    Background

    Pivotal trials, the clinical studies that inform U.S. Food and Drug Administration (FDA) approval decisions, provide the foundational evidence supporting the safety and efficacy of novel therapeutics. We determined the representation of the elderly, women, and patients from racial and ethnic minorities in pivotal trials and whether the FDA is making subgroup efficacy analyses among these subpopulations available to the public.

    Methods

    We conducted a cross-sectional study of novel therapeutics approved by the FDA between 2011 and 2013. Using publicly available FDA documents, we collected information on the demographic characteristics of pivotal trial participants (age ≥65 years, sex [male, female], race [white, black, Asian, other], and ethnicity [Hispanic, non-Hispanic]) and determined the availability of subgroup analyses by age, sex, race, and ethnicity.

    Results

    We identified 86 novel therapeutic that were approved by the FDA between 2011 and 2013 for 92 indications on the basis of 206 pivotal trials. The median age of pivotal trial patients was 53.1 years (interquartile range 40.6-60.6), and the mean proportion of patients ≥65 years of age was 28.9 % (95 % CI 23.5-34.4 %). Similar proportions of pivotal trial participants were male (mean 50.3 %, 95 % CI 45.3-55.2 %) and female (mean 49.7 %, 95 % CI 44.7-54.7 %). Most participants were white (mean 79.2 %, 95 % CI 75.9-82.6 %), while the mean proportion of black patients was 7.4 % (95 % CI 5.5-9.3 %), that of Asian patients was 7.4 % (95 % CI 5.2-9.7 %), and that of patients of other races was 5.9 % (95 % CI 4.4-7.5 %). Information about ethnicity was available for only 59.8 % of indications, and where such data were available, the mean proportion of Hispanic participants was 13.3 % (95 % CI 10.3-16.3 %). FDA reviewers performed and made available subgroup efficacy analyses by age, sex, and race for at least one of the pivotal trials used as the basis of approval for over 80 % of indications.

    Conclusions

    Although women are equally represented in pivotal trials supporting recent novel therapeutic approvals by the FDA, elderly patients and those from racial and ethnic minorities are underrepresented. FDA reviewers generally perform subgroup efficacy analyses by age, sex, and race and make these subgroup analyses available to the public.

    Stakeholder Perspectives on the Use of Community Health Workers To Improve Palliative Care Use by African Americans with Cancer.
    (Journal of palliative medicine, 2019-03) Johnston, Fabian M; Neiman, Joseph H; Parmley, Lauren E; Conca-Cheng, Alison; Freund, Karen M; Concannon, Thomas W; Smith, Thomas J; Cooper, Lisa A

    Background

    African Americans in the United States have worse end-of-life care and cancer outcomes than whites. Palliative care may improve this disparity. Community Health Workers may provide a means to improve palliative care disparities.

    Methods

    Semistructured in-depth interviews (five) and stakeholder focus groups (four) were conducted with cancer patients, caregivers, health care administrators, oncologists, and community health workers (CHWs). Patients were recruited through snowball sampling. Three raters coded interviews independently. Data were analyzed using interpretative phenomenological analysis.

    Results

    Seventy-one individuals were contacted to participate with 24 stakeholders (34%) participating in individual interviews or across 4 stakeholder engagements. Eleven constructs were identified and grouped in three broader themes: "hub of the wheel," understanding palliative care, and patient-provider relationships. Participants felt that the role of a CHW should be central, bridging patients with their providers, information, and resources, including psychosocial support and advance care planning documents. They also placed an emphasis on the background of CHWs, saying individuals selected should be familiar with the history, culture, and norms of the communities from which they operate. Stakeholders reported that a CHW could activate a patient to contact their primary care physician or oncologist who may refer to or provide palliative care. Stakeholders reported that given the barriers to palliative care, a CHW could contribute to patient-centered multidisciplinary care while addressing palliative care domains with patients and families in a culturally sensitive manner.

    Conclusion

    Based on feedback from patients, caregivers, and providers, a culturally adapted CHW intervention may improve palliative care use for African American patients with advanced malignancies.
