Omalizumab shown to improve chronic rhinosinusitis with nasal polyps

The monoclonal antibody omalizumab, already approved to treat allergic asthma and urticaria, has been shown to improve symptoms of patients who have chronic rhinosinusitis and nasal polyps (CRSwNP), according to recent research released as an abstract from the American Academy of Allergy, Asthma, and Immunology annual meeting. The AAAAI canceled the meeting and provided abstracts and access to presenters for press coverage.

“When you give this drug to patients who have nasal polyposis and concomitant asthma, you are effectively treating both the upper and lower airway disease components,” Jonathan Corren, MD, of the University of California, Los Angeles, said in an interview. “Typically, people with nasal polyp disease have worse nasal disease than people without asthma. In addition, asthma is also generally worse in patients with nasal polyposis,” he added.

Dr. Corren reported results of a subset of patients with corticosteroid-refractory CRSwNP and comorbid asthma enrolled in phase III, placebo-controlled, 24-week, trials of omalizumab, POLYP1 (n = 74) and POLYP2 (n = 77). The analysis excluded patients who were on oral steroids or high-dose steroid inhaler therapy so the effectiveness of omalizumab could be evaluated without interfering factors, Dr. Corren explained. As a result, the study population consisted of patients with mild to moderate asthma. Dr. Corren is also principal investigator of the POLYP1 trial.

The analysis compared changes in Asthma Quality of Life Questionnaire (AQLQ) and sino-nasal outcome test (SNOT-22) measures after 24 weeks of treatment with those seen with placebo.

“With regard to asthma outcomes, we found there was a significant increase in the odds ratio that patients who received omalizumab would achieve a minimal, clinically important improvement in their asthma quality of life,” Dr. Corren said .

The study estimated the odds ratio for minimal clinically important difference in AQLQ at 24 weeks was 3.9 (95% confidence interval, 1.5-9.7; P = .0043), which Dr. Corren called “quite significant.” SNOT-22 scores showed a mean improvement of 23.3 from baseline to week 24, compared with a worsening of 8.4 in placebo (P = .0001).

Omalizumab is approved for treatment of perennial allergies and urticaria. Chronic rhinosinusitis with nasal polyps would be a third indication if the Food and Drug Administration approves it, Dr. Corren noted.

Genentech sponsored the subset analysis. Hoffmann-La Roche, Genentech’s parent company, is sponsor of the POLYP1 and POLYP2 trials. Dr. Corren disclosed financial relationships with Genentech.
