The research team identified two classes of drugs that turn off DUX4. The first are a class of drugs that inhibit bromodomain and extra-terminal (BET) proteins and the second are drugs that turn on beta-2 adrenergic signaling (beta agonists). These classes of drugs already are being studied and utilized for other illnesses; BET inhibitors currently are being studied in clinical trials for cancer and other diseases while beta agonists are widely used for asthma and chronic obstructive pulmonary disease.
