About this study

The primary objective of this study is to evaluate the efficacy of PG2 concurrent with concurrent chemoradiation therapy (CCRT) for relieving fatigue among locally advanced esophageal cancer patients who are under preoperative chemoradiation therapy at curative setting. This study will be designed to compare the fatigue status between two study arms patients under CCRT.

The secondary objective is to assess the efficacy of PG2 to improve the quality of life of patient during CCRT. Also, the investigators try to determine the effect of PG2 on tumor response post CCRT, disease free survival (DFS) and overall survival (OS) of patients by comparing the above outcome between the two study arms.

The mechanism of immunomodulatory of PG2 and tumor response, DFS and OS for patients with esophageal cancer treated with preoperative CCRT concurrent with or without PG2 will be investigated in add-on study.

Read the detailed description

It's randomized, open-label study. Locally advanced esophageal cancer patients who give consent to participate in this study and meet all other inclusion and exclusion criteria will be eligible to enroll into this study. The eligible patients will be randomized into one of two study arms: 1) the CCRT- PG2 arm; and 2) the CCRT alone arm. All eligible patients will receive the standard preoperative CCRT during study period and standard surgery 6 weeks after completion of radiation therapy.

The primary objective of this study is to evaluate the efficacy of PG2 concurrent with CCRT for relieving fatigue. Patient's fatigue status will be measured by the BFI-T.

The secondary objective is to assess the efficacy of PG2 to improve the quality of life of patient during CCRT. Patients' quality of life will be assessed by the Functional Assessment of Cancer Therapy- General (FACT-G7 v.4). Patients' appetite will be assessed by VAS appetite score. The effect of PG2 on tumor response post CCRT, DFS and OS of patients will also be evaluated.

Peripheral blood samples and tumor biopsy samples will be collected from all subjects at screening period, during CCRT and post CCRT period to perform Immune biomarker assessment in the add-on study.

  • Astragalus Polysaccharides 500 mgDrug

    Also called PG2 Lyo. Injection 500 mg

    PG2 Lyo. Injection 500 mg will be given on 1 week before CCRT (Week 1, PG2 Lyo. Injection 500 mg, b.i.w), during CCRT (Week 2-6, PG2 Lyo. Injection 500 mg, t.i.w for 5 weeks), and after CCRT (Week 7-8, PG2 Lyo. Injection 500 mg, t.i.w for 2 weeks)

What is being measured

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

  1. Fatigue by the Brief Fatigue Inventory-Taiwanese Form

    The Brief Fatigue Inventory (BFI) has been shown to have good reliability of fatigue measurement. This instrument consists of a one-page fatigue assessment tool that contains nine items, each measuring the severity of fatigue on a 0-through-10 scale. The first three items assess current level of fatigue, and worst and usual fatigue in the preceding 24 hours. Six items assess the extent to which fatigue has interfered with different aspects of life, such as work or social relations, during the preceding 24 hours. The BFI score is calculated from the mean of completed items.

    Measured: Through 12 weeks

Secondary outcomes (6)
  1. Quality of life by the Functional Assessment of Cancer Therapy-General (FACT-G7 v.4)

    FACT-G7, a rapid version of the Functional Assessment of Cancer Therapy-General (FACT-G) which is one of most validated assessment tools to evaluate health related qulaity of life (HRQoL) among cancer patients. It is a 27-item instrument containing four subscales: physical well-being (PWB), functional well-being (FWB), social/family well-being (SWB), and emotional well-being (EWB) on 0-4 scale with a recall period of the past 7 days. The scores of these items must be reversed, and then summed to a total, which is the subscale score. The higher score is presented as the better quality of life.

    Measured: Through 12 weeks

  2. Visual Analog Score for appetite

    Visual Analog Score for appetite is a single-item scale will be used to measure by A 10-cm vertical line anchored with the number 0 to indicate "no appetite" and number 10 to indicate "worst possible appetite."

    Measured: Through 12 weeks

  3. Tumor response be evaluated by RECIST 1.1, irRECIST and Pathological response.

    Measured: Week 11 and Week 12

  4. Disease free survival

    Disease free survival (DFS) is defined as the time from initiation to relapse or death, whichever occurred first.

    Measured: 2 years after the take-off day of the last patient

  5. Overall survival in locally advanced esophageal cancer patients with PG2 treatment under preoperative chemoradiation therapy

    Overall survival (OS) is defined as the time from initiation to death of any cause.

    Measured: 2 years after the take-off day of the last patient

  6. The change of of biomarkers (inhibitory immune factors, dendritic cells makers, tumor-associated macrophages, immune-regulatory markers and oncogenic-mediated immune markers) will be combined to report the immune profile.

    Measured: Through 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Astragalus Polysaccharides 500 mg in people with Cancer-related Fatigue and Survival, run by PhytoHealth Corporation at 4 sites in Taiwan.

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 7 inclusion and 11 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 4 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Taiwan. 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?

Fatigue by the Brief Fatigue Inventory-Taiwanese Form (time frame: Through 12 weeks). 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 4 Jun 2025.
