Cystic fibrosis affects over 7,500 people in the UK [2]. These drugs, which are called CFTR protein modulators, are able to restore CFTR function to a level of about 4050% of normal [, However, opportunistic infections remain the main issue for CF individuals, with those from NTM increasing alarmingly [, The therapy for pulmonary MABSC infections remains extremely difficult, being resistant to aminoglycosides, rifamycins, tetracyclines, and -lactams [, Therefore, it is necessary to continue to find alternatives to curb this problem.
