Trial History

Other than the financial motivations for enrolling in Phase I trials, research on how healthy volunteers perceive the benefits of their trial participation is scant. Using qualitative interviews conducted with 178 U.S. healthy volunteers enrolled in Phase I trials, we investigated how participants described the benefits of their study involvement, including, but not limited to, the financial compensation, and we analyzed how these perceptions varied based on participants’ sociodemographic characteristics and clinical trial history. We found that participants detailed economic, societal, and noneconomic personal benefits. We also found differences in participants’ perceived benefits based on gender, age, ethnicity, educational attainment, employment status, and number of clinical trials completed. Our study indicates that many healthy volunteers believe they gain more than just the financial compensation when they accept the risks of Phase I participation.

The Republic

The phase I trial is the first step in administering a drug to humans, but it has no therapeutic purpose. Under the absence of therapeutic purpose, healthy volunteers demonstrated different motivations, unlike the actual patients participating in trials. There were many reported motivations, such as financial motivation, contributing to the health science, accessing ancillary health care benefits, scientific interest or interest in the goals of the study, meeting people, and general curiosity. The aim of this study was to identify the motivation and characteristics of healthy volunteers participating in phase I trials in the Republic of Korea. We gave surveys to 121 healthy volunteers to study their demographic characteristics and the reasons of participation. We identified whether the decision to participate in the research was influenced by demographic factors and whether the perception and attitudes toward the research were influenced by the characteristics of the healthy volunteers. After completion of the first survey, 12 healthy volunteers who had participated in a phase I clinical trial were selected to answer the second interview. According to our survey, most healthy volunteers were unmarried men and economically dependent. Most of them participated in the study because of financial reward. The most important factor to measure financial reward was the research period. Also, 43% of the volunteers were university students, 42% answered “university graduation” and 55% were residing in family-owned houses. Many healthy volunteers were found to be living in family homes and to have a student status or lack of economic independence. Results of the survey showed that 64% of respondents indicated having more than one clinical trial participation. In-depth interviews showed that healthy volunteers had diverse motivation to participate in research and that healthy volunteer perceive the clinical trial positively. The main motivation for healthy volunteers’ participation in research was “financial reward.” Healthy volunteers also considered research schedules, processes, and safety, and had a positive perception of clinical trials, but they thought that the public has a negative perception.

Aims/Background A fundamental part of all clinical trials is informed consent, reflecting the respect for the volunteer’s autonomy. Research participation is voluntary; therefore, certain aspects of the proposed study must be disclosed so that volunteers can make an informed decision. In this study, we aimed to examine the level of comprehension and recall of healthy volunteers from the informed consent process. Methods The study was carried out at a single phase I clinical trials unit. A questionnaire was administered to each volunteer to assess recall of important aspects of the study at the day-1 visit following the informed consent process. The questionnaire contained seven questions regarding study objectives, route, frequency and type of drug administration, adverse effects, number of subjects previously exposed and remuneration. One point was awarded for each correct answer. Results A total of 266 volunteers were administered the questionnaire. The mean total score (±standard deviation) for all volunteers was 4.5 ± 1.1 points out of 7, with a range of 0.8–6.7. For all 10 studies, 91% of volunteers responded correctly when answering about the route of administration, and 90% were able to accurately state the correct payment amount. Only 7% were able to repeat the aims of the study correctly. Conclusion The poor performance of our study volunteers raises concerns about recall of information prior to study drug administration. This has implications for the volunteer’s safety and ability to provide true informed consent. Interventions to improve recall prior to dosing should be undertaken.
