Opportunity Summary:

The Sustained Release of Antivirals for Treatment or Prevention of HIV (SRATP) (R01) funding opportunity (PAR-16-262) is a discretionary NIH research grant announcement focused on advancing longer-acting drug delivery approaches for HIV. Its central goal is to stimulate research and development that can move HIV therapeutics and prevention products beyond daily or very frequent dosing by using sustained-release strategies. The underlying aim is improved durability of drug levels, which can support more consistent protection or viral suppression and potentially reduce the adherence burden that often limits real-world effectiveness.

This FOA invites applications proposing sustained-release antiviral products for either HIV treatment or HIV prevention, and it explicitly allows multiple delivery routes and technology platforms. Proposed approaches can include oral sustained-release formulations, long-acting injections, implants, or direct delivery systems designed for HIV target mucosal tissues. The opportunity is structured around minimum duration expectations tied to the delivery method: oral sustained-release strategies for treatment are expected to provide at least one week of coverage, while non-oral sustained-release systems (such as injections, implants, or mucosal delivery approaches) are expected to provide at least monthly dosing for either prevention or treatment, meaning the system should maintain protective or therapeutic efficacy with dosing no more frequent than once per month.

The award mechanism is an NIH R01, indicating support for substantial, hypothesis-driven or product-oriented research projects with clear aims and a defined development path. While the announcement summary does not list an award ceiling or the expected number of awards, the R01 mechanism generally supports multi-year research programs and can accommodate interdisciplinary teams, which is often important for sustained-release antivirals that sit at the intersection of pharmacology, formulation science, biomedical engineering, materials science, and HIV clinical/preclinical research.

Eligibility is broad and includes many organization types that commonly participate in biomedical product development. 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/Indian housing authorities; nonprofit organizations with or without 501(c)(3) status (excluding institutions of higher education in those specific nonprofit categories); for-profit organizations (including entities other than small businesses); small businesses; and additional applicants as clarified in the full announcement text. This breadth signals an intent to attract proposals from academic labs, research institutes, product developers, and collaborative academic-industry teams.

Administratively, the opportunity is sponsored by HHS through the NIH (listed as HHS-NIH11) and is associated with CFDA numbers 93.242, 93.855, and 93.856, reflecting NIH program areas relevant to infectious disease, biomedical research, and HIV/AIDS-related work. The FOA was created and posted on May 17, 2016, and the listed closing date for the opportunity was January 4, 2019. Overall, the announcement is geared toward building and validating sustained-release antiviral delivery systems capable of providing week-long oral treatment coverage or month-or-longer protection/efficacy for other delivery modalities, with the broader public health aim of strengthening HIV treatment and prevention options through longer-acting formulations.

FAQs: Sustained Release of Antivirals for Treatment or Prevention of HIV (SRATP) (R01) (PAR-16-262)

What is the SRATP (R01) funding opportunity (PAR-16-262)?

SRATP (R01) (PAR-16-262) is a discretionary NIH research grant opportunity focused on advancing sustained-release (longer-acting) drug delivery approaches for HIV treatment and HIV prevention.

What is the main goal of this FOA?

The central goal is to stimulate research and development of longer-acting antiviral delivery strategies that move HIV therapeutics and prevention products beyond daily or very frequent dosing by maintaining durable drug levels over time.

Why is NIH emphasizing sustained-release antivirals for HIV?

The FOA is aimed at improving the durability of drug levels to support more consistent protection or viral suppression and to reduce the adherence burden that can limit real-world effectiveness of HIV treatment and prevention.

Does this opportunity support HIV treatment, HIV prevention, or both?

Both. The FOA invites applications proposing sustained-release antiviral products for either HIV treatment or HIV prevention.

What types of drug delivery approaches are allowed?

The announcement explicitly allows multiple delivery routes and technology platforms. Examples mentioned include oral sustained-release formulations, long-acting injections, implants, and direct delivery systems designed for HIV target mucosal tissues.

Are oral sustained-release approaches allowed?

Yes. Oral sustained-release strategies are specifically included as an allowable approach.

Are long-acting injections and implants allowed?

Yes. Non-oral sustained-release systems such as injections and implants are explicitly listed as allowable approaches.

Does the FOA allow direct delivery to mucosal tissues?

Yes. The FOA includes direct delivery systems designed for HIV target mucosal tissues among the allowable approaches.

What minimum duration is expected for oral sustained-release strategies?

For oral sustained-release strategies intended for HIV treatment, the expectation is at least one week of coverage.

What minimum duration is expected for non-oral sustained-release systems?

For non-oral sustained-release systems (for example, injections, implants, or mucosal delivery approaches), the expectation is at least monthly dosing for either prevention or treatment, meaning dosing should be no more frequent than once per month while maintaining protective or therapeutic efficacy.

Does the monthly dosing expectation apply to both prevention and treatment?

Yes. The minimum expectation described for non-oral sustained-release systems is at least monthly dosing for either HIV prevention or HIV treatment.

What is the funding mechanism for SRATP?

The award mechanism is an NIH R01 research project grant.

What does using an R01 mechanism imply about the project type?

The R01 mechanism indicates support for substantial research projects with clear aims and a defined development path, and it can support hypothesis-driven or product-oriented work.
