3 Month PHI PAD PoM Study

Completed · Phase 2 · Has a placebo group

Conditions studied: Vascular Disease, Peripheral

In brief

This is a multi-center, randomized, blinded, placebo controlled study to evaluate the safety of GSK1278863 and its acute and short-term (e.g. 14d) effects on calf muscle endurance and walking ability in subjects with PAD and symptomatic claudication.

Who can join

Age: 40 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects ≥ 40 years of age.
• Male subjects must use one of the contraceptive methods listed in Section 8.1 for 90 days post-last dose.
• Females must be postmenopausal, surgically sterilized, or practicing a suitable method of birth control so that in the opinion of the investigator they will not become pregnant during the course of the study.
• A female subject is eligible to participate if she is of child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until 30 days post-last dose.
• Peripheral artery disease defined as an ankle-brachial index (ABI) at rest ≤ 0.90 in at least one leg in which the patient experiences claudication. For all subsequent evaluations, the Index Leg refers to the symptomatic leg with the lowest ABI.
• Claudication symptoms with stable severity for at least 3 months prior to screening.
• The patient is able to provide written informed consent to participate in this study.
• AST and ALT < 2xULN; alkaline phosphatase and bilirubin greater than or equal too 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Confirmed QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with bundle branch block.
• Subjects must be able to perform performance/exercise testing

You may not qualify if…

• Coronary artery bypass graft (CABG), open peripheral vascular procedures, or major surgical procedures within 6 months prior to screening or patients likely to require revascularization during the course of the trial. Endovascular procedures within 3 months prior to screening.
• Any unstable vascular syndromes (such as TIA, CVA, unstable angina or acute MI), including major changes to related medications, within 6 months prior to randomization.
• Critical leg ischemia classified as Fontaine Stage III-IV (rest pain, tissue necrosis or gangrene).
• Pregnant or nursing women (women capable of childbearing must have a negative pregnancy test).
• A hemoglobin value at screening is:
• Male subjects or post-menopausal females: > 15.5 g/dL Female subjects: > 14.5 g/dL
• Active malignancy or diagnosis of malignancy within 5 years prior to screening (excluding successfully treated basal or squamous cell carcinoma).
• Other clinically significant cardiovascular, pulmonary, renal, endocrine, hepatic, neurological, psychiatric, immunological, gastrointestinal, hematological, or metabolic disease that is, in the opinion of the Investigator or the Medical Monitor, not stabilized or may otherwise confound the results of the study.
• Patients with a baseline medical history of proliferative diabetic retinopathy, preproliferative diabetic retinopathy, or wet age-related macular degeneration (AMD)
• Previously enrolled in a gene therapy clinical study unless patient was randomized to placebo.
• Plans to initiate a formal exercise training program during the course of the study, or initiation of a formal exercise training program within 3 months prior to screening.
• Poorly controlled hypertension (defined as seated resting BP >160 mmHg systolic or > 95 mmHg diastolic, or both).
• Hypotension (defined as seated resting BP < 95 mmHg systolic or < 55 mmHg diastolic, or both, or symptomatic hypotension [seated, supine, or orthostatic]).
• Exercise tolerance, including bilateral heel raise and Six-Minute Walk Test performance, that is limited by co-morbid conditions or diseases other than claudication.
• Poorly controlled diabetes defined as Hemoglobin A1c (HbA1c) > 10%.
• Creatinine > 2.5 mg/dL or undergoing hemodialysis.
• Thrombocytopenia defined as platelet count < 100,000/mm3 at screening.
• Hematocrit ≤ 30% or ≥ 55%.
• International Normalized Ratio (INR) > 1.5.
• A positive Hepatitis B surface antigen or positive Hepatitis C antibody result if performed within 3 months of screening (testing not required at Screening).
• History of alcohol or drug abuse, or a significant medical or psychiatric disorder that may impair compliance with the requirements of the protocol.
• The patient has received an investigational drug within 30 days prior to this study.
• The patient is enrolled or plans to enroll in another clinical trial during this study
• History of venous thrombosis, defined as deep vein thrombosis, pulmonary embolism or other venous thrombotic condition, within 1 year prior to Screening.
• Acute peptic ulcer disease or history of chronic rectal bleeding.
