The Four Phases of Investigational Research Studies - Tri-State News, Weather & Sports

The Four Phases of Investigational Research Studies

A phase one, or early investigational study of a drug, is conducted with healthy people, to track how the body metabolizes and eliminates a drug. This phase of testing is limited to one or just a few sites worldwide and may involve from 20 to 100 subjects. Covance GFI Research Center is the only phase one research facility in the Tri-State.

Phase two, three and four studies may measure the safety, tolerability and effectiveness of a single drug or new combinations of drugs for treating diseases. Some studies may provide an investigational drug to people affected by an illness or condition. Covance GFI may be one of several sites worldwide testing drugs in these developmental stages.

Many types of drugs are researched, from simple aspirin-type drugs to new breakthroughs in diseases such as cancer and diabetes.

Volunteers are the critical link.

Covance GFI relies on volunteers to participate in clinical trials. Covance GFI physicians and medical staff carefully monitor each volunteer throughout the study. Representatives from pharmaceutical companies routinely visit our facility in Evansville, Indiana to review records and verify that Covance GFI procedures follow the study protocol.

Volunteers who stay in-house enjoy the comfort of semi-private rooms, each with a television and VCR. All food is provided...some is even catered by local restaurants! Recreational facilities include a pool table, big screen television and video and reading libraries. Quiet spaces are available for working on research papers and reading assignments.

All patients who qualify for a study are fully informed of the nature, risks and benefits of the study and what their participation will involve. A volunteer may discontinue study participation at any time.

Volunteers receive study-related medical exams and study drug, as well as compensation for time and travel.


What is the Two Step Program?

Volunteering to help to further medical science and improving medical care for future generations... that's the First Step.

The Second Step is contributing all or part of your volunteer stipend to a favorite charitable, religious or fraternal organization.

In addition, donations made to bona fide non-profit organizations may be tax-deductible.


Covance GFI Research Center is located on the campus of St. Mary's Medical Center. Dr. Randall Stoltz, Medical Director.
