FDA Releases Draft Guidance to Enhance Clinical Trials for Opioid Use Disorder Medical Devices

The U.S. Food and Drug Administration (FDA) has taken a significant step in the fight against the opioid crisis by releasing a draft guidance aimed at improving the design of clinical trials for medical devices targeting Opioid Use Disorder (OUD). The new guidance, issued recently, seeks to address challenges such as inaccurate self-reported drug usage, data gaps, and the necessity to demonstrate treatment durability in OUD trials.

Recognizing the complex landscape of OUD trials, the FDA hopes that this guidance will pave the way for more effective development of medical devices to combat opioid addiction. The agency acknowledges that the struggle to gather critical data for OUD devices has highlighted several therapeutic area-specific issues, all of which the draft guidance intends to tackle head-on.

FDA Commissioner Robert Califf emphasized the importance of this initiative, stating, "This draft guidance for device studies should prompt industry to collect more comprehensive, timely, and diverse data to support device submissions that may help improve the lives of those with opioid use disorder."

One of the core concerns addressed by the draft guidance is the potential impact of subjective outcomes, placebo effects, concomitant therapies, and biases on OUD device trials. To mitigate these issues, the FDA recommends pivotal studies with well-defined participant cohorts, rigorous drug use monitoring, controlled biases, and appropriate follow-up periods.

Throughout the document, the FDA provides insight into how sponsors can effectively achieve these goals. The agency advises sponsors to assess opioid use through both self-reports and "objective verification measures." These measures include random and scheduled urine testing and the utilization of "validated drug detection technologies as they become available." Importantly, the guidance places an emphasis on objective results, with self-reported data being secondary.

Furthermore, the proposal delves into study duration, with the FDA recommending a duration of six months for OUD device trials. The guidance also addresses key areas of concern, like participant retention and data reduction. The FDA's focus extends to clinical outcome metrics, where drug usage patterns take center stage as both primary and secondary endpoints for evaluation.

In line with its continuous efforts to combat the opioid crisis, the FDA has not only recognized the need for innovative medical devices but also taken proactive measures to ensure the robustness of clinical trials supporting these devices. By addressing the challenges of OUD trials head-on and providing clear guidance to industry stakeholders, the FDA aims to foster the development of medical devices that can make a significant impact on the lives of individuals struggling with opioid addiction.

As the draft guidance undergoes a public comment period until October 26th, the medtech industry and other stakeholders have an opportunity to contribute their insights and suggestions. This collaborative approach is expected to refine the guidance further and drive the development of more effective medical devices to combat the opioid crisis.
