MAC Clinical Trial | MAC Lung Disease

Consider joining MACrO 2, a MAC clinical research study (MAC clinical trial).MACrO 2 is for people with Mycobacterium avium complex (MAC) lung disease that has not responded to prescribed antibiotic medications.. MAC is a type of nontuberculous mycobacteria (NTM) lung disease. Study Overview Learn more

ARISE/ENCORE Clinical Trial Program for MAC Lung Disease

Insmed is conducting a clinical study for MAC lung disease patients. The results of this study will help researchers gain a better understanding of a study treatment being evaluating for potential treatment of MAC lung infections and for improved symptoms including decreased respiratory discomfort and fatigue. You may receive study-related treatment at no cost and reimbursements for your site visits. If you qualify to enroll and decide to participate, you will be assigned to one of two studies for individuals with MAC lung disease. Please visit to learn more about the study and to see if you may qualify.

Further Details and Next Steps:

• First, see if you may qualify using the website linked above. A patient outreach representative will call you and help guide you through the process.

• Then, a research site will assess if you meet the criteria to participate in the study. If you qualify you will be assigned to one of two studies.

• Throughout the study, you will take daily study drugs and have visits with your clinical team.

MAC2v3 Pragmatic Clinical Trial

We are a team of researchers at Oregon Health and Science University and 20+ partner sites across the United States and Canada conducting a Patient-Centered Research Outcomes Institute (PCORI)-funded pragmatic trial to determine whether 2-drug therapy is as effective as and more tolerable than 3-drug therapy for pulmonary MAC disease, or “MAC2v3”. Information Page with eligibility criteria:

Let us support you with guidance from NTM experts as your uncomplicated pulmonary MAC patients begin treatment! MAC2v3 study participation has been expanded to include virtual enrollment and telehealth visits. The study team is now able to enroll patients from any health care provider nationwide. However, we need to enroll them prior to starting treatment. Once randomized, patients are monitored per usual care in collaboration with your clinic. Data collection is managed by the enrolling site. Please contact if you are interested in participating and providing this opportunity to your patients.

Home Sputum Collection Project

The COPD Foundation and NTM Info & Research, in partnership with a team of experts at National Jewish Health has designed a pilot program aimed at improving the current process for sputum testing. There will be no cost to the patient or physician as part of this pilot program.
  • Patients are able to provide sputum samples in the home setting

  • We can improve timelines of results and provide access to increased species identification and drug susceptibility testing

  • Home sputum collection provides a safe and accessible alternative to producing sputum in the laboratory setting

To learn more about the Home Sputum Collection Project and eligibility criteria, visit Physicians interested in participating must complete an initial screening survey here.
