Study to Evaluate the Safety and Efficacy of 13 Weeks of the Selective Androgen Receptor Modulator (SARM) GSK2881078 in Chronic Obstructive Pulmonary Disease (COPD)

Completed · Phase 2 · Has a placebo group

Conditions studied: Cachexia

In brief

Impaired physical function and muscle dysfunction are a major consequence of COPD, which may be associated with increased mortality, poor quality of life and increased health care use. This is a randomized, placebo-controlled, double-blind, parallel group study to evaluate the safety and tolerability of GSK2881078, an SARM over 13 weeks of dosing in older male subjects and post-menopausal female subjects with COPD and muscle weakness. This study will also assess the effect of GSK2881078 on physical strength and function after 13 weeks of treatment. Approximately 100 subjects with COPD and muscle weakness will be randomized into two cohorts of 50 male subjects and 50 female subjects. Within each cohort, subjects will be randomized to receive GSK2881078 or placebo in a ratio of 1:1. All subjects will participate in a standardized home exercise program, which will consist of daily walking, along with several resistance or weight-bearing exercises, such as bicep curls, upright rows, step ups and a sit-to-stand maneuver. The study will consist of a screening/Baseline period of up to 30 days, a 13-week treatment period and a post-treatment follow-up period of 6 weeks.

Age: 50 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject must be 50 to 75 years of age inclusive, at the time of signing the informed consent.
• Male and/or female subjects will be included. a) A male subject with a partner who is a woman of child bearing potential (WOCPB) must agree to use contraception during the treatment period and until at least 5 half-lives of study medication have passed after the last ingested dose [125 days, corresponding to time needed to eliminate study treatment for both genotoxic and teratogenic study treatments plus an additional 90 days (a spermatogenesis cycle) for study treatments with genotoxic potential] after the last dose of study treatment and refrain from donating sperm during this period. b) A female subject is eligible to participate if she is post-menopausal and not a WOCBP.
• Confirmed diagnosis of COPD in accordance with the American Thoracic Society (ATS)/European Respiratory Society (ERS) criteria with a post-bronchodilator FEV1/forced vital capacity (FVC) <0.70 and 30% <= FEV1% predicted <=65% of predicted normal value calculated at Screen using the Quanjer reference equation.
• SPPB with ALL of the following: Timed chair stand score >=1 and <=3; No score of "0" on any component of the SPPB (that is, gait speed, balance, or timed chair stand).
• Body Mass Index (BMI) within the range 18-32 kilogram per meter square (kg/m\^2) (inclusive), where BMI = (weight in kg)/(height in meters)\^2
• Current smokers or former smokers with a cigarette smoking history of >=10 pack years (1 pack year =20 cigarettes smoked per day for 1 year or equivalent). Former smokers are defined as those who have stopped smoking for at least 6 months prior to Baseline.
• Subjects must be able to read and write in the language used for the provided electronic diary and be able to operate an electronic device to a level that allows them to complete an electronic diary on a daily basis.
• Subjects participating in a structured exercise program must be willing to convert their current exercise program to the home exercise program used in this study.
• Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and protocol.

You may not qualify if…

• Subjects with a history of myocardial infarction, angina, congestive heart failure exacerbation, hospitalization for cardiac etiology, stroke or transient ischemic attack in the past 12 months.
• Neurologic, musculoskeletal, osteoarthritis, or any other condition that in the opinion of the investigator limits subject's ability to complete study physical assessments.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• Subjects with a history of cholecystectomy.
• Subjects with a history of malignancy that is not in complete remission for at least 2 years or 1 year for non-melanoma skin carcinoma.

• Diseases known to cause malabsorption of protein or energy, such as inflammatory bowel disease, celiac disease, pancreatic insufficiency, etc.
• Current or planned administration of cholestyramine or strong oral or injectable cytochrome P-450 isoenzyme 3A4 (CYP3A4) inducers.
• Current or planned use of any prescription drugs known to affect muscle mass, including androgen supplements, anti-androgens (such as luteinizing hormone-releasing hormone [LHRH] agonists), anti-estrogens (tamoxifen, etc.), recombinant growth hormone, megesterol, etc.
• Use of oral steroids concurrently or within 4 weeks preceding the screening visit.
• The subject has participated in a clinical trial and has received an investigational product within the following time-period prior to randomization in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
• Subjects with values outside the specified ranges for the following Key Clinical Laboratory Tests must be excluded from the study: a) Renal function: Glomerular Filtration Rate (GFR) <30 milliliter per minute per 1.73 meter square (mL/min/1.73 m\^2). Subjects receiving dialysis are excluded from this study. b) Metabolic-glycated hemoglobin (HbA1c) >7.5%. c) ALT >2 times upper limit of normal (ULN) and bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). d) Hematology - Hemoglobin <10.0 grams per deciliter (g/dL) at screening. e) Prostate Specific Antigen (PSA) >4.0 nanograms per milliliter (ng/mL).
