Resamirigene bilparvovec

Resamirigene bilparvovec (codename: AT132) is an experimental gene therapy medication studied as a treatment for X-linked myotubular myopathy (XLMTM), a severe and usually fatal genetic disorder affecting mainly male infants and caused by a mutation in the MTM1 gene. The drug consists of a MTM1 transgene encapsulated in a viral vector from the adeno-associated virus class (AAV8) and is administered to affected children as an intravenous infusion.
