KEY POINTS
  • President Donald Trump and Vice President Mike Pence had been major supporters of the "right-to-try" legislation, which would bypass drug regulators to give gravely ill patients access to experimental medicines.
  • Proponents say this gives patients hope they would not otherwise have.
  • Critics say the legislation undermines the FDA's authority to regulate drugs and could leave patients vulnerable to medicines that might not work or may even be harmful.

President Donald Trump signed the controversial "right-to-try" bill into law on Wednesday, which bypasses drug regulators to give gravely ill patients access to experimental medicines.

The legislation allows patients with life-threatening conditions to ask drugmakers for medicines that have cleared some testing but still haven't been approved by the Food and Drug Administration. Previously, patients would need to ask the FDA for access to experimental treatments.
