Summary

Prospective, interventional, open, randomized, single-center, non-commercial clinical trial to optimize treatment and dosage of vemurafenib in juvenile patients with histiocytosis resistant to conventional therapy and in whom the BRAF gene mutation has been found.

Detailed description

BRAVO clinical study is part of the POLHISTIO project. The POLHISTIO project is a non-commercial clinical trial aimed at optimizing the diagnosis and treatment of juvenile patients with histiocytosis. The project objectives are defined as follows: 1) to estimate the nature and frequency of mutations in patients with histiocytosis in both tumor tissues and free-circulating DNA; 2) to compare molecular test results with clinical data; 3) to evaluate the diagnostic usefulness of the status of molecular analysis (MRD) as a prognostic factor compared with other recognized factors; 4) in the case of failure of conventional therapy - to modify treatment and to apply targeted treatment, based on molecular status of gene mutation. The project is intended to include patients from all over Poland.
