– The Phase III POLYP 1 and POLYP 2 studies of Xolair in adults with chronic rhinosinusitis with nasal polyps (CRSwNP) with inadequate response to intranasal corticosteroids met both co-primary endpoints and key secondary endpoints –
– In both studies, Xolair showed a safety profile consistent with previous FDA-approved indications –
– CRSwNP impacts up to 4 percent of people worldwide, and the prevalence increases with age –
SOUTH SAN FRANCISCO, CA, USA I June 03, 2019 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced positive topline data from two Phase III multicenter studies evaluating Xolair® (omalizumab) for the treatment of adults with chronic rhinosinusitis with nasal polyps (CRSwNP) who have not adequately responded to intranasal corticosteroids. The POLYP 1 and POLYP 2 Phase III trials met both co-primary endpoints and key secondary endpoints. Xolair, an injectable biologic medicine designed to target and block immunoglobulin E (IgE), was shown to be well tolerated and the safety profile was consistent with that observed in previous studies in people with moderate to severe allergic asthma and chronic idiopathic urticaria.
“The results from these pivotal studies provided further support that IgE plays a role in inflammatory and respiratory conditions, and showed that Xolair reduced the size of nasal polyps and associated symptoms that impact these patients’ quality of life,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We plan to discuss these results with the FDA with the goal of bringing this new treatment option as soon as possible to people who do not experience relief with the current standard of care.”
The co-primary endpoints of POLYP 1 and POLYP 2 were change from baseline in Nasal Polyp Score (NPS) and change from baseline in average daily Nasal Congestion Score (NCS) over 24 weeks. Xolair demonstrated statistically significant and clinically relevant improvements in both of these co-primary outcomes. Patients enrolled in the study included those with and without a history of surgery.
Key secondary endpoints were met, including improvement in smell, post-nasal drip (posterior rhinorrhea score), runny nose (anterior rhinorrhea score) and the Sino-Nasal Outcome Test-22 (SNOT-22) health-related quality of life assessment.
CRSwNP is the inflammation of the nose and paranasal sinuses with the presence of nasal polyps on the lining of the nasal sinuses or nasal cavity.
Additional findings from these trials will be presented at an upcoming scientific congress.
About POLYP 1 and POLYP 2
POLYP 1 and POLYP 2 are replicate Phase III studies designed to determine the efficacy and safety of Xolair compared with placebo in adult patients with CRSwNP who have had an inadequate response to standard of care treatment. Both trials were randomized, multicenter, double-blind and placebo-controlled. POLYP 1 involved 138 patients, and POLYP 2 involved 127 patients. The primary outcomes for both trials were change from baseline in average daily Nasal Congestion Score at week 24, and change from baseline in Nasal Polyp Score to week 24. Patients in the studies were administered either Xolair or placebo by subcutaneous injection every two to four weeks.
About Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)
Chronic rhinosinusitis with nasal polyps (CRSwNP) is the inflammation of the nose and paranasal sinuses with the presence of noncancerous lesions (nasal polyps) on the lining of the nasal sinuses or nasal cavity. It is possible to have a single polyp or several and the size of the polyps can vary from microscopic to several centimeters. Symptoms can include nasal blockage/obstruction, nasal congestion, nasal discharge, facial pain/pressure and reduction in or loss of smell. CRSwNP is diagnosed by physical examination with endoscopy. The condition is associated with asthma and aspirin sensitivity.
Xolair is the only approved antibody designed to target and block immunoglobulin E (IgE). By reducing free IgE, down-regulating high-affinity IgE receptors and limiting mast cell degranulation, Xolair minimizes the release of mediators throughout the allergic inflammatory cascade.

Xolair U.S. Indication
Xolair for subcutaneous use is an injectable prescription medicine approved by the FDA to treat:
- Moderate to severe persistent asthma in patients six years of age or older whose asthma symptoms are not controlled by asthma medicines called inhaled corticosteroids. A skin or blood test is performed to see if a patient has allergies to year-round allergens.
- Chronic idiopathic urticaria (CIU; chronic hives without a known cause) in patients 12 years of age and older who continue to have hives that are not controlled by H1 antihistamine treatment.
Xolair is not used to treat other allergic conditions, other forms of urticaria, acute bronchospasm or status asthmaticus.
