Guiding the Tide of Neurotechnology: Coordinating the Currents of Sea-Change



Recently, the Food and Drug Administration (FDA) solicited input to guide ways that the agency regards and handles “Clinical Considerations for Investigational Device Exemptions (IDEs) for Neurological Devices Targeting Disease Progression and Clinical Outcomes”, in accordance with good practices regulation (21 CFR 10.115). The FDA will use this draft guidance to “…assist sponsors who intend to submit an IDE to the FDA to conduct clinical trials on medical devices targeting neurological disease progression and clinically meaningful patient centered outcomes”, and “… aid industry and FDA staff in considering the benefits and risks of medical devices that target … the cause or progression of neurological disorders or conditions” (such as movement disorders, like Parkinson’s disease and dystonia; as well as other pathologies, like Alzheimer’s dementia, Tourette’s syndrome, chronic pain, and psychiatric conditions such as depression).

The goal of the FDA regulation process is to establish that drugs and devices provided for medical care are safe and technically sound and the general constructs of Investigational Device Exemption (IDE) and Humanitarian Device Exemption (HDE) are aligned with such aims. But like any policies that tend to entail broad concepts, the real-world utility, viability and value of these programs are contingent upon: (1) the relative appropriateness to the context(s) in which any device is employed; and (2) if and how use-in practice reflects and is supported by the scope of regulatory oversight and control.

In recent years, IDE and HDE application, review and approval has become easier and more efficient; this is a notable improvement – and a step in the right direction. However, it may be that aspects of the overall structure and certain specifics of the IDE and HDE are not well suited to meet the contingencies (and exigencies) of actual clinical use of certain neurotechnologies, like deep brain stimulation (DBS).   For example, the current regulatory framework necessitates filing and securing an IDE as a first step in investigator-initiated research (IIR) and/or other off-label use of DBS in those cases where other approaches have been shown to be ineffective or untenable, and for which DBS may prove to be viable as “humanitarian care”. In such instances, it may be that the proverbial cart precedes the horse, and the HDE might be more practical and valuable given both the nature of the disorder and treatment, and the value of the HDE in establishing a basis for further (and/or expanded) application, as supportable by an IDE.

Moreover, while both IDE and HDE establish parameters for using DBS in practice, neither regulatory mechanism creates or enforces a basis for provision of economic support necessary for right and good use-in-practice. As our recent work has demonstrated, non-payment of insurance costs for pre-certified DBS interventions has been, and remains a problem of considerable concern. Absent the resources to provide: 1) DBS as a demonstrably-important or necessary treatment option for those patients with conditions that are non-responsive to, or not candidate for other therapeutic options , and 2) continuity of clinical services as required, the sustainability of this neurotechnology may become questionable (Rossi, Okun, and Giordano, 2014). This is contrary and counter-productive to recent federal incentives to maximize benefits of translating extant and new neurotechnologies into clinically-relevant and affordable care, and to implementing precision medicine . This was the focus of much discussion at the fourth National Deep Brain Stimulation ThinkTank held last month in Gainesville, FL.

In the main, actions taken by the FDA to streamline the IDE and HDE process should be applauded. Yet, while certain aspects of the IDE and HDE mechanisms may be in order and valuable for regulating use of DBS, others may require re-examination, revision, or replacement, so as to remain apace with the rising tide of developments in the field, and needs and necessities of patients and clinicians in practice. In this vein, we recommend further study of IDE and HDE mechanisms to determine what works, what doesn’t, and what can – and should – be done to both improve these practices. It is our hope that doing this will fortify regulatory, policy and legal processes to ensure that they are aligned with, directive toward, and supportive of concomitant changes in standard of care guidelines and federal insurance structure.

Important to this endeavor would be both the development of a governmental-commercial enterprise to guide industrial efforts in neurotechnology (e.g.- a National Neurotechnology Initiative; NNTI), as well as the establishment and enactment of federal laws (e.g.- a neurological information non-discrimination act; NINA) to govern potential use(s) of information obtained through DBS and related neurotechnologies that are elements of novel big data initiatives. This might be something of a sea-change, and effecting such change will demand that the constituent currents flow in the same direction. If programs such as the BRAIN initiative and agendas of precision medicine and big data are to function as a “translational estate”, and work in ways that enable technically apt and ethically sound patient care, then what is needed is coordination of the institutions, organizations, resources and activities involved. Without doubt, this will entail considerable effort, which might make waves in the status quo; but we believe that it represents a worthwhile endeavor to achieve genuine and durable progress in the development and – right and good – use of neurotechnology in clinical practice.
