Clinical Trial Summary

The aim of the study is to assess the safety of inhaled SNG001 and the ability of inhaled SNG001 to 'switch on' the cells' anti-viral defences in patients with chronic obstructive pulmonary disease (COPD). The study consist of two parts. Part 1 will assess the safety of inhaled SNG001 in ten patients with stable COPD. Part 2 will assess efficacy and safety of inhaled SNG001 in 120 patients with COPD with a cold or COPD exacerbation.

Description:

When people with COPD get a respiratory virus such as a cold or flu it often increases their COPD symptoms, leading them to require treatment with either antibiotics or oral steroids and severely affecting their quality of life. SNG001 is the study medication, and it contains interferon beta (interferon-β) which is a natural antiviral protein. In this study we will look to see whether inhaled SNG001 can boost anti-viral responses and minimise the worsening of COPD symptoms/lung function when patients have a confirmed respiratory virus. In Part 1 ten COPD patients without a respiratory virus will be randomised to receive three days of SNG001 or placebo. The aim of this part of the study is to assess safety of SNG001 in COPD patients. In Part 2 COPD patients will contact the research team when they experience cold or flu symptoms or a deterioration of their COPD symptoms. At this point, eligible patients will undergo a virus detection test and those that test positive for a virus will be randomised 1:1 to receive SNG001 or placebo once daily for 14 days. The first dose of study medication will be administered within 48 hours. Other assessments will be performed during the 14 days of treatment to look for changes in anti-viral biomarkers, lung function and COPD symptoms. Patients will also be followed up 14 days post end of treatment.

Eligibility

PART 1 - Inclusion Criteria:

1. Male or female, between and including 40-75 years of age, at the time of the screening visit.

2. A confirmed physician diagnosis of COPD or a medical history consistent with a diagnosis of COPD for at least 12 months prior to the screening visit.

3. Post-bronchodilator FEV1 =40% of predicted and FEV1/FVC ratio <0.7 (at screening).

4. FEV1 =30% of predicted (at Visit 2, pre-dose).

5. Should have stable COPD, having no symptoms of an exacerbation and/or respiratory tract infection currently and/or within the past 6 weeks of screening and/or randomisation.

6. Should be prescribed and taking regularly one or more long acting bronchodilators (e.g. long acting ß2 agonist [LABA], long acting muscarinic antagonist [LAMA]) with or without an inhaled corticosteroid maintenance therapy for their COPD.

7. Patients who produce sputum most days.

8. Provide written informed consent.

9. The patient produced an adequate sputum sample at the screening visit.

10. Female patients must be 1 year post-menopausal, surgically sterile, or using an acceptable method of contraception. Women should have been stable on their chosen method of birth control for a minimum of 3 months before entering the trial and should continue with birth control for 1 month after the last dose. In addition to the acceptable birth control method (except for the practice of total sexual abstinence), condom (in UK with spermicides) should be used by the male partner for sexual intercourse from randomisation (Visit 2) and for 1 month after the last dose to prevent pregnancy. Women of childbearing potential must have a negative pregnancy test at screening and prior to randomisation. Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrheic for 12 months prior to the planned date of randomisation without an

alternative medical cause. The following age specific requirements apply:

• Women <50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and if follicle stimulating hormone (FSH) levels are in the postmenopausal range. If the FSH result is not available at the time of randomization, the patient must have a negative pregnancy test and agree to use highly effective contraception methods until the FSH result is available.
• Women =50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.

11. Motivation (in the Investigator's opinion) to comply with protocol requirements and complete all study visits, including the ability to communicate well with the Investigator and be capable of understanding the nature of the research and its treatment (including its risks and potential benefits).

PART 2 - pre-treatment Inclusion Criteria:

1. Male or female, between and including 40-85 years of age at the time of the consent visit.

2. A confirmed physician diagnosis of COPD or a medical history consistent with a diagnosis of COPD for at least 12 months prior to the consent visit.

3. Current or ex-smoker with = 10 pack years of smoking history.

4. Post bronchodilator FEV1/FVC ratio <0.7.

5. Post bronchodilator FEV1 =40% of the predicted value. Once the safety data for the first 16 patients have been reviewed and approved by the DSMC the criterion will be changed to a post bronchodilator of FEV1 =30% of the predicted value*.

6. To have had 1 or more COPD exacerbations in the last 12 months requiring intervention with oral corticosteroids and/or antibiotics.

7. Patient reported evidence that a respiratory virus has made their COPD significantly worse in the past.

8. Should be prescribed and taking regularly one or more long acting bronchodilator (e.g. long acting ß2 agonist [LABA], long acting muscarinic antagonist [LAMA]) with or without an inhaled corticosteroid maintenance therapy for their COPD.

9. Patients on self-management plans agree to consult a healthcare professional prior to taking oral corticosteroids or antibiotics for treatment of a COPD exacerbation.

10. Provide written informed consent.

11. Be the owner of a mobile phone, and be able to, and agree to, respond to the required SMS (text) messages for the trial.

12. Female patients must be 1 year post-menopausal, surgically sterile, or using an acceptable method of contraception.

Women should have been stable on their chosen method of birth control for a minimum of 3 months before entering the trial and should continue with birth control for 1 month after the last dose of inhaled IFN-ß-1a/matching placebo. In addition to the acceptable birth control method (except for the practice of total sexual abstinence), condom (in UK with spermicides) should be used by the male partner for sexual intercourse from randomisation (Visit 2) and for 1 month after the last dose of inhaled IFN-ß-1a/matching placebo to prevent pregnancy. Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrheic for 12 months prior to the planned date of randomisation without an

alternative medical cause. The following age specific requirements apply:

• Women <50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and if FSH levels are in the postmenopausal range.
