In a 12-week, randomized, double-blind, placeboand active-controlled clinical trial, Combivent Respimat was reportedly shownto be clinically comparable to Combivent MDI, in terms of FEV1, which is themaximal amount of air that can be forcefully exhaled in one second. In thestudy, treatment was administered to patients with COPD four times a day.
Current plans call for Combivent Respimat to beavailable to patients by mid-2012.
To allow adequate time to transition, CombiventMDI will be available until late 2013, but as of Jan. 1, 2014, CombiventRespimat will be the only Combivent product available.
"Boehringer Ingelheim invested more than 10 yearsdeveloping Combivent Respimat," said Dr. Christopher Corsico, senior vicepresident, Medicine and Regulatory for Boehringer Ingelheim PharmaceuticalsInc. "We are committed to ensuring patients and healthcare professionals areaccurately instructed on how to use the new type of inhaler, before CombiventMDI is no longer on the market."
As many as 24 million Americans may have COPD, andit is estimated that half of them remain undiagnosed. COPD is the fourth-leadingcause of death in the United States, killing one person every four minutes andmore people each year than breast cancer and diabetes combined, BoehringerIngelheim notes.
