Dupilumab in Allergic Fungal Rhinosinusitis (AFRS)

• Status: Recruiting
• Trial end date: 2023-11-21
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objective:

To evaluate the ability of dupilumab to reduce the need for rescue therapy with systemic corticosteroids (SCS) or surgery of AFRS in patients with AFRS who previously have had surgery for AFRS

Secondary Objectives:

To evaluate the efficacy of treatment with dupilumab to reduce sinus opacification in a population with allergic fungal rhinosinusitis (AFRS) To assess the efficacy of dupilumab to reduce the need for rescue treatments To evaluate the efficacy of treatment with dupilumab in improving symptoms in AFRS To evaluate the efficacy of dupilumab to reduce nasal polyp formation in patients with AFRS To evaluate the efficacy of dupilumab in improving overall symptom severity and quality of life in AFRS To evaluate the efficacy of dupilumab in improving sense of smell in patients with AFRS To explore the effect of dupilumab as assessed by three-Dimensional CT volumetric measurement of the paranasal sinuses To evaluate the safety and tolerability of dupilumab when administered to patients with AFRS To evaluate the pharmacokinetics (PK) of dupilumab in patients with AFRS To characterize the effect of dupilumab on total IgE and specific IgE To assess immunogenicity to dupilumab in patients with AFRS

Criteria

Inclusion criteria :

Participant must be at least 6 years of age (or the minimum legal age for adolescents in the country of the investigational site) at the time of signing the informed consent.

Participants with the diagnosis of AFRS adapted from criteria by Bent and Kuhn (meeting all):

• IgE mediated inflammatory response to fungal hyphae (specific IgE serology or skin test) Evidence of sensitization to fungus by skin testing (at screening or documented historical positive skin test in the previous 12 months), or positive fungal-specific IgE in serum at screening.

• Nasal polyposis confirmed by nasal endoscopy at screening.

• Characteristic CT signs to be performed during screening period and can include any of the below signs as assessed by central reader:

• hyperdensities

• bony demineralization

• bone erosion of sinus

• Eosinophilic mucin/mucus without fungal invasion into sinus tissue (identified within 5 years prior to screening or at screening) with or without positive fungal stain

AFRS patients with the following:

• An endoscopic NPS of at least 2 out of 4 for unilateral polyps or 3 out of 8 for bilateral polyps at Visit 1 (central reading) and Visit 2 (local reading) and,

• Sinus opacification in CT scan with an LMK score of 9 for patients with unilateral polyps or 12 for patients with bilateral polyps during screening period and,

Prior sino-nasal surgery(ies) for AFRS.

Body weight ≥15 kg

Exclusion criteria:

• Patients with nasal conditions/concomitant nasal diseases making them non-evaluable at Visit 1 or for the primary efficacy

• Nasal cavity malignant tumor and benign tumors.

• Known of fungal invasion into sinus tissue.

• Severe concomitant illness(es) that, in the investigator's judgment, would adversely affect the patient's participation in the study

• Active tuberculosis or non-tuberculous mycobacterial infection, or a history of incompletely treated tuberculosis unless documented adequately treated.

• Diagnosed active endoparasitic infections; suspected or high risk of endoparasitic infection

• Known or suspected immunodeficiency

• Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, or antifungals within 2 weeks before the Screening Visit 1 or during the screening period.

• History of systemic hypersensitivity or anaphylaxis to dupilumab or any of its excipients.

• Participation in prior dupilumab clinical study or have been treated with commercially available dupilumab.

• Patients who are treated with intranasal corticosteroid drops; intranasal steroid emitting devices/stents; nasal spray using exhalation delivery system, such as Xhance™, during screening period.

• Patients who are on intranasal corticosteroids (INCS) spray unless they have received stable dose for at least 4 weeks prior to Visit 1.

• Patients who have undergone sinus intranasal surgery (including polypectomy) within 6 months prior to Visit 1.

• Patients who have taken:

• Biologic therapy/systemic immunosuppressant to treat inflammatory disease or autoimmune disease within 5 half-lives prior to Visit 1

• Any investigational mAb within 5 half-lives prior to Visit 1

• Anti-IgE therapy (omalizumab) within 4 months prior to Visit 1.

• Treatment with a live (attenuated) vaccine within 4 weeks prior to Visit 1

• Leukotriene antagonists/modifiers unless patient is on a continuous treatment for at least 30 days prior to Visit 1.

• Initiation of allergen immunotherapy within 3 months prior to Visit 1 or a plan to begin therapy or change its dose during the screening or treatment period.

• Patients received SCS during screening period.

• Either intravenous immunoglobulin therapy and/or plasmapheresis within 30 days prior to Screening Visit (Visit 1).
