## Summary

Erdera funds transnational research consortium projects on rare diseases, with the Swiss partner(s) supported directly by SNSF. The call requires a minimum of three entities across three EU member states, plus Swiss participation, and applies standard SNSF Project funding criteria. Consortia are expected to address unmet needs in rare disease research through collaborative, cross-border investigation.

- Experienced researchers meeting standard SNSF Project funding criteria

## Key dates

- Deadline varies by call cycle (verify on SNSF Erdera portal)
- Annual call frequency
- Consortium of minimum 3 entities from 3 EU member states required

## Tips for applicants

- The consortium structure is gating, a weak or poorly-coordinated partner group will harm even strong science; invest in alignment before submission.
- SNSF funds only the Swiss partner(s); clarify with each non-Swiss partner how they will secure national funding before committing them to the proposal.
- Rare disease focus must be genuine; SNSF panels distinguish between opportunistic rare-disease framing and substantive unmet-need research.
