Study Phase
Click the check box to the left of each study phase that you wish to include in your search. You can select more than one study phase. If you do not select a any phase, all phases will be included.
Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions
that study is seeking to answer:
In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.
These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.

There are three types of studies available in ClinicalTrials.gov:
Interventional:
Observational:
Expanded Access:
Studies where individuals are assigned to receive specific interventions.
Participants may receive diagnostic, therapeutic or other types of interventions.
Assignment of the intervention may or may not be random.
Individuals are tracked and biomedical and/or health outcomes are assessed.
Observational:
Studies without an intervention.
Studies where biomedical and/or health outcomes are assessed in a pre-defined group of individuals.
Participants may receive diagnostic, therapeutic, or other interventions, but the investigator
does not assign specific interventions to the participants of the study.
Expanded Access:
Records describing the procedure for obtaining an experimental drug or device for patients who
are failing on currently available treatments for their condition and also are unable to
participate in ongoing clinical trials. Expanded Access records are used to register all
types of non-protocol access to experimental treatments, including protocol exception,
single-patient IND, treatment IND, compassionate use, emergency use, continued access and parallel track.
Study Results
Searches can be restricted to studies with or without results.
The inclusion of study results is a relatively new feature of ClinicalTrials.gov. Collection of results began in September of 2008. Almost all older studies and some newer studies do not include results. As time goes on, there will be more results available.

Recruitment Status
Also known as Enrollment Status.
Not all clinical trials in this database are accepting new participants. If you are looking for studies that are currently recruiting participants, will be recruiting in the future, or are about drugs that are available for expanded access, select Open Studies in the recruitment menu.
If you are interested in all trials, whether they are recruiting new participants or not, leave the menu with All Studies selected.
Trials may not be recruiting because they are full, completed, or halted for various reasons. In addition, some trials have very restrictive eligibility requirements and must seek participants by invitation only. To see these studies, Select Closed Studies in the recruitment menu.

Help for Searching clinical trials
Help Topics:
Basic Search:
On the Basic Search page, enter a word or word(s) that you want to use to find studies.
These may include diseases, interventions, and/or locations.
Medical terms are often several words long, such as Percutaneous Coronary Intervention. To only find studies where the words are together as a phrase, put the term in quotes (e.g., "Percutaneous Coronary Intervention"). If you search for a multi-word term without quotes, studies with all words together as a phrase will appear higher in the results list than studies where the words are separated and spread throughout the document. For example, a search for Heart Attack will list a study about,
A search for "Heart Attack" would not find the second study. Synonyms are known for some terms and are used where possible. For example, a search for Heart Attack will also find occurrences of Myocardial Infarction.

Advanced Search:
Many searches are a single term and can be performed with a few words in the
search box. But, sometimes you need more control. Click on the Advanced Search tab
(if starting a new search) or Refine Search tab (if modifying an existing search)
to show additional search fields.
The additional search fields can be used to limit your search results. Note that it is not necessary to fill in all the fields, only those that are needed for your search. If you are finding too few studies, consider clearing a field and searching again.

Sponsor/Collaborators:
Performs a search on fields listing the sponsor and collaborators of a study.
When the Exact Match checkbox is checked, the sponsor/collaborator name in the study must exactly match the name in the search. For example, if unchecked, a search for Merck in the sponsor/collaborator field will find Merck, Merck KGaA, Dupont Merck, and Merck Sharp & Dohme. When checked, only Merck, with no other words in the name, will be found.

Study IDs:
Performs a search on fields listing ID numbers.
Country/State:
Trials are often conducted at many locations around the world.
Select up to three locations to find trials conducted in
specific countries. Some countries (currently limited to the
United States, Canada, and Australia), locations can be narrowed
further by selecting a state (e.g., United States, Alabama).
Location Terms:
Finds studies in specific locations such as a city (Los Angeles) or facility (Mayo Clinic).
Not all studies include this level of detail, but if they do, this will find them.
Gender:
Limits search results to those studies that accept female or male participants.
Age Group:
Limits search results to those studies that include at least one of the specified age
ranges. More than one age group can be selected.
Phase:
Limits search results to studies that are labeled with at least one of the specified
phases. More than one Phase can be selected.
Funded By:
Limits search results to studies that have at least one sponsor of the specified types.
More than one sponsor type can be selected.
Safety Issue:
Limits search results to studies that have at least one outcome measure designated as a safety issue.
First Received:
Limits search results to studies that were received by clinical trials within a
specified date range. The "From" or "To" field can be left blank.
Last Updated:
Limits search results to studies that were modified within a
specified date range. The "From" or "To" field can be left blank.
Refine Search:
Searches display a list of studies found (List Results tab). If you are not content with
the search results, click on the Refine Search tab at the top of the list to modify your
search.
Add terms to empty fields to search within your current result. You can also add terms to fields that contain terms. For best results, use an AND (all upper case) as a separator between terms in the same field.

Search Expressions:
Use AND (all upper case) to find study records that contain all terms connected by AND.
For example:
Use OR (all upper case) to find study records that contain either term connected by OR.
For example:
Use NOT (all upper case) to find study records that do not contain the term following NOT.
For example:
Likewise, AND, OR, NOT, and parentheses can be used to create more complicated search expressions.
For example:
Note that the use of AND and OR as logical operators can be confusing.
An appropriate search for a list such as,
To search for AND as a word, instead of using it as an operator, put it in quotes.
Likewise, you can quote OR, NOT, and parentheses.
For example:
prostate cancer AND radiation
heart disease AND stroke AND California
heart disease AND stroke AND California
Use OR (all upper case) to find study records that contain either term connected by OR.
For example:
Aspirin OR ibuprofen
heart disease OR heart attack
heart disease OR heart attack
Use NOT (all upper case) to find study records that do not contain the term following NOT.
For example:
Immunodeficiency NOT AIDS
Likewise, AND, OR, NOT, and parentheses can be used to create more complicated search expressions.
For example:
prostate cancer AND NOT ( radiation OR homeopathic remedies )
( heart disease OR heart attack ) AND ( stroke OR clot )
( heart disease OR heart attack ) AND ( stroke OR clot )
Note that the use of AND and OR as logical operators can be confusing.
An appropriate search for a list such as,
Ear, Nose, and Throat Conditions
is the expression
( Ear OR Nose OR Throat ) AND Conditions
Fortunately, search will do a pretty good job of finding the right studies either way.To search for AND as a word, instead of using it as an operator, put it in quotes.
Likewise, you can quote OR, NOT, and parentheses.
