A Prospective, Multicenter, Single-arm MAC-PD Cohort: a NTM-NET and ESGMYC Collaborative Study (MAC-PD cohort)
November 16, 2023 updated by: Radboud University Medical Center
To gain insight in the effectiveness of, adherence and adjustments to guideline-based three-drug antimycobacterial therapy in patients with Mycobacterium avium complex pulmonary disease (MAC-PD) during the first 6 months of treatment.

Detailed Description
Mycobacterium avium complex (MAC) is the most frequent causative species that results in nontuberculous mycobacterial pulmonary disease (NTM-PD).
Current treatment outcomes for MAC-PD are unsatisfactory with sputum culture conversion rates between 50-70%.The high prevalence of drug toxicity and low adherence to guideline-based treatment (GBT) are key reasons for the limited treatment success.
Hence, there is an unmet need for prospective data on effectiveness of, adherence and adjustments to MAC-PD treatment regimens.
By collaborating with NTM-NET and ESGMYC affiliated medical centers, we enable systematic, prospective data collection of an international MAC-PD cohort.

Study Population
Patients with Mycobacterium avium complex pulmonary disease that (MAC-PD) requires guideline-based three-drug antimycobacterial therapy.
MAC is the most common causative species of pulmonary NTM infections.
Description
Inclusion Criteria:
- Newly diagnosed MAC-PD (primary or recurrent) as per the international NTM guideline that requires three-drug antimycobacterial treatment
- Signed and dated informed consent
Exclusion Criteria:
- The participant is in poor general condition where participation in the study cannot be accepted per discretion of the Investigator
- The participant has a known or suspected, current drug or alcohol abuse, that is, in the opinion of the Investigator, sufficient to compromise the safety or cooperation of the patient
- HIV-infection;
- Cystic fibrosis;
- >1 month antibiotic treatment for current MAC infection;
- < 6 months between previous antimycobacterial NTM-PD treatment and antimycobacterial treatment for current MAC-PD
- Disseminated MAC infection;
- Active pulmonary tuberculosis, fungal or nocardial disease requiring treatment;
- Active pulmonary malignancy (primary or metastatic) or any other malignancy requiring chemotherapy or radiotherapy within 6 months before screening or anticipated during the study period;
