Here are some tips for How to share your SAS knowledge with your professional network.
Solutions in the Round -- DATA = CLINICAL; (WUSS)
From the WUSS abstract for this topic
This session will discuss recent trends in the pharmaceutical industry. CDISC, ADaM, investment in Real World Evidence will be potential topics in this “all things clinical” discussion. Solutions in the Round (SITR) is a roundtable format section where attendees discuss approaches and solutions to a programming problem or SAS topic. Users from different perspectives and all experience levels are encouraged to participate.
Discussion at WUSS
Richann Watson (RW), SAS

- parent of CDISC for medical devices
- Definitions ( Controlled terminology ):
CDISC == Clinical Data Integration Standards Corporation
SDTM == Submitted Data Tabulation Model
ADaM == Analysis Data Model
CDASH == Corrrelation for Data Acqusitions,
TAUG == Therapeutic Area User Guide
- Clinical Trials Data need traceability & reproducibility
FDA reproduce efficacy & safety endpoints
- If match, then review results
- If not, return to sponsor
- What issues with CDISC?
- Pinnacle 21 tool mismatches with variable labels
-- use SDRG, ADRG (reviewer guides)
-- tool doesn't always match FDA rules
-- community vs enterprise ($$)
Q: Is there a way to save results outside of community folder?
RW: Submit suggestion to Pinnacle 21 group
- filenames are long and very similar for SDTM, ADaM, etc.
CS: What problems with storing data that does not fit
CDASH v2.0 -- better mapping for SDTM than v1.0
== Collection, case reports
-> saves a LOT of explanations in SDRG (can say "used CDASH")
Q: Defines mappings
RW: use defines
- create them EARLY!
- Helps you along the way
CS: "Keep define in mind" early in study for ADaM
Q: When working on ADaM datasets, just run ADaM alone for Pinnacle
RW: Need to submit STDM with ADaM for Pinnacle 21
- include DM, EX, DS, AE tables
CS: Medical group
- add CDRH to CDISC group
- Worked with a presenter from CDRH to show CDISC solutions for lack of standardized sponsor submissions
Q: Use PhUSE for SDRG and ADRG
FDA: Strongly recommend PhUSE templates
RW: includes ammendments, can explain 2 waterfall analyses for oncology studies
CS: Have to *fix* isssues, not just report them.
- Explain AE after close of study (last disposition date)
- FDA has tools beyond Pinnacle 21
-- find hidden data
-- "data fitness"
-- "data quality"
TLF "Fit" data needs little or no data programming in TLF
CRF --> STDM --> ADaM
RW: ADaM == "1 PROC away" from results
RW: not analyses
- Listings from ADaM or STDM
-- More complex from ADaM
-- Else, from STDM
Safety populations from AD AE
-> STDM or ADaM for listings
-> original data / standard data
-> can bring STDM variables to ADaM for easier listings
-> avoid listings from merges (FDA cannot easily reproduce)
-> Do not create ADaM solely for listings (e.g. medical history)
-> use STDM image domain
Q: Data that does not fit standard domains?
May need "type C" letter / meeting (communication) (pre-NDA)
- Have this type of data, plan to use custom domain: is this acceptable?
CS: Engage FDA early, engage FDA often
Custom Study Standardization Plan (early in plan, phase 1 .. 3)
Upcoming Presentations by Facilitators
- Underutilized aspects of CDISC
- Avoiding ADaM sinkholes
