Taiwan66 participantsStarted 2026-05-27

Plain-language summary

Astragalus polysaccharides (APS), acting as an immunomodulator, is known to modulate the tumor microenvironment and inhibit tumor growth and progression, thereby suggesting potential as an adjuvant cancer therapy to improve treatment outcomes. PG2 (APS Injection) has completed a clinical trial (Protocol name: PG2 Treatment for Reduction of Chemotherapy-Induced Toxicity and Encouraging Compliance with Chemotherapy among Stage II/III Breast Cancer Patients Receiving Adjuvant Chemotherapy , NCT03314805, hereinafter called the parent trial) aimed to show that PG2 treatment among stage II/III breast patients under adjuvant Epirubicin and cyclophosphamide (EC) regimen in reduction of chemotherapy-induced toxicities and encouraging compliance with chemotherapy. This study will further explore whether the addition of PG2 can delay cancer recurrence or metastasis, thereby conferring substantial survival benefits for early breast cancer patients with adjuvant chemotherapy by retrospectively collecting recurrence, metastasis, and survival information from patients enrolled in the parent trial.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
