Part B was removed due to the low numbers of participants enrolling into Part B. GSK determined it was no longer feasible to achieve a meaningful number of participants and therefore recruitment into this portion of the study was stopped.

| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants With a Reduced Need for Surgery at Week 25 | Week 25 | Assessment of the nasal polyposis condition was performed after six months of dosing to determine the situation indicative of a reduction in the need for surgery. The components used to determine the need for surgery were endoscopic polyp (ENP) scores and a severity of condition as measured by a visual analogue scale (VAS). Surgery was still deemed required for a participant with an ENP score of \>=3, or an ENP score of 2 and a VAS symptom score of \>7. The number of participants with reduced need for polyp surgery are presented as missing data set to non-responders (NR) and missing data last observation carry forward (LOCF). LOCF is defined as missing responses at Week 25 imputed with the last non-missing post-dose observation for that participant. |
| Secondary | Number of Participants With Endoscopic Nasal Polyp (ENP) Score Dynamics at Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Each nostril was assessed for polyps and graded at Weeks 1, 2, 5, 9, 13, 17, 21, and 25. The right and left nostrils were scored from 0 to 4, where, 0 = No polyps; 1 = Small polyps in the middle meatus not reaching below the inferior border of the middle concha; 2 = Polyps reaching below the lower border of the middle turbinate; 3 = Large polyps reaching the lower border of the inferior turbinate or polyps medial to the middle concha; and 4 = Large polyps causing complete obstruction/congestion of the inferior meatus. The ENP score was recorded for both the right and the left nostril. The higher of the two scores was derived and used for the analysis. The ENP score ranges from 0 to 4, with a higher score indicating a larger polyp. |
| Secondary | Number of Participants Who Required Polyp Surgery at Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Assessment of the nasal polyposis condition was performed after 6 months of dosing to determine the situation indicative of a reduction in the need for surgery. The components used to determine the need for surgery were endoscopic polyp scores and a severity of condition as measured by a VAS. Surgery was required for participants with ENP scores of \>=3, or ENP scores of 2 and a VAS symptom score of \>7. |
| Secondary | Mean Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at Weeks 2, 5, 9, 13, 17, 21, and 25 | Baseline and Weeks 2, 5, 9, 13, 17, 21, and 25 | SBP and DBP were measured at Baseline (Week 1) and at Weeks 2, 5, 9, 13, 17, 21, and 25. Baseline is defined as the Week 1 pre-dose assessment. Change from Baseline is defined as the difference between the post-dose post-Baseline visit value and the Baseline value. |
| Secondary | Mean Change From Baseline in Pulse Rate at Weeks 2, 5, 9, 13, 17, 21, and 25 | Baseline and Weeks 2, 5, 9, 13, 17, 21, and 25 | Pulse rate was measured at Baseline (Week 1) and at Weeks 2, 5, 9, 13, 17, 21, and 25. Baseline is defined as the Week 1 pre-dose assessment. Change from Baseline is defined as the difference between the post-dose post-Baseline visit value and the Baseline value. |
| Secondary | Number of Participants With the Indicated Electrocardiogram (ECG) Findings at Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | A single safety 12-lead ECG was performed using a standard 12-lead ECG machine at Weeks 1, 2, 5, 9, 13, 17, 21, and 25. Any abnormal clinically significant (CS) and not clinically significant (NCS) findings were identified. ECG abnormaility with respect to CS and NCS findings were judged by the investigator or appropriately qualified designee. Clinically significant abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition. |
| Secondary | Absolute Values of Clinical Chemistry Parameters Including Blood Urea Nitrogen (BUN), Glucose Fasting, Chloride, Sodium, Potassium, Carbon Dioxide, and Calcium at Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Week 1 pre-dose, Week 2, Week 5 pre-dose, Week 9 pre-dose, Week 13 pre-dose, Week 17 pre-dose, Week 21 pre-dose, and Week 25 (4 Weeks post last dose) | BUN, glucose fasting, chloride, sodium, potassium, carbon dioxide (CO2), and calcium were assessed at Week 1 pre-dose, Week 2, Week 5 pre-dose, Week 9 pre-dose, Week 13 pre-dose, Week 17 pre-dose, Week 21 pre-dose, and Week 25 (4 Weeks post last dose). |
| Secondary | Absolute Values of the Clinical Chemistry Parameters of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Gamma Glutamyltransferase (GGT) at Weeks 1, 2, 5, 9, 13, 17, 21, and 25 | Week 1 pre-dose, Week 2, Week 5 pre-dose, Week 9 pre-dose, Week 13 pre-dose, Week 17 pre-dose, Week 21 pre-dose, and Week 25 (4 Weeks post last dose) | ALT, AST, ALP, and GGT were assessed at Week 1 pre-dose, Week 2, Week 5 pre-dose, Week 9 pre-dose, Week 13 pre-dose, Week 17 pre-dose, Week 21 pre-dose, and Week 25 (4 Weeks post last dose). |
