Biologic therapies represent a major shift in how doctors treat severe asthma and chronic obstructive pulmonary disease (COPD), offering hope to patients who haven't responded to traditional treatments. These medications work by targeting your immune system to reduce inflammation in your airways, potentially transforming the lives of people with hard-to-control respiratory conditions. However, access to these treatments isn't universal, and understanding who qualifies and how they work is essential for patients considering this option .

What Are Biologics and How Do They Work?

Biologics are a specialized class of medications that function differently from standard asthma and COPD treatments. Rather than simply opening airways or providing quick relief, biologics address the root cause of inflammation by targeting specific immune system pathways. They contain monoclonal antibodies, which are laboratory-made proteins that mimic the antibodies naturally produced by your body .

The key to understanding biologics lies in recognizing what causes severe asthma and COPD flare-ups. In many cases, inflammation in the lungs is triggered by eosinophils, a type of white blood cell that normally helps your immune system function properly. However, when you have severe asthma or COPD, you may have too many eosinophils in your blood, causing excessive inflammation in your airways. Biologics work by blocking the changes that lead to this harmful inflammation, whether it's caused by allergies or elevated eosinophil levels .

Who Actually Qualifies for Biologic Treatment?

Not everyone with asthma or COPD will benefit from biologics, and doctors use strict criteria to determine eligibility. Your lung specialist will evaluate whether you meet specific requirements before recommending this treatment. The process involves careful assessment to ensure you're a good candidate and that biologics are the right next step for your condition .

For asthma patients, you typically qualify if you meet these conditions:

• Frequent attacks: You're experiencing a lot of asthma attacks despite other treatments.
• High steroid use: You're taking a lot of oral steroids to manage your asthma symptoms.
• Treatment resistance: Other asthma medications aren't helping you control your condition effectively.
• Specialist recommendation: A lung specialist believes biologics could help your specific type of asthma.

For COPD patients, the eligibility criteria are similarly specific. You generally qualify if you have uncontrolled COPD, meaning you've had two or more flare-ups treated with steroids or antibiotics in the past year, or at least one flare-up requiring hospitalization. Additionally, you must have high amounts of eosinophils in your blood and be using specific inhaler combinations as prescribed .

What Tests Will Your Doctor Run?

Before starting biologic therapy, your specialist will conduct several diagnostic tests to confirm you're a suitable candidate. These assessments help determine whether your inflammation is the type that biologics can effectively target. Your doctor may perform a blood test to measure your eosinophil count, as this number is crucial in determining which biologic might work best for you .

Your specialist might also conduct a FeNo test, which measures fractional exhaled nitric oxide to assess how inflamed your airways are. Beyond these respiratory-specific tests, your doctor will verify that you're managing any other health conditions you have and confirm that you're using your existing asthma or COPD medicines correctly, including checking your inhaler technique .

Six Biologic Options for Severe Asthma

If you qualify for biologic therapy for asthma, your specialist will help you choose from six available medications, each with slightly different mechanisms of action. The specific biologic recommended for you depends on your individual inflammation profile and how your body responds to treatment .

• Mepolizumab (Nucala): Administered as an injection every four weeks to reduce eosinophil-driven inflammation.
• Reslizumab (Cinqaero): Given through a drip every four weeks for patients with eosinophil-related asthma.
• Benralizumab (Fasenra): Injected every four weeks for the first three treatments, then every eight weeks for ongoing management.
• Omalizumab (Xolair and Omlyclo): Administered as an injection every two to four weeks, depending on your specific needs.
• Dupilumab (Dupixent): Injected every two weeks for patients with certain types of severe asthma.
• Tezepelumab (Tezspire): Given as an injection every four weeks for broader asthma control.

One Biologic Option for COPD

COPD patients have fewer biologic options compared to asthma patients, but dupilumab (brand name Dupixent) has shown promise for those with uncontrolled disease and elevated eosinophil levels. This medication works similarly to its use in asthma, targeting the inflammatory pathways that drive COPD flare-ups .

How to Prepare for Biologic Therapy

Starting biologic therapy requires careful planning and coordination with your specialist team. You'll need to visit a severe asthma or COPD specialist center to begin treatment, which may not be in your local area. It's important to consider travel time and costs before your first appointment, as the NHS offers advice about getting help with travel expenses .

Once you begin biologics, remember that these medications are add-on treatments, meaning you continue taking your regular asthma or COPD medicines alongside them. Never reduce or stop your usual medications without discussing it with your specialist team, as this could compromise your respiratory health .

Tips for Managing Biologic Treatment at Home

• Learn proper injection technique: If it's safe and appropriate for you, your specialist will teach you or your caregiver how to inject biologics at home using prefilled syringes or pens.
• Store medications correctly: Biologics come in prefilled syringes or pens that must be stored in your refrigerator to maintain their effectiveness.
• Attend regular reviews: Your specialists will review your treatment regularly after you start biologics to ensure it's working effectively for your condition.
• Plan for initial clinic visits: Usually, a nurse will come to your house and administer your first two injections before you transition to self-injection at home.
• Schedule follow-up appointments: If you've been using steroid tablets long-term, you should see your specialists every four to eight weeks; otherwise, every three to six months is typical.

What Happens If You Don't Qualify for Biologics?

If biologic therapy isn't right for you, your specialist has other options to discuss. For asthma patients who don't qualify, treatments like bronchial thermoplasty or other specialist interventions may be considered. For COPD patients, alternatives might include antibiotics for recurrent infections or lung volume reduction surgery in specific cases .

Why COPD Remains Underdiagnosed in Hispanic Communities

While biologic therapies represent a major advancement, access to these treatments depends first on getting an accurate diagnosis, which remains a significant challenge for many Hispanic and Latino communities. Even though reported COPD rates are lower in Hispanic populations compared to non-Hispanic White adults, approximately 2% versus 5-6% respectively, this disparity may reflect underdiagnosis rather than true lower disease prevalence .

Many Hispanic patients with COPD symptoms don't receive early diagnosis because their symptoms are mistakenly attributed to aging, asthma, or infections. Spirometry, a simple breathing test that confirms COPD diagnosis, may not be used as consistently as it should be in evaluating Hispanic patients with respiratory symptoms. When COPD goes undiagnosed, patients miss out on treatments that could improve breathing, reduce symptoms, and slow disease progression .

Barriers to COPD Care in Hispanic Communities

Hispanic families face real-world obstacles that affect their ability to access respiratory care and biologic treatments. Limited access to specialists, lack of Spanish-speaking providers, difficulty getting to appointments, and health advice that may not reflect cultural needs all contribute to delayed diagnosis and treatment. Good communication is essential in COPD care, and when patients don't fully understand how to use their inhalers or can't clearly describe their symptoms, their condition may worsen .

These barriers can lead to serious consequences. Smoking may continue without proper support to quit, inhalers may be used incorrectly, important vaccines may be missed, pulmonary rehabilitation may not be offered, and hospital visits and long-term healthcare costs may increase. Some studies suggest that COPD may be significantly underdiagnosed in Hispanic smokers, especially when spirometry isn't routinely used .

Steps to Advocate for Your COPD Care

• Learn about COPD: Understand what COPD is and how it affects breathing so you can recognize symptoms early and communicate effectively with your doctor.
• Request spirometry testing: If you have symptoms like cough, wheezing, or shortness of breath, specifically ask your doctor about spirometry to confirm or rule out COPD diagnosis.
• Find culturally competent care: Look for doctors who speak Spanish or ask for interpreter services to ensure clear communication about your symptoms and treatment options.
• Master your inhaler technique: Ask your healthcare provider to demonstrate proper inhaler use and confirm you're using it correctly at each visit.
• Access support resources: Join support groups, local or online, to learn from others with COPD and get practical advice for managing your condition.
• Pursue smoking cessation: Ask about smoking cessation programs offered in Spanish, as quitting is one of the most important steps in managing COPD.
• Stay current on vaccines: Make sure you're up to date on flu, pneumonia, and COVID-19 vaccinations, which are critical for COPD patients.

The combination of advanced biologic therapies and improved access to diagnosis represents a significant opportunity for COPD and severe asthma patients. However, ensuring that all communities, including Hispanic and Latino populations, have equal access to these life-changing treatments requires addressing systemic barriers to care and improving early diagnosis through consistent use of spirometry and culturally competent healthcare .
