What is being measured

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

  1. EORTC QLQ-C30

    European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) is a 30-item patient-reported questionnaire comprising five functional scales (physical, role, emotional, cognitive, and social functioning), three symptom scales (fatigue, nausea and vomiting, and pain), a global health status/quality-of-life scale, and six single-item symptom measures. Each scale or item score is linearly transformed to a range from 0 to 100 (minimum: 0; maximum: 100). Higher scores on the functional scales and the global health status/quality-of-life scale indicate better functioning or quality of life, whereas higher scores on the symptom scales and single-item symptom measures indicate greater symptom severity and therefore a worse outcome. Changes from baseline will be assessed at Weeks 6 and 8.

    Measured: Change from baseline to 6-week and 8-week

  2. EORTC QLQ-LC13

    European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer 13 (EORTC QLQ-LC13) is a 13-item lung cancer-specific patient-reported questionnaire used in conjunction with the EORTC QLQ-C30. It assesses lung cancer-related symptoms and treatment-related problems, including dyspnoea, coughing, haemoptysis, sore mouth, dysphagia, peripheral neuropathy, alopecia, and pain at specific sites. Scores for the dyspnoea scale and individual symptom items are linearly transformed to a range from 0 to 100 (minimum: 0; maximum: 100). Higher scores indicate greater symptom severity or treatment-related problems and therefore a worse outcome. Changes from baseline will be assessed at Weeks 6 and 8.

    Measured: Change from baseline to 6-week and 8-week

Secondary outcomes (3)
  1. NK cell percentage in peripheral blood

    Measured: Change from baseline to 8-week

  2. CD4+/CD8+ T cell in peripheral blood

    Measured: Change from baseline to 8-week

  3. total T cell, T-helper cell, T-suppressor cell and B-cell percentage in peripheral blood

    Measured: Change from baseline to 8-week

Questions about this trial

What is this clinical trial studying?

A study testing Lindera obtusiloba extract in people with Non Small Cell Lung Cancer, run by Jun-Yong Choi at 1 site in South Korea.

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 8 inclusion and 14 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 12 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

EORTC QLQ-C30 (time frame: Change from baseline to 6-week and 8-week). The study lists 2 primary outcomes in all. 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 12 Aug 2026.
