Old drug, new hope: DCA may shield brain from low blood sugar in type 1 diabetes

NCT ID NCT05317455

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase study tests whether dichloroacetate (DCA), a drug used safely for decades in a rare metabolic disorder, can improve brain function during low blood sugar (hypoglycemia) in people with type 1 diabetes. Sixteen participants with a history of severe hypoglycemia or hypoglycemia unawareness will receive DCA or a placebo in a crossover design. The goal is to see if DCA helps maintain cognitive function and brain glucose metabolism during controlled low blood sugar episodes.

What this could mean

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

Active substance

Dichloroacetate (DCA)

What this could lead to

If it works, this could point toward a way to protect brain function during low blood sugar episodes in people with type 1 diabetes.

What could go wrong

This is a very small, early-phase pilot study with only 16 participants, so results may not apply broadly. The drug's effect on brain function under hypoglycemia is still uncertain.
