Three friends-Jim, Bill and Peter-- were walking down the street. Jim said, "I gave blood today." Peter said, "That's terrific! You are a scholar and a gentleman."

Bill said, "After a lot of thought, I've decided to donate a kidney." Jim said, "That's beyond terrific! You are a prince among men."

Peter said, "Well, I'm not giving blood, and I'm not donating a kidney, but I plan to enroll in a clinical trial tomorrow." Jim and Bill said, "What? Are you crazy?"

Minorities are less likely to enroll in studies compared to white males

Despite high disease burden, less than 5% of participants in Breast and Prostate Cancer prevention trials were minority

1996 to 2002 annual # of trial participants increased from 8,000-12,000 but minority participation decreased. Hispanic & Blacks represented 3.7% and 11.0% in 1996 but down to 3.0% and 7.9% in 2002

Philadelphia)-data from 2004Catchment area: 18% Black, 6% Hispanic,

UMDNJ – University Hospital (UH) dataIn 2007 there were 1132 newly identified cancer

patients: 32% white NH, 35% black NH,23% Hispanic.

There were 43 active cancer trials that enrolled a total of 54 patients, representing an overall enrollment rate of 4.8%.5.1% of blacks enrolled (20/396)4.6% of Latinos enrolled (12/260)

Thus, participation rates among racial and ethnic groups were similar at UH.

Demands of the study Preference for a particular treatment Concerns about side effects Comfort level with physician Language and literacy Loss of privacy Portrayal as guinea pig

Page 13: Reducing Disparities in Clinical Trials

Mistrust of scientific investigators and of academic institutions were major barriers among Blacks

Providing informed consent was reported as relinquishing rather than protecting rights

Research volunteer is considered a“guinea pig”

Knowledge of the Tuskegee Syphilis Study was not necessarily negatively associated with willingness to participate

Systematic review to determine barriers to participation of underrepresented populations in cancer trials: 1966-2005

Barriers to: -trial awareness-opportunity to participate (research design,

provider attitudes)-acceptance of enrollment (perceived harms,

mistrust)--additional barriers related to cultural factors

Examination of Community Members’, Researchers’ and Health Professional perceptions of barriers to minority recruitment (Robinson JM, 2007)

Cluster: Recruitment IssuesMinorities unaware of medical researchLack of cultural sensitivity in communicationsLack of resources to treat the uninsured if found to be sick Cluster: Patient concernsLack of awareness of benefits to participationSense that subjects only give and get nothingConcerns about signing ICF Cluster: Fears Fear of being a guinea pigFear of unknown

information about trialsLack of incentive for overworked MDs caring for minorities

Inappropriate outreach methods Cluster: Researcher BiasMD fear of losing patientsPoor Relationship between medical institution and

communityLack of follow-up Cluster: Issues in Research Method, Design, ManagementNot linking research to what minority communities need Lack of minorities as PILack of bilingual researchers

NIH Revitalization Act mandated minority inclusion in randomized clinical trials, 1993

Review criteria in NIH study sections have formally required minority recruitment or scientific justification for their exclusion

Rep. Edolphus Towns (Democrat, NY) was expected to submit legislation that would offer delayed generic competition to companies that conduct minority focused clinical trials.

Page 24: Reducing Disparities in Clinical Trials

Passive-disseminating information in the target population via flyers, advertisements, mailings, public service announcements

Active-bringing the project staff directly into contact with prospective participants via telephone or in-person appeals by project staff and medical providers

Page 25: Reducing Disparities in Clinical Trials

Use lay outreach workers from the targeted population (cultural insider)

Community-based organizations particularly for Blacks

Places of Worship: Although some investigators have identified religiosity as a barrier due to a fatalistic view of disease –others have found religiosity to be positively associated with willingness to participate

Page 26: Reducing Disparities in Clinical Trials

Very few patients are aware that they are eligible to participateIn a clinical trial

Page 27: Reducing Disparities in Clinical Trials

What is it? One day educational program free and open to the public

Local physician speakers provide information to help people make informed decisions about clinical research participation General session lecture –

“What Clinical Research Means to You!” Educational workshops –

focused on disease states and issues such as women or minorities in clinical research

Patient Panel – real life stories of clinical research participation

Page 28: Reducing Disparities in Clinical Trials

Purpose and Value Takes awareness-building into the heart of the

community via traditional outreach and advocacy strategies

Builds a grass-roots movement by engaging and informing political figures, opinion leaders, physicians, healthcare providers and other stakeholders

Changes perception of the clinical research participant from that of “guinea pig” to that of Hero

represented among the pool of all active clinical investigators (Getz, 2008)

Page 32: Reducing Disparities in Clinical Trials

Recruitment Strategy: Friendly Informed Consent Health literacy: degree to which people can obtain,

process and understand basic health information and services they need to make appropriate health decisions. It is not just about reading and writing, but includes all the ways people communicate health information such as by speaking, drawing pictures and using technology.

Most consents are on a 12th grade reading level Provide consent in different languages, use

“comfort” words, pictures, diagrams Voice-enhanced ICF Yates, 2009 developed a 23 page ppt flip chart for

an IC-study comparing traditional cardiac rehab vs home-based cardiac rehab-improved participation rate from 22%-54%

Page 33: Reducing Disparities in Clinical Trials

Recruitment Strategy: Clinical Trial Alert Systems Configured the EHR to trigger an alert if a patient is

likely eligible for an ongoing clinical trialCTA is set to trigger only during clinical encountersIf MD elects to proceed , a customized CTA order form

appears—reminds MD to assess a few additional eligibility criteria

MD clicks appropriate box 1) yes patient meets criteria and is interested;2. No, patient does not meet criteria; 3. No patient meets criteria but not interested. Message sent to trial coordinator’s workstation

CTA addresses obstacles to MD participation in recruitment

Page 34: Reducing Disparities in Clinical Trials

Recruitment Strategy: General Adequately characterize the target population Involve members of the target population in

planning efforts Take message to the target population Give something back to the community Enhance credibility of study by using a community

spokesperson Identify and remove barriers to participation Cultural relevance of materials Improve staff sensitivity Stress importance of prevention and early

detection Use of women to encourage participation by males

Page 35: Reducing Disparities in Clinical Trials

Mass mailing of brochures/flyers with personalized letters -across ethnic groups

Secondary source was referral by a friend for Hispanics and Blacks and newspaper ads/articles and brochures for whites

Overall recruitment through the health system produced a higher randomization yield than did newspaper and radio public service announcements or faith-based organizations

Recruits from faith-based organizations were more likely to stay in the study

Page 37: Reducing Disparities in Clinical Trials

Men—newspapers Elderly—TV and newspapers Adult children and spouses of the

patient-direct mail, newspapers, radio and online advertising

Young mothers--magazines and online advertising

Creative Get noticed Offers news Compelling message Succinct message Meaningful to patient Use Emotion Pleasing colors Catchy study name

Page 39: Reducing Disparities in Clinical Trials

Conclusions

There is equal willingness among minorities and whites to participate in clinical trials

Lack of awareness and lack of understanding of the benefits of participation are probably the biggest obstacles

Mistrust remains an issue Community involvement is imperative

for enrollment to grow
