About Phathom Pharmaceuticals

Phathom helps people with painful stomach acid and infections. Its main medicine blocks acid production better than older drugs. These products treat heartburn and bacteria that cause ulcers.

The Medicine Cabinet

  • VOQUEZNA Tablets: Oral medicine used to treat and manage acid reflux disease in adults.
  • VOQUEZNA DUAL PAK: Combination of two medications used to clear stomach bacteria called H. pylori.
  • VOQUEZNA TRIPLE PAK: Three-drug bundle containing an acid blocker and two antibiotics; accounted for about 1% of revenue in 2025.

Major Moves and Milestones

  • In 2019, the company licensed the rights to its primary drug from Takeda Pharmaceutical Company Limited.
  • Launched its first commercial products in the United States during the fourth quarter of 2023.
  • Successfully requested that the FDA extend the marketing exclusivity for its core treatment until 2032.
  • Started a Phase 2 clinical trial for a new stomach tissue condition in late 2025.

What Makes Phathom Different?

Phathom sells the only potassium-competitive acid blocker approved in the United States. This drug class represents the first major innovation in stomach acid treatment in over 30 years.

Profitability and Sales Metrics

  • Revenue rose to $58.3 million in Q1 2026, up 104.4% year-over-year.
  • Gross profit reached $46.3 million in Q1 2026, up 86.8% from Q1 2025.
