Grain-of-Rice device could end guesswork in skin treatment
NCT ID NCT07352566
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a tiny microdevice, about the size of a grain of rice, that holds up to 20 different FDA-approved skin medications. Placed directly on the skin, it releases very small amounts of each drug to see how the skin reacts. The goal is to find out if this device can safely predict which treatment will work best for a person with psoriasis or atopic dermatitis. Only 10 adults will take part, and the focus is on safety and whether the device can collect enough tissue for analysis.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- in situ cutaneous microdevice
- What this could lead to
- If successful, this microdevice could help doctors quickly identify which medication works best for a person's skin condition, saving time and trial-and-error.
- What could go wrong
- This is a very small early-stage study (10 people) focused on safety and feasibility, not on proving treatment effectiveness. The device may not reliably predict real-world responses.
