Opportunity Summary:

The grant opportunity titled "Clinical Development of Minimally-Invasive Bioassays to Support Outpatient Clinical Trials of Therapeutics for Substance Use Disorders (R21)" (Funding Opportunity Number PA-16-075) is a discretionary federal grant program offered by the U.S. Department of Health and Human Services through the National Institutes of Health (listed as HHS-NIH11). It was posted and created on January 8, 2016, with an application closing date of September 7, 2018. The opportunity uses the NIH R21 mechanism, which is commonly intended for exploratory and developmental research projects that are earlier-stage, higher-risk, or aimed at proving feasibility and generating the kind of preliminary evidence that can support a later, larger clinical or translational effort.

The core purpose of the FOA is to stimulate the development and clinical testing of minimally invasive or non-invasive bioassays that can strengthen outpatient clinical trials of medications intended to treat Substance Use Disorders (SUDs). In practical terms, the program is focused on measurement tools and biological assays that can be used in real-world outpatient settings, where frequent clinic visits, invasive sampling, or complex laboratory procedures can be difficult to implement and can reduce participant retention and data quality. By encouraging easier, lower-burden assessment methods, the FOA is aiming to improve how researchers monitor drug exposure, treatment adherence, substance use, relapse, and other clinically meaningful indicators during outpatient pharmacotherapy trials for SUDs.

Because the announcement explicitly emphasizes "clinical development" of these assays, the intent is not just basic biomarker discovery, but work that moves an assay toward usability in clinical trial contexts. That generally implies attention to factors like feasibility in outpatient workflows, acceptability to participants, reliability and repeatability, and the ability to produce interpretable results under real trial conditions. The emphasis on minimally invasive approaches suggests examples such as saliva-based testing, breath-based measures, sweat or transdermal monitoring, urine alternatives that reduce collection burden, or other approaches that avoid venipuncture or frequent in-person procedures. The FOA description highlights non-invasive methods broadly, leaving room for a range of technical approaches as long as they are designed to support outpatient clinical trials of SUD therapeutics.

Eligibility for this grant is broad and includes many types of organizations that commonly participate in NIH-funded research. Eligible applicants include state, county, and local governments; special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments and other tribal organizations; public housing authorities and Indian housing authorities; nonprofit organizations with and without 501(c)(3) status; for-profit organizations other than small businesses; and small businesses. The listing also notes an "Others" category with additional eligibility details referenced elsewhere in the full announcement, which is typical of NIH postings that allow a wide range of domestic research-performing entities to apply as long as they meet NIH policy requirements.

From an administrative standpoint, the opportunity is categorized under Education and Health funding activity and is associated with CFDA numbers 93.279 (and also referenced as 93.279 in the listing). The posted summary does not provide an award ceiling or an expected number of awards, which usually means applicants need to consult the full FOA text and NIH institute funding policies to understand typical budget limits and award patterns for R21s under the relevant institutes. Even without those figures in the summary, the R21 mechanism itself signals a smaller, time-limited project designed to generate strong proof-of-concept data rather than to fund a full-scale clinical trial.

Overall, this FOA is best understood as a targeted call for practical, patient-friendly biological measurement tools that make outpatient medication trials for substance use disorders more workable and more informative. The emphasis is on reducing invasiveness and logistical burden while improving the ability of researchers to capture objective, clinically relevant data in outpatient settings where most SUD care and many SUD trials are conducted.
