Application Number:	14/838,503
Patent Claims:	1. A method of treating moderate to severe eosinophilic asthma in a patient comprising: administering a therapeutically effective dose of reslizumab to the patient, wherein prior to the administering, the patient's symptoms are inadequately controlled with a current asthma therapeutic and the patient's blood eosinophil levels are equal to or greater than 400/.mu.l; and following the administering, the patient exhibits a significantly improved FEV.sub.1 treatment effect and wherein the patient's use of systemic corticosteroids is reduced by about 50% as compared to a patient not receiving reslizumab. 2. The method of claim 1, wherein the patient's blood eosinophil levels are equal to or greater than 500/.mu.l, 600/.mu.l, 700/.mu.l, or 800/.mu.l. 3. The method of claim 1, wherein the therapeutically effective dose of reslizumab is about 0.3 mg/kg to about 3 mg/kg. 4. The method of claim 1, wherein the therapeutically effective dose of reslizumab is administered intravenously or subcutaneously. 5. The method of claim 1, wherein the therapeutically effective dose of reslizumab is administered once about every 4 weeks. 6. The method of claim 1, wherein the current asthma therapeutic comprises an inhaled corticosteroid. 7. The method of claim 6, wherein the current asthma therapeutic comprises a medium dose inhaled corticosteroid. 8. The method of claim 7, wherein the inhaled corticosteroid is at least equivalent to about 440 .mu.g fluticasone. 9. The method of claim 6, wherein the inhaled corticosteroid comprises a high dose of inhaled corticosteroid. 10. The method of claim 6, wherein the current asthma therapeutic further comprises a long acting beta 2 adrenoceptor agonist. 11. The method of claim 1, wherein administration of the therapeutically effective dose of reslizumab also leads to an improvement in lung function, as assessed by forced vital capacity, forced expiratory flow rate, or any combination thereof. 12. The method of claim 11, wherein the improvement in lung function is equal to or greater than about 5% as compared to a patient not receiving reslizumab. 13. The method of claim 1, wherein administration of the therapeutically effective dose of reslizumab leads to a reduction of clinical asthma exacerbations, reduction of use of systemic corticosteroids, improved asthma control questionnaire score, improved asthma quality of life questionnaire score, or any combination thereof. 14. The method of claim 13, wherein the clinical asthma exacerbations are reduced by about 50% as compared to a patient not receiving reslizumab.
