In a promising small trial, a new stem cell-based drug called zimislecel appears to have cured 10 out of 12 participants with severe type 1 diabetes—freeing them from insulin dependence. However, the treatment may not be effective for those with milder forms of the disease.

Editor’s Note: This could be a game-changer for people with the most aggressive cases of type 1 diabetes, offering hope where treatments have been limited. But don’t cancel your insulin prescriptions just yet—it’s still early days, and the therapy might not help everyone. Still, it’s a big leap toward potentially curing what was once considered a lifelong condition.
