General Information

The National Center for Biomedical Ontology will host a two-day workshop focused on the Ontology of Clinical Trials. The workshop will take place on May 16-17, 2007 at the NIH Campus in Bethesda, MD.

The meeting will be divided into two parts. Day 1 will be a public event consisting of presentations and panel discussions on the CTO and cognate initiatives. Day 2 will be a working meeting devoted to intense discussions of mature drafts of the CTO and to the creation of a strategy for its further development and testing.

The work of the NCBO is funded by the National Institutes of Health through the NIH Roadmap for Medical Research, Grant 1 U 54 HG004028. Information on the National Centers for Biomedical Computing can be found here.

We are grateful to the National Heart, Lung and Blood Institute for generous support for this meeting.

Aim of the Workshop

The aim of the workshop is to foster the creation and dissemination of a reference ontology (high-quality controlled structured vocabulary) for the annotation of the results of clinical trials.

The Workshop will bring together representatives of all of the major groups involved in clinical trial informatics, design, execution, analysis and standardization, with the goal of achieving a broad consensus on the requirements which the ontology should address and on the most effective means of realizing these requirements. It will address the potential uses of CTO, and methodology for CTO design and development.

Goals of the Clinical Trial Ontology Initiative

The proposed CTO should:

(1) fully and faithfully capture the types of entities and relationships involved in clinical trials of any experimental design

(2) comprehend terms like: cohort, randomization, placebo, response, efficacy, control, protocol, null hypothesis, confidence interval, finding, biomarker, primary outcome, secondary outcome, intervention group, confounder, etc., including also major relevant statistical terms and terms drawn from resources such as the CDISC glossary and all terms needed for the task of meta-analysis of clinical trials;

(3) organize these terms in a structured way, providing definitions and logical relations designed to enhance retrieval of, reasoning with, and integration of the data annotated in its terms.

(4) support trial bank interoperation

(5) form an integral part of the more comprehensive framework of the Ontology for Biomedical Investigations OBI, which itself forms part of the OBO Foundry

(6) draw on and seek maximal alignment with existing clinical trial ontologies, including:

-- the Epoch ontology used by the Immune Tolerance Network

-- the RCT Schema ontology used by theTrial Bank Initiative

(7) rest on a clear understanding of the relation between CTO and related ventures such as an epidemiology study ontology

(8) rest on a clear understanding of the relation between CTO and data-model-oriented initiatives such as CDISC and BRIDG

(9) be created through an open process, in which all interested parties can be involved.

NIH Security Regulations

All visitor vehicles, including taxicabs, hotel and airport shuttles, delivery trucks and vans will be inspected before being allowed on campus. Visitors will be asked to show a form of government-issued photo identification (driver's license, passport, green card, etc.) and to state the purpose of their visit. Be sure to allow extra time for this vehicle inspection procedure. Employees and visitors should continue to wear their identification prominently at all times while on campus.

Guards will remain at certain buildings to address specific program requirements such as sensitive research and safety concerns. At building entrances where guards are posted:

• Visitors may be required to log in, wear a visitors pass and have an employee escort them through the building.
• Visitors may be required to pass through a metal detector and have bags, backpacks or purses inspected or x-rayed as they enter buildings.

Security staff will be looking for and confiscating any suspicious or potentially dangerous materials. U.S. Code prohibits bringing any dangerous weapons onto Federal property, including anything with a blade longer than 2½ inches. Meeting participants may want to leave extra bags or personal materials at their hotel to minimize the time needed for inspection.

All visitors including patients, contractors, vendors and delivery persons must use the following entrances:

Rockville Pike at South Drive (Metro):

• Open 24 hours - Inbound and Outbound traffic
• Open to All Vehicles
• Pedestrian Turnstiles Open for Employees
• Gateway Center at Metro Open for Visitor Registration--this is where visitors check-in with security if they are not driving

Old Georgetown Road at Center Drive (This entrance is primarily for commercial vehicles and visitors):

• 6am- 7pm -Inbound and Outbound Traffic
• Open to Employee, Commercial and Visitor Vehicles
• Pedestrian Turnstiles Open for Employees

Please note: Visitor parking is limited at NIH. Visitors are encouraged to use public transportation such as the Metrorail subway system which has a convenient stop (Medical Center) on the NIH campus.

Visitors arriving by bus will be dropped off at the NIH/Medical Center Metro stop at Rockville Pike and South Drive. Patients and visitors on official business can then ride the Campus Shuttle to the Clinical Center and other designated shuttle stops on the campus.
