4. Signal Management
• The process of identifying, prioritizing and evaluating
determined signals in a data population
PREVIOUS NEXT

5. Signal Detection
• The act of looking for and/or identifying signals using event
data from any source. (CIOMS, 2010 p.116)
Signal Prioritization
• The controversial act of applying plausibility criteria to
identified signals in order to place the signals in context and
apply appropriate resources. (Waller, 2010 p.50)
Signal Evaluation
• The act of formally gathering additional data to evaluate
the identified signal for the purpose of risk management.
(Waller, 2010 p. 50,51)

6. What the Industry Seeks
• A systematic approach to signal
management
 Ability to identify potential issues in clinical and post-
marketing data
 Standard prioritization questions
 Standard evaluation methods to feed risk management
 Pre-defined workflow for these processes
• A system to collect and track this
approach
 Standard system to document the identification,
prioritization and evaluation of signals
 Capability to report this process for audit answering
and justification or risk methods (document due
diligence)

7. Accel-Tracker
—Using the Empirica Suite (e-Signal and e-Topics) tool as the basic software,
BioPharm has created an accelerator that allows a company to document
the formal signal prioritization and evaluation methods suggested by the
CIOMS VIII working group and a series of decision support articles from the
literature
—The following slides will walk us through a practical example of signal
management, starting with signal identification and followed by signal
prioritization and signal evaluation, resulting in risk
identification/mitigation

8. Signal Detection
• The Empirica Suite contains the same signal detection tool (used
by the FDA) to identify potential signals based on
disproportionality reporting ratios
• As we’ve seen above, the CIOMS VIII group recommends that
signal management begins with signal detection
• This can be either data mining large repositories or identification of cases or case
series in traditional individual case safety review
• While the process begins with signal detection of individual case
safety reports, eventually the collected ICSRs become large
enough for data mining techniques; the prioritization of the
signals becomes an important aspect of signal management
(Waller, 2010, p.50)
1. Ensures focus on appropriate signals – “Hay in a hay stack”
2. Focuses appropriate resource allocation time/energy/money

9. Signal Detection Example
• Assuming we are the marketing authorization holder for
the US-marketed product Risedronate (Risedronic Acid)
▫ This is a bisphosphonate used in the treatment of degenerative
bone disease. Its mode of action is the strengthening of bone as
well as the inhibition of bone reabsorbtion.
▫ It was approved on March 27th, 1998 under the trade name
“Actonel”
• We can establish FDA/AERS queries in the e-Signal tool to
identify “hot-spots” of the MedDRA dictionary levels

10. Signal Detection Example
• In this
example, we
see an EBGM
of ~9.7 in an
interesting
SOC

11. Signal Prioritization
• The rapid review of SOC data from FDA/AERS seems to
indicate that we may have a signal for some kind of
degradation of the oral cavity warranting tooth extraction to
correct. This signal may warrant further investigation, but
we do not want to waste resources on the following:
• Known issues with the product already well documented
(expected events or well-established safety profiles)
• Co-morbidities or complications due to natural disease progression -
Disease states epidemiologically related to the treatment population
without regard to product exposure
(confounding by indication)

12. Signal Prioritization
• Prioritization of signals is a critical aspect of signal
management when mining large repositories of data
(Waller, 2010, p.50)
1. Simplifies the often daunting task of signal management
2. Focuses appropriate resource allocation time/energy/money

13. Signal Management Challenge: Where do we begin?
• No real standard in the prioritization process (Waller, 2010, p.
50)
—The WHO uses a method similar to Emergency Room triage processes in hospital
settings to quickly evaluate the aspects of a case that make it critical for research
while placing other cases on hold until a later investigation period
—The MHRA uses an analytic methodology comprised of two mathematical scores
contributing to a final score that will prioritize the case
—Other articles exist in the literature suggesting valid decision support methods

14. Accel-Tracker
—Using the e-Topics tool as the basic software, BioPharm has created an
accelerator that allows a company to document the formal signal
prioritization and evaluation methods suggested by the CIOMS VIII working
group and a series of decision support articles from the literature
—Once a signal is identified, a topic is created in e-Topics and assigned to the
appropriate work-group in a standard workflow within the system

16. Accel-Tracker
—Once the signal is placed into the initial Signal Prioritization step, the
Accel-Tracker system allows the formal prioritization, according to the
CIOMS VIII methodology and a series of decision support articles in the
literature
—This is a series of questions that allow the categorization of the signal
according to signal strength (S), novelty (N), clinical importance (I),
potential for prevention techniques (P) (CIOMS, 2010; Heeley, Waller &
Moseley, 2005; Waller, 2010; Waller, Heeley & Moseley, 2005; Waller &
Lee, 1999)

18. Accel-Tracker
—Additional
external
documentation
can also be
attached to the
topic to
support the
prioritization of
the signal

19. Accel-Tracker
—Signals prioritized as
High or Medium are
moved into the Signal
Evaluation workflow
step for further
investigation and
signal workup

20. Accel-Tracker
—Actions can be created and assigned to other users in the company
—In this example, an action to review the case series is assigned

21. Accel-Tracker
—Using e-Signal, we can drill
down into the case series
that makes up the signal of
interest
—The case series can
be attached to the
topic of interest for
historical
identification

22. Accel-Tracker
—Additional
external
documentati
on can also

23. Accel-Tracker
—After research on the signal is collected, Accel-Tracker can document
the results of evaluation through the exposure of several custom
questions designed to assist in the formal evaluation of signals
—The signal can be classified and optionally elevated to a Potential or
Identified Risk to begin the Risk Analysis and Mitigation process

24. Accel-Tracker
—Using the default abilities of e-Topics, we can run reports documenting
our signal management process at the request of a regulatory
authority or equivalent

25. Accel-Tracker
—Complete auditing of the topic case

26. Summary
—Using existing literature and Empirica Suite, configured with the Accel-
Tracker settings, we can provide a systematic method for signal
management in a single solution that accomplishes the following:
—Ability to identify potential issues in clinical and post-marketing
data
—Standard prioritization questions
—Standard evaluation methods to feed risk management
—Pre-defined workflow for these processes
—Capability to report this process for audit answering and
justification or risk methods (document due diligence)
