Studies: New Asthma Drug Safe, Effective

Xolair May Also Help With Year-Round Nasal Allergies

From Asthma to Allergies continued...

Drugs are approved by the FDA for specific medical problems; however, doctors are free to prescribe a drug for other conditions. This practice is known as an "off-label use."

In a study of close to 300 people with year-round allergies, treatment with Xolair for four months significantly decreased nasal allergy symptoms compared with placebo. Use of antihistamines was also significantly less in the Xolair group. No safety concerns arose during the study.

Lanier says he believes compliance among asthma patients will be better with Xolair than with traditional treatments.

"I have been doing asthma trials for 30 years, and one question is always whether or not patients will keep taking a drug," he says. "In this case, the answer was a resounding yes. Compliance was incredibly high because people felt so much better on this drug."
