Hope for untreatable muscle disease: transplant drug shows promise

This study tested whether rapamycin, a drug used in organ transplants, could help stabilize muscle strength in adults with inclusion body myositis—a progressive muscle disease that currently has no effective treatment. Forty-four participants were randomly assigned to receive either rapamycin or a placebo to see if the drug could slow the decline in leg strength. Researchers measured walking ability, hand grip strength, and quality of life to determine if rapamycin offered benefits for this difficult-to-treat condition.
