Data Management for Pharmaceutical Trials Michael A. Kohn, MD, MPP (Acknowledgment: Susanne Prokscha)
Final Project: Part ASend in or Demonstrate Your Study DatabaseDue 9/18/2013 Send in a copy of your research study database*. We prefer a database that you are currently using or will use for a research study. However, a demonstration or pilot database is acceptable. *If you are unable to package your database in a file to email, you can send us a link or work out another way to review your database.
Final Project: Part BSubmit Your Data Management PlanDue 9/18/2013 • General description of database • Data collection and entry (Forms) • Error checking and data validation • Reporting (e.g. NIH Report) • Analysis (e.g., export to Stata) • Security/confidentiality • Back up
Final Project (12 Questions) 1) What is your study? ("The [CUTE ACRONYM] study is a [DESIGN] study of the association between [PREDICTOR] and [OUTCOME] in [STUDY POPULATION]"). 2) What data points are you collecting? (Your data collection forms.) 3) Who collects the data? You? RAs? MDs? Chart abstractors? Maybe the study subjects enter the data themselves?
Final Project (cont’d) 4) How are the data collected? Written onto a paper form and then transcribed into a computer database? Entered directly into the computer? (If data are transcribed, who does it? Have you hired/will you hire somebody? Or have you enlisted/will you enlist some med students?) 5) Will the above-mentioned computer database be in Access, REDCap, QuesGen, Oncore, OpenClinica, SurveyMonkey, Medidata RAVE, or something else? 6) Try to provide a detailed data dictionary with the name, data type, description, and validation rules for each field (column) in the data table(s).
Final Project 7) If it's a multi-table database, even a hand-drawn relationships diagram would help but is not required. 8) How do you validate the data for correctness and monitor the data collection effort? (Usually you have some range checks on individual variables and you periodically query for outliers that are nonetheless within the allowed range.) 9) How will you create reports like the NIH Report? 10) You should periodically analyze the data, not only to look for problems, but also to see where the study is headed. How do/will you do this? Query in Access and export to Stata? 11) How will you protect your subjects' identifying data? 12) How will you ensure that you don't lose your data file in a computer crash or if a water pipe leaks?
Answering these 12 questions is an essential part of doing a clinical research study.

Jargon from the Clinical Trials World • EDC (electronic data capture) • eCRFs (electronic case report forms) • CDM (Clinical Data Management) • Edit checks (validation rules) • Queries (can mean SQL queries of data tables or questions to study sites to clarify data) • AE (Adverse Event), SAE (Serious Adverse Event) • CFR 21 Part 11 (Code of Federal Regulations, Chapter 21, Part 11)
CFR 21 Part 11 • Required for submission of electronic data to the FDA when applying for drug or device approval • Audit trail of all data entries, updates, and deletions.
EDC Regulatory Environment Any system used to collect data that may be included as part of an NDA to the FDA must be compliant with 21 CFR Part 11 – the rule on electronic records and signatures. The rule includes system requirements such as: Time-stamped, automatic audit trail Secure account management and access controls The rule also includes procedural elements: System and study level validation Standard operating procedures
Case Study Large Phase III Trials at Genentech
Study Startup – Prep for “First Patient In” Study startup activities begin when the protocol summary is firm and rely on the final protocol to move forward until it is ready for subject data. Specify and build the eCRF There will be 50-75 unique eCRFs for a Phase III study Specify and build the edit checks There can be from 600 to 2000 individual edit checks Estimate 1000 edit checks for a Phase III study Test the study application and release for production (“go live”)
Study Conduct – Collect and Clean Data Study conduct runs from first patient in to lock. Monitor site entry of data and responses to queries Perform Data Reviews Some checks are more easily done by a humans via listings or reports Medical review is performed by clinical science Create Manual queries Example: MS Phase III trial with 105 sites and 450 subjects had 5000 manual monitor and data review queries Example: Phase II trial with 32 sites and 120 subjects had about 800 manual queries
Study Conduct – Other Activities Collect non-CRF data (labs, etc.) Code adverse events and medications Collect and reconcile serious adverse events against the safety database An important event during study conduct that occurs in most Phase II and III trials is a database change or “amendment”. Most studies have multiple amendments. Genentech estimates a cost of $60-70,000 per amendment.
Study Closeout – Prepare for Lock Preparation for lock of a study often begins prior to last patient “out” and must be complete before lock. Ensure data is complete (both eCRF and non-eCRF) Perform final data reviews Final Data listing review Review all coding assignments Check that all SAEs are accounted for Obtain resolution for, or close, all open queries Obtain Principal Investigator Signature Prepare archival versions of eCRF for the sites and the sponsor files
Data Management Impact Even though data management is only 12% of the cost of a large trial, it is an essential component. If the data is not complete or accurate enough to be analyzed and sustain a conclusion, then the entire trial cost is wasted.
