Summary
This study will test the safety and effectiveness of a protein called E-selectin, given as a
nasal spray, in preventing the formation of blood clots that can cause stroke. In animal
studies, animals that received E-selectin in the nose on a regular schedule had almost no
strokes compared with those that did not receive it.
Patients over age 45 who have had a stroke or transient ischemic attack (TIA) within 1 to 4
months of this study may be eligible to participate. Candidates will be screened with a
review of their past medical records and neurologic and medical evaluations that may include
magnetic resonance imaging (MRI) of the brain, ultrasound or magnetic resonance angiography
(a type of MRI) of the carotid arteries (arteries in the neck that supply blood to the
brain), echocardiography (ultrasound test of the heart), electrocardiography (EKG) and blood
tests.
Participants will have a blood and urine test and will be assigned to one of four treatment
groups. Patients in each group will spray a small amount of fluid into their nose according
to the following schedule: 5 doses once every other day for 10-days, followed in 3 weeks by
another 5 doses every other day for 10-days, followed in 3 weeks by a final series of 5 doses
every other day for 10 days. The spray for patients in each group contains the following:
- Group 1 - fluid with low dose of E-selectin
- Group 2 - fluid with medium dose of E-selectin
- Group 3 - fluid with high dose of E-selectin
- Group 4 - fluid with no E-selectin
Patients will be seen for follow-up visits at 1 month and 3 months after starting E-selectin
therapy. The visits will include a neurologic examination and blood and urine tests. Patients
will be contacted by phone, fax or e-mail in between the 1- and 3-month visits.
