Detection of Plasmatic Cell-free BRAF and NRAS Mutations : a New Tool for Monitoring Patients With Metastatic Malignant Melanoma Treated With Targeted Therapies or Immunotherapy ( MALT )
Protocol ID
NCT03493230
Lead Sponsor
Centre Hospitalier Universitaire de Nice
Brief Summary
The main objective of this project is to perform a longitudinal monitoring of BRAF and NRAS cell-free DNA in a large cohort of metastatic melanomas patients before treatment and during the follow-up. Results will be compared with clinical data as imaging (based on RECIST criteria) and the activity of lactate dehydrogenase in serum (LDH).
Detailed Description
During a consultation of follow-up for an advanced malignant melanoma (stage IIIb or IIIC or IV), an investigator presents the study to the patient and give him the note of information and the informed consent. The patient can benefit from a reflexion period of of 7 days. In case of agreement, a first blood draw will take place before initiation of any treatment. Between D15 and D30 a second blood draw will be taken. Then a blood draw will be necessary every two months until recurrence or progression of the disease for a maximum of 22 months.
