Request for Information (RFI): Data Informatics Needs and Challenges for Enabling SPARC (Stimulating Peripheral Activity to Relieve Conditions)
Notice Number: NOT-RM-15-010
Release Date: April 2, 2015
Response Date: April 30, 2015
Office of Strategic Coordination (Common Fund)
The National Institutes of Health (NIH) is seeking input on SPARC-relevant data. SPARC (Stimulating Peripheral Activity to Relieve Conditions) (http://commonfund.nih.gov/sparc/index) is a new program to deliver detailed, integrated functional and anatomical neural circuit maps in multiple organ systems. These maps will be directly leveraged to develop and pilot novel electrode designs, with corresponding stimulation protocols and minimally invasive surgical procedures, to improve existing neuromodulation therapies or pursue new indications. SPARC will provide the scientific foundation required to catalyze the development of new and/or more efficacious therapies utilizing closed-loop neuromodulation to modulate end-organ system function. This will be accomplished primarily by generating detailed functional maps of end-organ systems in appropriate animal models, while validating the relevance of these maps for human translation. The NIH is interested in understanding how cellular and tissue based responses form the underlying mechanisms of neural control networks. SPARC is primarily focused on autonomic nervous system control of, and sensory feedback from, internal organs, but interests may extend beyond these to other organs that show promise for development of neuromodulation therapies.
Pending the availability of funds, SPARC is being implemented in FY 2015 by the NIH Common Fund which supports cross-cutting programs that are expected to have exceptionally high impact. The SPARC program is a high-risk, goal-driven endeavor to provide insights into the neural control of organ function, and lay the foundation for development of neural control devices to precisely treat a wide variety of diseases and conditions.
NIH seeks input from the biomedical research community, potential biotechnology and pharmaceutical company partners, and other members of the public on this new program. Through the SPARC program, the NIH tentatively plans to support interdisciplinary teams of investigators to deliver neural circuit maps of several organ systems, novel electrode designs, minimally invasive surgical procedures, and stimulation protocols. Driven by end goals of improving existing and developing new neuromodulation therapies, the program will be iterative and dynamic, with the novel technologies informing mapping efforts, and the mapping results defining new technology requirements.
Current plans for SPARC include potential initiatives to:
- Deliver detailed, integrated functional/anatomical neural circuit maps in multiple organs or organ systems for understanding the underlying mechanisms of control; develop/pilot novel electrode designs, surgical procedures, and stimulation protocols leveraging insights from the functional maps (see NOT-RM-14-016 for details).
- Develop next-generation technology for stimulating and recording of visceral nerves and tissues, e.g., optogenetics, stimulating/recording electrodes, cell-type specific tracing (see NOT-RM-14-017 for details). The SPARC program is currently soliciting applications to develop new and/or enhance existing tools and technologies tailored to elucidate the neurobiology and neurophysiology underlying autonomic control of internal organs in health or disease, to inform next generation neuromodulation therapies (see RFA-RM-15-002 for details).
- Partner with industry and FDA to explore utility of existing, approved devices to address new, small-market indications (see NOT-RM-14-015 for details).
- Assemble data from all SPARC initiatives into a coordinated data resource, develop user-friendly computational tools, and incorporate new computer modeling methods (subject of this current RFI).
This RFI, in conjunction with the SPARC Strategic Planning: Biology & Technology Workshop held February 25 and 26, 2015, is intended to gather information and may lead to a subsequent funding opportunity announcement; however, this RFI should not be construed as a funding opportunity. Additional information, including current and future funding announcements for SPARC, can be found at: http://commonfund.nih.gov/sparc/index).
This RFI invites input from the scientific community, potential industry partners, and other members of the public on all aspects of the program.
