Long-term Safety and Efficacy Evaluation of Lunsekimig in Adult Participants With Chronic Rhinosinusitis With Nasal Polyps (CRSwNP) Who Completed a Previous Lunsekimig CRSwNP Study

Phase 2

Recruiting

• Conditions: Chronic Rhinosinusitis With Nasal Polyps
• Interventions: Drug: lunsekimig; Drug: Mometasone furoate nasal spray (MFNS)

• Registration Number: NCT06914908
• Lead Sponsor: Sanofi

Brief Summary

This is a single-arm extension study to investigate the long-term safety, tolerability, and efficacy of lunsekimig in adult participants with inadequately controlled CRSwNP who have completed a previous lunsekimig CRSwNP clinical study (also referred to as the parent study ACT18207).

The study duration will be up to approximately 56 weeks per participant, 52 weeks of treatment period, and 4 weeks of follow-up.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 64

Inclusion Criteria

• Participants who have completed the treatment period and the follow up period in CRSwNP lunsekimig parent study, including EOS visit, as per protocol.
• Participants receiving therapy with intranasal mometasone furoate nasal spray (MFNS).
• Participants who are able and willing to participate in this extension study, and to comply with requested study visits and procedures.

Exclusion Criteria

Participants are excluded from the study if any of the following criteria apply:

• Prior hypersensitivity reaction to lunsekimig or to any of the excipients used in the presentation or in preparation for administration of lunsekimig, or other allergy that, in the opinion of the Investigator, contraindicates participation in the study.
• Concurrent participation in any clinical study other than the parent study, including non-interventional studies.
• Participants who, during their participation in the parent study, developed an adverse event (AE) or a serious adverse event (SAE) deemed related to lunsekimig, which in the opinion of the Investigator could indicate that continued treatment with lunsekimig may present an unreasonable risk for the participant NOTE: The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial

Arm && Interventions

Group	Intervention	Description
Lunsekimig	lunsekimig	Participant will receive lunsekimig subcutaneous (SC) every 4 weeks and intranasal mometasone furoate nasal spray (MFNS) daily for 52 weeks.

Primary Outcome Measures

Name	Time	Method
Incidence of participants with treatment-emergent adverse events (TEAEs) including	From baseline to end of study (approximately 56 weeks)

Secondary Outcome Measures

Name	Time	Method
Change in SNOT-22 total score	From the parent study baseline to Week 52	The SNOT-22 is a 22-item health-related outcomes assessment. The 22-question SNOT-22 is scored as 0 (no problem) to 5 (problem as bad as it can be) with a total range from 0 to 110 (higher scores indicate poorer outcomes).
Change in rhinosinusitis visual analog scale (VAS)	From the parent study baseline to Week 52	The VAS for rhinosinusitis is used to evaluate the total severity. The participant is asked to indicate along a 10 centimeter straight horizontal line (VAS) the answer to the question: "How troublesome are your symptoms of your rhinosinusitis". The VAS ranks from 0 (Not troublesome) to 10 (Worst thinkable troublesome) and is measured in centimeters
Anti-drug antibodies (ADA) against lunsekimig	From baseline to end of study (approximately 56 weeks)
Change in University of Pennsylvania Smell Identification Test (UPSIT) score	From the parent study baseline to Week 52	The UPSIT test is a rapid and easy-to-administer method to quantitatively assess human olfactory function. The test consists of four booklets, each containing 10 odorants with one odorant per page. Above each odorant strip is a multiple-choice question with four alternative words to describe the odor. Score depends on the amount of answers out of 40 possible correct answers.
Serum lunsekimig concentrations	From baseline to end of study (approximately 56 weeks)
