About this study
Official title: Evaluation of a Range of Dermo-cosmetic Products to Treat Skin and Nail Toxicity Linked to Bispecific Anti-GPRC5D Bispecific Antibodies in Multiple Myeloma Patients". Myeloma.
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
dermo-cosmetic productOther
For patients in the preventive group, treatment with hand serum, gloves/slippers and fortifying solution/dissolving oil will be started on the day of the first administration of Ac bispecific. In the curative group, treatment will begin on inclusion in the study and will be adapted to the lesions present on D0. Treatment will be readjusted on a weekly basis according to the lesions present at the time of the follow-up visit.
