About Us

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 MAC pulmonary disease, or “MAC2v3”.

Do you have patients who are newly diagnosed with MAC pulmonary disease?

Let us support you with guidance from NTM experts as your MAC patients begin treatment! MAC2v3 study participation has been expanded to include virtual enrollment and telehealth visits. The study team is 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. There is no extra paperwork for you, data collection is managed by the enrolling site. Please contact MAC2v3@ohsu.edu if you are interested in participating and providing this opportunity to your patients.
