E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of tezepelumab on Nasal Polyp Score and Participant Reported Nasal Congestion |
|
E.2.2 | Secondary objectives of the trial |
Key Secondary Objectives:
To evaluate the effect of tezepelumab on, loss of smell, nasal polyp-quality of life compared with placebo, NP surgery and/or receiving SCS for NP, sinus opacification, NPSD total symptom score (TSS), and lung function in participants with co-morbid asthma and aspirin exacerbated respiratory disease (AERD) /nonsteroidal anti-inflammatory drug exacerbated respiratory disease (NSAID-ERD).
Other Secondary Objectives:
To evaluate the effect of tezepelumab on NPS, participant reported NC, loss of smell, sinus opacification, systemic corticosteroid use, NPSD, NPIF, asthma control in participants with co-morbid asthma and AERD/NSAID-ERD, and to evaluate the PK and immunogenicity of tezepelumab. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Participants with physician-diagnosed CRSwNP for at least 12 months prior to Visit 1 that have: a. Severity consistent with need for surgery as defined by total NPS ≥ 5 (≥ 2 for each nostril) at screening, as determined by the central reader b. Nasal Congestion Score (NCS) ≥ 2 at Visit 1 c. Ongoing documented NP symptoms over > 8 weeks prior to screening such as rhinorrhea and/or reduction/loss of smell 2. SNOT-22 total score ≥ 30 at screening (Visit 1) 3. Any standard of care for treatment of CRSwNP provided the participant is stable on that treatment for 30 days prior to visit 1 4. Documented treatment of nasal polyposis exacerbation with SCS for at least 3 consecutive days or one IM depo-injectable dose (or contraindications/intolerance to) within the past 12 months prior to Visit 1 but not within the last 3 months prior to visit 1 and/or any history of NP surgery (or contraindications/intolerance to)
Additional criteria to be checked prior to randomisation (Visit 3) 1. Confirmed central reading total NPS ≥ 5 (≥ 2 for each nostril) at Visit 2 2. Bi-weekly mean NCS≥ 2 (baseline bi-weekly mean score collected from study Day -13 to study Day 0) 3. SNOT-22 score ≥ 30 at randomisation (Visit 3) 4. At least 8 days of evaluable daily diary data in the 14-day period prior to randomisation (baseline bi-weekly mean score collected from study Day – 13 to study Day 0) 5. 5. Subjects must have demonstrated a minimum 70% compliance with diary completion during the screening and run-in periods from Visit 1 to Visit 3.. 6. At least 70% compliance with the participant’s background INCS as captured in the eDiary during the screening and run-in periods from Visit 1 to Visit 3. |
|
E.4 | Principal exclusion criteria |
1. Any clinically important comorbidities other than asthma (e.g. active lung infection, bronchiectasis, pulmonary fibrosis, cystic fibrosis, primary ciliary dyskinesia, allergic bronchopulmonary mycosis, hypereosinophilic syndromes, etc.) that could confound interpretation of clinical efficacy results.
2. Sinus surgery within 6 months of screening visit OR any sinus surgery in the past which changed the lateral wall of the nose making NPS evaluation impossible.
3. Positive COVID-19 PCR test (or COVID-19 rapid test) or COVID-19 entry screening questionnaire during the screening visit. Evaluation will be based on local standard of care as determined by current local guidelines
4. Regular use of decongestants (topical or systemic) at enrolment is not allowed unless used for endoscopic procedure.
5. Use of immunosuppressive medication (including but not limited to: methotrexate, troleandomycin, cyclosporine, azathioprine, mycophenolate, tacrolimus, gold, penicillamine, sulfasalazine, hydroxychloroquine, systemic corticosteroids for condition or any experimental anti-inflammatory therapy) within 3 months prior to Visit 1 and during the study period. Systemic corticosteroid use is defined as treatment with a burst of systemic corticosteroids for at least 3 consecutive days or a single IM depo-injectable dose of corticosteroids (considered equivalent to a 3-day burst of systemic corticosteroids)
6. Receipt of COVID-19 vaccine (regardless of vaccine delivery platform) 28 days prior to date of IP administration at V3 (randomisation visit).

E.5 End points |
E.5.1 | Primary end point(s) |
Change from baseline in total NPS evaluated by nasal endoscopy at Week 52 and Change from baseline in bi-weekly mean NC score (NCS) evaluated as part of the Nasal Polyposis Symptom Diary (NPSD) at Week 52. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Key Secondary Endpoints:
At Week 52, change from baseline in bi-weekly mean loss of smell evaluated as part of the NPSD, change from baseline in SNOT-22 scores, change from baseline in Lund Mackay score (LMK) evaluated by CT, change from baseline in bi-weekly mean NPSD TSS, and change from baseline in pre-BD FEV1.
Time to surgery decision and/or SCS for NP, time to NP surgery decision and time to SCS for NP up to Week 52.
Other Secondary Endpoints:
Through Week 52, change from baseline over time in NPS evaluated by nasal endoscopy, change from baseline over time bi-weekly mean NCS evaluated by NPSD, change from baseline by domain of NPSD, and change from baseline in NPIF.
At Week 52, proportion of participants with (i) ≥1 point reduction and (ii) ≥2 points reduction in NPS, change from baseline in loss of smell evaluated by UPSIT test, change from baseline in modified LMK score evaluated by CT, sinus severity score by quantitative CT assessment, and change from baseline in ACQ-6. Exposure of SCS over 52 Weeks.
