How is Exondys 51 dosing converted into an annual cost?
Exondys 51 is dosed by body weight, so the annual cost is driven by:
- Patient weight (heavier patients generally require more drug per dose).
- The prescribed weekly dosing schedule.
- The drug’s per-vial/pack cost at the time it’s dispensed.
Because dosing is weight-based, two patients can have materially different annual totals even under the same treatment plan.

Common reasons include:
- Using list price vs. net price after rebates.
- Different assumptions about dose units, vial size, and wastage.
