Study finds Teva allergy drug safe, effective

JERUSALEM — A drug under development by Teva Pharmaceutical Industries appears safe and effective in treating allergies, according to results of a late-stage clinical trial released Monday.

Teva said a 529-patient phase-3 trial of Qnasl (beclomethasone dipropionate) nasal aerosol showed the drug produced a "significant" improvement in patients with seasonal and perennial allergies. Patients received either 320 mcg of Qnasl or a placebo.

Results of the trial were presented Monday at the American Academy of Allergy, Asthma and Immunology's 2012 meeting in Orlando, Fla.
