Data from Dupixent clinical trials have shown that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in atopic dermatitis, asthma and chronic rhinosinusitis with nasal polyposis (CRSwNP
In June 2019, the FDA approved Dupixent for use with other medicines to treat chronic rhinosinusitis with nasal polyposis (CRSwNP
) in adults whose disease is not controlled.
Etokimab, previously referred to as ANB020, is an antibody that potently binds and inhibits the activity of interleukin-33, or IL-33, a pro-inflammatory cytokine that multiple studies have indicated is a central mediator of atopic diseases, which AnaptysBio believes is broadly applicable to the treatment of atopic inflammatory disorders, such as atopic dermatitis, eosinophilic asthma, chronic rhinosinusitis with nasal polyps, or CRSwNP
, and potentially other allergic conditions.
The US Food and Drug Administration (FDA) has granted approval to United States-based Regeneron Pharmaceuticals (NASDAQ: REGN) and France-based Sanofi for Dupixent (dupilumab) intended to treat adults with nasal polyps accompanied by chronic rhinosinusitis (CRSwNP
), it was reported yesterday.
Food and Drug Administration has approved Dupixent, dupilumab, for use with other medicines to treat chronic rhinosinusitis with nasal polyposis, CRSwNP
, in adults whose disease is not controlled.
South San Francisco, CA -- June 2, 2019 -- 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[R] (omalizumab) for the treatment of adults with chronic rhinosinusitis with nasal polyps (CRSwNP
) who have not adequately responded to intranasal corticosteroids.
6 percent had CRS with known nasal polyps (CRSwNP
It was shown that TSLP mRNA level expressed in nasal polyp epithelial cells is remarkably increased in patients with CRSwNP
. Furthermore, the expression levels of TSLP receptors in mucosal epithelial cells and subepithelial inflammatory cells were significantly increased in CRSwNP
and CRS patients without nasal polyps, indicating a potential role of TSLP in the pathogenesis of CRS.

Duration and severity of both AR and NAR were classified according to Allergic Rhinitis and its Impact on Asthma (ARIA) recommendations ; (c) rhinitis sicca, in patients referring the subjective sensation of "dry nose," coupled with visible dry nasal mucosa and atrophic nasal turbinates and Sjogren's syndrome ; (d) chronic rhinosinusitis with (CRSwNP
) and without (CRSsNP) nasal polyps, in cases of nasal blockage, nasal drip, facial pain, reduction of smell, associated to endoscopic nasal signs of polyps, mucopurulent discharge, and/or mucosal edema, according to European Position Paper on Rhinosinusitis and Nasal Polyps .
A decreased ratio of Treg to effector T cells can be appreciated in the inflamed nasal mucosa, as shown in adults with seasonal allergic rhinitis and, regardless of the allergic status, in those with CRS with nasal polyps (CRSwNP
) or without nasal polyps (CRSsNP) [110, 111].
