Distrust Of Trials Declining Among Minority Populations

Tuesday, September 26, 2017

Distrust of pharma companies and clinical trials has long been cited as one reason for the low enrollment numbers of minorities in clinical studies. But a new survey finds that lack of trust may be waning, while other factors continue to contribute to low participation rates.

According to a recent public opinion survey commissioned by Research!America, significantly fewer African-Americans, Hispanics, Asians, and non-Hispanic whites say “lack of trust” is a reason why they opt to not participate in clinical trials. This seems to indicate a more favorable perception of clinical research. In fact, the percentage of respondents citing “lack of trust” as a reason for not participating declined by as much as 15 percent among minority groups and the population overall, when compared to the results of a 2013 survey. The survey found 50 percent of African-Americans (11 percent decrease), 45 percent of Asians (6 percent decrease), 43 percent of Hispanics (9 percent decrease), and 39 percent of non-Hispanic whites (15 percent decrease) cited lack of trust as a factor for non-participation.

A similar trend was noted when respondents were asked about participation in trials. When asked if they or someone in their family has ever participated in a clinical trial, the percentage of African-Americans who responded “yes” showed a marked increase from 15 percent to 22 percent. Among other groups, the percentages either increased slightly or remained the same.

Of continuing concern to pharma is the fact that less than a quarter of respondents in any group responded “yes,” although a large majority noted they would be likely to participate in a clinical trial if their doctor found one and recommended it to them. That number was highest for non-Hispanic whites (85 percent), with slightly lower numbers for Hispanics (81 percent), African-Americans (74 percent), and Asians (73 percent).

Lack Of Information A Problem

If lack of trust is declining as a factor that is keeping patients from trials, what is the concern for potential patients? The survey found about half of minority group respondents (as well as non-Hispanic whites) citing “lack of information” as a reason they do not participate in clinical trials. That factor remained largely unchanged from the 2013 survey. Getting trial information to patients is a challenge for pharma companies and will likely continue to be in the future. The survey found the organization or group that a majority of patients feel has the greatest responsibility for educating the public about clinical trials is doctors and healthcare providers.

While doctors and healthcare professionals are the individuals most trusted by patients, they unfortunately do not spend a lot of time promoting trials to patients. A significant percentage of minority group respondents and non-Hispanic whites do not cite doctors and healthcare providers as a reliable source for clinical trial information. Only 27 percent of Hispanics, 25 percent of Asians, 24 percent of African-Americans, and 15 percent of non-Hispanic whites say their doctor or other healthcare professional has ever spoken to them about medical research. On a positive note, all groups agreed that healthcare professionals should discuss clinical trials with patients diagnosed with a disease as part of their standard of care. That figure was highest for Hispanics (89 percent) and lowest for African-Americans (79 percent).

Pharma companies and regulators agree that to develop medicines that are safe for the general population, clinical trial participants need to be a mix of races and genders. In fact, research has shown that ethnicity is one factor that may account for observed differences in both pharmacokinetics and pharmacodynamics of drugs. The willingness of minorities to participate in trials also means the days of trials being packed with white males may come to an end.

The survey found a strong majority of minority respondents would be willing to share personal health information so researchers can better understand diseases and develop new ways to prevent, treat, and cure patients. It also found minority patients would be willing to share that information to improve patient care and advance medical research so public health officials can better track diseases and their causes.

Technology advancements are also not a sticking point for minority patients. The survey found 75 percent of Hispanics, 69 percent of African-Americans, and 68 percent of Asians are likely to use technology to share personal health data. Additionally, minority groups say they would prefer to have clinical trial information/data/results delivered through their phone. That figure ranged from 58 percent of Hispanics to 50 percent of Asians. Approximately half of all groups noted they have heard about clinical trials from the Internet.
