Non-Tuberculous Mycobacterial (NTM) Infections

The goal of this clinical trial is to learn if a new combination antibiotic treatment (Arm D) works to treat a rare lung condition called mycobacterium abscessus pulmonary disease in people of any age and sex, when compared to the standard treatments. It will also learn about the safety of this new combination antibiotic treatment when compared to the standard treatments. The main questions it aims to answer are: * How well does Arm D treat mycobacterium abscessus pulmonary disease? * What side effects does Arm D cause when used to treat mycobacterium abscessus pulmonary disease? Researchers will compare Arm D to the current standard of care treatments to see if Arm D treats mycobacterium abscessus pulmonary disease better and if it will cause less side effects. Participants will: * Be screened and recruited to the FORMaT adaptive platform trial (NCT04310930) * Be given Arm D for 4 weeks or standard of care treatments for 6 weeks. * Be reviewed by the study doctors weekly for checkups and tests. * Provide respiratory samples (sample coughed up from the chest), respond to quality-of-life questionnaires, have CT lung scans and blood tests.

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.

The primary aim of the study is to investigate the correlation between patient-reported symptoms recorded in the diary and the microbiological and radiological disease course in patients with pulmonary infections caused by nontuberculous mycobacteria (NTM).
