Study summary

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.

Terms in these criteria, in plain language(28)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Baseline and Week 24

  2. 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.

    Time frame: Baseline and Week 24

Secondary outcomes

  1. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 28, 32, 40, 48, 52, and 60

  2. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  3. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  4. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 28, 32, 40, 48, 52, and 60

  5. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  6. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  7. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  8. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 52, and 60

  9. 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.

    Time frame: Baseline (prior to first dose) and Weeks 24 and 52

    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.

    Time frame: Baseline up to Week 24, and Baseline up to Week 60

  11. 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.

    Time frame: Baseline up to Week 60; assessment visits are at Weeks 4, 8, 12, 16, 20, 24, 28, 32, 40, 48, 52, and 60

  12. 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).

    Time frame: Baseline up to Week 60

  13. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 52, and 60

  14. 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.

    Time frame: Baseline and Weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 52, and 60
