FLORHAM PARK, N.J, Nov. 03, 2026 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on commercializing and developing novel treatments for gastrointestinal diseases, today announced that eligible commercially insured patients may pay as little as $0 for VOQUEZNA^® (vonoprazan) tablets exclusively through BlinkRx, Phathom’s pharmacy network partner, subject to eligibility requirements, benefit limits, and program terms. The offer is part of Phathom’s broader efforts to make it easier and more affordable for patients with gastroesophageal reflux disease (GERD) to fill their VOQUEZNA prescriptions.

“We believe that patients with GERD who are prescribed VOQUEZNA should be able to start and stay on their medication, without unnecessary cost or paperwork getting in the way,” said Steve Basta, President and Chief Executive Officer of Phathom Pharmaceuticals. “By partnering with BlinkRx, we’re working to make VOQUEZNA easier and more affordable to access, with eligible commercially insured patients now having the potential to pay as little as $0, as well as continuing to offer a cash-pay option for those without insurance coverage. For many people living with GERD, finding the right treatment can be a long journey. Once their doctor prescribes VOQUEZNA, starting treatment should be the easy part. This initiative reflects our focus on putting patients first.”

How it works

• As little as $0: Commercially insured patients may pay as little as $0 for VOQUEZNA exclusively through BlinkRx, subject to eligibility requirements, benefit limits, and terms and conditions, whether their prescription is for a 30-, 60- or 90-day supply of VOQUEZNA 10 mg or 20 mg tablets.
• Lowest eligible cost, automatically: BlinkRx automatically identifies the lowest out-of-pocket cost available through its program, including the $0 offer when available for eligible patients, with no coupon or copay card to keep track of.
• Free home delivery and easy refills: VOQUEZNA ships directly to the patient’s door at no extra cost, and patients can schedule and receive refills without a trip to the pharmacy.
• Help with insurance requirements: BlinkRx coordinates directly with doctors’ offices on prior authorization and other insurance requirements, when needed, to help simplify the prescription process.
  
  

How to get started
Patients can ask their healthcare provider to send their prescription for VOQUEZNA tablets directly to BlinkRx U.S., Boise, Idaho. Once BlinkRx receives the prescription, patients will be sent a secure link by text or email to set up their BlinkRx patient profile and complete their order.

Who’s eligible for the $0 offer?
The $0 offer applies to VOQUEZNA tablets and is available to patients 18 years of age or older whose commercial insurance covers VOQUEZNA subject to eligibility requirements, benefit limits, and terms and conditions. The $0 offer is not available to patients whose prescriptions are paid for by a government health program as federal law prohibits Phathom from providing copay savings offers to such patients. The $0 offer is not available to Massachusetts residents, as state law does not permit manufacturer copay assistance that excludes or favors any pharmacy. Eligible commercially insured Massachusetts residents may pay as little as $25 for a 30-day supply, $50 for a 60-day supply, or $90 for a 90-day supply of VOQUEZNA with the VOQUEZNA Savings Card at BlinkRx or participating retail pharmacies.

Additional ways to save on VOQUEZNA
Retail pharmacies: Eligible patients with commercial insurance who prefer a retail pharmacy can continue to use the VOQUEZNA Savings Card and may pay as little as $25 for a 30-day supply, subject to eligibility requirements, benefit limits, and terms and conditions.

Cash-pay option: Eligible patients without insurance or whose insurance does not cover VOQUEZNA may pay as little as $55 for a 30-day supply through BlinkRx. This cash-pay option is only available through BlinkRx.

Phathom reserves the right to change or discontinue these offers at any time without notice. See full terms and learn more at www.VOQUEZNA.com/cost-and-savings.

About Gastroesophageal Reflux Disease (GERD)
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid flows back into the esophagus. An estimated 15 million U.S. adults are treated for GERD with a prescription medication. GERD has two main forms. Non-Erosive GERD, the most common form, causes symptoms such as frequent heartburn, regurgitation, difficulty swallowing and chest pain without visible damage to the esophagus. Erosive GERD, also called Erosive Esophagitis, involves erosions in the lining of the esophagus caused by stomach acid and, when inadequately treated, can progress to more serious conditions, including Barrett’s esophagus and esophageal cancer.
