Workshop on Clinical Trial Ontology

General Information

REGISTRATION FOR THIS EVENT IS NOW CLOSED!

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.

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, experimental design, 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 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) meet the requirements of the OBO Foundry, and in particular support an adequate treatment of the distinction between types (surgical intervention, tumor, human being) and instances (Jane's oophorectomy, John's tumor, Fritz)
