CFPs: Novel Interventions Targeting Placental and Gut Inflammation to Improve Fetal Growth

Deadline: 28-Apr-2026

The Gates Foundation invites proposals for innovative interventions targeting placental and gut inflammation and oxidative stress to improve fetal growth outcomes. Projects can span mechanism discovery, candidate validation, and early clinical proof-of-concept, with funding up to $1,000,000 depending on the track. The challenge prioritizes scalable, mechanistic interventions in high-burden regions like sub-Saharan Africa and South Asia.

Overview of the Opportunity

The Gates Foundation seeks proposals for novel interventions aimed at mitigating placental and gut inflammation and oxidative stress to improve fetal growth and prevent fetal growth restriction (FGR), also known as intrauterine growth restriction. FGR is a major contributor to stillbirth, neonatal mortality, and long-term morbidity, particularly in sub-Saharan Africa and South Asia. The initiative emphasizes mechanistic research and interventions with translational or early clinical potential.

Focus Areas and Tracks

1. Track 1: Mechanism and Target Discovery

   • Investigate maternal gut-placenta inflammatory or oxidative stress pathways.

   • Validate at least one target or pathway.

   • Nominate actionable intervention strategies.

   • Funding: Up to $400,000 for 18 months.

2. Track 2: Candidate Validation and Translational Advancement

   • Advance a defined intervention candidate with mechanistic rationale.

   • Provide biomarker-linked evidence of biological activity.

   • Conduct translational validation studies.

   • Funding: Up to $750,000 for 24 months.

3. Track 3: Early Clinical Proof-of-Concept

   • Conduct early human studies of advanced or repurposed candidates.

   • Emphasize safety, feasibility, biological activity, and biomarker modulation.

   • Funding: Up to $1,000,000 for 30 months.

Scientific Rationale

Placental dysfunction is central to FGR, often involving impaired vascularization, altered nutrient transport, and dysregulated immune signaling. Emerging evidence suggests gut-placenta inflammatory axes may influence placental function, fetal metabolism, and growth. Proposed interventions should target these mechanistic pathways, with clear hypotheses supported by existing evidence and defined go/no-go criteria. Purely observational studies or nutritional interventions not addressing inflammation or oxidative stress are excluded.

Who Should Apply?

Eligible applicants include:

• Nonprofit organizations

• For-profit companies

• Academic and research institutions

• International organizations and consortia
  Collaboration with institutions in the global south is strongly encouraged. Individuals or entities classified as individuals for U.S. tax purposes are not eligible.

Proposal Requirements

• Clearly define pathways linking inflammation or oxidative stress to placental and gut function.

• Include quantitative success criteria, timelines, and deliverables.

• Demonstrate feasibility within the proposed budget and award period.

• Provide a clear plan for generating preliminary data to guide future investment.

• Multidisciplinary expertise in immunology, obstetrics, pharmacology, translational biology, or related fields is encouraged.

Funding Considerations

• Track-specific budgets must align with proposed deliverables.

• Indirect costs should comply with standard institutional policies.

• Exclusions include commercial nutritional supplements without mechanistic evidence, antibiotics or antimicrobials contributing to resistance, and drugs or bioactive compounds contraindicated in pregnancy or lactation.

Expected Outcomes

• Validation of novel mechanistic targets or pathways.

• Translational advancement of intervention candidates.

• Early clinical proof-of-concept for interventions addressing placental or gut inflammation.

• Data supporting scalable strategies to reduce FGR in high-burden settings.

Why This Opportunity Matters

• Addresses a critical global health challenge affecting neonatal survival and long-term child health.

• Promotes interventions that are mechanistically grounded and potentially scalable in resource-limited settings.

• Supports multidisciplinary collaboration and innovation in maternal-fetal health.

• Provides actionable data to inform future investments in FGR prevention and intervention strategies.

How to Apply

1. Identify a track that aligns with your research stage and capabilities.

2. Develop mechanistic hypotheses and intervention strategies.

3. Use existing experimental platforms or human datasets and biobanks where possible.

4. Define quantitative success criteria and timelines.

5. Prepare a detailed budget and justify expenditures in relation to deliverables.

6. Submit through the Gates Foundation’s application portal by the stated deadline.

Common Mistakes to Avoid

• Submitting observational studies without an intervention.

• Proposing interventions requiring highly specialized infrastructure unlikely to be scalable.

• Ignoring mechanistic relevance of nutritional interventions.

• Using drugs or supplements contraindicated during pregnancy or lactation.

• Failing to collaborate with institutions in high-burden regions for contextual relevance.
