Lamprene®/Clofazimine, is a product of the pharmaceutical company named Novartis Pharmaceuticals Corporation. Lamprene®/Clofazimine is approved by FDA (the U.S Food and Drug Administration) for the treatment of leprosy. It is no longer available through pharmacies in the US. It is being tested in non-Novartis clinical studies for drug resistant tuberculosis and non-tuberculous mycobacteria (NTM).

To be eligible for participation in this expanded access program, patients must have an NTM diagnosis. The treating physician has decided that this infection can be treated with Lamprene®/Clofazimine. This medicine is provided to the physician in an expanded access program. This means that this medicine is not registered for the treatment of NTM, but it can be used in special situations where there are no other possible treatments. For example, this may be because the patient has a type of Mycobacterial infection that is resistant or failed to respond optimally to other drugs, or because the patient has had side effects that prevent the use of other drugs. The physician must submit a patient registration form to initiate the patient approval process.

Inclusion Criteria:

1. Male or female patients 18 years of age or older
2. Written informed consent must be obtained before any project specific assessment is performed.
3. Patients previously diagnosed with NTM infection with local or disseminated infection(i.e. patients with any NTM species at any site of infection)
