Clinical drug trials are research studies conducted in patient populations to evaluate the safety and effectiveness of investigational medications and/or uses for existing medications.


A participant is given an Informed Consent Agreement, which provides a detailed explanation of the nature and the purpose of the study.  A copy of the Experimental Subject’s Bill of Rights is also provided.  Studies may last from a few weeks to several months.  Study participants are evaluated and monitored by our physicians and clinical staff at frequent intervals.  Physical examinations and laboratory tests may be required periodically throughout the study period.  All study-related visits and/or procedures are entirely cost-free.  In fact, some studies even provide funds for travel and related expenses.


Services usually include laboratory tests, electrocardiograms (EKG’s), physical examinations, and visits with one of our study physicians at no cost to you.  Other benefits include the health information derived from laboratory results and the evaluation of your general physical and mental health.  If needed, you will receive referrals for additional treatment.


Your medical records are confidential.  The patient’s name is removed from the study results.  Participants are identified by a numerical coding system.  The drug company of the FDA may access medical records, in order to verify data collected.  Only at your request and only with your permission, your personal physician can be contacted about your participation in the study, and a summary of findings will be provided for your continuing care.
