Dose Finding Study of Nemiralisib (GSK2269557) in Subjects With an Acute Moderate or Severe Exacerbation of Chronic Obstructive Pulmonary Disease (COPD)

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Pulmonary Disease, Chronic Obstructive

In brief

Nemiralisib is being developed as an anti-inflammatory drug for the treatment of inflammatory airways disease. This study is designed to assess the dose response, efficacy, safety, and pharmacokinetics of nemiralisib across a range of doses \[up to 750 micrograms (µg)\] compared with placebo. The study consists of a Screening Period, a 12-Week Treatment Period and a 12-Week Post-Treatment Follow-Up Period. Approximately 1,250 subjects with an acute moderate or severe exacerbation of COPD requiring standard of care (SoC) therapy will be randomized in this double-blind study. Subjects will be randomized to receive different doses of nemiralisib or placebo via ELLIPTA® inhaler. The total duration of study participation is approximately 6 months (170 days). ELLIPTA is the registered trademark of GlaxoSmithKline (GSK) group of companies.

Current or former cigarette smoker with a history of cigarette smoking of >=10 pack-years. Former smokers are defined as those who have stopped smoking for at least 6 months prior to Screening (Visit 1). Number of pack years = (number of cigarettes per day / 20) x number of years smoked).
Acute exacerbation of COPD requiring an escalation in therapy to include oral/systemic corticosteroid(s) (prednisone 40 mg/day or equivalent) for 5 days and antibiotic(s) for 7 days; the dose and/or duration of prednisone (40 mg/day or equivalent) and/or the antibiotic can be modified according to the Investigator's/medically qualified designee's judgment or according to local country/institution practice. Acute exacerbation to be confirmed by an experienced physician and to represent a recent worsening of at least two major and one minor symptoms, one major and two minor symptoms, or all 3 major symptoms. Major symptoms include subjective increase in dyspnea, increase in sputum volume or change in sputum color. Minor symptoms include increased cough, increased wheeze, sore throat, colds or fever (oral temperature >37.5 degree Celsius) without other cause.
Body weight >=45 kilogram (kg) and body mass index (BMI) within the range 16 - 35 kg per meter square (kg/m\^2) (inclusive)
Male and female subjects are eligible to participate in the study. A female subject is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: Not a woman of childbearing potential (WOCBP) or a WOCBP who agrees to follow the contraceptive guidance during the 12-Week Double-Blind Treatment Period and for at least 5 half-lives (10 days) after the last of double-blind study treatment.

You may not qualify if…

Moderate/severe exacerbation of COPD for which SoC was started >48 hours since diagnosis.
A chest X-ray [or computed tomography (CT) scan] that reveals evidence of clinically significant abnormalities not believed to be due to the presence of COPD. A chest X-ray (or CT scan) must be taken at Screening (Visit 1). For sites in Germany: if a chest X-ray (or CT scan) within 1 year of Screening (Visit 1) is not available, approval to conduct a diagnostic chest X-ray (CT scan) will need to be obtained from the Federal Office for Radiation Protection (BfS).

A diagnosis of alpha 1-antitrypsin deficiency as the underlying cause of COPD, active tuberculosis, lung cancer, clinically overt bronchiectasis (Note: focal bronchiectasis is not exclusionary), sarcoidosis, pulmonary fibrosis (Note: focal fibrotic pulmonary lesions are not exclusionary), primary pulmonary hypertension, interstitial lung diseases,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.
A history or current evidence of clinically significant and unstable disease such as cardiovascular (e.g., subjects requiring implanted cardioverter defibrillator [ICD], pacemaker requiring a rate set >60 beats per minute (bpm), uncontrolled hypertension, New Your Heart Association Class IV [NYHA, 1994], known left ventricular ejection fraction <30 percent) neurological, psychiatric, renal, hepatic, immunological, endocrine (including uncontrolled diabetes or thyroid disease), peptic ulcer disease, or hematological abnormalities. Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study. (Note: subjects 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).
