PG2 Breast Cancer Evaluation in Adjuvant Medicine Study (PG2 BEAM)

June 15, 2026 updated by: PhytoHealth Corporation

PG2 Treatment for Reduction of Chemotherapy-Induced Toxicity and Encouraging Compliance With Chemotherapy Among Stage II/III Breast Cancer Patients Receiving Adjuvant Chemotherapy

Adjuvant chemotherapy usually is recommended after surgery for breast cancer patients who are at significant risk for disseminated disease. Chemotherapy has been demonstrated to reduce the risk of breast cancer recurrence. Anthracycline-based regimens, including doxorubin or epilubicin, are the breast cancer adjuvant chemotherapy standards of care. Fatigue has also been identified as the most problem for breast cancer patients under adjuvant chemotherapy. In the current study, it is aimed to show that PG2 (astragalus polysaccharides) treatment among stage II/III breast patients under adjuvant EC regimen in reduction of chemotherapy-induced toxicity and encouraging compliance with chemotherapy.

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.

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.
