The deal aims to accelerate Talicia’s entry into new Middle East markets
--
Under the terms of the agreement RedHill will receive $500,000 in guaranteed payments,
including a $250,000 upfront payment and $250,000 in fixed payments due within 18 months,
plus a minimum of $1.3 million in near-term potential milestone payments, as well as tiered
royalties up to mid-teens percent on Talicia net sales
--
Talicia is the
only FDA-approved all-in-one, low-dose rifabutin-based therapy to address H.
pylori antibiotic
resistance. It is the #1 branded U.S. gastroenterologist-prescribed H. pylori
therapy1and is first-line treatment listed in the American College of Gastroenterology (ACG)
Clinical
Guidelines2
--
H. pylori, a
bacterial infection affecting >50% of the world’s adult population3, and up to almost
80% in parts of
the Middle East4, is a WHO-designated Group 1 carcinogen and key risk factor
for gastric
cancer5, which causes around 800,000 deaths globally6
--
Talicia is patent protected through 2042 and received eight years of U.S. market exclusivity
under its Qualified Infectious Disease Product (QIDP) designation
RALEIGH, N.C., October 6, 2025 -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (“RedHill” or the “Company”), a specialty
biopharmaceutical company, today announced the licensing of Talicia for new Middle East markets in a deal worth potentially $1.8 million plus sales royalty payments.
Under the terms of the agreement, RedHill will receive $500,000 in guaranteed payments, including a $250,000 upfront payment and
$250,000 in fixed payments due within 18 months. In addition, RedHill may receive a minimum of $1.3 million in near-term potential milestone payments, as well as tiered royalties up to mid-teens percent on Talicia net sales.
“With efficacy of up to 90%, a benign safety profile, zero to minimal resistance to its antibiotic components, and a convenient
all-in-one capsule formulation with a simplified, adherence-enhancing dosing schedule7,8,9, Talicia provides a compelling defense against the risk of gastric cancer through eradication of H. pylori – especially against the backdrop of increased antibiotic resistance to clarithromycin-containing therapies which can result in treatment failure rates of
up to 40%10,” said Rick Scruggs, RedHill's Chief Commercial Officer. “RedHill is committed to expanding patient access to Talicia
globally and we now have an excellent opportunity for market building in the region, where we know there is a significant medical need for effective H.
pylori treatment. Additional geographic expansion efforts are also ongoing to broaden market access and to secure additional non-dilutive ex-US licensing revenue streams.”
The need for effective H. pylori
treatment, designed to address antibiotic resistance, is clear. There is a high and rising prevalence of H. pylori antibiotic resistance, and
leading U.S. H. pylori treatment guidelines are explicit on the need to avoid using clarithromycin as part of any H. pylori treatment regimen without prior susceptibility testing. H.
pylori is a key risk factor for gastric cancer, which causes approximately 800,000 deaths a year globally - despite it being known that eradication of H. pylori can lead to a 75% decreased gastric cancer risk11.
Talicia is the number one branded H.
pylori therapy prescribed by U.S. gastroenterologists. It is listed as a first-line option for the treatment of H. pylori infection
in the American College of Gastroenterology (ACG) Clinical Guideline, Talicia is the only FDA-approved all-in-one, low-dose rifabutin-based therapy designed to address H. pylori resistance to other antibiotics commonly used in H. pylori therapies.
Talicia is patent protected through 2042 and received eight years of U.S. market exclusivity under its Qualified Infectious Disease
Product (QIDP) designation.
About H. pylori
H. pylori is a bacterial
infection that affects approximately 35% of the U.S. adult population12 (an estimated 1.6 million U.S. patients are treated annually) rising to more than 50% globally13 and reaching even higher levels of almost 80% in parts
of the Middle East. Classified by the World Health Organization (WHO) as a Group 1 carcinogen, H. pylori is the strongest known risk factor
for gastric cancer (between 70% to 90% of cases with more than 27,000 Americans diagnosed with gastric cancer annually14 and approximately 800,000 deaths globally per year), a major risk factor for peptic ulcer disease (90% of cases)15
and gastric mucosa-associated lymphoid tissue (MALT) lymphoma16. Eradication of H. pylori is becoming increasingly difficult, with
current therapies failing in approximately 25-40% of patients who remain H. pylori-positive due to high resistance of H. pylori to antibiotics – especially clarithromycin – which is still commonly used in standard combination therapies17.

About Talicia®
Approved by the FDA for the treatment of H. pylori infection in adults in November 2019, Talicia is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (omeprazole). Talicia received eight
years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents extending patent protection through 2042 with additional patents and applications pending and granted in
various territories worldwide. Talicia is also approved by the United Arab Emirates (UAE) Ministry of Health.
