Zi Huangjing^TM Preparation Relieves Cancer-Related Fatigue During Chemotherapy: A Prospective Single-Arm Multicenter Clinical Trial

  Objective  To primarily explore the efficacy of Zi Huangjing^TM preparation in patients with cancer-related fatigue (CRF) during chemotherapy.

  Methods  This study was designed as a prospective, single-arm, multicenter clinical trial. According to the plan of the study, patients with malignant tumors who had received at least one cycle of chemotherapy and had moderate-to-severe CRF (Piper Fatigue Scale score≥4) were enrolled. All the enrolled patients took Zi Huangjing^TM preparation (2.1 g, twice a day) every day during the two subsequent cycles of chemotherapy and were followed up. During the period, the enrolled patients independently completed the Piper Fatigue Scale and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) scale, and part of their biochemical and immunological indicators were measured at the baseline, before the second cycle of chemotherapy (day 21), and before the third cycle of chemotherapy (day 42). The primary endpoint was the change in Piper Fatigue Scale scores between the baseline and day 42.

  Results  Eventually, 47 patients completed the entire study. After treatment, the mean score of the Piper Fatigue Scale assessed before the third cycle of chemotherapy (day 42) was 3.21±1.67, which was significantly lower than that at baseline (5.89±1.36) (P=0.000), and the patients’ CRF was significantly improved. In terms of quality of life, the patient's global quality of life, physical functions, role function, emotional function, cognitive function, and social function were significantly improved. In terms of symptom management, the patient's symptoms, such as fatigue, nausea and vomiting, insomnia, and appetite loss also significantly improved. No severe adverse reactions (grades 3 and 4) occurred during the observation period of this study. After evaluation, the adverse reactions that the patients actually had were considered to be related to chemotherapy, but unrelated to Zi Huangjing^TM preparation.

  Conclusion  According to our preliminary investigation, Zi Huangjing^TM preparation is safe and has the potential therapeutic effect of improving CRF in cancer patients during chemotherapy. However, further larger-scale randomized controlled clinical studies are needed to confirm the efficacy of Zi Huangjing^TM in improving CRF.
