Focus on You: Cancer clinical trials perspectives.

ABSTRACT: Clinical trials test new ways to prevent, detect, diagnose, or treat diseases. Researchers have found that minority patients are willing to participate in clinical trials, yet these patients have barriers which hinder their access to trials.To explore African American women's participation in breast cancer clinical trials, eight focus groups were conducted with breast cancer patients, family members/care givers, religious leaders, and healthcare providers to gather information on the perspectives and opinions on the topic. The focus group conversations were transcribed, and transcripts were imported into QSR International's NVivo 10 software. The transcripts were organized into folders based on four categories. The content analysis performed was based on recordings and notes.The following themes were generated as a result of conducting these focus groups and gathering information on the perspectives and opinions about participating in clinical trials, based on the groups who participated: Promoting participation in research; Personal experience with cancer; Support and support services; Awareness, knowledge, and experience with clinical trials; Providers' roles in clinical trials.The data collected in this study present several actionable themes that, if addressed by individual researchers and the medical community at large, could increase participation in clinical trials by African American patients. They also provide a deeper and more nuanced understanding of the factors influencing African American patients' decisions around participating in clinical trials.

Project description:BackgroundHistorically, clinical trials involved adding novel agents to standard of care to improve survival. There has been a shift to an individualized approach with testing less intense treatment, particularly in breast cancer where risk of recurrence is low. Little is known about physician perspectives on delivering less intense treatment for patients who are not well represented in clinical trials.MethodsOpen-ended, individual qualitative interviews with medical oncologists explored their perspectives on trials that test less intense treatment for patients with cancer, with a focus on breast cancer. Interviews were audio-recorded and transcribed. Four independent coders utilized a content analysis approach to analyze transcripts using NVivo. Major themes and exemplary quotes were extracted.ResultsOf the 39 participating physicians, 61.5% felt comfortable extrapolating, 30.8% were hesitant, and 7.7% would not feel comfortable extrapolating trial outcomes to underrepresented populations. Facilitators of comfort included the sentiment that "biology is biology" (such that the cancer characteristics were what mattered), the strength of the evidence, inclusion of subset analysis on underrepresented populations, and prior experience making decisions with limited data. Barriers to extrapolation included potential harm over the patient's lifetime, concerns about groups that had minimal participants, application to younger patients, and extending findings to diverse populations. Universally, broader inclusion in trials testing lowering chemotherapy was desired.ConclusionsThe majority (92%) of physicians reported that they would de-implement treatment for patients poorly represented in clinical trials testing less treatment, while expressing concerns about applicability to specific subpopulations. Further work is needed to increase clinical trial representation of diverse populations to safely and effectively optimize treatment for patients with cancer.Trial registrationNCT03248258.

Project description:BackgroundAdaptive clinical trials (ACTs) represent an emerging approach to trial design where accumulating data are used to make decisions about future conduct. Adaptations can include comparisons of multiple dose tiers, response-adaptive randomization, sample size re-estimation, and efficacy/futility stopping rules. The objective of this scoping review is to assess stakeholder attitudes, perspectives, and understanding of adaptive trials.MethodsWe conducted a review of articles examining stakeholders encompassing the broad medical trial community's perspectives of adaptive designs (ADs). A computerized search was conducted of four electronic databases with relevant search terms. Following screening of articles, the primary findings of each included article were coded for study design, population studied, purpose, and primary implications.ResultsOur team retrieved 167 peer-reviewed titles in total from the database search and 5 additional titles through searching web-based search engines for gray literature. Of those 172 titles, 152 were non-duplicate citations. Of these, 119 were not given full-text reviews, as their titles and abstracts indicated that they did not meet the inclusion criteria. Thirty-three articles were carefully examined for relevance, and of those, 18 were chosen to be part of the analysis; the other 15 were excluded, as they were not relevant upon closer inspection. Perceived advantages to ADs included limiting ineffective treatments and efficiency in answering the research question; -perceived barriers included insufficient sample size for secondary outcomes, challenges of consent, potential for bias, risk of type 1 error, cost and time to adaptively design trials, unclear rationales for using Ads, and, most importantly, a lack of education regarding ADs among stakeholders within the clinical trial community. Perceptions among different types of stakeholders varied from sector to sector, with patient perspectives being noticeably absent from the literature.ConclusionThere are diverse perceptions regarding ADs among stakeholders. Further training, guidelines, and toolkits on the proper use of ADs are needed at all levels to overcome many of these perceived barriers. While education for principal investigators is important, it is also crucial to educate other groups in the community, such as patients, as well as clinicians and staff involved in their daily implementation.
