Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacogenetic, Pharmacoeconomic, Therapy, Dose response, Pharmacokinetic, Pharmacogenomic, Safety, Pharmacodynamic, Efficacy

To evaluate the effect of 2 dose regimens of tozorakimab as addon to standard of care compared with standard of care plus placebo on the rate of moderate to severe exacerbations in former smokers.

Secondary objectives 3

1. 1. To evaluate the effect of 2 dose regimens of tozorakimab as addon to standard of care compared with standard of care plus placebo on: a) the rate of moderate to severe COPD exacerbations in former and current smokers b) change in pre-bronchodilator lung function c) change in post-bronchodilator lung function d) respiratory symptoms e) respiratory health status/health related quality of life f) time to moderate to severe COPD exacerbations g) severe COPD exacerbations h) COPD health status/health-related quality of life i) COPD-related healthcare resource utilization j) daily rescue medication use
2. 2.To evaluate the pharmacokinetics and immunogenicity of 2 dose regimens of tozorakimab.
3. 3. To assess the safety and tolerability of two dose regimen of tozorakimab as add on to standard of care compared with standard of care plus placebo.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 7

1. 1. Participant must be ≥ 40 years of age and capable of giving signed informed consent.
2. 2. Documented diagnosis of COPD for at least one year prior to enrolment.
3. 3. Post BD FEV1/FVC < 0.70 and post-BD FEV1 >20% of predicted normal value.
4. 4. Documented history of ≥ 2 moderate or ≥ 1 severe COPD exacerbations within 12 months prior to enrolment.
5. 5. Documented optimized inhaled dual or triple therapy at a stable dose for at least 3 months prior to enrolment.
6. 6. Smoking history of ≥ 10 pack-years.
7. 7. CAT total score ≥ 10, with each of the phlegm (sputum) and cough items with a score ≥ 2

Exclusion criteria 18

1. 1. Clinically important pulmonary disease other than COPD.
2. 2. Radiological findings suggestive of a respiratory disease other than COPD that is significantly contributing to the participant’s respiratory symptoms. Radiological findings of pulmonary nodules suspicious for lung cancer, as per applicable guidances, without appropriate follow up prior to randomisation. Radiological findings suggestive of acute infection.
3. 3. Current diagnosis of asthma, prior history of asthma, or asthma-COPD overlap. Childhood history of asthma is allowed and defined as asthma diagnosed and resolved before the age of 18.
4. 14. Malignancy, current or within the past 5 years, except for adequately treated non-invasive basal cell and squamous cell carcinoma of the skin and cervical carcinoma-in-situ treated with apparent success more than one year prior to enrolment. Suspected malignancy or undefined neoplasms.
5. 4. Any unstable disorder, including, but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric disorder, major physical and/or cognitive impairment that could affect safety, study findings or participants ability to complete the study.
6. 5. COPD exacerbation, within 2 weeks prior to randomization, that was treated with systemic corticosteroids and/or antibiotics, and/or led to hospitalization.
7. 6. Active significant infection within the 4 weeks prior to randomization, pneumonia within 6 weeks prior to randomization, or medical condition that predisposes the participant to infection.
8. 16. Participants that have previously received tozorakimab.
9. 13. Evidence of active liver disease, including jaundice during screening.
10. 7. Suspicion of, or confirmed, ongoing SARS-CoV-2 infection.
11. 8. Significant COVID-19 illness within the 6 months prior to enrolment.
12. 12. History of positive test or treatment for hepatitis B or hepatitis C (except for cured hepatitis C)
13. 9. Unstable cardiovascular disorder.
14. 15. Participants who have evidence of active TB.
15. 11. History of known immunodeficiency disorder, including a positive test for HIV-1 or HIV 2.
16. 10. Diagnosis of cor pulmonale, pulmonary arterial hypertension and/or right ventricular failure.
17. 17. Any clinically significant abnormal findings in physical examination, vital signs, ECG, or laboratory testing during the screening period, which in the opinion of the investigator may put the participant at risk because of their participation in the study, or may influence the results of the study, or the participant’s ability to complete the entire duration of the study.
18. 18. Active vaping of any products or using smoked marijuana within the 6 months prior to randomization and during the study.
