SHARING A BREATH Interdisciplinary Management of Patients With Severe Asthma

Educational Objectives Upon completion of this activity, participants will be better able to:  Identify patients with asthma who may be appropriate candidates for specialist follow‐up based on ongoing symptoms, exacerbation history, and treatment responses  Discuss biologic options that have been approved by the US Food and Drug Administration for the treatment of severe asthma  Coordinate the management of patients with severe asthma who require multidisciplinary care to maximize symptom control, reduce exacerbation risks, and minimize medication‐related toxicities  Educate patients with severe asthma about disease‐related risks, long‐term treatment options, and information related to adherence and self‐management

Uncontrolled vs Severe Asthma  “Asthma may be considered uncontrolled either because of persistence of symptoms despite appropriate treatment, or due to poor adherence to therapy or use of inhaler devices.”1  “Severe asthma is asthma that is uncontrolled despite adherence with maximal optimized therapy and treatment of contributory factors, or that worsens when high‐ dose treatment is decreased.”2

Best Practices in Patient Evaluation a. Carefully consider other possible disorders in the differential diagnosis, and confirm asthma diagnosis with physiologic testing

Confirm asthma diagnosisa Assess disease severityb Evaluate triggers that affect asthma

b. Standardized questionnaires (including rescue inhaler use), exacerbation history, measurement of biomarkers

Evaluate comorbid states that affect asthma

c. Less than 50% of medication prescribed for asthma is taken by patients; poor inhaler technique in up to 75% of patients

Assess treatment adherence and inhaler techniquec

Under‐ and Overdiagnosis of Asthma Underdiagnosis of current asthma

Overdiagnosis of current asthma

No diagnosis made, or a disease or condition other A disease or condition other than asthma that than asthma that causes respiratory symptoms has causes respiratory symptoms (such as allergic been assigned to the patient rhinitis, GERD, or vocal cord dysfunction) OR Patient’s previous asthma is in sustained clinical remission (in the absence of controller treatment, or after controller treatment has been stopped)  People who have asthma that is undiagnosed suffer from poorer health‐related quality of life and more absenteeism from work and school  People with overdiagnosed asthma suffer from potential side effects related to unnecessary use of medications, the burden of increased drug costs, and a delay in identifying and addressing the true cause of their respiratory symptoms

Unmet Needs in Patients With Asthma  Careful assessment of current adherence to asthma guideline recommendations is an important first step when considering an asthma biologic  28% of patients who had uncontrolled asthma failed to improve after 1 year of guideline‐ recommended care1

 Even after ensuring guideline/medication adherence, considering safety of these agents, and using available biomarkers to estimate treatment response, patient access to the biologic is needed2

Prescribers of biologics for asthma should consider how best to assess and improve medication adherence to ICS/LABA before considering the use of a biologic agent.2 20

Kira, 4 Months Later  New regimen includes a combination ICS/LABA  Recent episode of “bronchitis” sent Kira her to an urgent care clinic while she was out of town, where she was prescribed a course of prednisone and an antibiotic  Continues to use her rescue inhaler 4 or 5 times weekly  Has canceled activities and plans arising from daytime and nighttime asthma symptoms  Kira and her physician confirm together that she is using her medications properly, and confirm that any asthma triggers are under control

Other Controller Options Other Reliever Option

As‐needed low‐dose ICS‐ formoterol

STEP 2

STEP 3

Daily low‐dose ICS or as‐ needed low‐ dose ICS‐ formoterol

Low‐dose ICS +LABA

Low‐dose ICS LTRA, or low ‐ Medium‐dose taken dose ICS taken ICS, or low‐dose whenever whenever ICS+LTRA SABA taken SABA is taken

STEP 4

STEP 5

Medium/high‐dose ICS+LABA

High‐dose ICS+LABA Refer for phenotypic assessment ± add‐on therapy, eg, tiotropium, anti‐IgE, anti‐IL5/5R, anti‐IL4R

High‐dose ICS, add‐ on tiopropium, or add‐on LTRA

Add low‐dose OCS, but consider side effects

As-needed low-dose ICS-formoterol As-needed short-acting β2 -agonist (SABA) Each step requires Patient education and efforts to address modifiable risk factors and comorbidities.

Black Box Warning


What Patients Need to Know About Biologic Therapies for Severe Asthma Biologic agents —  Are used to treat uncontrolled moderate or severe asthma  Do not cure asthma  Are added to a patient’s current treatment regimen  Must be taken regularly, like all asthma medicines  Are injectable medications  Some biologics can be self‐administered at home, whereas others must be administered in a doctor’s office

Overcoming Challenges With Treatment Adherence  Assess for adherence

 Reasons for nonadherence

 Inspect medication dose counters

 Inadequate access to medication  Dissatisfaction with medication delivery  Perceived adverse effects  Lack of improvement with medication noted by patient

• Breath‐actuated devices are more accurate

 Check pharmacy refill records

Seek to understand and address reasons for low adherence, particularly defining the purpose of the medication and why it is essential to patient care. 39

Conclusions  Identifying patients with poorly controlled, severe asthma is critical  Targeted biologic therapies can improve symptoms, decrease exacerbation risks, and improve QoL in certain patients who have severe asthma  An anti‐IgE biologic is FDA approved for patients with moderate‐to‐severe, persistent allergic asthma, a positive skin test or in vitro reactivity to a perennial aeroallergen, and age/body weight serum IgE levels  Three biologic therapies targeting IL‐5 signaling are now FDA approved for patients with severe eosinophilic asthma  A biologic agent targeting IL‐4Rα is now FDA approved for patients with moderate‐to‐ severe asthma aged ≥12 years who have an eosinophilic phenotype or OCS–dependent asthma  A biologic agent targeting TSLP is in late‐stage clinical development
