AIM The primary objective of this study was to compare of payment estimates for participation in 4 hypothetical clinical trials between healthy volunteers and investigators of clinical research institution. In addition, the payments estimated by participants among different institutions or regions were compared.
METHODS Healthy volunteers with previous experience participating in clinical trials and investigators with previous budgeting experience for phase I clinical trial or bioequivalence study were presented and answered questionnaires regarding payment for 4 hypothetical clinical trials, its relating risk and burden, demographics.
RESULTS The study subjects consisted of 171 healthy volunteers, of whom 44% (n=75) were from Inje University Busan Paik hospital (IJUBPH), 26% (n=45) from the Seoul National University Hospital (SNUH) and 30% (n=51) from Asan Medical Center (AMC), and 40 investigator from IJUBPH (n=10), the SNUH (n=6) and AMC (n=9), and other hospitals(n=15). Healthy volunteers have estimated significantly higher payment than investigators (KRW 658,900±223,300 vs. 488,000±164,400 for Bioequivalence Study (p<0.001), KRW 1,281,500±1,176,100 vs. 812,500±266,200 for first in human study (p=0.001), KRW 1700,900±898,800 vs. 1,063,800±298,100 for Drug-Drug Interaction Study (p<0.001), and KRW 1,381,600±851,100 vs. 1,051,300±329,600 for Multiple dose PK study (p=0.004), respectively). However, no statistically significant difference was observed in comparison of payment estimates among different institutions and regions.
CONCLUSION Healthy volunteers seemed to expect higher payment for participation of clinical trials compared with investigators.
Investigators seems to consider the logistical burden as more important factors contributing to payment expectation compared with healthy subjects
The level of medical risk and logistical burden of each study scenarios, especially FIH study, have rated differently between previous report and the investigators participating in this study. The new model to evaluate the medical risk and logistical burden, and algorithm to estimate the payment in phase I clinical trials is developing.
