ONSCREEN TEXT: NUCALA (mepolizumab) for Chronic Rhinosinusitis With Nasal Polyps
DR. FRANZESE: Hello, I am Dr. Christine Franzese from the Department of Otolaryngology - Head and Neck Surgery at the University of Missouri in Columbia. In this chapter, I will discuss the use of NUCALA (mepolizumab) for chronic rhinosinusitis with nasal polyps.
Before I begin, please listen as the narrator reviews the Indications and Important Safety Information for NUCALA.
ONSCREEN TEXT: INDICATIONS AND IMPORTANT SAFETY INFORMATION
SEA add-on maintenance treatment of adult and pediatric patients aged 6 years and older with severe asthma and with an eosinophilic phenotype. NUCALA is not indicated for the relief of acute bronchospasm or status asthmaticus.
CRSwNP add-on maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in adult patients 18 years of age and older with inadequate response to nasal corticosteroids.

NARRATOR: NUCALA is indicated for the:
add-on maintenance treatment of adult and pediatric patients aged 6 years and older with severe asthma and with an eosinophilic phenotype. NUCALA is not indicated for the relief of acute bronchospasm or status asthmaticus.
add-on maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in adult patients 18 years of age and older with inadequate response to nasal corticosteroids.
treatment of adult patients with eosinophilic granulomatosis with polyangiitis (EGPA).
treatment of adult and pediatric patients aged 12 years and older with hypereosinophilic syndrome (HES) for greater than or equal to 6 months without an identifiable nonhematologic secondary cause.
Contraindications: Known hypersensitivity to mepolizumab or excipients.
ONSCREEN TEXT: IMPORTANT SAFETY INFORMATION (cont’d) WARNINGS AND PRECAUTIONS. Hypersensitivity Reactions: Hypersensitivity reactions (for example, anaphylaxis, angioedema, bronchospasm, hypotension, urticaria, rash) have occurred with NUCALA. These reactions generally occur within hours of administration but can have a delayed onset (that is, days). Discontinue if a hypersensitivity reaction occurs.
Acute Asthma Symptoms or Deteriorating Disease: NUCALA should not be used to treat acute asthma symptoms, acute exacerbations, or acute bronchospasm.
Opportunistic Infections: Herpes Zoster: Herpes zoster infections have occurred in patients receiving NUCALA. Consider vaccination if medically appropriate.

ONSCREEN TEXT: IMPORTANT SAFETY INFORMATION (cont’d) WARNINGS AND PRECAUTIONS (cont’d) Reduction of Corticosteroid Dosage: Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of therapy with NUCALA. Decreases in corticosteroid doses, if appropriate, should be gradual and under the direct supervision of a physician. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy.
Parasitic (Helminth) Infection: Treat patients with pre-existing helminth infections before initiating therapy with NUCALA. If patients become infected while receiving NUCALA and do not respond to anti-helminth treatment, discontinue NUCALA until infection resolves.
Additional Important Safety Information for NUCALA will be presented later in this video.

DR. FRANZESE: In this chapter, I will discuss only the chronic rhinosinusitis with nasal polyposis indication.
ONSCREEN TEXT: Eosinophilic Inflammation Can Drive Nasal Polyp Recurrence1-3
[bar chart showing percent of postoperative nasal polyp recurrence during 30-month follow-up for patients with higher and lower-tissue eosinophil density.* The 22 patients with higher eosinophil density* had 82% recurrence. The 20 patients with lower eosinophil density had 25% recurrence.]
After surgery, nasal polyp recurrence was 3X greater in patients with elevated eosinophils1*
Up to 90% of recurrent nasal polyps have predominantly eosinophilic inflamation1,3-5†
*Based on a retrospective single-center study to investigate the relationship between eosinophil density in nasal polyp tissue and recurrence in adults who underwent endoscopic sinus surgery for massive nasal polyposis (filled at least half of each nostril). Patients were categorized as higher density (>4 eosinophils/1000 μm2) or lower density (≤3 eosinophils/1000 μm2) by examining digital images taken at x400 magnification.1 †Based on studies that examined the presence of eosinophil leukocyte infiltration in nasal polyp biopsy tissue of patients in the US and Europe.
DR. FRANZESE: Eosinophilic inflammation can drive nasal polyp recurrence. Up to 90% of recurrent nasal polyps in patients with CRSwNP have predominantly eosinophilic inflammation. In a retrospective study, nasal polyp recurrence was 3 times greater in patients with elevated eosinophils after surgery.
ONSCREEN TEXT: IL-5 Is Often Elevated in Nasal Polyp Tissue and Is Key for Eosinophil Survival6,7
IL-5 is the key cytokine responsible for the growth, recruitment, and survival of eosinophils6
[image of an IL-5s and Eosinophil to show correlation]
Increased IL-5 is correlated with recurrent nasal polyps2,8,9
DR. FRANZESE: IL-5 is often elevated in nasal polyp tissue and is key for eosinophil survival. IL-5 is the key cytokine responsible for the growth, recruitment, and survival of eosinophils. Also, increased IL-5 is correlated with recurrent nasal polyps.
ONSCREEN TEXT: NUCALA (mepolizumab) Inhibits Il-5, With Rapid Reduction in Blood Eosinophils10,11 NUCALA is a humanized IL-5 antagonist monoclonal antibody. [image of How NUCALA works] The MOA of mepolizumab has not been definitively established.
NUCALA binds to IL-5 and blocks its binding to the alpha chain of the IL-5 receptor complex on the eosinophil cell surface
This inhibits IL-5 signaling and reduces the production and survival of eosinophils
NUCALA reduced blood eosinophils by 74% within 48 hours.11‡
Results are descriptive. The clinical significance of these pharmacodynamics data is unknown.
‡ Data based on mepolizumab 75 mg IV (n=10) at first measurement post-dose from a phase 2 study in 70 adult patients with asthma and blood eosinophil counts ≥200 cells/μL (mean baseline blood is eosinophils: 348 cells/μL).10,11 Blood is eosinophil reduction data or based on geometric mean.
DR. FRANZESE: NUCALA is a humanized IL-5 antagonist monoclonal antibody that binds to IL-5 and blocks its binding to the alpha chain of the IL-5 receptor complex on the eosinophil cell surface. This inhibits IL-5 signaling and reduces the production and survival of eosinophils.
Please note the mechanism of action of mepolizumab has not been definitively established.
In a phase 2 study in asthma patients, NUCALA reduced blood eosinophils by 74% within 48 hours. These results are descriptive. The clinical significance of these pharmacodynamics data is unknown.

DR. FRANZESE: The efficacy and safety of NUCALA in CRSwNP was studied in SYNAPSE—a 52-week, multicenter, randomized, double-blind, placebo-controlled, phase 3 trial. It studied NUCALA 100 mg versus placebo subcue once every 4 weeks added to standard-of-care therapy in adult patients with recurrent CRSwNP.

Those in the CRSwNP trial were oropharyngeal pain and arthralgia. In the EGPA and HES trials with 300 mg of NUCALA, no additional adverse reactions were identified to those reported in severe asthma clinical trials.

A majority of systemic reactions were experienced the day of dosing.
ONSCREEN TEXT: IMPORTANT SAFETY INFORMATION (cont’d) USE IN SPECIFIC POPULATIONS The data on pregnancy exposures are insufficient to inform on drug-associated risk. Monoclonal antibodies, such as mepolizumab, are transported across the placenta in a linear fashion as the pregnancy progresses; therefore, potential effects on a fetus are likely to be greater during the second and third trimesters.
