Could a nerve channel blocker replace opioids? early study investigates

NCT ID NCT07511400

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a drug called suzetrigine, which blocks a specific nerve channel (NaV1.8) involved in pain signaling. In 67 healthy volunteers, tiny amounts were injected into the skin alongside a placebo and lidocaine. Participants received six different types of brief pain (electrical, mechanical, chemical, heat, cold, acid) to see which ones the drug could reduce. The goal is to understand which pain types depend on NaV1.8, potentially guiding development of new, non-opioid pain treatments.

What this could mean

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

Active substance

Suzetrigine (a selective NaV1.8 blocker) and lidocaine (a standard local anesthetic)

What this could lead to

If successful, this study could help identify which types of pain are best treated by targeting NaV1.8, paving the way for new non-opioid pain medications.

What could go wrong

This is a very early, small study in healthy volunteers using tiny doses injected into the skin. Results may not apply to real-world pain or lead directly to a new drug.
