FDA orphan products clinical trial grants: assessment of outcomes and impact on rare disease product development.

BACKGROUND

The Office of Orphan Products Development (OOPD) of the United States (U.S.) Food and Drug Administration (FDA) has awarded over 700 grants to conduct clinical trials of medicals products for rare diseases since 1983, leading to over 70 marketing approvals. However, despite recent progress in rare disease product development, thousands of rare diseases still have no approved treatments. An assessment of this clinical trial grants program was undertaken to provide an in-depth analysis of the characteristics and outcomes of the program. Results of this analysis will be used to inform future goals of the program, as well as internal data collection to continue to maximize the program's impact in supporting rare disease product development.

RESULTS

Between fiscal years 2007-2011, OOPD funded 85 clinical trial grants. These grants spanned 18 therapeutic areas, included all pre-approval phases (Phases 1-3), and approximately 75% of the grants studied small molecule drugs. Nine (11%) product approvals, of seven drugs and two devices, were at least partially supported by grants funded within this 5-year timeframe. Four of the seven drugs approved were new molecular entities (NMEs). The average time from funding to approval was seven years. We also found a suggested association between collaboration with multiple types of stakeholders and the success of grants, where we defined success as either positive or negative study findings or a future marketing approval.

CONCLUSIONS

The clinical trials funded by OOPD provided valuable information for future product development, and there were a notable number of approvals that occurred using the support of the grants program. There was a suggested association between collaboration and successful outcomes. Efficient and innovative trial designs and collaboration among stakeholders appear vital to continue to effectively bring products to rare disease patients. Ongoing program assessments will ensure that the funding continues to be used to optimally meet the treatment needs of the rare disease community.
