First seen Jan 05, 2026 · Last updated May 17, 2026 · Updated 22 times

Summary

This study tested an experimental mRNA medicine called mRNA-3705 in 18 people with a rare genetic condition called methylmalonic acidemia (MMA), which causes harmful acid buildup in the body. The goal was to see if the treatment is safe and can lower MMA levels. The study was terminated early, so results are limited.
