Primary Outcome Measures :
  1. Change From Baseline in Nasal Polyp Score (NPS) to Week 16. [ Time Frame: Week 16 ]
    Total scoring 0-8, scoring of 0-4 [0 - no polyps, 4 - large polyps causing complete obstruction] bilateral

  2. Change From Baseline in Sino-Nasal Outcome Test -22 (SNOT-22) Score from Week 16. [ Time Frame: Week 16 ]
    Total scoring 0-110, scoring of 0-5 [0 - no problem, 5 - problem as bad as it can be] (22 items)

Secondary Outcome Measures :
  1. Time to first response in nasal polyp score. [ Time Frame: Week 16 ]
  2. Responder analysis: response defined as a reduction of at least 1 point from Baseline to Week 16 in nasal polyp score [ Time Frame: Week 16 ]
  3. Responder analysis: response defined as a reduction of at least 12 points from Baseline to Week 16 in SNOT-22. [ Time Frame: Week 16 ]
  4. Change from Baseline to Week 16 in sense of smell as assessed by the University of Pennsylvania Smell Identification Test (UPSIT). [ Time Frame: Week 16 ]
  5. Incidence of adverse events and treatment emergent adverse events. [ Time Frame: Week 24 ]
  6. Incidence of serious adverse events. [ Time Frame: Week 24 ]
  7. Changes in clinical laboratory tests (hematology, chemistry and urinalysis). [ Time Frame: Week 24 ]
  8. Changes in vital signs (BP, temperature, respiration rate, and pulse rate). [ Time Frame: Week 24 ]
  9. Changes in ECG parameters. [ Time Frame: Week 24 ]
  10. Immunogenicity (ADA and neutralizing ADA) [ Time Frame: Week 24 ]
  11. CL/F, apparent volume of distribution, Cmax, tmax. [ Time Frame: Week 24 ]
