Participants will receive standard care regarding nail toxicity. This entails advice to keep nails trim and the provision of a nail oil to massage into the nail daily. Participants will also receive advice in relation to general healthy living.

Participants will receive the same standard care as the control arm, except for the nail drops. The participants will also receive Onicolife nail drops to be applied twice daily.

Nail Toxicity

The prescription free, CE (Conformité Européenne) marked product is for local application, and has a novel mode of action involving the modulation of mast cell action with the fatty acid amide, Adelmidrol ®. Mast cells are known to have a key role in the ability of the body to promote healing /repair and control tissue damage caused by chemo and radiotherapy. This includes damage to the nail and/ or nail matrix. OnicoLife ® thus helps to control inflammation and pain whilst antimicrobial action also provides antibacterial and antifungal support.

Onicolife nail drops

One dark colour of nail polish (deep burgundy/red) will be used in this study since this colour is considered more acceptable to many more women than a pure black coloured nail polish and hence, more likely to ensure compliance. No nail polish containing hardeners will be used since there is some evidence to suggest they can induce nail changes. As dark nail polish can stain the nail plate (and therefore mask any changes in nail pigmentation induced by chemotherapy), one clear base coat, two coats of coloured, and one clear top coat of polish will be required for each application. This standard of application is proposed as a gold standard for the prevention of nail staining and hypersensitivity reactions by an eminent podiatrist (Spalding, 2008).

Taxane Chemotherapy and Nail Toxicity in Women With Breast Cancer; Stage Two: Evaluation of Interventions

Evaluate nail interventions (nail polish + standard care Vs Onicolife drops + standard care Vs Standard Care only) that may prevent or minimise the occurrence and severity of nail problems measured using the NToX-G12 (Nail Assessment Scale).

Evaluate nail interventions (nail polish + standard care Vs Onicolife drops + standard care Vs Standard Care only) that may prevent or minimise the occurrence and severity of nail problems measured using Common Terminology Criteria for Adverse Events v3.0 (CTC-AE v3).

Evaluate any change in the patient's quality of life, in relation to nail problems occurring, as measured using the NToX-QoL (quality of life questionnaire).

Evaluate any change in the patient's quality of life, in relation to nail problems occurring, as measured using the EQ-5D-5L (quality of life questionnaire)

Assess collected data for any correlating relationship between nail grade severity (measured using NToX-G12 - outcome measure 1) and qualify of life (measured using NToX-QoL - outcome measure 3).
