Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Males or females, aged between 18 to 80 years, inclusive
  • The patient has received verbal and written study information, all questions have been answered satisfactorily and a consent form has been personally signed and dated by the patient and the investigator
  • A diagnosis of obstructive lung disease (with reference to the - International Primary Care Respiratory Group (IPCRG) Guidelines)(4). This being evidenced as a post bronchodilator ratio of FEV1/FVC < 0.7 at Visit 1 or 2 The patient has a post bronchodilator FEV1 of greater than 40% and less than 80% at Visit 1 or 2
  • Patients have a history of regular sputum production (> 3 days per week)
  • LCQ score of <17 (higher score indicates improvement).
  • A MRC dyspnoea score of 3 or more
  • Females must be post menopausal (> 1 year), surgically sterilised or using adequate hormonal contraception, intrauterine device), not breast feeding and have a negative serum pregnancy test
  • The patient must have a satisfactory health with the exception of obstructive lung disease as determined by the investigator on the basis of medical history and physical examination
  • In the Investigator's judgement, the patient is able and willing to comply with study visits and procedures (including laboratory tests, lung function tests).
  • Subjects must be able to demonstrate ability to use salbutamol MDI during the screening period

Exclusion Criteria:

  • The patient has currently poorly controlled disease defined as requiring a course of oral or parenteral corticosteroids or an exacerbation of their obstructive lung disease in the three months prior to Visit 2.
  • The patient has had a recent change in maintenance therapy (i.e. within 6 weeks)
  • Maintenance oral corticosteroid treatment or use of unlicensed doses of inhaled corticosteroid medication (>2000mcg beclomethasone diproprionate/ day or equivalent)
  • The patient has seasonal disease alone
  • The patient has any known laboratory abnormality, which in the opinion of the investigator, would contraindicate study participation, including, aspartate aminotransferase (AST) or alanine aminotransferase (ALT)greater/equal to 1.5 x upper limit of normal (ULN) or creatinine > 1.5 mg/dL
  • The patient is unable to discontinue short-acting beta-2-adrenergic agonists for at least 4 hours, long-acting beta agonists (12 hours) and tiotropium (24 hours) prior to Visit 2 (Week 0)
  • The patient has chronic heart failure class III or IV (New York Heart Association) or a recent (less than six months) history of stroke, transient ischemic attack or myocardial infarction
  • The patient is not able to follow study procedures (e.g., language problems, psychological disorders) or is considered to be non-compliant according to the investigator.
  • The patient has a history of known alcohol or substance abuse (excluding cigarettes) within the one-year prior to Visit 1
  • The patient has an active malignancy of any type or history of a malignancy (with the exception of patients with malignancy surgically removed with no evidence of recurrence within five years before enrolment, and patients with history of treated basal cell carcinoma)
  • The patient has any other severe or acute or chronic medical or psychiatric conditions that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study. Subjects with a malignancy and who are currently undergoing radiation therapy or have had chemotherapy within 5 years.
  • The patient has difficulty swallowing capsules or tablets, dysphagia or is unable to tolerate oral medication
  • The patient has been previously admitted to the study or currently participating or have recently participated in another trial with an investigational drug within 90 days of the start of this study.

5. Study Description

Brief Summary
Obstructive airways disease is a very common condition. This condition includes patients with asthma, chronic obstructive pulmonary disease (COPD), emphysema or chronic bronchitis. Some patients with obstructive airways disease have problems with long term breathlessness, wheeze and cough with or without sputum production. Currently the researchers give treatments - usually inhalers - which are designed to open the airways and reduce the breathlessness and wheeze. Despite these available treatments many patients still have continuing symptoms. Anecdotal clinical evidence suggested that a herbal remedy (called AKL1) has beneficial effects in respiratory conditions, with patients diagnosed as having both asthma and COPD reporting reduced symptoms including breathlessness and cough and reduced frequency of attacks.The purpose of this study is to confirm whether AKL1 does indeed have a meaningful benefit to patients with obstructive airways disease. The researchers will mainly be measuring any effect of AKL by assessing any change in trial subjects' coughs, using a questionnaire, but the researchers will also looking at breathing tests, walking tests, blood and sputum tests.
Detailed Description
The outcomes of care for obstructive airways disease in the UK and other countries fail to meet guideline targets, with high levels of avoidable morbidity and avoidable mortality. Obstructive lung disease is an encompassing term for a condition that includes patients with a reversible (asthma) or non reversible (chronic obstructive pulmonary disease) component to their lung function. AKL1 is a novel pharmaceutical agent derived from a combination of botanical products developed as a treatment for obstructive lung disease (asthma and COPD). The botanical product contains a synthetically-derived phytochemical component of Picrorrhiza kurroa, apocynin, together with standardized extracts of Picrorrhiza kurroa, Zingiber officinale and Ginkgo biloba that have previously been marketed as a health food supplements. Recent evidence suggests that Ginkgo biloba reduces inflammatory (protein kinase C positive ie eosinophils and neutrophils) cells in induced sputum which given in addition to inhaled corticosteroids to asthmatic patients. Anecdotal clinical evidence suggests that the botanical product has significant activity in respiratory conditions, with patients diagnosed as having obstructive lung disease (asthma and COPD) reporting reduced symptoms including breathlessness and cough, reduced frequency of attacks, reduced dependence on bronchodilators and ability to reduce inhaled corticosteroids dose. We have completed a pilot study investigating the efficacy and safety of AKL1 as 'add-on' therapy for adult patients diagnosed as having obstructive lung disease whose symptoms remained uncontrolled on standard medication. Whilst there was no significant differences in lung function, there were trends to clinical improvements in the patient-centered outcomes e.g. cough, health status and exacerbation frequency. Hence a larger adequately powered study is needed to investigate these outcomes further.
