## Summary

The Wellcome Infectious Disease Clinical Trial Award: Optimising Interventions Impact funds large-scale clinical trials testing new treatments for infectious diseases, with grants ranging from £1-8 million over 3-5 years. The award is open to research teams (at least one co-applicant required) based at eligible institutions worldwide who can design and execute rigorous intervention trials. This is a one-off call focused on translational research with near-term clinical potential.

## Who should apply

- Research teams with at least one co-applicant (consortium required)
- Clinical trial specialists with design and regulatory trial management experience
- Researchers at institutions with infectious disease clinical trial infrastructure
- Projects targeting novel or optimised interventions (drugs, vaccines, devices) for infectious diseases
- Teams with identified clinical partner sites and populations ready for trial recruitment

## Key dates

- This is a one-off call; verify exact deadline on Wellcome's grants portal
- Single-stage application and review
- Project duration 3-5 years

## Tips for applicants

- Consortium is non-negotiable, identify co-applicants early; weak or misaligned teams score poorly.
- Wellcome prioritises trials with realistic recruitment timelines; include preliminary feasibility data (site agreements, population estimates, logistical proof-points).
- Intervention novelty or optimisation must be articulated clearly; incremental tweaks to standard-of-care trials are less competitive.
