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

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?

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  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  Results transfer with real production data: SDO safety commitee, DRC, SSG

OVERVIEW

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
