NIH Highlighted Topic: Understanding the Impact of Immune Function on Neurocognition and Substance Use Disorder Risk Across the Lifespan (IMMUNE-LIFESPAN)
Below is a brief summary. Please check the full solicitation before applying (link in resources section).
Executive Summary:
The National Institutes of Health (NIH) is seeking innovative research proposals through the SBIR Program focused on understanding how immune system function influences neurocognition, neuroinflammation, and substance use disorder (SUD) risk across the lifespan. NIH is particularly interested in technologies, computational models, and translational research approaches that investigate the dynamic relationship between immune dysregulation, neural function, behavioral responses, and addiction vulnerability.
Emerging evidence demonstrates that the immune system and nervous system are deeply interconnected, influencing cognition, neural circuitry, stress responses, and behavioral outcomes through complex molecular and cellular mechanisms. Many environmental, developmental, and psychosocial risk factors associated with SUD—including chronic stress, substance exposure, infection, maternal health, and aging—also affect immune system function. NIH is encouraging projects that advance systems-level understanding of neuroimmune interactions and their role in addiction development, progression, relapse, and recovery.
Companies developing neuroimmune analytics platforms, AI-enabled computational models, biomarker technologies, neuroinflammation diagnostics, imaging systems, precision medicine tools, behavioral health technologies, or translational neuroscience platforms may be strong candidates for funding. NIH is especially interested in projects examining molecular, cellular, circuit-level, and lifespan mechanisms connecting immune dysregulation and SUD-related cognition and behavior.
Through the NIH SBIR Program, U.S. small businesses may apply for up to $323,090 in Phase I funding and up to $2,153,927 in Phase II funding to support research, development, validation, and commercialization activities. Applications are accepted on January 5th, April 5th, and September 5th annually, with funding typically beginning approximately 9 months after submission.
This highlighted topic is supported primarily by the National Institute on Drug Abuse (NIDA), the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the Office of Research on Women’s Health (ORWH), all of which may give special consideration to high-impact applications advancing neuroimmune science, addiction neuroscience, biomarker discovery, computational behavioral health, and precision intervention technologies.
How much funding would I receive?
Awards provide up to $323,090 for Phase I projects (up to 2 years) and $2,153,927 for Phase II projects (up to 3 years). Some topics approved by NIH may exceed these limits. Fast-Track and Phase IIB (follow-on) options allow continuous or extended funding beyond Phase II.
What could I use the funding for?
Funding may support the research, development, validation, and commercialization of technologies and therapeutic approaches focused on addiction neuroscience, sensory integration, and substance use disorder mechanisms.
Eligible activities may include:
Development of neurotechnology platforms for studying reward circuitry and sensory processing
AI and machine learning tools analyzing addiction-related neural activity and behavioral patterns
Neuromodulation technologies targeting sensory-reward neural pathways
Computational neuroscience models evaluating subjective reward processing and addiction progression
Imaging technologies for studying interoception, sensory integration, and synaptic plasticity
Behavioral assessment platforms measuring sensory-evoked responses and motivated behavior
Research investigating neural adaptations associated with acute, chronic, and withdrawal-related drug exposure
Technologies exploring multisensory influences on substance use and relapse vulnerability
Genetic and molecular studies identifying enhancers or suppressors of reward and sensory systems
Precision medicine and personalized intervention approaches for substance use disorders
Sex-specific neuroscience research examining addiction-related neural processing differences
Drug discovery and therapeutic development targeting sensory-reward neural circuits
Digital health tools supporting addiction monitoring, behavioral intervention, and recovery management
Validation studies, translational research, prototype development, and regulatory preparation activities
Commercialization planning and scale-up activities for neuroscience, neurotechnology, and addiction treatment solutions
Funding may also support personnel, laboratory testing, software development, computational infrastructure, prototype fabrication, neuroimaging systems, intellectual property protection, commercialization strategy development, and other research and development activities necessary to advance a commercially viable solution aligned with NIH priorities.
Are there any additional benefits I would receive?
Beyond the formal funding award, awardees gain several strategic advantages:
Government Validation and Credibility:
Being selected for an NIH-backed SBIR grant signals technical excellence and alignment with national health and biomedical priorities. This validation builds investor and partner confidence.Enhanced Visibility and Market Recognition:
Awardees are featured in NIH and HHS announcements, helping attract partnerships, media attention, and future contracting opportunities.Access to the Federal Innovation Ecosystem:
Recipients join a national network of researchers and agencies advancing life science innovation, often opening doors to collaborations with NIH laboratories and federal health programs.Stronger Commercial and Exit Potential:
By maturing technology through nondilutive funding, companies strengthen valuation, de-risk commercialization, and increase attractiveness for acquisition or follow-on private investment.
What is the timeline to apply and when would I receive funding?
Applications are accepted each year on January 5th, April 5th, and September 5th. Funding is received approximately 9 months after submission.
Where does this funding come from?
Funding comes from the U.S. Department of Health and Human Services, with statutory set-asides requiring NIH, CDC, and FDA to devote portions of their extramural R&D budgets (3.2% for SBIR, 0.45% for STTR) to support small business innovation.
Who is eligible to apply?
Applicants must be U.S. small business concerns (SBCs) that:
Are organized for profit with a U.S. place of business.
Have ≤ 500 employees including affiliates.
Are > 50% owned by U.S. citizens or permanent residents, qualifying U.S. entities, or combinations thereof.
What companies and projects are likely to win?
Projects that demonstrate:
A clear unmet medical or public-health need,
Strong scientific rationale and feasibility,
High commercialization potential, supported by a realistic market and regulatory strategy, and
Alignment with an NIH Institute’s or CDC/FDA Center’s specific research mission (e.g., infectious disease, digital health, diagnostics, therapeutics, or data analytics).
Competitive applicants often have an early prototype, preliminary data, and a defined path to market adoption.
Are there any restrictions I should know about?
Companies must complete multiple federal registrations (SAM.gov, Grants.gov, eRA Commons, SBA Company Registry) before applying.
Foreign entities are not eligible.
Disclosure of foreign affiliations and compliance with national security screening are mandatory. Currently we do not recommend any sort of foreign affiliation.
How long will it take me to prepare an application?
For a first-time applicant, preparing a competitive submission will likely take 120–200 hours in total.
