Clinical Trials

A clinical trial is a method for medical researchers to study, test and discover effective treatments. Clinical trial research studies can occur in a lab or involve human beings.

The SQUID Trial for the Embolization of the Middle Meningeal Artery (STEM) for Treatment of Chronic Subdural Hematoma (IRB00253687)

Principle Investigator: Justin Caplan, M.D.
Contact: Whitney Isennock (wwebb10@jhmi.edu, 667-306-8145)
Summary: To test the safety and efficacy (how well it works) of embolization to treat MMA bleeds using SQUID™ in surgically treated and non-surgically treated patients with cSDH.
Eligibility Criteria: People who have been diagnosed with chronic bleeding between the hard-cerebral membrane and the brain, also known as chronic subdural hematoma (“cSDH”) may join this study.

OPTIMIST: Optimal Post Tpa-IV Monitoring in Ischemic Stroke

Principle Investigator: Victor Urrutia, M.D.
Summary: To show safety of post-tPA monitoring in a non-ICU setting for patients presenting with minor stroke symptoms (NIHSS<10)
Major inclusion criteria:

  • Patients receiving IV tPA for presumed stroke within 4.5 hours of symptom onset
  • NIHSS <10 at presentation and at the end of tPA infusion
  • Age 18-80 years
  • Patients do not have ICU needs by the end of the tPA infusion

Major exclusion criteria:

  • Age <17 or >80
  • ICU need or indication by the end of the tPA infusion
  • NIHSS >9 at presentation or at the end of the tPA infusion

Proceedings:
At the end of the one-hour tPA infusion, eligible patients will be consented for this study and will continue with neurocheck and vital signs Q 15 minutes x 4 in the ED. The patient may transfer to the BRU after the third Q 15 minute interval, so that they receive the 4th in the BRU. After arrival to the BRU, they will receive a set of vital signs and neurochecks upon arrival and at one hour, then Q 2 hours for 8 hours and then Q 4 hours until completing the 24 hour post tPA.
