About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Design, Phase III Clinical Study Evaluating the Efficacy and Safety of MG-K10 Humanized Monoclonal Antibody Injection in Patients With Chronic Rhinosinusitis With Nasal Polyps
This study aims to evaluate the efficacy and safety of MG-K10 humanized monoclonal antibody injection in the treatment of chronic rhinosinusitis with nasal polyps (CRSwNP). A total of 210 patients aged 18 to 75 years with bilateral CRSwNP are planned to be enrolled and randomized in a 1:1 ratio to receive either MG-K10 or placebo. During the first 24 weeks, participants will receive MG-K10 or placebo; they will subsequently enter a 28-week maintenance treatment period, during which the original placebo group will switch to receive MG-K10, and blinding will be maintained in both groups. MG-K10 is administered subcutaneously once every 4 weeks. Both groups will receive mometasone furoate nasal spray as background therapy from the run-in period through the end of the study. Following the treatment period, participants will be followed up for 8 weeks up to Week 60. The co-primary endpoints are the changes from baseline in Nasal Polyp Score (NPS) and Nasal Congestion Score (NCS) at Week 24; other symptoms, quality of life, safety, pharmacokinetics, pharmacodynamics, and immunogenicity will also be evaluated.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Bilateral Nasal Polyp Score (NPS)
Nasal endoscopy with central reading evaluates bilateral nasal polyp size. Each nostril is scored from 0 to 4, yielding a total bilateral Nasal Polyp Score (NPS) ranging from 0 to 8, where higher scores indicate larger polyp size. A negative change from baseline indicates improvement.
Measured: Baseline and Week 24
Change From Baseline in Nasal Congestion Score (NCS)
Participants record their previous day's nasal congestion severity daily on a scale from 0 to 3, where higher scores indicate more severe nasal congestion. The Nasal Congestion Score (NCS) baseline is typically calculated as the mean of the 7 days prior to randomization; if fewer than 4 days are recorded within those 7 days, the mean of the most recent 4 days of records prior to randomization is used. Post-baseline scores are calculated as the mean of at least 8 daily records within the 14 days prior to the scheduled visit. A negative change relative to baseline indicates improvement.
Measured: Baseline and Week 24
Secondary outcomes (14)
Change From Baseline in Bilateral Nasal Polyp Score (NPS) (Other Than Week 24)
Nasal endoscopy with central reading evaluates bilateral nasal polyp size. Each nostril is scored from 0 to 4, yielding a total bilateral Nasal Polyp Score (NPS) ranging from 0 to 8, where higher scores indicate larger polyp size. A negative change from baseline indicates improvement.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 28, 32, 40, 48, 52, and 60
Percentage of Participants With at Least a 1-Point Improvement From Baseline in Nasal Polyp Score (NPS)
Nasal endoscopy with central reading evaluates bilateral nasal polyp size. Each nostril is scored from 0 to 4, yielding a total bilateral Nasal Polyp Score (NPS) ranging from 0 to 8, where higher scores indicate larger polyp size; a negative change relative to baseline indicates improvement. The percentage of participants with a reduction of at least 1 point from baseline in NPS is calculated at each designated visit.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Percentage of Participants With at Least a 2-Point Improvement From Baseline in Nasal Polyp Score (NPS)
Nasal endoscopy with central reading evaluates bilateral nasal polyp size. Each nostril is scored from 0 to 4, yielding a total bilateral Nasal Polyp Score (NPS) ranging from 0 to 8, where higher scores indicate larger polyp size; a negative change relative to baseline indicates improvement. The percentage of participants with a reduction of at least 2 points from baseline in NPS is calculated at each designated visit.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Change From Baseline in Nasal Congestion Score (NCS) (Other Than Week 24)
Participants record their previous day's nasal congestion severity daily on a scale from 0 to 3, where higher scores indicate more severe nasal congestion. The Nasal Congestion Score (NCS) baseline is typically calculated as the mean of the 7 days prior to randomization; if fewer than 4 days are recorded within those 7 days, the mean of the most recent 4 days of records prior to randomization is used. Post-baseline scores are calculated as the mean of at least 8 daily records within the 14 days prior to the scheduled visit. A negative change relative to baseline indicates improvement.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 28, 32, 40, 48, 52, and 60
Percentage of Participants With at Least a 1-Point Improvement From Baseline in Nasal Congestion Score (NCS)
Participants record their previous day's nasal congestion severity daily on a scale from 0 to 3, where higher scores indicate more severe nasal congestion. The Nasal Congestion Score (NCS) baseline is typically calculated as the mean of the 7 days prior to randomization; if fewer than 4 days are recorded within those 7 days, the mean of the most recent 4 days of records prior to randomization is used. Post-baseline scores are calculated as the mean of at least 8 daily records within the 14 days prior to the scheduled visit. A negative change relative to baseline indicates improvement. The percentage of participants with a reduction of at least 1 point from baseline in NCS is calculated at each designated visit.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Change From Baseline in Total Symptom Score (TSS)
Total Symptom Score (TSS) comprises three items: nasal congestion, loss of smell, and rhinorrhea; scores for anterior rhinorrhea and posterior rhinorrhea are averaged first. Each item is scored 0-3, with a total score of 0-9, where higher scores indicate more severe symptoms. Baseline is the mean of the week prior to randomization, and post-baseline is the mean of the two weeks prior to the visit. If fewer than 4 days are recorded within the 7 days prior to randomization, baseline is the mean of the most recent 4 recorded days prior to randomization; at least 8 days of records are required within the 14 days prior to a post-baseline visit. The Week 24 assessment is a prespecified key secondary endpoint.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Change From Baseline in Loss of Smell (Hyposmia/Anosmia) Score
Participants daily assess the severity of loss of smell for the previous day. This score is identical to the smell item in the Total Symptom Score (TSS), ranging from 0-3, where higher scores indicate more severe symptoms. Baseline is the mean of the week prior to randomization, and post-baseline is the mean of the two weeks prior to the visit. If fewer than 4 days are recorded within the 7 days prior to randomization, baseline is the mean of the most recent 4 recorded days prior to randomization; at least 8 days of records are required within the 14 days prior to a post-baseline visit. The Week 24 assessment is a prespecified key secondary endpoint.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Change From Baseline in University of Pennsylvania Smell Identification Test (UPSIT) Score
A 40-item odor identification test, the University of Pennsylvania Smell Identification Test (UPSIT) awards 1 point for each correctly identified odor, with a total score ranging from 0 to 40, where higher scores indicate better olfactory function. The Week 24 assessment is a prespecified key secondary endpoint.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 52, and 60
Change From Baseline in Sinus Computed Tomography (CT) Lund-Mackay Score
Evaluated by central reading of sinus computed tomography (CT) scans. The bilateral Lund-Mackay score ranges from 0 to 24, where higher scores indicate more severe disease. Baseline values are based on central reading results of available CT scans prior to randomization/first dose that meet protocol quality and time-window requirements; if a qualified CT scan was completed during the screening or run-in period, repeated scanning at baseline is not required. The Week 24 assessment is a prespecified key secondary endpoint.
Measured: Baseline (prior to first dose) and Weeks 24 and 52
Percentage of Participants Receiving Rescue Treatment
Calculates the percentage of participants receiving rescue treatment with systemic corticosteroids or nasal polyp surgery due to worsening signs or symptoms of chronic rhinosinusitis with nasal polyps (CRSwNP). The cumulative percentage through Week 24 is a prespecified key secondary endpoint; rescue treatments during the subsequent treatment period and safety follow-up period are also recorded.
Measured: Baseline up to Week 24, and Baseline up to Week 60
Time to First Improvement of at Least 1 Point From Baseline in Nasal Polyp Score (NPS)
Time from baseline to the first occurrence of a reduction of at least 1 point from baseline in bilateral Nasal Polyp Score (NPS) observed at scheduled nasal endoscopy assessment visits.
Measured: Baseline up to Week 60; assessment visits are at Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60
Time to First Rescue Treatment
Time from baseline to the first administration of rescue treatment with systemic corticosteroids or nasal polyp surgery due to worsening of chronic rhinosinusitis with nasal polyps (CRSwNP).
Measured: Baseline up to Week 60
Change From Baseline in 22-Item Sino-Nasal Outcome Test (SNOT-22) Score
The 22-item Sino-Nasal Outcome Test (SNOT-22) is a participant-reported questionnaire with 22 items scored from 0 to 5 each, yielding a total score of 0 to 110, where higher scores indicate greater symptom severity and quality-of-life impact. The recall period covers the past 2 weeks. The Week 24 assessment is a prespecified key secondary endpoint.
Measured: Baseline and Weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 52, and 60
Change From Baseline in EuroQol 5-Dimension 5-Level Visual Analogue Scale (EQ-5D-5L VAS) Score
The EuroQol Visual Analogue Scale (EQ VAS) component of the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire records participant-rated health status on a scale from 0 to 100, where 0 represents the worst health imaginable and 100 represents the best health imaginable.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study aims to evaluate the efficacy and safety of MG-K10 humanized monoclonal antibody injection in the treatment of chronic rhinosinusitis with nasal polyps (CRSwNP). A total of 210 patients aged 18 to 75 years with bilateral CRSwNP are planned to be enrolled and randomized in a 1:1 ratio to receive either MG-K10 or placebo. During the first 24 weeks, participants will receive MG-K10 or placebo; they will subsequently enter a 28-week maintenance treatment period, during which the original placebo group will switch to receive MG-K10, and blinding will be maintained in both groups. MG-K10 is administered subcutaneously once every 4 weeks. Both groups will receive mometasone furoate nasal spray as background therapy from the run-in period through the end of the study. Following the treatment period, participants will be followed up for 8 weeks up to Week 60. The co-primary endpoints are the changes from baseline in Nasal Polyp Score (NPS) and Nasal Congestion Score (NCS) at Week 24; other symptoms, quality of life, safety, pharmacokinetics, pharmacodynamics, and immunogenicity will also be evaluated.

| Mometasone Furoate Nasal SprayMometasone furoate nasal spray administered as background therapy for all participants at 200 μg daily from the run-in period through study completion at Week 60: 2 actuations per nostril once daily, 50 μg per actuation. | Drug | MG-K10, Placebo |
Primary outcome
Change From Baseline in Bilateral Nasal Polyp Score (NPS)
Time frame: Baseline and Week 24
Nasal endoscopy with central reading evaluates bilateral nasal polyp size. Each nostril is scored from 0 to 4, yielding a total bilateral Nasal Polyp Score (NPS) ranging from 0 to 8, where higher scores indicate larger polyp size. A negative change from baseline indicates improvement.
Change From Baseline in Nasal Congestion Score (NCS)
Time frame: Baseline and Week 24
Participants record their previous day's nasal congestion severity daily on a scale from 0 to 3, where higher scores indicate more severe nasal congestion. The Nasal Congestion Score (NCS) baseline is typically calculated as the mean of the 7 days prior to randomization; if fewer than 4 days are recorded within those 7 days, the mean of the most recent 4 days of records prior to randomization is used. Post-baseline scores are calculated as the mean of at least 8 daily records within the 14 days prior to the scheduled visit. A negative change relative to baseline indicates improvement.
