Abstract

An Internet-based clinical trial management center (FIG. 1) that communicates with a base of users (12), participating in a clinical trial and enables the users to access and manage data (49), as well as obtain the products of data processing (40), according to each user'"'"'s role in the clinical trial. The management center (40) captures data from different data sources, that is, user-operational devices, and transforms the data into a common format for storage in a database (49). Data processed by the management center (40) is converted from the common format to one suitable for a receiving device operated by the user (12) who is to receive the data. At a workflow level, the management center implements a clinical data interchange pipeline (CDIP) to allow data to be transported in a flow in a given direction and intercepted throughout its flow for processing by applications having different formats and transport protocols in a seamless manner.

Claims

1. A method for managing a clinical trial, comprising:

enabling information exchanges over an Internet-based network with users participating in a clinical trial;

deploying over the Internet-based network for use by the users clinical trial setup information including tools to automate creation of a data repository;

providing to the users over the Internet-based network, collaborative clinical trial setup and administration functions which allow the users to use the clinical trial setup information to collaborate with each other and administer the clinical trial; and

performing clinical trial management functions to add intelligence to clinical trial data received in the information exchanges.

2. The method of claim 1, further comprising:

capturing the clinical trial data in different formats from a plurality of data sources;

transforming the clinical trial data from the different formats to a common format for storage in the data repository; and

converting the clinical trial data stored in the data repository from the common format to another format suitable for a receiving device operated by a user to receive such clinical trial data.

4. The method of claim 1, further comprising:

generating an audit trail to track changes in the clinical trial data.

5. The method of claim 1, further comprising:

enabling the users to customize workflow related to processing of the clinical trial data.

6. The method of claim 1, further comprising:

defining clinical trial parameters to denote aspects of clinical trial performance; and

updating the clinical trial parameters during the clinical trial on a real-time basis.

7. The method of claim 2, wherein converting converts the clinical trial data from a common format to different formats for rendering to user-operated devices of different form factors.

8. The method of claim 1, further comprising:

associating with each user a username and password;

assigning to each user a clinical trial role and trial site;

using the username and password to validate each user for authentication at a level of data access; and

using the clinical trial role and trial site to validate each user for authentication at a different level of data access.

3. The method of claim l, further comprising:

providing processing nodes sharing a common interface and adapted to communicate with applications having different interfaces; and

organizing the processing nodes into a pipeline structure to support a flow of clinical data objects in a given direction, each processing node within the pipeline structure using the common interface to allow the flow of the clinical data objects to be directed out of the pipeline to one of the applications for processing and reintroduced into the pipeline structure through that node.

9. A data interchange method, comprising:

providing processing nodes sharing a common interface and adapted to communicate with applications having different interfaces; and

organizing the processing nodes into a pipeline structure to support a flow of data objects in a given direction, each processing node within the pipeline structure using the common interface to allow the flow of the data objects to be directed out of the pipeline to one of the applications for processing and reintroduced into the pipeline structure through that node.

10. A method of operating a medical imaging system in a clinical trial environment having a clinical trial server for storing clinical trial data from users participating in a clinical trial, comprising:

communicating with the clinical trial server to download images from among the stored clinical trial data;

authenticating users into the clinical trial system based on user privileges associated with the users;

analyzing the images; and

providing results of the analyzing to the clinical trial server over a secure Internet link for integration with the stored clinical trial data.

11. A clinical trial management system, comprising:

an application server configured to perform clinical trial management functions;

a Web server coupled to the application server and having an interface to facilitate access to the clinical trial management functions over an Internet-based network by users participating in a clinical trial; and

wherein the interface controls access to the clinical trial management functions by each user according to dynamic access rights associated with a clinical trial role assigned to the user.

12. A clinical trial management system, comprising:

an arrangement of servers capable of responding to user requests from users participating in a clinical trial, the arrangement being scalable to serve an increasing number of the users concurrently by coupling additional servers; and

wherein the arrangement maintains user session information in a database tier to provide for load sharing between at least two of the servers.

13. A clinical trial management system, comprising:

a server for capturing clinical trial data from users participating in a clinical trial; and

a graphical interface, coupled to the server, to allow the users to customize workflow related to processing of the clinical trial data.

14. A computer program product residing on a computer-readable medium for managing a clinical trial, the computer program comprising instructions causing a computer to:

enable information exchanges over an Internet-based network with users participating in a clinical trial;

provide to the users over the Internet-based network collaborative clinical trial setup and administration functions which allow the users to use clinical trial setup information to collaborate with each other and administer the clinical trial; and

perform clinical trial management functions to add intelligence to clinical trial data received in the information exchanges.

15. The computer program product of claim 14, further comprising instructions causing a computer to:

generate an audit trail to track changes in the clinical data.

16. The computer program product of claim 14, further comprising instructions causing a computer to:

enable the users to customize workflow related to processing of the clinical trial data.

17. The computer program product of claim 14, further comprising instructions causing a computer to:

define clinical trial parameters to denote aspects of clinical trial performance; and

update the clinical trial parameters during the clinical trial on a real-time basis.

18. The computer program product of claim 14, further comprising instructions causing a computer to:

transform clinical trial data from different formats to a common a for storage in a data repository; and

transform the clinical trial data from the common format to different formats for rendering to user-operated devices of different form factors.

19. The computer program product of claim 14, further comprising instructions causing a computer to:
