Randomized, Controlled Trial of Extended-Release Niacin (Niaspan®) to Augment Subacute Ischemic Stroke Recovery
Randomized, Controlled Trial of Extended-Release Niacin (Niaspan®) to Augment Subacute Ischemic Stroke Recovery
The purpose of this study is to determine the safety, tolerability, and to explore the
 possible benefit of extended-release niacin (Niaspan®) in attempting to improve the recovery
 of patients after ischemic stroke.
The investigators are interested in extended-release niacin (Niaspan®) and its potential
 restorative role after ischemic stroke. At Henry Ford Hospital in Detroit, Michigan,
 extended-release niacin (Niaspan®) has been shown to improve the functional outcomes of rats
 when administered during the first two weeks after ischemic stroke onset. Such results are
 encouraging and warrant further investigation in humans. The specific aims of this study are
 to prospectively evaluate the use of extended-release niacin (Niaspan®) in a phase II
 clinical trial in patients with subacute ischemic stroke. The investigators will assess the
 safety and tolerability of Niaspan® and evaluate outcomes among treated patients at 24 weeks
 after ischemic stroke onset. This will be a randomized, double-blinded, placebo-controlled,
 safety, tolerability, and exploratory efficacy study of extended-release niacin (Niaspan®) in
 subacute ischemic stroke patients with both low HDL-C and normal HDL-C in cohort sizes of 16
 patients. A total enrollment of 48 patients is planned. Patients who are between 72 hours and
 7 days from stroke onset will receive Niaspan® 500mg, 1000mg, or placebo daily for a period
 of 24 weeks. Evaluation of potential safety and tolerability in subacute ischemic stroke
 patients will be made during the course of treatment and at formal visits at 6, 12, and 24
 weeks. The primary safety measures will be death, recurrent stroke, myocardial infarction,
 and neurological worsening during treatment. Exploratory analysis will include functional
 outcomes on the NIHSS scores, modified Rankin scores, and Barthel indices at 24 weeks. The
 goal of this study is to improve the outcomes from ischemic stroke, using a safe and
 effective novel strategy of restoration, which has been translated from basic laboratory
 studies.
Inclusion Criteria:

 -  Patients with clinical ischemic stroke able to enroll between 72 hours and 7 days
 after symptom onset.

 -  Patients age 18-85, inclusive.

 -  NIHSS score of 4-21, inclusive, prior to treatment.

 -  Signed IRB-approved informed consent by patient or authorized representative.

 Exclusion Criteria:

 General

 -  Participation in another study with an investigational drug or device.
