Effect and mechanism of YH0618 granule on chemotherapy- induced hair loss in patients with breast cancer: study protocol for a randomized, double-blind, multi-center clinical trial

Background: Hair loss is one of the most common side effects of chemotherapy, which can cause persistent negative emotions, further affecting therapeutic effects and reducing the quality of life. However, there is no clinically safe and effective methods to solve the problem at present. Our previous clinical and animal studies showed that a medicinal and edible decoction YH0618 could significantly promote hair growth in cancer patients after chemotherapy, without interfering with the anti-tumor effect of chemotherapy. Besides, the theory of Chinese Medicine believes “Essence of the kidney is reflected on the hair”. Therefore, this study will further explore the efficacy of YH0618 granule on chemotherapy-induced hair loss in patients with breast cancer by a randomized, double-blind, multi-center clinical trial and elucidate the potential mechanism from the aspect of kidney deficiency or renal dysfunction. Methods/Design: Eligible breast cancer patients who will start chemotherapy will be randomly divided into group A (YH0618 granule) and group B (placebo). The chemotherapeutic agents contains Taxanes or/and Anthracyclines, and chemotherapy regimen will last at least 6 cycles with every three weeks a cycle. Subjects assigned to group A will receive YH0618 granules two times a day (6 g each time), 6 days a week, mixing with 300 ml warm water from the first to the fourth chemotherapy cycle. Subjects in group B will receive the placebo granule in the same manner. The primary outcome is the time point of occurrence of hair loss reaching grade II assessed by WHO Toxicity Grading Scale, and objective indexes of hair quality and hair follicle recorded by a hair and scalp detector before the fifth chemotherapy. Secondary outcomes include changes of facial color and thumbnails color, grading of thumbnails ridging, assessment of quality life, fatigue, routine blood test, hepatic and renal function, and some medical indicators which can reflect kidney deficiency in Chinese Medicine. Discussion: This research is of great significance for the treatment of cancer and improving the quality of life of patients. The study may provide the most direct evidence for meeting clinical needs and lay a solid scientific foundation for later product development. Trial registration: The trial was registered on 14 December 2018 at Chinese Clinical Trial Registry: ChiCTR1800020107.
