Clinical Trial Summary

Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.

Description:

Study Drug Indication: - Treatment of HRV infections in patients with COPD Study Rationale: An effective, easily administered therapy for RV infection would have the potential to reduce the serious health effects in vulnerable populations, such as those with COPD. Treatment of RV infection could reduce the severity and frequency of acute COPD exacerbations, preserve pulmonary function, prevent secondary bacterial infections, and mitigate the need for costly medical interventions, including inhaled agents, steroids, antibacterial drugs, emergency treatment, hospitalization, and mechanical ventilation. Thus, early treatment of acute COPD exacerbations related to RV infection could potentially improve both the quality of life and longevity of COPD patients. Altesa BioSciences, Inc. is developing drugs to treat RV and other respiratory virus infections. VPV has been shown to inhibit RV in vitro and in human clinical trials. Furthermore, VPV has been administered to more than 650 study participants and has been well-tolerated. Based on its potential to prevent severe respiratory complications, Altesa BioSciences, Inc is continuing the development of this drug for the treatment of RV infection. Study Dose justification: - In patients with asthma, vapendavir doses of 264 mg bid and 528 mg bid were utilized and demonstrated reduced viral load and was well tolerated. - A PK study established the pharmacokinetics of a free based micronized tablet in achieving adequate plasma levels after a single dose in fed adults. Study Treatment Duration: - 7 days End of Study: - Up to 63 days, including the screening and follow-up periods. Study Centers: - There will be 1 study centre, ICRRU within Imperial College Healthcare NHS site at St Mary's Hospital London, United Kingdom. Study Treatment: - 1:1 randomization to Vapendavir 500mg bid or placebo Study Procedures: - Screening period (Pregnancy test for females, Lung function tests (FEV1, FVC, PEF), Height and Weight/BMI Calculation, Physical Examination, Vital Signs, Medical and Surgical history, Blood sample, COPD assessment test) - Baseline visit to clinic (Pregnancy test for females, Physical examination, Safety assessments, Vital Signs, Concomitant medication assessment, Nasal lavage/nasosorption, Chest X-Ray, ECG, Blood for hematology, biochemistry and liver function tests, Induced Sputum, Lung Function Tests (FEV1, FVC, PEF)) - Clinical Visit Day 1 (Randomization to treatment, Dispense Medication, Physical Examination, Safety Assessments, Vital Signs, Concomitant medication assessment, Nasal lavage/nasosorption, Chest X-Ray, ECG, Blood for hematology, biochemistry and liver function tests, Induced Sputum, Lung Function Tests (FEV1, FVC, PEF), Intranasal RV-A16 challenge) - Treatment Commencement-Clinical Visit Days 1-28 (Physical Exam, Safety Assessments, Vital Signs, Concomitant Medication and food assessments, Diaries and eCRF completion, Treatment twice daily (If required), Drug Compliance, Nasal Lavage/nasosorption, Blood serum for biomarkers, Blood for hematology and biochemistry, Blood for PK, Pregnancy test for females, Lung Function Tests (FEV1, FVC, PEF)) - Treatment Commencement-Clinical Visit Day 42 (Physical Examination, Safety Assessments, Vital Signs, Concomitant medication and food assessments, Diaries and eCRF completion, Nasal lavage/nasosorption, Blood serum for biomarkers, blood for hematology, biochemistry and liver function tests, Blood sample taken to assess RV-A16 sero-positivity, Pregnancy test for females, Lung Function Tests (FEV1, FVC, PEF)) - Early Termination Visit (Physical Examination, Safety Assessments, Vital Signs, Concomitant medication and food assessments, Diaries and eCRF completion, Nasal lavage/nasosorption, Blood Serum for Biomarkers, Blood for hematology and biochemistry, Blood for PK, Sputum - Unscheduled Visit (Physical Examination, Safety Assessments, Vital Signs, Concomitant medication and food assessments, Diaries and eCRF completion, Drug complicance, Lung function tests (FEV1, FVC, PEPF), Blood or PK-morning (or sampling)) - Study drug administered as soon as possible after onset of symptoms and documentation of HRV infection, but no greater than 48 hours after symptom onset. Study Sample Size: • 50 participants randomization will be 1:1 VPV : placebo. Participants will undergo 7 days of twice daily treatment. Treatment will commence after symptom onset or when the participant determines they have a clinical cold. Statistical Methods: - Efficacy Analysis: All participants infected and treated will comprise the infected and evaluable population and be included in the efficacy analysis (primary, secondary, exploratory endpoints). Subjects inoculated but not successfully infected will not be included in this analysis. - Safety Analysis: All participants that have undergone any treatment with VPV or placebo will comprise the safety population and will be included in the safety analysis. Subjects that are inoculated, treated but not successfully infected will be included in this population. - Inoculated & Followed-Up Population: Participants that are inoculated, but that do not fit the criteria to undergo treatment or become pregnant will be followed up until Day 42 ± 2. This group will be composed of both uninfected and successfully infected participants and follow up will be to obtain data on the RV challenge model, COPD related symptoms and also for safety reasons. - Statistical Analysis Plan: A comprehensive Statistical Analysis Plan (SAP) will be finalized prior to reporting of the study results. The SAP may modify the plans outlined in the protocol; however, any major modifications of planned analyses will be reflected in a protocol amendment.

Eligibility

Inclusion Criteria:

1. Male or female age =40 years and =75 years at the time of signing the informed consent form.

2. If sexually active and/or of child-bearing potential (both females and males), must agree to use a highly effective forms of contraception = 28 days prior to the first dose (females), during the study period (both males and females) and for 30 days (females) or 90 days (males) after the last dose. A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. Highly effective contraception is defined as methods that can achieve a failure rate of less than 1% per year when used consistently and correctly. Males (including those with a vasectomy): agree to use a condom and if a female partner of childbearing potential, use of at least one other contraceptive method; males must also agree not to donate sperm within 90 days after the last dose). WOCBP participants must use at least one highly effective contraceptive method.

Birth control methods which may be considered as highly effective:

• Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation
• oral
• intravaginal
• transdermal
• progestogen-only hormonal contraception associated with inhibition of ovulation
• oral
• injectable
• implantable
• intrauterine device (IUD)
• intrauterine hormone-releasing system ( IUS)
• bilateral tubal occlusion
• vasectomised partner

3. Confirmed diagnosis of Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) stage II COPD as defined by % predicted Forced expiratory volume in 1 second (FEV1) =50% and FEV1/Forced vital capacity (FVC) <70%.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Peak change from baseline	• Evaluation of the peak total lower respiratory symptom score (LRSS) in participants administered with VPV relative to/versus (vs) placebo as determined by Mallia et al (Am J Respir Crit Care Med. 2011) from day of treatment commencement until Day 42. This is a measure of a number of lower respiratory symptoms in a 24 hour period that include: shortness of breath (scale 0-4; 0 = not breathless, 4 = breathless at rest) wheeze (0-4; 0 = no wheeze, 4 = wheeze at rest), cough (0-3; 0 = no cough, 3 = severe cough), sputum quantity (0-3; 0 = none, 3 = large volume , more than 100 ml) sputum quality (0-3; 0 = none, 3 = purulent, green in colour). The total lower respiratory symptom score is the sum of all the above measurements (minimum 0, maximum 17) recorded on each day. These values will be recorded via a study diary over a six week period (day 0-42). Peak value is the highest daily total value over the 6 week post-infection period.	From Baseline Visit through Follow-Up Visit, up to 7 weeks
Secondary	Peak COPD Specific Respiratory Symptoms	The Exacerbations of Chronic obstructive disease Tool-Respiratory Symptoms (EXACT-RS), out of 40 and EXACT-PRO, out of 51. Each questionnaire asks questions about severity of symptoms and impact on daily tasks (reach scored 0-3 or 0-4, 0=not at all, 3 or 4=extremely.	Day of treatment commencement to Day 42
Secondary	Peak Upper Respiratory Symptoms	Jackson Score as measured by Mallia et al (Am J Respir Crit Care Med. 2011). A modified Jackson score will be utilized which assesses the following eight upper respiratory symptoms daily: nasal congestion, runny nose, sneezing, cough, sore throat, general malaise, headache, chilliness (each scored 0-3 where 0 = none, 3 = severe). Minimum daily score= 0, maximum daily score= 24.	Day of treatment commencement to Day 42
Secondary	Peak Overall Symptom severity	Patient global impression of severity (PGIS) The PGIS asks one question on disease severity and is scored from 0-3 (0=none, 3=severe); Patient global impression of change (PGIC). The PGIC asks one question on how symptoms have changed from yesterday (-3 to +3 where -3= much worse, 0=no change and +3= much better).	Day of treatment commencement to Day 42
Secondary	Peak Virus Load as measured in RNA copies per mL	Nasal lavage virus load; Sputum virus load	Day of treatment commencement to Day 42
Secondary	Peak Sputum Bacterial Load	Total 16SrRNA as measured in DNA copies per mL; Moraxella catarrhalis as measured in DNA copies per mL; Streptococcus pneumoniae as measured in DNA copies per mL; Haemophilus influenzae as measured in DNA copies per mL; Bacterial load as measured in pfu per mL by NHS microbiology culture	Day of treatment commencement to Day 42
Secondary	Maximum Change in Forced Expiratory Volume in 1 Second (FEV1)	FEV1 as measured in L/second; FEV1 as measured in % predicted from L/second	Day of treatment commencement to Day 42
Secondary	Maximum Change in Forced Vital Capacity	Forced Vital Capacity (FVC) as measured in L; FVC as measured in % predicted from L	Day of treatment commencement to Day 42
Secondary	Maximum Change in FEV1/FVC	FEV1/FVC ratio in L	Day of treatment commencement to Day 42
