Brief Summary:
This study is multicenter, double-blinded parallel group design, where participants with moderate to severe asthma with AFAD will be enrolled. Participants will receive three doses of 10 milligrams/kilogram (mg/kg) of GSK3772847 every 4 Weeks versus placebo along with standard of care. Participants will be randomized in 1:1 ratio to receive either 10 mg/kg GSK3772847 intravenously (IV) or matching placebo IV. Participants will receive study treatment on Week 0 (Day 1), Week 4 and Week 8. The total duration of the study will be 28 Weeks and approximately 46 participants will be randomized.

White blood cell (WBC) count with differential will include neutrophils, lymphocytes, monocytes, eosinophils and basophils.

  14. Number of participants with abnormal clinical chemistry parameters [ Time Frame: Up to Day 172 ]
    Laboratory assessment for clinical chemistry parameters will include blood urea nitrogen (BUN), potassium, calcium, sodium, creatinine, non-fasting glucose, Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline phosphate, Gamma-glutamyl transferase (GGT), albumin, phosphorus, carbon dioxide, total protein, creatine phosphokinase (CPK), total and direct bilirubin

  15. Number of participants with abnormal systolic blood pressure (SBP) and diastolic blood pressure (DBP) [ Time Frame: Up to Day 172 ]
    Blood pressure will be measured in supine position after 5 minutes rest

  16. Number of participants with abnormal heart rate [ Time Frame: Up to Day 172 ]
    Heart rate will be measured in supine position after 5 minutes rest

  17. Number of participants with abnormal findings in Electrocardiogram (ECG) [ Time Frame: Up to Day 88 ]
    Single 12-lead ECG will be obtained using an ECG machine that automatically measures heart rate, PR, QRS, QT, and QT interval corrected for heart rate (QTc) and ventricular rate
