(from Robert C. Bast, Jr., MD)
4FDA (Innovation or Stagnation, aka Critical Path,
Woodcock 2004)
- Explosion of knowledge from biological research,
continued growth in research spending - Slowdown in innovative therapies reaching
patients - as measured by the number of new submissions to
FDA - The drug development process has not kept up
with basic scientific innovation - 8 of drugs entering Phase I get to the market
- For drugs entering human clinical trials for the
first time between 1989 and 2002 the average
cost per new drug was 868 million in a range
from 500 million to more than 2,000 million
- Health Affairs 25, no. 2 (April 2006)

9Industry Approach Electronic Data Capture (EDC),
aka Remote Data Entry (RDE)
- 2005 82 of industry-sponsored clinical trial
data is captured using paper Case Report Forms
CDISC - EDC 1 Laptop computer
- Preconfigured with software, delivered to site
- Sponsor preference 1 (simplifies technical
support) - Sites last preference (limited real estate for
all those laptops) - EDC 2 Thin client software
- Loaded onto existing computers at site, not local
data store - Sites prefer, but central IT issue with software
installation - EDC 3 Zero footprint browser-based software
- Access CRFs online using a web browser sites 1
preference - NCI-sponsored trials have employed 2/3 for many
years - Because were stingy
10Site-based Clinical Trials Database Systems at
Large Cancer Centers
- Designed to provide institutional accountability
- All trials irrespective of sponsor
- Send data direct to NCI
- Could send data direct to industrial sponsors
- Requires lengthy per-trial negotiations
- Usually agreement is not reached
- Otherwise (i.e., usually) data must be abstracted
from the site system and entered into sponsor
forms by hand - Rekeying is the norm
- New learning curve for each new sponsor data
entry system - Site-based clinical trials database systems are
not point-of care systems they are clinical
trials databases - Someone has already had to abstract data from the
chart
11EMR as Front End to Structured Data Sources
- Most of whats in an EMR is scanned-in scribbles
and dictated clinic notes - May also contain copies of the real structured
source data - Lab, Admission/Discharge/Transfer (ADT), OT,
Pharmacy - Even if it does, may be preferable to go to
source (faster) - Result direct pairwise interfaces between
clinical source systems and clinical trials
systems - Significant human resources required to build and
maintain - Majority of clinical sources do not produce
standard data - Current HL7 standard, version 2.x, allows local
extensions - HL7 version 3 eliminates this problem, but not
yet in widespread use, at least in USA
12Starting to Lower the Barriers caXchange
- caBIG Data hub
- Transforms non-standard clinical source data into
standard HL7 Version 3 data for delivery to a
clinical trials database - Centers will only have to specify metadata
(rules for local data) - Doesnt eliminate the barrier, just lowers it
- Currently limited to laboratory data
- Lab data was born electronic, i.e., never keyed
- Lab data constitutes majority of all clinical
trial data points - However caXchange is extensible to any input data
format - Or output format, for that matter
- Goal eliminate need for proliferation of
expensive pairwise custom interfaces
13Reinventing the Electronic Medical Record
- Change in the fundamental approach to the EMR
- data in it must be structured and interoperable,
but - ability of a clinical care professional to
quickly grasp the narrative of a patient must
not be diminished - given advances in visualization techniques,
should be possible to enhance it - Being pursued as part of the US Nationwide Health
Informatics Network (NHIN) - caBIG and others are active to ensure that the
needs of clinical research stay high on the NHIN
agenda - Pay-for-Performance is a development we can
harness - Way station Pay for Data

16What is the Clinical Trials Management Systems
Workspace Trying to Achieve?
- Facilitate the planning and instantiation of
clinical trials, (and their monitoring of trials
once they are instantiated) - Facilitate the conduct of clinical trials
- Facilitate the reporting and sharing of clinical
trial data to existing/new destinations, - Achieve interoperability
- Increase the ability of systems to access and use
the data and functionality of other systems - Facilitate the integration of new sources and
destinations of data

18Library of Standard Case Report Forms based on
common data elements
- Admission end-to-end pipeline is not imminent
- Data must be entered de novo into sponsor
database via CRF (paper or electronic, standard
or non-standard) - Initiative of NCI Clinical Trials Working Group
(2005) - Standard case report forms would reduce the
need for investigative sites to manage a wide
array of different forms and data entry
processes - Standardized data capture facilitates cross-trial
analysis - Maximize capture of critically important data
- Simpler regulatory review
- One of multiple current initiatives
- e.g., CDASH Industry and FDA
- Yes, we are talking to each other
19caBIGs Special Sauce Modularity Implies
Interoperability
- Building for the next ten years Need to
interface rapidly with new data sources and
destinations - Only a set of interoperable modules is agile
enough to handle the - speed of science
- Anyone can build a
- module that plugs in if
- they build to published
- caBIG standards
- Modularity implies
- interoperability
20caBIG Clinical Trials Suite
- The caBIG Clinical Trials Suite brings together
a range of interoperable tools supporting the
clinical trials enterprise. - Functions include
- Patient Study Calendar (PSC)
- Cancer Central Clinical Patient Registry (C3PR)
- Adverse Event Reporting (caAERS)
- Laboratory Data Integration (caXchange and Lab
Viewer) - and integration with commercial clinical trials
data collection tools
Clinical Trials Suite
21Clinical Trials Suite Participant Registry (C3PR)
- Tracks subject registrations to clinical trials
- Verifies registration criteria (study open,
participant eligible, consent received) - Stratifies subject into a stratum group,
randomizes to the trial - Tracks participants across sites (handles
multi-site trials) - Manages study personnel
- Reporting (federal/local requirements, supplies
NCI Summary 3/4 data)
22Clinical Trials Suite Adverse Event Reporting
(caAERS)
- Adverse Event Tracking and classification using
accepted standards - Data import / export AE data in common/required
formats - Automated, rules-based assessment of seriousness
and reporting requirements (sponsor-level,
institution-level and protocol-level rules) - Reporting, including generation of CTEP, DCP, and
FDA compliant reports - Ability to submit electronically to CTEP AdEERS
system
23Clinical Trials Suite Patient Study Calendar
(PSC)
- Automatically generated study-template-based
patient calendar - Accurate, versioned representation of study
parameter table - Prospective forecasting of patient visit
information - Management of study participant schedules
(schedule, reschedule, cancel) - Retrospective outcomes review and reporting of
calendar activities - Consent / reconsent notification and tracking
24Clinical Trials Suite Clinical Source Data
Integration (caXchange)
- Enables automatic transfer of clinical data from
point-of-care systems in medical centers, e.g.,
clinical chemistry lab systems - Translation of multiple source data formats into
standards-compliant data for use in clinical
trials the Rosetta Stone of biomedical data - Incorporates caAdapter mapping and translation
tool to enable translation of any non-standard
source and destination format
25Clinical Trials Suite caXchange Lab Viewer
- Allows viewing of clinical lab data imported from
clinical chemistry and other lab systems (e.g.,
data extracted by caXchange) - Search by MRN and date range
- Labs can be selected for loading into clinical
trials databases and/or adverse event reporting
systems - Automatically flags lab values that may indicate
toxicities
26Building the Clinical Trials Suite
- Show that these modules can reliably exchange
information and functionality - without a huge harmonization overhead
- Complex clinical workflows dictate that the
modules must interoperate at both a syntactic and
semantic level - Subject matter experts
- define and prioritize use cases
- Analysts
- describe use cases as workflow items with data
descriptions - Developers
- translate this into working software
- Architects
- define overall governance and rules of the road
27Interoperability Use Casesidentified by Domain
Experts
- Enroll Subjects
- Load Lab Data in Clinical Data Management Systems
(CDMS) - AE Triggered Schedule Change

29Take-away Its not rocket science
- Most of it isnt even computer science
- Other industries established standards-based data
infrastructures years ago - But it is hard
- Medical data is complex consensus on semantics
is a struggle to achieve
