Clinical Research Studies

What Are Clinical Trials (Also known as Research Studies)?

Clinical trials are research studies conducted to gather information about whether a medical treatment, medication, or device is safe and effective for humans. Clinical trials produce needed data for health care decision making.  Clinical trials are one of the final stages of a long and careful research process.

Clinical trials of new medicines or medical devices are done in phases one through four.  Phase 1 clinical trials test new treatments on small groups of people for safety and side effects.  If results show promise, the treatment may proceed to phase 2 to look at how well the treatment works in a patient with the disease it is intended to treat and seeks to find the most effective and safest dose.  Phase III clinical trials use larger groups of people to confirm how well treatments work, further examine side effects, and compare new treatments with other available treatments.

All of these results are important because they advance medical knowledge and help improve patient care.

How Do Clinical Trials Work?

If you take part in a clinical trial, you may get tests or treatments in a hospital, clinic, or doctor’s office.  In some ways, taking part in a clinical trial is different from having regular care from your own doctor. For example, you may have more tests and medical exams than you would otherwise.

Each clinical trial has a master plan called a protocol (PRO-to-kol).  The protocol outlines what will be done during the clinical trial and why.  Each medical center that conducts the research study uses the same protocol.

The clinical trials are led by a principal investigator (PI). The principal investigators conducting trials with Western States Clinical Research, Inc. are all board certified medical doctors.  The protocol outlines what will be done during the clinical trial and why.  Each medical center that conducts the research study uses the same protocol.

Key information in a protocol includes:

  • who is eligible to take part in the clinical trial
  • what tests patients will get and how often they will get them
  •  information about the treatment plan

Eligibility Criteria A clinical trial’s protocol describes what types of patients are able to take part in the research—that is, who is eligible. Each trial must include only people who fit the patient traits for that study (the eligibility criteria).  Eligibility criteria differ from trial to trial. They include factors such as a patient’s age and gender, the type and stage of disease, and whether the patient has had certain treatments or has other health problems.
