OVERVIEW
n Introduction
n Secure Data Office tasks § Randomisation Data § The Pharmacokinetic (PK) Data flow § Other unblinding data streams § Cleaning of unblinding data § Deliver blinded result transfers § Deliver data to unblinded teams
n Conclusion
4
INTRODUCTION
n Double blind study: § Subject and investigator are unaware of treatment status § Parties without access to unblinding data: subjects,
investigators, data management, statistics, PK analysts, sponsor
§ Parties with access to unblinding data: pharmacists, bio-analysis lab, unblinded CRA
n Unblinding data: § Any data that can unblind the study
• Treatment information • Pharmacokinetic data • Immunogenicity data • Biomarkers • ....
5
INTRODUCTION (2)
n Downside: § Unblinding data is not cleaned § Delay in clinical database lock or unblinding data are not
included in lock § Crunched timelines for some parts of the analysis
6
Who should handle randomisation data and other unblinding data (e.g. PK, biomarker,
immunogenicity data)?
7
SD OFFICE
n Dedicated team, physically separated from other study team members
n Secure server locations and separate databases
n Clearly defined processes in SOPs and WIs

OVERVIEW
n Introduction
n Secure Data Office tasks § Randomisation Data § The Pharmacokinetic (PK) Data flow § Other unblinding data streams § Cleaning of unblinding data § Deliver blinded result transfers § Deliver data to unblinded teams
n Conclusion
9
RANDOMISATION DATA
n Generation of randomisation lists § Documented randomisation list specifications § By SAS programmers with statistical background § Distribution to required recipients
n Creation of SDTM datasets containing randomisation information based on following input § Receive randomisation information: from external vendor or
internally created § Subject information: from data management
10
PK DATA FLOW
n PK data is always unblinding
n PK data (Identifiers and results): bio-analysis lab SDO
n Blinded transfers: SDO Data Management (DM)
n Cleaning is performed by DM
n DM delivers clean PC file to SDO § Contains CRF and sample tracking data § Without results
n SDO delivers clean PC file with results to include at time of DB lock

OTHER UNBLINDING DATA STREAMS: LAB DATA
n Similar to PK data stream
n Only unblinding analytes via SDO
n SDTM domains: LB, PD, IS
n DM unblinded at release § Yes: combine LB parts by DM § No: combine LB parts and release by SDO
17
OTHER UNBLINDING DATA STREAMS: PROTOCOL DEVIATIONS
n Identification of unblinding protocol deviations (usually medication kit errors)
Protocol deviation defined asAny medication kit
misallocationOnly treatment misallocations
Medication kit number unblinding?

18
OTHER UNBLINDING DATA STREAMS: PROTOCOL DEVIATIONS
n Assigned medkit = planned data
n Dispensed medkit = actual data
n Reconciliation of planned and actual data by SDO
n SDO creates part of the DV domain: § Deviations related to medkit or treatment misallocations
19
CLEANING OF UNBLINDING DATA
n Only if cleaning of the unblinding content is required
n Cleaning requirements: in secure data handling plan
n Cleaning Checks are: § Defined § Documented § Programmed § Validated § Ran
n Review output of checks
n Write and follow up queries: blinded/unblinded
20
DELIVER BLINDED RESULT TRANSFERS
n PK data (Identifiers and results), other unblinding data: external vendor SDO
n Blinded transfers: SDO Data Management (DM)
n Cleaning is performed by DM
n Results transfer with dummy identifiers/scrambled : SDO statistics, PK analysts: dry runs
21
DELIVER DATA TO UNBLINDED TEAMS
n PK data (Identifiers and results), other unblinding data: external vendor SDO
n Blinded transfers: SDO Data Management (DM)
n Cleaning is performed by DM
n Results transfer with real production data: SDO safety commitee, DRC, SSG
22
OVERVIEW
n Introduction
n Secure Data Office tasks § Randomisation Data § The Pharmacokinetic (PK) Data flow § Other unblinding data streams § Cleaning of unblinding data § Deliver blinded result transfers § Deliver data to unblinded teams
n Conclusion
23
CONCLUSION
n Role of SD Office § Create randomisation lists and datasets § Clean data before database lock
• PK data • Medication kit misallocations • Other unblinding data
§ Prepare input files for PK/PD analysis upfront -> analysis can start earlier
n Results § Time gain after lock § Higher quality § Unblinded data available before lock for DRC, SSG, dry runs § Off the critical path and key results can be met
