Dropout Rates for Oncology Phase I Trials Remain Under 10%
Oncology trials are in line with average dropout rates, but percentages rise as required visits increase
RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--The overall dropout rate for oncology Phase I trials is very low at only 8%, a study by Cutting Edge Information found. However dropout rates tend to rise as the number of required visits increases.
"one interviewed executive conducting a diabetes trial reported 200 enrolled patients, many more than any other trial"
The study, "Phase I Clinical Trials: Optimizing Cost-Drivers for Clinical Pharmacology Programs," discovered that the average number of patients enrolled for these trials across all therapeutic areas is 47.2.
Surveyed companies report as few as 15 patients enrolled in their Phase I trials. However, "one interviewed executive conducting a diabetes trial reported 200 enrolled patients, many more than any other trial," said Ryan McGuire research team leader at Cutting Edge Information. "Though the diabetes trial had the highest patient enrollment, its total costs are 2.5 times less the overall average. Patient recruitment was likely easy for this therapeutic area, and the trial required only four patient visits."
The next highest number of patients came from an oncology clinical trial. Initial patient enrollment ranged from 15 to 106, much higher than the average for Phase I trials. Across the other therapeutic areas, including cardiovascular, gastroenterology and women's health, average enrollment was generally between 20 and 40 subjects.
The study reveals the average number of patients completing Phase I trials by therapeutic area:
Oncology trials align with the average dropout rate at 8%.
Central nervous system/neurology trial results show a dropout rate at 7%.
Women's health trials appear to have a high average dropout rate at 16% — double this study's overall average.
"Phase I Clinical Trials: Optimizing Cost-Drivers for Clinical Pharmacology Programs," (http://www.cuttingedgeinfo.com/research/clinical-development/phase-i-clinical-trials/) examines the critical cost drivers when budgeting for Phase I trials. The research includes key performance metrics, including Phase I budgets and staffing, as well as an analysis of data collected from 30 Phase I clinical trials. Use this report to:
