New CF drug cocktail enters first human safety tests

NCT ID NCT07035990

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This early-stage trial tests the safety of three experimental drugs (SION-451, SION-2222, and SION-109) given together to healthy adults aged 18–55. The study aims to see if the combinations are safe and how the body processes them. It is a first step toward possibly developing a better treatment for cystic fibrosis, but does not yet involve people with the disease.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

SION-451, SION-2222, and SION-109 (oral drugs)

What this could lead to

If safe, this could lead to a new combination therapy for cystic fibrosis that helps control the disease more effectively.

What could go wrong

This is a very early Phase 1 trial in healthy people, not patients. It only checks safety and drug levels, not whether it works for CF. Many early drugs fail in later stages.
