The General Clinical Research Unit (GCRU) at the Boston University Clinical & Translational Science Institute (CTSI) provides resources to faculty at the Boston University Medical Center, including a controlled and optimal setting for clinical investigators, career development programs, and training for health professionals. The GCRU is currently the setting for a large number of active protocols, it is also part of a national network of 62 academic medical institutions across the country that offer infrastructure and clinical investigation resources. Examples of resources provided by the GCRU include:

  • The ability to conduct pharmacokinetic studies in a controlled environment with both adult and pediatric inpatients and outpatients
  • Resources for timed collection of specimens and other specialized testing (bone density, CT scan etc.)
  • A private environment to explore patterns of behavior
  • A primary location for the education of future physicians, scientists and nutritionists in patient-oriented research

BU CTSI offers resources to investigators in medicine and dentistry funded by various sponsors including Federal, Non-Federal and Industry, as well as those conducting innovative clinical research pilot studies, prior to requesting funding. Experienced medical professionals help by facilitating the day-to-day research activities for physicians, trainees and subjects. The GCRU boasts a highly trained research staff of 8 who support inpatient and outpatient, adult and pediatric, medical and dental studies that discover the cause, progression, prevention, control and cure of human diseases. For specifics on services available, please contact the Nurse Manager Ridiane Denis RN at or call 617-414-1961.

Specialized Equipment        TOP

  • DEXA bone densitometer with fat distribution analysis
  • CT Scan
  • An exercise treadmill
  • A videotaping laboratory

Bone density facility:
A new bone density instrument the Hologic QDR 4500W was purchased in 2014. It is capable of doing bone densitometry, as well as fat distribution analysis in adults, children and infants. The QDR 4500W is a multiple detector, fan-beam Dual-energy X-ray Absorptiometry (DXA) bone densitometer. Hologic QDR 4500W Instruments allow regional and global measurements of the whole body. An advanced application of QDR technology can directly measure fat and skeletal mass and is useful in research and clinical studies.

Xtreme CT scans:
The SCANCO MEDICAL AG XtremeCT preform a quantitative computed tomography scan of the distal radius or distal tibia to provide measurements of volumetric bone density, which can be used as an aid to the physician in determining risk of fracture.

Treadmill - Pro-Form 505 CST (model no. PFTL60910.1)
This treadmill features a walking belt coated with high-performance lubricant. The console features 15 on board workouts as well as allowing manual operation. The treadmill’s speed and/or incline can be changed as desired. This particular model has an iFit feature that can be used if a subscription is purchased.

Observation and videotaping laboratories
Specialized areas are available for recording developmental behavior of children and adults.

General Clinical Research Unit (GCRU) Rates        TOP

Due to new regulations that do not allow CTSA funds to pay for staff working on research protocols, effective as of July 1, 2015 the GCRU is implementing a new fee structure. Services provided by the GCRU will no longer be subsidized by the CTSA grant and will need to be paid from relevant grants or contracts.
Separate rates have been established for Investigator-Initiated Protocols (NIH, DoD, private foundation, etc.) and for Industry-Sponsored Protocols. Please see below for a full list of rates.

Applications to use the GCRU indicates a commitment and agreement to financially support the fee for service policy

In the past, we have made individual exceptions exempting an investigator from GCRU charges for services, typically because the NIH or non-federal grant budget supporting the project was already in place and did not include funds for GCRU costs. Unfortunately, such exceptions will not be possible going forward as the new regulations prohibit the CTSI from subsidizing research activities with NIH CTSA funds. However, there might be the possibility of using CTSA funds to provide vouchers for GCRU services to unfunded junior investigators initiating pilot studies. Please contact the GCRU administration for more details or with questions.

Method of Payment
Following receipt of an approval letter for use of the unit, investigators will be asked to submit a completed GCRU Usage Billing Form, providing an account number which will be charged for services. An invoice for services will be sent monthly to the investigator with 5 business days for review. The account will, after 5 business days, be charged by internal journal entry. Fees will be reinvested in program resources to continue support of translational research.
