Clinical Trial Summary

The aim of this study is to assess the efficacy of range of dermo-cosmetic products (hand/feet serum, nail strengthening solution nail strengthening solution, dissolving oil and gloves/slippers) based on natural products and designed for cancer patients)on bispecific Ac-induced skin and nail toxicity in MM patients treated with anti-CD3xGPRC5D bispecific antibodies.

The effects of supportive care products will be studied as a preventive measure in patients starting treatment with bispecific Ac and as a curative measure in patients undergoing treatment.

Patients will be able to apply the products directly at home according to the study schedule, and a skin and nail toxicity skin and nail toxicity will be performed each time the patient comes for administration of bispecific Ac. Follow-up will be for a total of 6 months (or less if progression occurs earlier), and patients will be asked to complete a quality-of-life questionnaire at protocol inclusion and after 1 month and 6 months of supportive care.
