Mycobacterium Infections, Nontuberculous
About this trial
This is an interventional treatment trial for Mycobacterium Infections, Nontuberculous
Eligibility Criteria
Inclusion Criteria:
- History of chronic pulmonary infection with MAC or M. abscessus (defined as at least 2 documented positive sputum cultures in the prior 2 years, of which at least one was obtained in the 6 months prior to Screening).
Subject fulfills one of the following criteria:
- Subjects who remain sputum culture positive while currently on a multidrug NTM guideline based antimycobacterial regimen, which has been ongoing for at least 6 months prior to the Baseline Visit
- Subjects who remain sputum culture positive but have either stopped a multidrug NTM guideline based antimycobacterial regimen at least 28 days prior to Screening due to lack of response or intolerance, or never started such treatment.
- Ability to produce at least 2 mL of sputum or be willing to undergo an induction that produces at least 2 mL of sputum for clinical evaluation.
- Female or male ≥18 years of age.
- Females who have been post-menopausal for more than 1 year or females of childbearing potential after a confirmed menstrual period using a highly efficient method of contraception (i.e. a method with less than 1% failure rate such as combined hormonal contraception, progesterone-only hormonal contraception, intrauterine device, intrauterine hormone- releasing system, bilateral tubal occlusion, vasectomized partner, sexual abstinence), during and until thirty (30) days after last dose of trial treatment. Females of childbearing potential must have a negative serum pregnancy test at Screening (Visit 1) and a negative urine pregnancy test at dosing at Baseline (Visit 2) and must not be lactating.
- Males agreeing to use condoms during and until thirty (30) days after last dose of medication, or males having a female partner who is using adequate contraception as described above.
- Willing and able to provide signed informed consent.
- Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures specified in the protocol as judged by the investigator
Exclusion Criteria:
- Subjects diagnosed with cystic fibrosis.
- Prior therapy with inhaled or systemic GM-CSF.
- Subjects with hemoptysis of ≥60 mL in a 24 hour period within 4 weeks prior to Screening.
- Concurrent disease with a life expectancy of less than 6 months.
- History of, or present, myeloproliferative disease, leukemia or other hematological malignancy.
- Active pulmonary malignancy (primary or metastatic); or any malignancy requiring chemotherapy or radiation therapy within one year prior to Screening or anticipated during the study period.
- Active allergic bronchopulmonary mycosis or connective tissue disease, inflammatory bowel disease or other autoimmune disorder requiring therapy associated with significant immunosuppression, such as systemic corticosteroids at a dose equivalent of 10 mg/day or more of prednisolone, within 3 months prior to Screening or anticipated during the study period.
- Pulmonary tuberculosis requiring treatment or treated within 2 years prior to Screening.
- HIV infection or other disease associated with significant immunodeficiency.
- History of lung transplantation.
- Any change in chronic NTM multi-drug antimycobacterial regimen within 28 days prior to Screening.
- Treatment with any investigational medicinal product within 3 months of Screening.
- Previous experience of severe and unexplained side-effects during aerosol delivery of any kind of medicinal product
Any other serious medical condition which in the opinion of the investigator would make the subject unsuitable for the trial.

Inhaled molgramostim/antimycobacterials
Inhaled molgramostim
Inhaled molgramostim administered in subjects who remain sputum culture positive while currently on a multidrug Nontuberculous Mycobacterial (NTM) guideline based antimycobacterial regimen, which has been ongoing for at least 6 months prior to the Baseline Visit
Inhaled molgramostim administered in subjects who remain sputum culture positive but have stopped a multidrug Nontuberculous Mycobacterial (NTM) guideline based antimycobacterial regimen at least 28 days prior to Screening due to lack of response or intolerance, or who never started such treatment
