Therapeutic Drug Monitoring of BRAF-mutated Advanced Melanoma

Not Applicable
Completed
Conditions
Melanoma (Skin)
Interventions
Other: Blood sampling
Registration Number
NCT03416933
Lead Sponsor
Institut de Cancérologie de Lorraine
Brief Summary

BRAF V600-mutant metastatic melanoma are commonly treated using a combination of anti-BRAF and anti-MEK tyrosine kinase inhibitors (TKIs). The OPTIMEL trial aims to study the interest of therapeutic drug monitoring (TDM) of TKIs and circulating tumor DNA (ctDNA) detected in plasma of patients with metastatic melanoma for disease monitoring. 35 patients with metastatic melanoma and treated with dabrafenib and trametinib will be enrolled in this trial. Blood samples will be collected for the determination of TKIs concentration and ctDNA detection.

Link between the presence of circulating tumor DNA and plasma concentrations of kinase inhibitors n patient with advanced BRAF(V600) mutated melanoma1 day

ctDNA in patient with advanced BRAF(V600) mutated melanoma is estimated by the ratio of the Ct of the sample to the control. Plasma concentrations of anti-BRAF and anti-MEK tyrosine kinase inhibitors are expressed in μg / mL
