BridgeBio Pharma Inc. jumped in premarket trading after its drug got US regulators’ nod to treat a deadly form of heart disease, paving the way for head-to-head competition with medications from Pfizer Inc.

The U.S. Food and Drug Administration has approved BridgeBio's drug for a rare and deadly heart condition, the company said on Friday, making it the first new treatment in a market dominated by Pfizer's blockbuster Vyndaqel.

BridgeBio shares climbed by nearly 25% Monday on news its drug for a cardiac form of transthyretin amyloidosis was approved with a broad label that looks competitive to Pfizer's tafamidis.
