详细描述
The objective of this study is to assess the efficacy of weekly PG2 regimen as a complementary treatment for patients with recurrent unresectable (local or regional) or metastatic breast cancer who experienced moderate to severe fatigue while receiving chemotherapies. The primary endpoint is to examine whether PG2, compar ed with placebo, can successfully reduce patients' fatigue (observed via prorated area under the curve [AUC] for the Brief Fatigue Inventory [BFI] scores) when primed with PG2 for 8 weeks during their chemotherapy. The other efficacy endpoints including th e time course change of patient reported BFI, fatigue improvement response rate (fatigue improvement response is defined as those with at least 10% reduction from baseline in the total BFI scores) after 8 weeks, self perceived improvement, hematological improvement, health related quality of life, and safety profiles will also be assessed between treatment arms and compared with the baseline.

研究组 & 干预措施
PG2 treatment group
500 mg PG2 injection will be administered to this group once per week for 8 weeks.
干预措施: PG2 Lyo. Injection 500mg (Drug)
Placebo-controlled group
Placebo injection will be administered to this group once per week for 8 weeks.
干预措施: Placebo 0.9% normal saline (Drug)
结局指标
主要结局
Prorated AUC for the global BFI score
时间窗: 8 weeks
The prorated AUC for the global BFI score (average scores of 9 items), usual fatigue (item2) and worst fatigue (item 3) will be compared between PG2 and the placebo arms at the end of the study.
次要结局
- Fatigue improvement response rate (FIRR)(8 weeks)
