What is being measured

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

  1. Trough Forced Expiratory Volume in 1 Second (FEV1) Change From Baseline to 24 Months

    Measurement over time (from baseline over the 24-month treatment period) and change from baseline to end of the treatment period.

    Measured: Baseline, 24 months

Secondary outcomes (2)
  1. Change From Baseline at 24 Months in Total Symptom Diary Score

    Subjects were required to keep a symptom diary throughout the entire trial period from the start of investigational medicinal product (IMP) administration in the washout period until the end of the treatment period. Assessment items included scores for shortness of breath, cough, and sputum, IMP compliance, use of salbutamol and respiratory symptom medications, and smoking status. Subjects recorded a score of between 0 and 3, with 0 indicating no symptoms and 3 indicating a high level of symptoms, for each domain.

    Measured: Baseline, 24 months

  2. Change From Baseline at 24 Months in St. George's Respiratory Questionnaire (SGRQ) Total Score

    The SGRQ is a self-administered questionnaire designed to measure and quantify the impact of chronic respiratory disease on health-related quality of life (QOL) and well-being in three domains: symptoms, activity, and impact on daily life. The SGRQ was completed by each subject prior to IMP administration at baseline and at Month 6, Month 12, Month 18, and Month 24 (end of treatment).

    A weighted score based on population norms for each dimension and total was evaluated. Scores were expressed as a percentage of overall impairment where 100 represented worst possible health status and 0 indicated best possible health status. Scores were calculated when less than 24% of the item scores were missing, otherwise the scores were set to missing. Where there were multiple answers for a question, the worst case was used.

    Measured: Baseline, 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing tetomilast (OPC-6535) in people with Chronic Obstructive Pulmonary Disease, run by Otsuka Pharmaceutical Co., Ltd. at 9 sites in 3 countries.

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 6 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 30 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in China, Japan, South Korea. 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. 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 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?

Yes. Results are posted in the registry (first posted 30 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Trough Forced Expiratory Volume in 1 Second (FEV1) Change From Baseline to 24 Months (time frame: Baseline, 24 months). 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 30 Apr 2021.
