General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study is to assess the effects of MEDI3506 compared with placebo on pulmonary function in participants with chronic obstructive pulmonary disease (COPD) and chronic bronchitis.
|
||
Protection of trial subjects |
The conduct of this clinical study met all local and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and are consistent with International Conference on Harmonization guideline: Good Clinical Practice, and applicable regulatory requirements. Participants signed an informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.
|
||
Background therapy |
Participants who have a documented stable regimen of dual therapy or triple therapy for >= 3 months prior to enrollment; there should have been no change in treatment after the previous exacerbation prior to entering into the study. Where dual therapy consists of inhaled corticosteroids (ICS) + long-acting beta 2 agonist (LABA) or LABA + long-acting muscarinic receptor antagonist (LAMA), and triple therapy consists of ICS + LABA + LAMA. Both dual and triple therapy may be in the form of separate inhalers of fixed dose combination inhalers but may not be in nebulized form. | ||
Evidence for comparator |
Itepekimab, a monoclonal antibody targeting IL-33, demonstrated clinical activity in asthma, with potential in chronic obstructive pulmonary disease (COPD). In the Phase 2 study, primary endpoint exacerbation rate was not met. Subgroup analysis showed that itepekimab reduced exacerbation rate and improved lung function in former smokers with COPD (Rabe et al. Lancet Respir Med 2021;9: 1288–98). Astegolimab, a selective ST2 IgG2 monoclonal antibody did not significantly reduce exacerbation rate in the Phase 2 study, but did improve health status compared with placebo (Yousuf et al. Lancet Respir Med 2022; 10: 469–77). | ||

End point description |
Change from baseline to Week 12 in 4-weekly mean E-RS:COPD total score is reported. The E-RS™:COPD is an 11-item electronic patient reported outcome (ePRO) questionnaires developed to evaluate the severity of respiratory symptoms of COPD including breathlessness (5 items; score range: 0 to 17), cough and sputum (3 items; score range: 0 to 11), and chest symptoms (3 items; score range: 0 to 12). The ePRO was completed every day at home and at site visits. Summation of E-RS:COPD item responses produced a total score ranging from 0 to 40, with higher scores indicating greater severity. The 4-weekly mean will be calculated as the sum of all non-missing daily scores over the 28-day evaluation period, divided by the number of non-missing daily scores. ITT population included all participants who received any study drug and were analyzed according to the treatment they actually received.

Change from baseline to Week 12 in mean BCSS score (over the previous 4 weeks) is reported. The BCSS was a 3-item daily diary that assesses the severity of the 3 symptoms: breathlessness, sputum, and cough, each on a 5-point Likert scale ranging from 0 (no symptoms) to 4 (severe symptoms). Item scores were summed to yield a total score ranging from 0 to 12; wherein higher total score indicated more severe symptoms. The BCSS was captured each evening via eDiary. The 4-weekly mean BCSS score was calculated as the sum of all non-missing daily scores over the 28-dayevaluation period, divided by the number of non-missing daily scores. ITT population included all participants who received any study drug and were analyzed according to the treatment they actually received.

Change From Baseline to Week 12 in Airwave Oscillometry (AO) Parameters | |||||||||||||||||||||
End point description |
Change from baseline to Week 12 in AO parameters including frequency dependence of resistance at 5-20 Hz (R5-R20) and respiratory resistance at 5 Hz (R5; total airway resistance) and 20 Hz (R20; resistance of large airways) is reported. AO is a non-invasive lung function test assessed using an AO device. It is assessed during quiet, tidal breathing with no participant effort required, by superimposing a multi-frequency oscillation onto the participant's natural breathing. AO device uses a vibrating mesh to generate a multifrequency sinusoidal pseudorandom noise (PRN) signal. The AO markers; respiratory resistance at 5 Hz (R5) and 20 Hz (R20) and difference between resistance at 5 and 20Hz (R5-R20; resistance in small airways) are recorded. These markers measure peripheral airway resistance. ITT population: all participants who received any study drug and were analyzed according to received treatment. Number of participants analyzed: participants who were evaluable at Week 12.

End point description |
An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Adverse event of special interest (AESI) are AEs of scientific and medical interest specific to understanding of tozorakimab and requires close monitoring. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug. As-treated population included all participants who received any study drug and were analyzed according to the treatment they actually received.

Adjustments regarding timing of repeat attempts in case of failure to successfully obtain spontaneous and induced sputum samples. Added text regarding participants who met eligibility criteria for main study but not sub study and clarification regarding quantitative assessment of computerized tomography (CT) scan showing emphysema in Exclusion Criterion 4 (c). Criteria for discontinuation amended. Added detail regarding how the echocardiogram should be performed and urine specific gravity to Table 8 (Laboratory Safety Variables) in protocol. ‘Hepatitis A’ was removed from other safety tests. Intensity Rating Scale was replaced with Severity Rating Scale based on the common terminology criteria for adverse events (CTCAE) criteria. |

Removed Exclusion Criterion 4 (predominant emphysema). Section 2.2 (Background), Section 2.3.1 (Risk Assessment) and Section 5.2 (Scientific rationale for study design) updated with new emerging evidence and rationale for update. Added additional secondary and exploratory objective to assess response to tozorakimab by extent of emphysema on baseline CT scan. Reference to exclusion criteria for extent of emphysema removed. Added emphysema subgroup analysis for primary endpoint. Polymerase chain reaction (PCR) analysis changed to nucleic acid analysis. Added information that automated calculation of emphysema percentage was not possible. Changed timing of inclusion criterion 9 from >= 1 exacerbation of chronic obstructive pulmonary disease (COPD) in 12 months to >= 1 exacerbation in 24 months and updated rationale for study population to reflect this change. Changed BMI to 18-35 kg/m^2. Clarified wording on lung resection exclusion and testing. Clarification on testing for hepatitis C infection added. |

Amended participants randomization and number of evaluable participants. Updated new participant numbers, sample size justification in statistical method section. Clarified spirometry assessment timing. Added salivary sample as additional option for SARS-CoV-2 nucleic acid test. Updated risk assessment related to progression of heart failure. Revised CT risk mitigations. Removed Week 20 assessment of blood biomarkers and assessment of soluble receptor for advanced glycation end products (sRAGE) and fibronectin. mRNA nasal transcriptome exploratory biomarkers clarified as from nasal mucosal sampling. Week 36 assessment of serum biomarkers added. Updated number of participants to be randomized and expected percentage of participants in baseline and inhaled corticosteroids (ICS) strata removed. Added advice on ensuring adequate time for CT and echocardiogram assessments. Clarified use of eDiary and spirometry assessment timing. Reduced overall number of participants in the CT sub-study. Clarified when to perform echocardiogram in cases of suspected heart failure. Updated inclusion criterion 1, 3, 4, 5, 8, 9, 13, and exclusion criterions 1, 3a, 3c, 3e, 3f, 5, 9g, 24, 9e, 10, 15, 23, 34h, 34i, 34k, 41, and 43. Removed collection of spontaneous sputum samples from home. Phenotype monitoring details of participants removed. Reduced overall number of participants in CT sub-study to remain proportionate to reduced size of main study. Text around strata caps and safety alerts removed. Revised vaccination against influenza and pneumonia advice. Added baseline audiometry testing to be documented before randomization. Advice on spirometry assessment timing clarified. Dose of radiation in mSV removed. Revised text to add circumstances in which anti-drug antibody (ADA) samples could be collected after follow-up period. Reduced size of population in small CT exploratory sub-study to explore impact of tozorakimab on radiological biomarkers of airways inflammation and mucus plugging. |
