Genentech Announces FDA Approval of Xolair (omalizumab) for Adults with Nasal Polyps
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has approved the company’s supplemental Biologics License Application (sBLA) for Xolair (omalizumab) for the add-on maintenance treatment of nasal polyps in adult patients 18 years of age and older with inadequate response to nasal corticosteroids. Nasal polyps can lead to a loss of smell and nasal congestion, and frequently co-occur with other respiratory conditions, such as allergies and asthma. With this approval, Xolair is now the first biologic for the treatment of nasal polyps that targets and blocks immunoglobulin E (IgE), a key driver of inflammation.
“With Xolair, we observed significantly reduced nasal polyps and congestion symptoms in adults who had nasal polyps in two pivotal Phase III studies,” said Joseph Han, M.D., Chief of the Division of Rhinology and the Division of Allergy at Eastern Virginia Medical School and study investigator of the POLYP 1 and POLYP 2 trials. “Xolair provides a new option for treating these patients, who often have other respiratory and allergic conditions that may further worsen symptoms.”
The FDA’s approval is based on results from the Phase III POLYP 1 and POLYP 2 trials. Both trials showed that adult patients with nasal polyps who had an inadequate response to nasal corticosteroids and received Xolair had statistically significant greater improvement from baseline at Week 24 in Nasal Polyp Score (NPS) and weekly average Nasal Congestion Score (NCS) than patients who received placebo. The greater improvements in NPS and NCS in the Xolair group compared to the placebo group were observed as early as the first assessment at Week 4 in both studies. All patients received background nasal mometasone therapy during both the treatment period and a five-week run-in period. In POLYP 1 and POLYP 2, the mean change from baseline at Week 24 for Xolair compared to placebo were: NPS, -1.1 versus 0.1 (95% CI: -1.6, -0.7) and -0.9 versus -0.3 (95% CI: -1.1, -0.1); NCS, -0.9 versus -0.4 (95% CI: -0.8, -0.3) and -0.7 versus -0.2 (95% CI: -0.8, -0.2). POLYP 1 and POLYP 2 are the ninth and tenth Phase III trials for Xolair, respectively. Results from POLYP 1 and POLYP 2 were recently published in the Journal of Allergy and Clinical Immunology.
