EValuation of the Impact of a TOpical Lotion on Permanent Chemotherapy Induced Hair Disorders in Cancer Survivors

Overview

This study aims to evaluate the Impact of a topical Lotion, CG428, on permanent chemotherapy induced hair and scalp disorders in Cancer survivors. This is a double-blind, single center, randomized, controlled trial in breast cancer survivors. Hair condition and parameters of 61 breast cancer survivors who were previously included in DERMA study (a prospective cohort study to assess appearance changes due to breast cancer treatment completed in July, 13th,2013) will be assessed. 1. Patients whose hair parameters are below the baseline as measured before the start of the chemotherapy or 2. who complain from incomplete hair regrowth will be eligible to participate in the randomized controlled trial. Patients who agree to participant in the study will be randomly assigned to two parallel arms (Arm 1: CG428/ Arm 2: Placebo). Patients will self-administer the study product or placebo twice per day (morning, evening) for 6 months, for the efficacy assessment. Primary endpoint was recovery of hair thickness 6 months after intervention as assessed using Folliscope 4.0. Secondary endpoints included hair density at 6 months after intervention, distress due to chemotherapy induced alopecia, scalp skin parameters (water and sebum). Patient-reported hair quality improvement, body image and quality of life, and time to first visible improvement based on global photographs of hair and nails.

The research team at Cancer Education Center at Samsung Comprehensive Cancer Center has studied CIA and its impact on distress and psychosocial well-being since 2008. We found that more than half of the breast cancer patients experienced higher distress due to CIA, during cancer treatment, and this distress was strongly associated with negative body image, overall health status, and psychosocial well-being. In a recent prospective cohort study, we assessed skin and hair change patterns before, during and 6 months after chemotherapy in 61 volunteers. We found that the majority of the patients still experienced CIA at 6 months after completion of chemotherapy. Actually, hair diameter at 6th month after chemotherapy had not recovered to baseline level. Permanent chemotherapy-induced alopecia, defined as absent or incomplete hair regrowth at ≥6 months post-chemotherapy, was reported from 53 to 74%. Like CIA, permanent CIA also lacks recognition and has been underserved regardless of patients' needs. The first botanical blend Legacy Healthcare developed and patented is Cellium. Cellium is composed of 4 botanicals (Allium cepa L., Citrus limon L., Theobroma cacao L., Paullinia cupana). The first product derived from Cellium is a topical lotion for male and female alopecia, CG210. Based on the safety and efficacy data, the EMA (European Medicines Agency) has considered CG210 eligible for a European centralized herbal medicine registration. CG428 is the second product derived from Cellium. CG428 contains the exact same ingredients as CG210, in a different dosage. Legacy Healthcare have conducted a pilot studies with CG428 in Japan. The trial included female cancer survivors experiencing permanent/persistent CIA for more than 12. Based on the results, several cancer treatment centers in Japan have started to recommend the product on a compassionate basis.We therefore hypothesize that the investigated topical lotion may mitigate the impact of protracted or permanent CIA in cancer survivors by restoring a normalized apoptotic process of hair follicular cells and reducing the acute, as well as chronic inflammation in the scalp, two issues that may remain unsettled following anticancer treatment.
