If your COPD keeps flaring up even when you use your inhalers as directed, biologics are the add-on option to ask about. Two of them, Dupixent (dupilumab) and Nucala (mepolizumab), are approved for COPD in people with type 2 inflammation, and they are given by injection on top of your current treatment. A blood test helps show whether one of them fits you.
What is COPD, and which organ does it affect?
The organ is the lungs. COPD is a group of lung illnesses, including emphysema and often chronic bronchitis, that make it difficult to breathe. The Office on Women’s Health COPD page explains that the airways can become inflamed and scarred, that in emphysema the walls of the air sacs break down, and that COPD is a lifelong disease that usually gets worse over time.
Are biologics approved for COPD?
Yes, but for a specific group. The American Lung Association’s COPD page says there are two FDA-approved medications for the type 2 inflammation in COPD, and it names Dupixent and Nucala. A January 12, 2026 article on Consult QD, Cleveland Clinic’s clinician news site, says the same two biologics are approved for use in COPD, both for patients with type 2 inflammation. A 2019 review said no biologics were licensed for COPD at that time, which is why older articles sound different.
| Biologic | What it targets (per Consult QD) | How often it is given (per the American Lung Association) |
|---|---|---|
| Dupixent (dupilumab) | IL-4 and IL-13, key drivers of the type 2 inflammatory pathway | Every two weeks |
| Nucala (mepolizumab) | IL-5 | Every four weeks |
Who may qualify for a biologic?
Not everyone with COPD does. Your clinician orders a blood test that measures eosinophils, a type of white blood cell, to check for type 2 inflammation. The American Lung Association’s page says a biologic may be recommended if you have a certain level of blood eosinophils, moderate to severe COPD, and exacerbations despite optimal treatment.
Consult QD quotes a Cleveland Clinic pulmonologist describing the ideal candidate as someone who has already maximized standard inhaled therapies and still has two, three or more moderate-to-severe exacerbations per year. Biologics are not first-line treatment, the same article says.
The same pulmonologist said patients who keep smoking, do not take their inhalers, or have trouble affording their inhalers would not be good candidates. If that sounds like your situation, treat it as a reason to get support for quitting and for your inhalers, not as a closed door. The COPD stages guide explains what stage 2, 3 and 4 mean, and the spirometry test is how the Office on Women’s Health page says COPD is diagnosed.
What do the studies show?
The research is still developing. A 2023 review in the American Journal of Respiratory and Critical Care Medicine, the 2023 biologics outlook review, reports that 20 to 40 percent of patients with COPD exhibit type 2 inflammation, and it calls for biomarkers to help select the patients who would most benefit. A 2019 review in The Journal of Allergy and Clinical Immunology: In Practice, the 2019 T2 biologics review, found that anti-IL-5 biologics produced modest reductions in exacerbation frequency, that the benefit was related to baseline blood eosinophil count, and that the benefits were small compared with asthma.
Consult QD reports that dupilumab “has been shown to reduce exacerbations, increase lung function, and improve quality of life.” Mepolizumab’s initial tests did not show efficacy across all patients with COPD, but when the study group was narrowed to patients with type 2 inflammation, exacerbations were successfully reduced. The American Lung Association says that for people with type 2 inflammation, biologics can help reduce flare-ups, improve lung function and improve quality of life.
On asthma: Consult QD notes both drugs have also been used to treat asthma, and the 2019 review says biologics targeting type 2 immunity have been successful in severe asthma.
What are the side effects, and what will it cost?
The American Lung Association’s page says each medication has side effects, and that some of the more common ones are injection site reactions, allergic reactions, headache, back pain and diarrhea. Go over how these apply to your health history with your clinician.
Prices change and depend on your plan, so check your out-of-pocket cost with your insurer and pharmacy before you start.
Are biologics safer than prednisone?
That is a comparison to make with your clinician, because the answer depends on your exacerbation history, your blood test and your other health conditions. One point to raise: the Office on Women’s Health COPD page notes that more than half of people with COPD have osteoporosis, and that this may be related to steroid medicines sometimes used to treat COPD. It also notes that some studies show COPD is a risk factor for osteoporosis even without medicine.
What is the most successful treatment for COPD?
Quitting smoking is the only proven way to slow COPD, according to the Office on Women’s Health COPD page. The same page says medicines and other treatments can relieve some symptoms for some time, but they will not fix lung damage you already have.
Quitting is hard. The CDC smoking cessation facts report that less than 1 in 10 adults who smoke succeed in quitting each year, and that using counseling and medication together provides the best chance of quitting successfully. The CDC quit smoking medicines page says seven medicines are approved by the FDA to help you quit, including the nicotine patch, lozenge, gum, oral inhaler, nasal spray, varenicline and bupropion SR.
If you vape, know that the MyHealthfinder quit smoking page from the U.S. Department of Health and Human Services says the FDA has not approved e-cigarettes as a quit-smoking aid. The same page says it often takes people several tries to quit, that free help is available by calling 1-800-QUIT-NOW (1-800-784-8669), and that under the Affordable Care Act most insurance plans must cover treatment to help people quit smoking. Slipping back is a common part of the story, and each try teaches you something.
If quitting brings a cough or breathlessness you are not sure about, the withdrawal or COPD symptoms article explains how to tell them apart.
Can your lungs heal from COPD?
Not in the way the word heal suggests. The Office on Women’s Health COPD page says quitting smoking can improve COPD symptoms but cannot make COPD go away. What quitting does is slow further damage. The page says that one year after quitting, the rate of lung aging is almost back to normal, and that women showed twice as much improvement in breathing one year after quitting, in a study the page cites.
What else helps relieve COPD symptoms?
The Office on Women’s Health COPD page lists the steps a doctor may build a plan around: stopping smoking and avoiding secondhand smoke, medicines to open airways and lessen inflammation, pulmonary rehabilitation (exercise, training to manage the disease and counseling), oxygen therapy for severe COPD, and flu and pneumonia shots. It also advises limiting exposure to smoke, dust, fumes and chemicals at home and work. Lung transplant is a last resort for very severe cases, the page says.
Talk to your doctor if you have a cough that won’t go away, trouble breathing, or pain or discomfort in your chest. If breathing suddenly becomes much harder, call 911 or your local emergency number rather than waiting for an appointment. If you are unsure whether your symptoms should be checked, COPD early signs covers when to get screened.
What is still investigational?
Tezepelumab is an asthma drug that blocks TSLP. Consult QD describes it as an emerging COPD treatment in the pipeline and potentially another agent for COPD. The same article notes that Cleveland Clinic is taking part in an ongoing multicenter study of airway scaffolding, a technique aimed at decreasing trapped air in severe emphysema. Only Dupixent and Nucala are described as approved for COPD.
Questions to bring to your appointment
- Do my symptoms and history suggest type 2 inflammation, and when will my blood eosinophil test be done?
- How many moderate-to-severe flare-ups have I had while using my inhalers as directed?
- How does my smoking or vaping status affect whether a biologic is right for me?
- How would a biologic compare with a steroid medicine in my case?
- What would I pay, and what does my insurance cover?
- Does my care plan follow current GOLD guidelines?
