Heart medications Vyndaqel and Vyndamax generated $1.3 billion of global revenue last year for Pfizer and already brought in $453 million in the first quarter of this year.

Why it matters: The blockbuster drugs could grow significantly more if Pfizer wins its pending lawsuit and is allowed to pay the out-of-pocket expenses of Medicare patients who are prescribed the $225,000-a-year treatment.

Between the lines: The drugs, which both have the active ingredient tafamidis, have a complex history.

  • Pfizer didn't develop the drug. It acquired the drug's developer, FoldRx Pharmaceuticals, in 2010 for an undisclosed amount.

  • Pfizer then got the drug through a pivotal phase 3 trial and won FDA approval in 2019 after the FDA originally rejected the drug in 2012.

  • The National Institutes of Health funded the basic research that led to tafamidis.

  • Researchers say an annual price of $16,500, or a 93% discount, would match the drug's benefits. The United Kingdom won't cover tafamidis due in large part to the price. Pfizer does not disclose the drug's net price after rebates.
