Clinical Trials

IMPORTANT!
Clinical trials listed for ITP are a starting point for discussion with a health care professional. Be sure you understand all the implications of the proposed treatment and read the informed consent very carefully before enrolling in a clinical trial.

What are Clinical Trials?

Clinical Trials are controlled patient studies that must be performed before a new drug or treatment is approved by the Food and Drug Administration in the US and similar organizations in other countries.  Clinical trials are also done after a drug or treatment is approved to document the effectiveness of the treatment or to gain approval to use the drug or therapy for a different disease or age group.

There are three main phases to clinical trials, done in sequence.  A Phase I study tests the safety and side effects of the drug.  A Phase II study is initiated to determine the efficacy of the drug, to see if it works as anticipated.  A Phase III study tests the efficacy of drug or treatment and documents the side effects in a large population of volunteers.

Finding a Clinical Trial

The best way to find the latest information on clinical trials is to visit ClinicalTrials.gov.  Pharmaceutical companies and researchers update this site frequently so it contains the most comprehensive and up-to-date clinical trial listings.  It features an easy-to-use search facility and detailed guidance for patients and industry.
