Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
EORTC QLQ-C30
Time Frame: Change from baseline to 6-week and 8-week
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.
Change from baseline to 6-week and 8-week
EORTC QLQ-LC13
Time Frame: Change from baseline to 6-week and 8-week
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.
Change from baseline to 6-week and 8-week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
NK cell percentage in peripheral blood
Time Frame: Change from baseline to 8-week
Change from baseline to 8-week
CD4+/CD8+ T cell in peripheral blood
Time Frame: Change from baseline to 8-week
Change from baseline to 8-week
total T cell, T-helper cell, T-suppressor cell and B-cell percentage in peripheral blood
Time Frame: Change from baseline to 8-week
Change from baseline to 8-week
