Background and study aims
Breast irradiation (radiotherapy) after breast surgery is a standard of care for about half of the patients with breast cancer. Localized radiotherapy is delivered daily during a few weeks to the breast area. During this period, the irradiated skin can be damaged. Mild redness is the first sign to appear generally within few hours of radiation exposure, even if the most common skin reactions occur about 10–14 days after the beginning of the therapy and may include symptoms like skin swelling, dryness, burning, itching, tenderness, change in skin colour and skin lesions. Such symptoms disappear after the radiation therapy has finished. However, sometimes skin reactions are so intense that the patient is obliged to discontinue radiotherapy. The application during radiotherapy of hydrating creams on the irradiated skin area can help reducing the risk of severe skin damage. The product used in this study is a cream containing hylauronic acid, a natural component of the skin with hydrating and cicatrizing properties. This product is already used for the treatment of skin wounds, including chronic wounds like leg ulcers. The aim of this study is to find out whether twice daily application (morning and evening) of the cream with hyaluronic acid before, during and after radiotherapy, is able to reduce the severity of skin damage.
Who can participate?
Women aged 18 years and over who have undergone surgery for breast cancer and are scheduled for radiotherapy
What does the study involve?
Participants are randomly allocated to receive either the test cream or a neutral cream (the same cream without hyaluronic acid). The occurrence and the intensity of skin reactions are assessed both by the responsible physician and by means of an instrument (spectrophotometer) that can measure exactly the intensity of the colour of the irradiated skin and depict any change that occurred during the study as a consequence of the radiotherapy. Moreover, any other discomfort caused by the radiotherapy and its impact on daily life or any side effects of the applied cream are reported during the study period. Participants attend a maximum of 9 visits at the clinical site where the radiotherapy is delivered. Also, participants have to avoid the application on the irradiated skin area of any other product (including cosmetic products) and have to avoid exposure of the area to sun/sunbed during the whole study period. The patients under chemotherapy or who are under treatment with corticosteroids or other drugs known to or suspected of compromising the immune system (immunosuppressive therapy) are not allowed to participate. Patients who are allergic to the test cream or to one of its components should not participate in the study. If an allergic reaction develops during the study, the treatment with the cream has to be stopped. However, the radiotherapy can be continued, based on the opinion of the responsible physician.
What are the possible benefits and risks of participating?
The prevention or reduction in the intensity of the skin reaction generally experienced during and after radiotherapy are potential benefits for study participants. Possible risks include the occurrence of eczema, allergy, and hypersensitivity reactions to the tested creams. Severe reactions to the test cream have been very rarely reported.

| Scientific title | Mono-centre, prospective, placebo-controlled, double-blind, in parallel groups randomized clinical trial to evaluate the effectiveness of hyaluronic acid 0.2% cream for the prevention of skin toxicity in breast cancer patients treated with post-operative radiotherapy |
| Study objectives | To demonstrate the superiority of HA 0.2% cream in reducing the incidence of Grade ≥ 2 radiodermatitis, as compared to a neutral comparator (placebo) cream, when daily applied starting 2 weeks before local radiotherapy (LRT), during the LRT period until 2 weeks after the end of LRT. |
| Ethics approval(s) | Comitato Etico del Cantone Ticino, Bellinzona, Ticino-Switzerland, 22/10/2018 |
| Health condition(s) or problem(s) studied | Radiodermatitis |
| Intervention | The tested Investigational Product HA 0.2% cream, or Ialuset® cream, is a CE-marked medical device, classified as Class IIb, available as 100 g tubes. The neutral comparator (placebo) cream is physically and visually indistinguishable from the test. Adult female subjects having undergone curative surgery for unilateral stage I-III breast cancer and being scheduled for adjuvant LRT with conventional fractionation or hypofractionation at the investigation site, will be enrolled in the trial after having given written informed consent. According to a pre-established randomization sequence, the subjects will be treated daily with either HA 0.2% cream or neutral comparator cream, for 2 weeks before starting LRT up to 2 weeks after the end of a 6-week LRT (10 weeks of cream treatment) or 3-week LRT if hypofractionated schedule [15 fractions] (7 weeks of cream treatment in total). Patients will apply the cream twice daily, every 12 hours, with a dose sufficient to uniformly cover with a thin layer the whole cutaneous irradiated area (breast or chest wall). A wash out period of at least 6 hours has to be observed between the cream application and the irradiation. During the study participants attend a maximum of 9 control visits, always at the clinical site where the radiotherapy is delivered, to follow up treatment performance and tolerability. |

| Primary outcome measure | Proportion (%) of patients developing skin reactions (radiodermatitis) of Grade ≥ 2, as assessed by the Investigator according to the RTOG score, at the end of the LRT period |
