I don't think they can get around it that easily because both the patent protections and the FDA approval are based on the "active ingredient" and delivery method and thus they cannot easily introduce a new variant without going to a lot of expense.

But they already have to get their drugs certified independently in other countries so yes it costs more to introduce multiple varients to the US market but it does not cost much more to introduce different varients to multiple countries that require independent verification of the drugs anyways.
