What is being measured

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

  1. Annualized Rate of Moderate or Severe Chronic Obstructive Pulmonary Disease (COPD) Acute Exacerbations

    Moderate acute exacerbation of COPD (AECOPD) are defined as exacerbations that require either systemic corticosteroids (intramuscular, intravenous, or oral) and/or antibiotics. Severe AECOPD are defined as exacerbations requiring hospitalization or observation >24 hours in emergency department/urgent care facility. For both moderate and severe events to be counted as separate events, they are separated by at least 14 days. Annualized event rate are the total number of exacerbations that occure during the treatment period divided by the total number of participant-years treated.

    Measured: Baseline (Day 1) to 52 weeks

Secondary outcomes (20)

  1. Time to First Moderate or Severe Acute Exacerbation of COPD (AECOPD)

    The time to first moderate or severe exacerbation is defined as date of the first event minus randomization date +1. The median time to first severe exacerbation is derived from Cox regression model.

    Measured: Baseline (Day 1) to 52 weeks

  2. Annualized Rate of Severe Acute Exacerbations of COPD

    Severe AECOPD are defined as exacerbations requiring hospitalization or observation >24 hours in emergency department/urgent care facility. For severe events to be counted as separate events, they are separated by at least 14 days. Annualized event rate are the total number of exacerbations that occure during the treatment period divided by the total number of participant-years treated.

    Measured: Baseline (Day 1) to 52 weeks

  3. Change from baseline in pre-bronchodilator Forced Expiratory Volume in One Second (FEV1) at week 12

    The FEV1 is the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometer. Spirometry is performed after a wash out period of bronchodilators according to their action duration.

    Measured: Baseline (Day 1) to 12 weeks

  4. Change from baseline in pre-bronchodilator FEV1 at week 52

    The FEV1 is the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometer. Spirometry is performed after a wash out period of bronchodilators according to their action duration.

    Measured: Baseline (Day 1) to 52 weeks

  5. Change from baseline in pre-bronchodilator FEV1 at week 2,4,8,16,20,24,28,36,44,48

    The FEV1 is the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometer. Spirometry is performed after a wash out period of bronchodilators according to their action duration.

    Measured: Baseline (Day 1) to week 2,4,8,16,20,24,28,36,44,48

  6. Change from baseline in post-bronchodilator FEV1 at week 2,4,8,12,24,36,52

    The FEV1 is the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometer. Post-BD FEV1 refers to the spirometry performed within 15-30 minutes after administration of bronchodilator.

    Measured: Baseline (Day 1) to week 2,4,8,12,24,36,52weeks

  7. Change from baseline in Forced vital capacity（FVC）and forced expiratory flow (FEF) at 25%-75% at week 2,4,8,12,16,24,28,36,44,52

    FVC is defined as the volume of air (in liters) that can be forcibly blown out after full inspiration in the upright position. FEF is the amount of air (in liters) which can be forcibly exhaled from the lungs in the first second of a forced exhalation. FEF 25-75% is defined as the mean FEF between 25% and 75% of the FVC. Spirometry is performed after a wash out period of bronchodilators according to their action duration.

    Measured: Baseline (Day 1) to week 2,4,8,12,16,24,28,36,44,52weeks

  8. Change from baseline in Saint (St.) George's Respiratory Questionnaire (SGRQ) Total Score at week 52

    The SGRQ is a 50-item self-administered questionnaire designed to measure and quantify health status in adult participants with chronic airflow limitation and rate on electronic diary. Scores by dimension are calculated for 3 domains: symptoms, activity and impacts (psycho-social) as well as a total score. Global and domain scores range from 0 to 100, with 100 representing the worst possible health status and 0 indicating the best possible health status. Higher score indicates worse health status/heath related quality of life.

    Measured: Baseline (Day 1) to 52 weeks

  9. Percentage of Participants With SGRQ Improvement >=4 Points from baseline at Week 52

    A responder is defined as a participant with improvement from baseline in SGRQ total score at Week 52 by >=4 points. Participants with improvement <4 points or with missing values are considered as non-responders. The percentage of participants who achieved a clinically meaningful response in SGRQ total score (reduction [improvement] by >=4 points)/responders are reported.

    Measured: Baseline (Day 1) to 52 weeks

  10. Change from baseline in COPD assessment test (CAT) Total Score at each evaluation time point

    The COPD Assessment Test is a validated, short and simple patient completed questionnaire to measure the health status of patients with COPD. The CAT is an 8-item questionnaire suitable for completion by all patients diagnosed with COPD. When completing the questionnaire, subjects rate their experience on a 6-point scale, ranging from 0 (no impairment) to 5 (maximum impairment) with a scoring range of 0-40. Higher scores indicate greater disease impact.

    Measured: Baseline (Day 1) to week 2,4,8,12,24,36,44,52weeks

  11. Percentage of Participants With CAT Improvement >=2 Points from baseline at Week 52

    A responder is defined as a participant with improvement from baseline in CAT total score at Week 52 by >=2 points. Participants with improvement <2 points or with missing values are considered as non-responders. The percentage of participants who achieved a clinically meaningful response in CAT total score (reduction [improvement] by >=2points)/responders are reported.

    Measured: Baseline (Day 1) to 52 weeks

  12. Change from baseline in Evaluating Respiratory Symptoms (E-RS) total score at each evaluation time point

    The E-RS in COPD scale is a derivative instrument used to measure the effect of treatment on the severity of respiratory symptoms in stable COPD. E-RS: COPD RS-Total Score is derived based on weekly averages of daily assessed 11 respiratory symptom items contained in the 14-item EXACT questionnaire. The RS-Total score represent overall respiratory symptom severity, ranged from 0 to 40. The higher the score, more severe are the symptoms.

    Measured: Baseline (Day 1) to week 2,4,8,12,24,36,44,52weeks

  13. Percentage of Participants With E-RS Improvement >=2 Points from baseline at Week 52

    A responder is defined as a participant with improvement from baseline in E-RS total score at Week 52 by >=2 points. Participants with improvement <2 points or with missing values are considered as non-responders. The percentage of participants who achieved a clinically meaningful response in E-RS total score (reduction [improvement] by >=2points)/responders are reported.

    Measured: Baseline (Day 1) to 52 weeks

  14. Incidence of Adverse events (AEs)/treatment-emergent adverse events (TEAEs)

    An Adverse Event (AE) is defined as any untoward medical occurrence in a participant temporally associated with the use of study treatment, whether or not considered related to the study treatment. TEAEs are defined as AEs that developed or worsened in grade or became serious during TE period which is defined as the period from the time of first dose of study treatment until the last visit in the study.

    Measured: Baseline (Day 1) to 60 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing CM310 in people with Chronic Obstructive Pulmonary Disease, run by CSPC ZhongQi Pharmaceutical Technology Co., Ltd..

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 11 inclusion and 36 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: opening soon, as of the sponsor's last update on 14 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

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

What does this combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Clinical Trials Information Group officer (86-0311-69085587, ctr-contact@cspc.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Annualized Rate of Moderate or Severe Chronic Obstructive Pulmonary Disease (COPD) Acute Exacerbations (time frame: Baseline (Day 1) to 52 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06547333.

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?
