Health-related Quality of Life-intervention in Survivors of Breast and Other Cancers Experiencing Cancer-related Fatigue Using Traditional Chinese Medicine: The HERBAL Trial

National University of Singapore80 enrolled

Overview

This study is a phase 2, randomized, double-blinded, placebo-controlled trial to evaluate the efficacy and safety of a Traditional Chinese Medicine decoction, the modified Xiang Bei Yang Rong Tang, in alleviating cancer related fatigue in cancer survivors.

Cancer-related fatigue (CRF) is a distressing, persistent and subjective sense of physical, emotional, or cognitive tiredness related to cancer or its treatment. Currently there is a lack of effective conventional pharmacological intervention for treating this condition. Traditional Chinese Medicine (TCM) could be alternative therapy for managing CRF. This study is a phase 2, randomized, double-blinded, placebo-controlled trial to examine the efficacy and safety of a TCM decoction, the modified Xiang Bei Yang Rong Tang (XBYRT) in alleviating CRF in cancer survivors. Study participants recruited from National Cancer Centre Singapore (NCCS) will be randomized to receive either the XBYRT or placebo decoction. Participants will take their assigned decoction daily for a duration of 8 weeks and will be assessed using patient reported outcome (PRO) questionnaires. PROs used are the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ 30) for QOL, the Multidimensional Fatigue Symptom Inventory Short Form (MFSI-SF) for fatigue and Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) Version 3 for cognitive abilities. The changes in scores measured by these assessment tools will be compared between the XBYRT intervention and placebo groups. Blood biomarkers such as inflammatory cytokines, mitochondrial DNA and oxidative stress markers will also be evaluated in the study participants. Additionally, adverse events or serious adverse events in participants will be monitored for safety. Results from this study will provide a better understanding on the role of TCM in managing CRF.

Outcomes

Primary Outcomes

Difference in Global Health Status (GHS) score

Difference in Global Health Status (GHS) score from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) between XBYRT interventional and placebo arms from baseline to 8 weeks after baseline. The GHS scale ranges in score from 0-100. A higher score represents a better quality of life

Time frame: 8 weeks from baseline

Secondary Outcomes

Difference in Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) scores

Difference in MFSI-SF scores between XBYRT interventional and placebo arms. THE MFSI-SF consists of 30 items and has 5 subscales, each with 6 items: general fatigue, physical fatigue, emotional fatigue, mental fatigue, and vigour. The MFSI-SF measures different dimensions of fatigue, which can be combined to obtain an overall score. A higher score represents worse fatigue (total score ranges from -24 to 96)

Time frame: 4, 8 and 10 weeks from baseline

Difference in Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog) version 3 scores

Difference in FACT-Cog V3 scores between XBYRT interventional and placebo arms. FACT-Cog v.3 will be used to assess subjective cognitive disturbances. These disturbances are assessed via 33 items in the domains of concentration, functional interference, mental acuity, memory, multitasking and verbal fluency (total score ranges from 0-148). A lower score represents worse cognitive function.

Time frame: 4, 8 and 10 weeks from baseline

Incidence of adverse events

Adverse events reported according to the Adverse events Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

Time frame: baseline, and 4, 8 and 10 weeks from baseline

Difference in EORTC QLQ-C30 version 3.0 Functional and Symptom scale scores
