A Dedication to Dan Hanley and the CLEAR and MISTIE Project Teams

Composed and sung in Waikiki on 05-February-2013 by Keith Gregson while attending the International Stroke Conference. It is set to an old cajun fiddle tune and dedicated to Dan Hanley and members of the CLEAR and MISTIE teams at JHU, Baltimore, Maryland. Keith is the spouse of Barbara Gregson, who manages the STICH-II trial and is a member of the CLEAR steering committee.

Clinical Trial Participation and Placebo: The Unsung Heroes During Consent Discussions

From the perspective of a patient or a patient’s family during the time of a medical crisis the idea of consenting to an investigational trial can be very stressful. Most will focus on the risks of the investigational therapy and will find it difficult to realize the inherent benefits of participating in a clinical trial and the possible benefits of receiving a placebo. Historically the mortality rate of a patient suffering an intraventricular hemorrhage can be as high as 80% per the literature. In comparison, a review of the IVH thrombolysis safety (Safety) trial unblinded data shows that participation in a clinical trial reduced mortality to about 20% in both treatment groups. Although the treatment assignments remain blinded, this appears to be holding true for the current CLEAR III trial as well with 30-day mortality below 40% in both treatment groups. An assessment of A/B mortality is done by a blinded statistician at the time of each death to ensure that survival is occurring at the expected rate in both groups. This trend of survival in subjects enrolled in the trials is attributed to the stringent stability protocols required by the protocol which include optimal catheter placement, daily CT scans to monitor for bleeding, and strict blood pressure and intracranial pressure management.

CLEAR-III DSMB compliments study team

The Data Safety Monitoring Board (DSMB) for the CLEAR-III clinical trial met today to review detailed data on the first 175 patients in the trial (152 post Day-180), with additional preliminary data from a total of 251 enrolled patients from across 61 clinical sites. CLEAR-III is a phase III clinical efficacy and outcomes study assessing the effect of external ventricular drainage (EVD) with rt-PA or placebo to treat intraventricular hemorrhage (IVH). The first subject, out of a planned 500, was enrolled in September 2009.

CLEAR-III Coordinator of the Year

Coordinators of the Year 2012 attending the ISC Meeting in Honolulu next FebruaryEach July the BIOS coordinating center hosts an annual awards meeting where we honor those coordinators that have made exceptional contributions to this clinical trial over the last fiscal year. One of the most anticipated events during this meeting is the CLEAR-III Coordinator of the Year announcement. In keeping with our ThrombOlympics theme this month, we renamed the award as the gold medal and played the Olympic theme in the background, adding to the excitement. In very close competition, we had a tie and two coordinators won the gold medal this year:  Terry Cole from Rush University and Julie Martinez from the University of Utah.
