GSK1278863 Effects on Eccentric Exercise-Induced Muscle Damage

Completed · Phase 1 · Has a placebo group

Conditions studied: Tendon Injuries

In brief

As per non-clinical studies, prolyl hydroxylase inhibitor GSK1278863 can protect muscle from unaccustomed exercise induced muscle damage and enhance functional muscle repair. This study is designed to investigate arm function, pain and other pharmacodynamic (PD) markers after unaccustomed maximal eccentric exercise with concurrent administration of GSK1278863 or placebo. Primary objective of the study is to evaluate the protective effects of GSK1278863 on eccentric exercise induced muscle injury. Subjects will be randomized in a 1:1 ratio (1 subject on GSK1278863 for every 1 subject on placebo). Each subject will be given five oral doses of GSK1278863/placebo in total. The first dose will be administered immediately after completion of eccentric exercise and then 4, 8, 24, and 48 hours later. Subjects will be housed till day 4 in unit and will return for a follow-up visit 7-10 days after discharge. After enrolment of approximately 30 subjects, enrolment will be paused and planned interim analysis will be performed to decide whether to terminate enrolment/study, continue dosing or to reduce the dose to 5 milligrams (mg).

Who can join

Age: 18 and older, up to 35. Sex: male. Healthy volunteers: accepted.

You may qualify if…

• A subject will be eligible for inclusion in this study only if all of the following criteria apply:
• Males between 18 and 35 years of age inclusive, at the time of signing the informed consent.
• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator in consultation with the GSK Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Subjects with hemoglobin values outside the normal range should always be excluded from enrolment.
• Body weight >= 70 kilogram (kg) and Body mass index (BMI) within the range 22.0 to 34.0 (inclusive).
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
• Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin <= 1.5x Upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Corrected QT interval (QTc) < 450 milliseconds (msec) based on single or average QTc value of triplicate values obtained over a brief recording period. The QT correction formula (Fridericia's) used to determine inclusion and discontinuation should be the same throughout the study.
• At least a 1year history of no regular (2-3 times per week) exercise and no heavy exertion within past week, and in the examining physician's opinion the study participant's physical condition/physique is consistent with a history of no regular physical activity for the past year.
• No strenuous exercise involving the arms during the last 10 weeks (e.g., resistance training, rock climbing, rowing, chopping wood, digging, shovelling, sawing).
• The subject is mentally and legally able to comply with the requirements and restrictions of the protocol and has provided signed informed consent prior to participation in any protocol-specific procedures, including Screening procedures.

You may not qualify if…

• A subject will not be eligible for inclusion in this study if any of the following criteria apply:
• Criteria Based Upon Medical History
• History of dizziness or vertigo.
• Uncontrolled hypertension [diastolic blood pressure (BP) >100 millimeter of mercury (mmHg) or systolic BP >170mmHg] at Screening.
• Taking anti-inflammatory, glucocorticoid or other pain medication more than 2 times per week over the previous month.
• Unwilling to abstain from taking prescription or non-prescription drugs (including vitamins and dietary or herbal supplements), within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication until completion of the follow-up visit, unless in the opinion of the Investigator and sponsor the medication will not interfere with the study.
• History of regular alcohol consumption within 6 months of the study defined as:
• An average weekly intake of >14 drinks for males. One drink is equivalent to 12 grams(g) of alcohol: 12 ounces [360 milliliter (mL)] of beer, 5 ounces (150mL) of wine or 1.5 ounces (45mL) of 80 proof distilled spirits.
• History of drug abuse or dependence within 6 months of the study.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the Investigator or GSK Medical Monitor, contraindicates their participation.
• History of peptic ulcer disease or upper gastrointestinal (GI) bleeding within the past 6 months.
• History of thrombosis defined as deep vein thrombosis, stroke, pulmonary embolism or other thrombosis related condition within 3 months prior to Screening.
• History of myocardial infarction or acute coronary syndrome within 3 months prior to Screening.
• History of stroke or transient ischemic attack within 3 months prior to Screening.
• Subjects with a pre-existing condition interfering with normal gastrointestinal anatomy or motility, and/or hepatic function that could interfere with the absorption, metabolism, and/or excretion of GSK1278863. Examples of conditions that could interfere with normal gastrointestinal anatomy or motility include gastrointestinal bypass surgery, partial or total gastrectomy, small bowel resection, vagotomy, malabsorption, Crohn's disease, ulcerative colitis, or celiac sprue. Examples of conditions that could interfere with hepatic function include Gilbert's syndrome.
• Evidence of active peptic, duodenal or esophageal ulcer disease at Screening OR history of clinically significant GI bleeding within 3 months prior to Screening.
• Subjects with chronic inflammatory disease that could impact erythropoiesis (e.g., scleroderma, systemic lupus erythematosis, rheumatoid arthritis, celiac disease).
• Subjects with a history of symptomatic right heart failure.
• Subjects with Class III or Class IV heart failure, as defined by the New York Heart Association (NYHA) functional classification system.
• History of proliferative vascular eye disease (e.g., choroidal or retinal disease, such as neovascular age-related macular degeneration, proliferative diabetic retinopathy or macular edema) based upon having had an ophthalmologic exam within 12 months prior to Screening.
• History of risk factors for hypercoagulable state:
• Factor V Leiden (the most common)
• Prothrombin gene mutation
• Deficiencies of natural proteins that prevent clotting (such as antithrombin III, protein C and protein S)
