SCOPE OF TODAY’S PRESENTATION

• FORMATS OF REGISTER PRESENTATION

• METHODS TO ASSESS ONLINE REGISTER INFORMATION

• DETERMINING THE VALUE OF REGISTERS TO TARGET USERS

• CONCLUSIONS

REGISTER vs REGISTRY?

WHAT’S IN A NAME?

• Registry: A repository of ongoing clinical trials– www.clinicaltrials.gov

– “Clinical Trial Registry Data Bank” (FDAAA)

• Register: A repository for the results of clinical trials– www.clinicalstudyresults.org

– “Results Data Bank” (FDAAA)

THE PRACTICAL ROLE OF REGISTRIES and REGISTERS

REGULATORY INITIATIVES

• State Bills (to amend the PHS Act to expand the clinical trials drug data bank)

• *******FDAAA September 2008 Title VIII- Clinical Trial Databases********

7

The Maine Precedent

• Maine law requires manufacturers or labelers of prescription drugs to list information on clinical trials on prescription drugs that have been FDA-approved for marketing and are (or have been) dispensed, administered, delivered or promoted in Maine. Certain registration and results information must be posted on clinical trials conducted or sponsored by the manufacturer on or after October 15, 2002. The date by which the information must be posted varies depending on when the trial occurred and when the drug first enters Maine.

THE PRACTICAL ROLE OF REGISTRIES

• For federally and privately supported clinical trials conducted in the United States and around the world. ClinicalTrials.gov gives you information about a trial's purpose, who may participate, locations, and phone numbers for more details. (Sponsored by US National Institutes of Health)

10

THE PRACTICAL ROLE OF REGISTERS

• The ClinicalStudyResults.org site is a central, widely accessible, web-based repository for clinical study results in a reader-friendly, standardized format. This database will serve the valuable function of making clinical trial results for many marketed pharmaceuticals more transparent. More importantly, it is designed as a key tool to provide information to practicing physicians and their patients. (Sponsored by PhRMA)

RESULTS POSTINGS

• Welcome to ClinicalStudyResults.org!

• The ClinicalStudyResults.org site is a central, widely accessible, web-based repository for clinical study results in a reader-friendly, standardized format. This database will serve the valuable function of making clinical trial results for many marketed pharmaceuticals more transparent. More importantly, it is designed as a key tool to provide information to practicing physicians and their patients.

16

SUMMARY OF THE ROLE OF RESULTS POSTINGS

• To provide a repository of information

• To provide a balanced overview of clinical study-derived information

• To comply with regulatory requirements

• NOT intended to promote off-label uses

• NOT intended to provide conclusions

DETERMINING THE VALUE OF REGISTERS TO TARGET USERS

32

DETERMINING THE VALUE OF REGISTERS TO TARGET USERS RAISES MANY QUESTIONS

• How will health professionals use register information?– As a primary source of data?

– As a back-up to published data

• How will consumers use the information?

• What will drive users to registers?

• What will users remember from registers?

• Will register data impact knowledge and drug use?

33

UAB STUDY RESULTS

• Designed to assess how physicians use medical literature to learn about drug therapies

• CME-accredited program through University of Alabama School of Medicine

• N = 299 physicians– IM, FP, GP specialties

– Urban, suburban, rural practices

– 1 to > 20 years since medical school

34

THE UAB STUDY RESULTS

• How much time do you spend reading scientific literature each week?

1-2 hrs 30%

3-4 hrs 35%

5-6 hrs 15%

6-8 hrs 10%

>8 hrs 10%

• 65% spent up to 4 hrs reading literature

35

CONCLUSIONS

• Clinicians read in limited time, so information must be positioned:– To a target audience

– To have an impact on a thought process

– With good information concentrated in specific areas of the article

– With clear messages supported by data

36

INFERENCES FOR TRIAL REGISTERS

• Clinicians have limited time to access and interpret the information

• Clinicians can distinguish between “solid” and “weak” clinical reports

• Simplify the data presentation structure, length

• Provide valid information

• How can conclusions be drawn without regulatory conflicts?

• Need to validate new tools to assess the practical value and impact of register information
