I would then seek another Pulmonology Physician. It took me 3 solid months of research on the valves to learn all I could. I finally decided that Duke University could afford me the best experience and received a referral to their Interventional Pulmonary Department. I called the Staff and they were terrific. The Valves have been approved since 2018, however, Duke's Pulmonary team had been on the ground level of research and has been working with them for over 16 years. Dupixent is a little different story.... the FDA has not formally approved it for COPD, but has for Eosinophilic asthma, but it is on the fast tract and should be approved by June of this year. BUT, physicians can and often do write prescriptions for medication for what is called "off-label" medication. In fact about 20% of prescriptions written are for off-label use. There is criteria you should meet prior to being placed on Dupixent for COPD. Hope this gives you a little background info to move forward if you feel the need. Even if it means finding a new Practitioner.
