How to Find Clinical Trials Using the Search Form

 

The clinical trials search form allows you to search for trials using one or more criteria. Not all of the criteria are visible in the default display of the form. Some of the criteria are organized in groups, for example, Trial/Treatment Type includes Trial Type, Drug, and Treatment/Interventions. You can click on "Show Search Options" to see all of the options within a group.

Default search view Default search view.



Expanded search option view Expanded search option view.

Each option on the form is described in the following sections with tips to make your search more effective. You can skip any options that you don't know or that don't apply to your situation.

 
 

Cancer Type/Condition

Use this list to choose the type of cancer being studied in a clinical trial(s), e.g., bladder cancer, prostate cancer. You also have the option of choosing "All."

  • If you want trials for any type of solid tumor, select "Solid tumor, unspecified."
  • For trials that treat metastatic cancer, select "Metastatic cancer."
  • You can also search for trials on cancer-related conditions by choosing either the specific condition (e.g., fatigue) or "Cancer- and cancer treatment-related conditions."

    Stage/Subtype

    After you choose a type of cancer, this list will show you the stages/subtypes for the selected cancer. The stage of cancer is the extent of cancer within the body. You may select one or more stages/subtypes or "All."

    • If you want a definition of the stage/subtype of cancer, please check the NCI Dictionary of Cancer Terms.
    • If you choose "Cancer- and cancer treatment-related conditions" from the Cancer Type/Condition list, the Stage/Subtype box will show you a list of conditions that may result from having cancer or being treated for cancer.

Trial Status/Phase

Use these options to search for trials by the status (active or closed) or by the phase of the trial, and to search for trials that were added within the last 30 days.

Trial Status

Use this option to choose whether to search for active trials (accepting new patients) or closed trials (no longer accepting new patients).

  • The default is for active trials.
  • Closed trials may have published information describing what researchers have already studied and learned.
  • Closed trials are not searchable by location.
 

Trial Phase

  • Phase I - trials that test the best way to give a new treatment (for example, by mouth, intravenous infusion, or injection) and the best dose.
  • Phase II - trials that test whether a new treatment has an anticancer effect (for example, whether it shrinks a tumor or improves blood test results) and whether it works against certain types of cancer.
  • Phase III - trials that compare the results of people taking a new treatment with the results of people taking the standard treatment (for example, which groups have better survival rates or fewer side effects).
  • Phase IV - trials that evaluate side effects that were not apparent in the phase III trial.
  • Phase may not be applicable to all trials, e.g., Natural history/Epidemiology trials.

New Trials

Cooperative Group sites located within the United States and Canada are currently eligible for participation in the CTSU. In addition, the CTSU is open to physicians and institutions in the United States who are not affiliated with a Cooperative Group.
  • Group C-Treatment IND trials - These trials use Group C-designated drugs, investigational drugs found to have anti-tumor activity which are awaiting final FDA approval and are not yet available on the market.
  • NCI-CMS pilot project trials - These trials were selected for a pilot project between the National Cancer Institute (NCI) and the Center for Medicare and Medicaid Services (CMS). Under this pilot project, the CMS will cover the routine and non-routine costs for these trials.
  • NCI Avon award trials - Breast cancer trials funded by the NCI-Avon Progress of Patients Awards program, a partnership between NCI and the Avon Foundation, the charitable arm of Avon Products, Inc.
  • NCI Cancer Bulletin featured trials - NCI-sponsored trials that were highlighted in a Cancer Bulletin article to give them added attention.
  • NIH Clinical Center trials - Trials being conducted at the NIH Clinical Center in Bethesda, Md.
  • SPORE trials - Trials funded through NCI's Specialized Programs Of Research Excellence (SPOREs). The goal of the SPORE program is to bring to clinical care settings novel ideas that have the potential to reduce cancer incidence and mortality, improve survival, and improve the quality of life. Laboratory and clinical scientists work collaboratively to plan, design, and implement research programs that impact on cancer prevention, detection, diagnosis, treatment, and control.
  • Treatment Referral Center (TRC) trials - These trials offer investigational treatments for certain high priority agents or diseases and are available only at NCI-designated cancer centers.
