Recruitment & Eligibility

• Status: Closed to Recruitment of Participants
• Sex: Not specified
• Target Recruitment: 0

Inclusion Criteria

Participant must be at least 6 years of age at the time of signing the informed consent.

Participants with the diagnosis of AFRS adapted from criteria by Bent and Kuhn.

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

Prior sino-nasal surgery(ies) for AFRS

Body weight =15 kg

Male and/or female Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

o A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies

Is not a woman of childbearing potential (WOCBP)

Is a WOCBP and agrees to use an acceptable contraceptive method as described in Appendix 4 (Section 10.4) of the protocol during the study (at a minimum until 12 weeks after the last dose of study intervention).

A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) on Day 1 before the first dose of study intervention.

If a urine test on Day 1 cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded

from participation if the serum pregnancy result is positive.

Capable of giving signed informed consent as described in Appendix 1 (Section 10.1) of the protocol which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. In countries where legal age of majority is above 18 years, a specific ICF must also be signed by the participant’s legally authorized representative. For adolescents (=12 to <18 years) and for children (=6 to <12 years), both the adolescent/child and the parent/legally authorized representative must sign the specific ICF/assent form

Exclusion Criteria

Patients with conditions/concomitant diseases making them non-evaluable at Visit 1 or for the primary efficacy endpoint such as:

Antrochoanal polyps.

Nasal septal deviation that would occlude at least one nostril.

Acute sinusitis, nasal infection or upper respiratory infection within 2 weeks prior to Visit 1 (patient can be rescreened after resolution of symptoms).

Ongoing rhinitis medicamentosa.

Eosinophilic granulomatous polyangiitis (Churg-Strauss syndrome), granulomatosis with polyangiitis (Wegener’s granulomatosis), microscopic polyangiitis, Young’s syndrome,

Kartagener’s syndrome or other dyskinetic ciliary syndromes, cystic fibrosis

Patients with nasal cavity malignant tumor and benign tumors (eg, papilloma, hemangioma, etc)

Known of fungal invasion into sinus tissue.

Diagnosed with, suspected of, or at high risk of endoparasitic infection, and/or use of antiparasitic drug within 2 weeks before the Screening Visit (Visit 1) or during the screening period.

Histories of human immunodeficiency virus (HIV) infection or positive HIV screen (antiHIV-1 and HIV-2 antibodies) serology at the Screening Visit (Visit 1).

Severe concomitant illness(es) that, in the Investigator’s judgment, would adversely affect the patient’s participation in the study. Examples include, but are not limited to participants with short life expectancy, participants with uncontrolled diabetes (hemoglobin A1c =9%), participants with cardiovascular conditions (eg, Class III or IV cardiac failure according to the New York Heart Association classification), severe renal conditions (eg, participants

on dialysis), hepato-biliary conditions (eg, Child-Pugh class B or C), neurological conditions (eg, demyelinating diseases), active major autoimmune diseases (eg, lupus, inflammatory bowel disease, rheumatoid arthritis, etc), other severe endocrinological, gastrointestinal, metabolic, pulmonary, or lymphatic diseases. The specific justification for participants excluded under this criterion will be noted in study documents (chart notes, electronic case report forms [eCRFs], etc).

Known or suspected history of immunodeficiency, including history of invasive opportunistic infections (eg, tuberculosis [TB], histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, and aspergillosis), despite infection resolution, or otherwise recurrent infections of abnormal frequency or prolonged duration suggesting an immune-compromised status, as judged by the Investigator.

Patients with active TB or non-tuberculous mycobacterial infection, or a history of incompletely treated TB will be excluded from the study unless it is well documented by a specialist that the patient has been adequately treated and can now start treatment with a biologic agent, in the medical judgment of the Investigator and/or infectious disease specialist. Tuberculosis testing would be performed on a country by country basis according to local guidelines if required by regulatory authorities or ethic boards.

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

History of malignancy within 5 years before Visit 1, except completely treated in situ carcinoma of the cervix, completely treated and resolved nonmetastatic squamous or basal cell carcinoma of the skin.
