This study evaluates the safety and efficacy of the inhaled drug GSK2269557, compared with placebo, and changes in sputum and blood biomarkers in people with chronic obstructive pulmonary disease (COPD) who are having an acute exacerbation. Patients aged 40 to 80 with an established COPD diagnosis for at least 6 months and an acute exacerbation requiring corticosteroids and antibiotics may take part. The study was conducted in Phase 2 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.

Postmenopausal defined as 12 months of spontaneous amenorrhea. Females whose menopausal status is in doubt will be required to use, or have been using, one of the highly effective contraception methods as specified below from 30 days prior to the first dose of study medication and until completion of the follow-up visit. 2)Reproductive potential and agrees to follow one of the options listed below in the GlaxoSmithKline (GSK) Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study medication and until completion of the follow-up visit. GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in FRP. This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long term and persistent basis. 1) Contraceptive subdermal implant that meets GSK standard criteria including a \<1% rate of failure per year, as stated in the product label. 2) Intrauterine device or intrauterine system that meets GSK standard criteria including a \<1% rate of failure per year, as stated in the product label. 3) Oral Contraceptive, either combined or progestogen alone. 4) Injectable progestogen. 5) Contraceptive vaginal ring. 6) Percutaneous contraceptive patches. 7) Male partner sterilization with documentation of azoospermia prior to the female subject's entry into the study, and this male is the sole partner for that subject. 8) Male condom combined with a vaginal spermicide (foam, gel, film, cream, or suppository). These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception. Specific inclusion criteria for Male subjects with female partners of reproductive potential is outlined below: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until after the completion of the follow up visit. 1) Vasectomy with documentation of azoospermia. 2) Male condom plus partner use of one of the contraceptive options below: Contraceptive subdermal implant that meets GSK standard criteria including a \<1% rate of failure per year, as stated in the product label. Intrauterine device or intrauterine system that meets GSK standard criteria including a \<1% rate of failure per year, as stated in the product label. Oral Contraceptive, either combined or progestogen alone. Injectable progestogen. Contraceptive vaginal ring. Percutaneous contraceptive patches. These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception. * Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in this protocol. Exclusion Criteria: * To avoid recruitment of subjects with a severe COPD exacerbation, the presence of any one of the following severity criteria will render the subject ineligible for inclusion in the study: Need for invasive mechanical ventilation (short term \[\<48 hour\] Non-invasive ventilation \[NIV\] or continuous positive airway pressure \[CPAP\] is acceptable); Haemodynamic instability or clinically significant heart failure; Confusion; Clinically significant pneumonia, identified by chest X-ray at screening, and as judged by the Investigator. * Subjects who have current medical conditions or diseases that are not well controlled and, which as judged by the Investigator, may affect subject safety or influence the outcome of the study. (Note: Patients with adequately treated and well controlled concurrent medical conditions (e.g. hypertension or noninsulin-dependent diabetes mellitus \[NIDDM\]) are permitted to be entered into the study). * Subject has a diagnosis of active tuberculosis, lung cancer, clinically overt bronchiectasis, pulmonary fibrosis, asthma or any other respiratory condition that might, in the opinion of the investigator, compromise the safety of the subject or affect the interpretation of the results. * ALT \>2xupper limit of normal (ULN) and bilirubin \>1.5xULN (isolated bilirubin \>1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%). * A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the exclusion criteria, outside of the reference range for the population being studied may be included if the Investigator \[in consultation with the GSK Medical Monitor if required\] documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. * Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones) * ECG indicative of an acute cardiac event (e.g. Myocardial Infarction) or demonstrating a clinically significant arrhythmia requiring treatment. * QTcF \> 450 msec or QTcF \> 480 msec in subjects with Bundle Branch Block, based on single QTcF value. * Subjects who have undergone lung volume reduction surgery. * Subject is currently on chronic treatment with macrolides or long term antibiotics. * Subject is being treated with long term oxygen therapy (LTOT) (\>15 hours/day). * The subject has been on chronic treatment with anti-Tumour Necrosis Factor (anti-TNF), or any other immunosuppressive therapy (except corticosteroid) within 60 days prior to dosing * History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of \>28 units for males or \>21 units for females. One unit is equivalent to 8 gram (g) of alcohol: a half-pint (\~240 milliliter \[mL\]) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits. * History of sensitivity to any of the study medications, or components thereof (such as lactose) or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation. * A known (historical) positive test for human immunodeficiency virus (HIV) antibody. * Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment. NOTE: Because of the short window for screening, treatment with GSK2269557 may start before receiving the result of the hepatitis tests. If subsequently the test is found to be positive, the subject may be withdrawn, as judged by the Principal Investigator in consultation with the Medical Monitor. * Where participation in the study would result in donation of blood or blood products in excess of 500 mL within 56 days. * The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer). * Exposure to more than 4 investigational medicinal products within 12 months prior to the first dosing day.
