groups A-D), comprehensive use of concomitant COPD medications, and
    patients with a history of cardiac disorders

BURLINGTON, ON, Sept. 9, 2013 /CNW/ – TIOSPIR™ (Tiotropium Safety and Performance in Respimat®), with over 17,000 COPD patients included and one of the largest
international COPD trials ever conducted, confirmed the comparable
safety and efficacy profile of the two SPIRIVA® formulations – SPIRIVA® Respimat® 2.5 μg (once a day, two puffs) and SPIRIVA® HandiHaler® 18 μg.1 The trial included two SPIRIVA® delivery systems, the unique Respimat® inhaler and the dry powder inhaler HandiHaler®.1

The highly-anticipated results from the three year trial were published
in the New England Journal of Medicine (on September 8, 2013). TIOSPIR™ was designed to provide evidence of the
relative safety and efficacy profile of the investigational SPIRIVA® Respimat®2.5 μg (once a day, two puffs), or Respimat® 1.25 μg (once a day, two puffs)** compared with SPIRIVA® HandiHaler® 18 µg.†† TIOSPIR™ was specifically designed to be of an adequate size and
duration, to enable analysis of all-cause mortality and time to first
COPD exacerbation in a large COPD patient population, with broad
inclusion criteria, which closely reflects the real-world COPD patient
population.1

Commenting on the results, Dr. Andrew McIvor, Professor of Medicine,
McMaster University, Firestone Institute for Respiratory Health, St.
Joseph’s Healthcare, said, “TIOSPIR™ is a landmark clinical trial which included 50 sites in Canada,
providing evidence of the safety and efficacy of tiotropium delivered
either by HandiHaler
® or Respimat® in a broad population of COPD patients, including those with a history
of cardiovascular disease. Importantly, the TIOSPIR™ trial reinforces
that physicians can be confident in continuing to prescribe
SPIRIVA® HandiHaler® as a proven maintenance therapy across the spectrum of different
severities of COPD patients
.”

Efficacy as measured by time to first COPD exacerbation
The TIOSPIRTM trial demonstrated comparable results for time to first COPD
exacerbation for both formulations of SPIRIVA®. In particular, the median time to COPD exacerbation was approximately
two years for both formulations. For SPIRIVA® Respimat® 2.5 µg (once a day, two puffs) this was 756 days compared to 719 days
for SPIRIVA® HandiHaler® 18 µg.1

COPD exacerbations have a significant impact on patients’ lives3,4,5,6 and reducing their frequency and severity are principal goals of COPD
treatment.7 The TIOSPIR™ results demonstrate that Respimat® and HandiHaler® showed comparable results for time to first COPD exacerbation,
exacerbation frequency as well as rate of COPD exacerbations associated
with hospitalization.

TIOSPIR™ builds upon the established efficacy profile of SPIRIVA® HandiHaler® as demonstrated in several trials, including the four year UPLIFT®‡‡2 trial as well as a large-scale trial, POET-COPD®§, which was specifically powered to investigate COPD exacerbations.8

  • In the UPLIFT®‡‡ trial, SPIRIVA® 18 µg via HandiHaler® was associated with reduction in the risk of exacerbations, related
    hospitalizations and respiratory failure vs. control (placebo)2,9
  • SPIRIVA® 18 µg via HandiHaler® demonstrated a 28 per cent reduction in the risk of a COPD exacerbation
    leading to hospitalization vs. the active comparator, the long-acting
    beta2 agonist salmeterol, as observed in the POET-COPD®§§ trial8
  • In a separate trial, SPIRIVA® Respimat® 2.5 µg (once a day, two puffs) had a significant reduction in the risk
    of COPD exacerbations vs. placebo
    (31 per cent decrease)***10

Safety as measured by survival rates
The three year TIOSPIR™ trial also showed an equal impact on survival –
as measured by all-cause mortality for tiotropium (SPIRIVA® Respimat® 2.5 µg (once a day, two puffs) vs. HandiHaler® 18 µg).1 This adds to evidence from the UPLIFT®‡‡ trial in which Spiriva® HandiHaler® (18 µg) reduced the risk of death compared to control by 16 per cent
(placebo) (P=0.016) and suggests an equally beneficial effect of the
two SPIRIVA® formulations on survival.11

Importantly TIOSPIR™ also demonstrated that:

  • The incidence of adverse events and major adverse cardiovascular events
    was similar between the treatment groups1
  • In patients with a history of cardiac arrhythmia, SPIRIVA® Respimat® 2.5 μg (once a day, 2 puffs) and SPIRIVA® HandiHaler® 18 µg showed similar impact on survival as measured by all-cause
    mortality1

COPD in Canada
Currently, COPD is the fourth leading cause of death in Canada and is
expected to be the third leading cause of death worldwide by the year
2020.12,13 Furthermore, mortality rates from COPD have risen over the past 15
years, particularly in women.12

It is estimated that hospital admissions for COPD lung attacks average a
10-day stay with a cost associated at approximately $10,000, resulting
in an estimated total cost of COPD hospitalizations at a cost of $1.5
billion
annually.14 Furthermore, over the next 25 years, it has been suggested that COPD
will be responsible for approximately $101.4 billion in societal costs.
The best strategy to reduce this financial burden is by reducing the
number of COPD exacerbations that individuals experience.15

About TIOSPIR™1
TIOtropium Safety and Performance In Respimat® (TIOSPIR™), a global landmark trial in more than 17,000 patients, was
one of the largest chronic obstructive pulmonary disease (COPD) trials
ever conducted. Participants were recruited between May 2010 and April
2011
and were randomized to treatment in more than 1,200 investigator
sites in 50 countries. The trial compared the safety and efficacy of
SPIRIVA® Respimat® inhaler 2.5 μg (once a day, two puffs),††† or SPIRIVA® Respimat® 1.25 μg (once a day, two puffs)‡‡‡ with SPIRIVA® HandiHaler® 18 µg. Over the three-year duration of the trial, TIOSPIR™ demonstrated
that SPIRIVA® Respimat® 5 μg or 2.5 µg have similar exacerbation, safety and efficacy outcomes
to the well-established profile of SPIRIVA® HandiHaler® 18 µg in COPD. In a spirometry substudy of TIOSPIR™, involving 1,370
participants, Respimat® 5 μg was non-inferior to HandiHaler® for FEV1, but the Respimat® 2.5 μg dose was not.

SPIRIVA® is delivered via HandiHaler®, a breath-actuated, single-dose dry powder inhaler, or by SPIRIVA® Respimat® Inhaler™ propellant-free, new generation inhaler that combines
innovative technology with the proven efficacy of SPIRIVA®.*
