FLORHAM PARK, N.J., Nov. 28, 2023 (GLOBE NEWSWIRE) – Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal (GI) diseases, today announced the U.S. commercial availability of VOQUEZNA® (vonoprazan). VOQUEZNA is now available for the treatment of adults with Erosive Esophagitis, also known as Erosive GERD (gastroesophageal reflux disease), and the relief of heartburn associated with Erosive GERD.1 As the first and only approved potassium-competitive acid blocker (PCAB) in the U.S., this milestone brings the power of a new class of acid suppression treatment to a disease with high unmet need.
“We are thrilled to announce the commercial availability of our first-in-class medication, VOQUEZNA, now available for the millions of people in the U.S. suffering from Erosive GERD,” said Martin Gilligan, Chief Commercial Officer at Phathom Pharmaceuticals. “For over three decades, there has been no major innovation in this category. We are excited to introduce VOQUEZNA to patients and healthcare providers, as it has been shown to provide rapid, potent, and durable acid suppression and has the power to help heal Erosive GERD for patients seeking a new and effective treatment option.”
The U.S. Food and Drug Administration (FDA) recently approved VOQUEZNA for the healing of all severities (grades) of Erosive GERD, maintenance of healing of all severities of Erosive GERD, and relief of heartburn associated with Erosive GERD in adults.1 Its novel mechanism of action (MOA) provides rapid, potent, and durable acid suppression in a way that is distinct from other prescription and over-the-counter medications.2 Additionally,VOQUEZNA does not have the burden of mealtime dosing, whereas most PPIs must always be taken with food.1
In a Phase 3, randomized clinical study, VOQUEZNA 20 mg met the primary endpoint of non-inferiority for complete healing by Week 8 in patients with all severities of Erosive GERD, demonstrating a strong healing rate of 93% compared to 85% for lansoprazole 30 mg, with superior rates of healing demonstrated in a secondary endpoint in patients with moderate- to-severe disease at Week 2 compared to lansoprazole (70% for VOQUEZNA 20 mg and 53% for lansoprazole 30 mg). In the maintenance phase of the study, VOQUEZNA 10 mg was superior to lansoprazole 15 mg in maintaining healing at six months in all randomized patients (79% for VOQUEZNA 10 mg, compared to 72% for lansoprazole 15 mg).
The most common side effects of VOQUEZNA for the treatment of Erosive GERD include stomach inflammation, diarrhea, stomach bloating, stomach pain, nausea, indigestion, high blood pressure, and urinary tract infection.
“Erosive GERD is a highly prevalent condition affecting over 20 million people in the U.S.,3,4 many of whom experience troubling symptoms, including painful heartburn. When not properly treated, Erosive GERD can lead to complications such as scarring, narrowing of the esophagus, and bleeding,4” said Colin Howden, M.D., ProfessorEmeritus, University of Tennessee College of Medicine. “With many patients unsatisfied with their current therapy,5 the introduction of VOQUEZNA provides healthcare providers and patients with an important new treatment option that offers a novel mechanism of action and has demonstrated superiority in comparison to a standard-of-care PPI across several clinically meaningful endpoints.2”
Prescriptions for VOQUEZNA may be filled at major retail pharmacies and through BlinkRx, an end-to-end digital fulfillment channel. Phathom is offering programs for eligible patients who face coverage or affordability issues, including co-pay assistance for patients with commercial insurance.
