COPD Medicines: Industry's View continued...
In a statement jointly issued by the companies, officials elaborate on
Spiriva, saying its safety profile is confirmed by 30 clinical trials recently
analyzed by both companies but not yet published.
The statement reads, in part: "The new and expanded safety data contradicts
the conclusions about [Spiriva]" in Singh's review.
Citing "data on file" at Boehringer Ingelheim, the statement says the
analysis of 30 trials involving nearly 20,000 COPD patients, some on Spiriva,
some on placebo, found no increased risk of death from all causes or from
cardiac events nor an increased risk of stroke or heart attack.
The data reviewed, according to the statement, includes information from
findings of a trial called UPLIFT, to be presented in October at a respiratory
society meeting overseas.
Most evidence in the Singh report, the statement also points out, comes from
a single study, the Lung Health Study, which involved Atrovent, not Spiriva,
and that most deaths from cardiovascular disease occurred among patients who
didn't take their medicine.
Singh counters that even after excluding information from the Lung Health
Study, the risks remained.

doctors and say, 'Look, I read this [study], I am concerned about this." Ask
the doctor what medicines are best and why, he says.
