Quantifying Site Burden to Optimize Protocol Performance

BACKGROUND

The increase in protocol complexity and the resulting rise in the effort required by investigative sites to implement protocols have been well documented, but existing measures of site burden only offer an incomplete view of the burden experienced by site personnel. The introduction of Decentralized Clinical Trials-trials supported by remote and virtual technologies and services-is expected to impact the burden imposed on sites, but this impact has not yet been systematically measured.

METHODS

The Tufts Center for the Study of Drug Development conducted an online survey among clinical research sites worldwide and gathered 355 responses assessing the burden associated with distinct activities and procedures related to the implementation of clinical trial protocols using traditional and decentralized approaches.

RESULTS

A high percentage of investigative sites (50.5%) have had no experience with DCT solutions and only a small percentage (6.6%) have participated in fully decentralized clinical trials. Overall, half of respondents view DCT solutions as more burdensome than traditional clinical trials. In general, activities related to operational and managerial aspects of trial implementation were viewed as less burdensome when done remotely, while clinical procedures or elements that require study team-patient interactions were viewed as more burdensome when using DCT approaches versus in-person or traditional methods.

Systematic review on costs and resource use of randomized clinical trials shows a lack of transparent and comprehensive data

OBJECTIVES

Randomized clinical trials (RCTs) are costly. We aimed to provide a systematic overview of the available evidence on resource use and costs for RCTs to support budget planning.

STUDY DESIGN AND SETTING

We systematically searched MEDLINE, EMBASE, and HealthSTAR from inception until November 30, 2016 without language restrictions. We included any publication reporting empirical data on resource use and costs of RCTs and categorized them depending on whether they reported (i) resource and costs of all aspects at all study stages of an RCT (including conception, planning, preparation, conduct, and all tasks after the last patient has completed the RCT); (ii) on several aspects, (iii) on a single aspect (e.g., recruitment); or (iv) on overall costs for RCTs. Median costs of different recruitment strategies were calculated. Other results (e.g., overall costs) were listed descriptively. All cost data were converted into USD 2017.

RESULTS

A total of 56 articles that reported on cost or resource use of RCTs were included. None of the articles provided empirical resource use and cost data for all aspects of an entire RCT. Eight articles presented resource use and cost data on several aspects (e.g., aggregated cost data of different drug development phases, site-specific costs, selected cost components). Thirty-five articles assessed costs of one specific aspect of an RCT (i.e., 30 on recruitment; five others). The median costs per recruited patient were USD 409 (range: USD 41-6,990). Overall costs of an RCT, as provided in 16 articles, ranged from USD 43-103,254 per patient, and USD 0.2-611.5 Mio per RCT but the methodology of gathering these overall estimates remained unclear in 12 out of 16 articles (75%).

CONCLUSION

The usefulness of the available empirical evidence on resource use and costs of RCTs is limited. Transparent and comprehensive resource use and cost data are urgently needed to support budget planning for RCTs and help improve sustainability.
