Pharmacokinetic Study With a Loading Dose of Clofazimine in Adult Patients With Nontuberculous Mycobacterial Disease

"All participants will receive an (experimental) oral loading dose regimen of 300 mg clofazimine once daily (= 3 capsules of 100 mg) for 4 weeks. Afterwards, all participants will continue with a standard oral dose of 100 mg clofazimine once daily (= 1 capsule of 100 mg) until a total 4 months of treatment with CFZ.~Blood samples will be taken at Day 28 (+/- 2 days), Day 29 (Day 28 +1) and after 4 months of treatment to assess the pharmacokinetics of CFZ, both with the loading dose and the standard dose. In addition, the safety/tolerability of CFZ will monitored."
