Opportunity Summary:

The NIH Countermeasures Against Chemical Threats (CounterACT) program is focused on building medical treatments that can prevent or reduce injury after exposure to dangerous chemicals. These chemical threats include both classic chemical warfare agents and toxic industrial chemicals that might be deliberately released during an attack or accidentally released during manufacturing, storage, or transportation. The goal of this particular opportunity is not basic discovery, but practical development work that moves a promising therapy closer to real-world use.

This funding opportunity, titled "Countermeasures Against Chemical Threats (CounterACT): Optimization of Therapeutic Lead Compounds (U01)" (PAR-16-128), supports projects that already have a lead therapeutic candidate and are ready to optimize it for development. To be eligible, applicants must start with a previously identified lead compound, either a small molecule or a biologic. In this context, a lead compound is not just an early screening hit; it is something with demonstrated biological activity where key fundamentals have already been established, including affinity, potency, target selectivity, and at least preliminary safety. In other words, the FOA is aimed at teams that have cleared the earliest scientific hurdles and are prepared to do the translational work needed to make the candidate more development-ready.

The activities supported under this FOA cover a set of mid-stage translational tasks commonly needed before a therapy can advance toward formal regulated development. A major emphasis is on generating in vivo evidence that matches how the product is intended to be used in people, which often requires building or refining animal models that are as human-relevant as possible for the chemical injury being addressed. Alongside efficacy work, the FOA also supports the kind of enabling infrastructure that therapeutic development depends on, such as development and validation of bioanalytical assays to measure the drug and relevant biomarkers. It further includes laboratory-scale manufacturing and scale-up efforts, recognizing that many promising leads fail when they cannot be produced consistently, at sufficient purity, or in forms suitable for dosing and testing.

Non-GLP toxicology and pharmacology studies are also within scope. These studies are meant to inform safety and dosing decisions and to identify potential liabilities early, even if they are not yet the formal GLP studies typically required for regulatory submissions. Overall, the FOA is framed around Technical Readiness Levels (TRLs) 4-5, meaning the work is expected to be beyond proof-of-concept and focused on validation and optimization in relevant systems, with increasing rigor and a clear line of sight toward later-stage development.

The award mechanism is a U01 cooperative agreement, which generally means NIH anticipates active involvement with the project beyond standard grant oversight. A defining requirement in this announcement is the use of annual milestones that function as clear go/no-go decision points. Applicants are expected to lay out a progressive translational plan where each year produces concrete deliverables that demonstrate whether the candidate is advancing appropriately or whether the project should be redirected or stopped. This milestone-driven structure is intended to keep projects focused on measurable development progress rather than open-ended research.

From an eligibility standpoint, the FOA is broadly open to many types of organizations, including federal-recognized tribal governments and tribal organizations, state and local governments, public and private universities, nonprofit organizations (with or without 501(c)(3) status), for-profit organizations (including small businesses), and other entities as described in the full eligibility language. The opportunity is offered by HHS/NIH (listed as HHS-NIH11) under CFDA numbers 93.113, 93.846, 93.853, and 93.867. The original and current closing date listed in the source data is September 11, 2018, and the posting and creation date is March 10, 2016.

In practical terms, this FOA is meant for groups that can show they already have a credible therapeutic lead against a defined chemical threat and can execute the next development steps: optimizing the candidate, proving efficacy in relevant animal models, building the assays and manufacturing capabilities to support further testing, and collecting early safety and pharmacology data. The milestone and TRL framing signals that NIH is looking for disciplined, development-oriented projects that can make objective progress toward a usable medical countermeasure.

No. The stated goal is not basic discovery. It is aimed at translational, mid-stage development work that advances a promising therapy toward being development-ready for real-world application.

What kinds of chemical threats are covered?

The scope includes classic chemical warfare agents and toxic industrial chemicals. These may involve deliberate releases during an attack or accidental releases during manufacturing, storage, or transportation.

What stage of development should a project be in to fit this FOA?

The FOA is framed around Technical Readiness Levels (TRLs) 4-5. This generally means the work should be beyond proof-of-concept and focused on validation and optimization in relevant systems with increasing rigor and a clear path toward later-stage development.

Do applicants need to already have a lead therapeutic candidate?

Yes. Projects must start with a previously identified lead therapeutic candidate that is ready for optimization for development.

What types of lead candidates are eligible?

The lead candidate may be a small molecule or a biologic, as long as it meets the FOA's expectations for a true lead compound (not merely an early screening hit).

How does the FOA define a "lead compound" for eligibility purposes?

In this FOA, a lead compound is not an early screening hit. It must have demonstrated biological activity and have key fundamentals already established, including affinity, potency, target selectivity, and at least preliminary safety.

What are the main activities and project types supported?

The FOA supports mid-stage translational tasks needed to move a therapy toward formal development. Examples described include generating in vivo evidence aligned with intended human use, developing or refining human-relevant animal models for the chemical injury, developing and validating bioanalytical assays (including biomarkers), laboratory-scale manufacturing and scale-up, and non-GLP toxicology and pharmacology studies.

Is in vivo efficacy work part of the expected scope?

Yes. A major emphasis is on generating in vivo evidence that matches the intended use in people, which can include building or refining animal models that are as human-relevant as possible for the injury being addressed.
