Frequently Asked Questions

Our staff is happy to answer any questions you may have regarding the volunteer process at the ACPRU. Here are some common questions we receive.


General Questions

  • Clinical trials are research studies that explore whether a medical strategy, treatment or device is safe and effective for humans.

  • Phase I: Assessment of safety, tolerability, and dosing of the drug or treatment in humans (less than 100)
  • Phase II: Further evaluation of drug or treatment safety, efficacy and dosing in humans (100 - 500 people)
  • Phase III: Drug or treatment is given to a larger group of people to evaluate safety and efficacy (300 - 3000 people)
  • Phase IV: Post-marketing studies delineate additional information including drug or treatment risk, benefits, and optimal use (3000+ people)

  • The AbbVie Clinical Pharmacology Research Unit (ACPRU) conducts clinical testing of new and existing medications or medical devices.
  • The ACPRU supports AbbVie in determining the safety, tolerability, and dosage levels of medications and how the body absorbs and processes the medications.

  • Generally, healthy men and women between the ages of 18 to 55 are eligible to participate.
  • Occasionally, ACPRU conducts trials for:
    • Individuals aged 56 and greater.
    • Individuals with specific medical conditions.

  • You can check out the “Available Trials” page, or call us at 1-800-827-2778 for details.

  • You may stay overnight at the ACPRU for the duration of the study.
  • You will be dosed with the drug or treatment that is being studied.
  • You may have study procedures like vital signs, ECGs, or blood draws performed.
  • You will be asked to follow all instructions as given by the ACPRU staff.

  • These requirements vary by clinical trial. Please contact the ACPRU recruiting team at 1-800-827-2778 for details.

  • Informed consent is a process by which a volunteer decides if they want to participate in a study after being fully informed of any known risks.

  • Your participation in any study is entirely voluntary.  You may refuse to take part in screening, or you may stop participating at any time, even after signing an Informed Consent Form. This is your right.

  • You may be eligible to receive compensation for participation. Compensation varies by clinical trial based on the amount of your time that is required.  For more details, check the “Available Trials” page or call us at 1-800-827-2778.

  • Compensation may be given for referrals that result in a volunteer participating in a study.  Contact the ACPRU recruiting team at 1-800-827-2778 for details.

  • Clinical trials may:
    • Last a single day where you come and go the same day
    • Last several days or a few weeks, these studies generally require overnight stays
    • Include one or more outpatient visits after overnight stays are completed
    • Include one or more phone calls with the study nurse after the overnight stays have been completed
  • The ACPRU recruiting team can discuss with you how long a particular trial will last and what you will need to bring with you if you participate in a trial.  To learn more, call our team at 1-800-827-2778 for details.

  • We provide Wi-Fi, internet access, pool tables, library, TV room, and a gaming and multimedia room for study participant use.

  • Visitors may be allowed between 1:30 p.m. and 6:00 p.m. Monday through Friday, providing they do not interfere with scheduled study activities, and are restricted to the visitors’ area.


Screening Questions

  • Screening procedures are conducted to find out if a volunteer is eligible to participate in ACPRU clinical research trials.

  • The screening process consists of a telephone screen which can take approximately 20 minutes, and an onsite health screen which can take up to 3 hours. Health screening is also available on select weekends at two remote locations, in Chicago and Rockford. See the “Directions” page for more information.

  • BMI, or Body Mass Index, is a person's weight divided by the square of their height. It does not measure body fat directly. The BMI is obtained as part of the general health screening to ensure a volunteer is eligible to participate in a clinical trial (Centers for Disease Control and Prevention).
