About this study

Official title: An Open-label, Single-arm, Multicenter, Extension Study to Evaluate the Long-term Safety and Efficacy of CM310 in Patients With Chronic Rhinosinusitis With Nasal Polyps

This is an open-label, single-arm, multicenter, extension study to evaluate the long-term safety and efficacy of CM310 in patients with CRSwNP.

Being tested
CM310

What participants receive

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidences of TEAE, SAE and AESI related to CM310; Abnormalities in laboratory tests, physical examination, vital sign and 12-lead electrocardiogram.

    Incidences of TEAE, SAE and AESI related to CM310; Abnormalities in laboratory tests, physical examination, vital sign and 12-lead electrocardiogram.

    Measured: approximately 2 years

Secondary outcomes (12)
  1. Changes from baseline in total nasal polyp score (NPS) from both sides at each evaluation time point.

    The NPS score will be graded based on the nasal polyp size of both left and right nostrils described by nasal endoscopy by the study doctor nasal endoscopy. Each nostril is scored on a scale of 0-4, with the total score being the sum of both nostrils (0-8).

    Measured: approximately 2 years

  2. Changes from baseline in weekly average nasal congestion score (NCS) at each evaluation time point.

    The NCS scoring ranges from 0-3 points and is conducted separately on both left and right nostril. The higher score from either left or right side is taken as the NCS score on each day, and the total score is 3 points.

    Measured: approximately 2 years

  3. Changes from baseline in University of Pennsylvania Smell Identification Test (UPSIT) score at each evaluation time point.

    The UPSIT has a total of 40 questions and consists of 4 different booklets. The test patient will smell the odorant level after cutting the capsule with a nail or pencil and then choose an answer from 4 choices on each page. One score is counted if an odor is correctly selected, with a total score of 40 points. The lower the score, the more impaired the smell function.

    Measured: approximately 2 years

  4. Changes from baseline in sino-nasal outcome test-22 (SNOT-22) score at each evaluation time point.

    The SNOT-22 score is a specific scale for chronic rhinosinusitis and can evaluate the patient-reported outcome (PRO) and health-related quality of life (HRQoL) of patients suffering from chronic rhinosinusitis, with contents covering 22 dimensions related to quality of life. Each dimension is scored as 0-5, so with a total score of 110.

    Measured: approximately 2 years

  5. Changes from baseline in patient's nasal total symptom score (TSS) at each evaluation timepoint.

    The evaluation content of TSS includes three aspects: nasal congestion, loss of smell and running nose. Each aspect has a score of 0-3 with a total score of 0-9. The higher score indicates the more severe overall symptom.

    Measured: approximately 2 years

  6. Changes from baseline in Lund-Mackay score of sinus CT scan at each evaluation time point.

    Sinus CT scan evaluation includes Lund-Mackay scores and 3D volumetric measurement of the sinus, which are objective evaluation parameters commonly used to evaluate the severity of CRS.

    Measured: approximately 2 years

  7. Changes from baseline in three-dimensional sinus inflammation volume of sinus CT scan performed sat each evaluation time point.

    Sinus CT scan evaluation includes Lund-Mackay scores and 3D volumetric measurement of the sinus, which are objective evaluation parameters commonly used to evaluate the severity of CRS.

    Measured: approximately 2 years

  8. Changes from baseline in total scores of NPS and NCS in patients with a nasal polyp surgery history or complication with asthma at each evaluation time point.

    Measured: approximately 2 years

  9. Percentage of patients receiving rescue therapy.

    Measured: approximately 2 years

  10. Immunogenicity endpoint: generation of anti-drug antibodies (ADAs) and/or neutralizing antibodies (Nabs).

    Measured: approximately 2 years

  11. PD endpoint: Changes from baseline in eosinophils levels in plasma and nasal polyp biopsy samples at each evaluation time point.

    Measured: approximately 2 years

  12. PK endpoint: steady-state trough concentration (CtroughSS) of CM310.

    Measured: approximately 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CM310 in people with Chronic Rhinosinusitis With Nasal Polyps, run by Keymed Biosciences Co.Ltd at 3 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidences of TEAE, SAE and AESI related to CM310; Abnormalities in laboratory tests, physical examination, vital sign and 12-lead electrocardiogram. (time frame: approximately 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Nov 2024.
