H. pylori bacterial infection is a Group 1 carcinogen and the strongest risk factor for gastric cancer; H. pylori affects approximately 35% of the U.S. population

TEL-AVIV, ISRAEL and RALEIGH, NC / ACCESSWIRE / July 20, 2021 / RedHill Biopharma Ltd. (Nasdaq:RDHL) ('RedHill' or the 'Company'), a specialty biopharmaceutical company, today announced that OptumRx, part of the UnitedHealth Group - a leader in healthcare coverage, partnered with more than 1.3 million healthcare professionals and 6,500 hospitals, has added Talicia^® (omeprazole magnesium, amoxicillin and rifabutin)^[1] to its Commercial Formulary as an unrestricted brand for H. pylori treatment, effective July 1, 2021.

'Momentum with Talicia is growing strongly and the addition of unrestricted Commercial coverage for Talicia by OptumRx, a major operator in U.S. healthcare coverage serving more than 26 million Americans, is an important advance in extending patient access to Talicia, which now extends to greater than 8 out of 10 covered U.S. Commercial lives,' said Rick Scruggs, RedHill's Chief Commercial Officer. 'Talicia is the first and only FDA-approved rifabutin-based therapy for the treatment of H. pylori infection, and this listing represents the understanding within the medical community of the need to combat the high and growing resistance of H. pylori to commonly used antibiotics with an effective new first-line treatment.'

About Talicia^®
Talicia^® is the only rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address the high resistance of H. pylori bacteria to clarithromycin-based therapies. The high rates of H. pylori resistance to clarithromycin have led to significant rates of treatment failure with clarithromycin-based therapies and are a strong public health concern, as highlighted by the FDA and the World Health Organization (WHO) in recent years.

Talicia^® is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (PPI) (omeprazole). In November 2019, Talicia^® was approved by the U.S. FDA for the treatment of H. pylori infection in adults. In the pivotal Phase 3 study, Talicia^® demonstrated 84% eradication of H. pylori infection in the intent-to-treat (ITT) group vs. 58% in the active comparator arm (p<0.0001). Minimal to zero resistance to rifabutin, a key component of Talicia®, was detected in RedHill's pivotal Phase 3 study. Further, in an analysis of data from this study, it was observed that subjects who were confirmed adherent^[2] to their therapy had response rates of 90.3% in the Talicia^® arm vs. 64.7% in the active comparator arm^[3].

Talicia^® is eligible for a total of eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents which extend patent protection until 2034 with additional patents and applications pending and granted in various territories worldwide.

About H. pylori
H. pylori is a bacterial infection that affects approximately 35%^[4] of the U.S. population, with an estimated two million patients treated annually^[5]. Worldwide, more than 50% of the population has
H. pylori infection, which is classified by the WHO as a Group 1 carcinogen. It remains the strongest known risk factor for gastric cancer^[6] and a major risk factor for peptic ulcer disease^[7] and gastric mucosa-associated lymphoid tissue (MALT) lymphoma^[8]. More than 27,000 Americans are diagnosed with gastric cancer annually^[9]. 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 commonly used in standard combination therapies^[10].
