Clinical Trials Information for Patients and Caregivers

This National Cancer Institute (NCI) webpage includes basic information about clinical trials to help you understand what’s involved in taking part.

What are clinical trials?

Clinical trials are research studies that involve people. They are the final step in a long process that begins with research in a lab. Most treatments we use today are the results of past clinical trials. Cancer clinical trials are designed to test new ways to:

  • Treat cancer

  • Find and diagnose cancer

  • Prevent cancer

  • Manage symptoms of cancer or side effects from its treatment


PRE-ACT (Preparatory Education About Clinical Trials) is an educational program designed to provide general information about clinical trials.

Where can I find cancer clinical trials in my community? currently lists over 300,000 studies with locations in all 50 States and in 191 countries.

The Northwell Health Cancer Institute has over 30 years of experience offering clinical trials to patients in our community. Driven by our tranformative collaboration with Cold Spring Harbor Laboratory and our participation in the National Cancer Institute Community Oncology Research Program, at any given time, there are more than 125 cancer research studies being conducted. 


The American Cancer Society Clinical Trials Matching Service is a free, confidential program that helps patients, their families and health care workers find cancer clinical trials most appropriate to a patient's medical and personal situation.

Work one-on-one with an LLS Clinical Trial Nurse Navigator who will help you find clinical trials and personally assist you throughout the entire clinical-trial process.
