Teva Presents New Data Supporting Safety, Tolerability and Target Engagement of Anti-TL1A (TEV-‘574) Antibody at the 2024 ECCO Annual Meeting

• Results demonstrate rapid and sustained suppression of free TL1A, confirming target engagement of anti-TL1A (TEV-’574)¹
• Anti-TL1A (TEV-’574) was shown to be safe and well-tolerated, with a low incidence of antidrug antibodies²
• Data support the ongoing Phase 2b clinical investigation of anti-TL1A (TEV-’574) in inflammatory bowel disease³

Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), today announced positive safety, tolerability, and pharmacokinetic data for its anti-TL1A (TEV-’574) asset, a potentially best-in-class human IgG1 monoclonal antibody that targets the tumor necrosis factor (TNF)-like ligand 1A (TL1A) and is designed to offer both anti-inflammatory and anti-fibrotic effects.^1-3

The data show the rapid and sustained suppression of free TL1A, confirming the target engagement of anti-TL1A (TEV-’574), and show a well-tolerated safety profile in patients with asthma, which support continued clinical investigation for moderate-to-severe inflammatory bowel disease (IBD); this includes ulcerative colitis (UC) and Crohn's disease (CD).^1-3 These findings will be presented at the 19th Annual Congress of the European Crohn’s and Colitis Organisation (ECCO), which takes place February 21-24, 2024, in Stockholm, Sweden.

“These results from the first-in-human trials of anti-TL1A (TEV-’574) are exciting because they show that it effectively engages with the TL1A target, supports its safety profile and is well-tolerated. This aligns with our extensive pre-clinical evidence and further supports ongoing clinical investigations of anti-TL1A (TEV-’574) in IBD, where TL1A plays a prominent role in amplification of immune response leading to burdensome inflammation and fibrosis in the gastrointestinal tract,” said Dr. Eric Hughes, Executive Vice President of Global R&D and Chief Medical Officer at Teva. “We are currently investigating the efficacy and safety of anti-TL1A (TEV-’574) in IBD through the RELIEVE UCCD Phase 2 trial, which features an innovative and efficient basket study design allowing the inclusion of patients with either type of IBD (ulcerative colitis and Crohn’s disease). These data reinforce the potential for anti-TL1A (TEV-’574) to become a novel treatment option for IBD and solidifies our ongoing commitment to provide innovative medicines to improve the lives of people living with IBD, as quickly as possible.”

First-in-human pharmacokinetic and safety data for anti-TL1A (TEV-'574) from a Phase 1 study in healthy volunteers and patients with mild asthma and a Phase 2 study in patients with severe asthma show:

• Dose-proportional increases in anti-TL1A (TEV-’574) exposure and minimal accumulation after multiple dosing every two weeks.¹
• A rapid and prolonged decrease in free TL1A levels indicating successful target engagement. This decrease was sustained up to two months after the last dose despite low or undetectable anti-TL1A (TEV-'574) levels.¹
• A favorable safety profile and well tolerated up to doses of 2300mg.^1,2

Also to be presented at ECCO 2024 is the study design of the RELIEVE UCCD Phase 2 trial investigating the efficacy and safety of anti-TL1A (TEV-’574) in patients with moderate-to-severe UC or CD.³ This first-ever basket study design for an IBD trial offers an efficient approach to help advance anti-TL1A (TEV-’574) to Phase 3 studies.

On November 30, 2023, Teva and Sanofi (EURONEXT: SAN and NASDAQ: SNY) announced the closing of their collaboration deal to co-develop and co-commercialize anti-TL1A (TEV-‘574) for the treatment of UC and CD, two types of inflammatory bowel disease.⁴ Under the terms of the agreement, Teva received an upfront payment of $500 million shortly after closing and will receive up to $1 billion in development and launch milestones. Each company will equally share the development costs globally and net profits and losses in major markets, with other markets subject to a royalty arrangement, and Sanofi will lead the development of the Phase 3 program. Teva will lead commercialization of the product in Europe, Israel and specified other countries, and Sanofi will lead commercialization in North America, Japan, other parts of Asia and the rest of the world.

About Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is the term for two conditions ― Crohn’s disease (CD) and ulcerative colitis (UC) ― characterized by chronic inflammation of the gastrointestinal (GI) tract.⁵ CD and UC are chronic inflammatory conditions in the GI tract characterized by repetitive cycles of relapses and remission. Prolonged inflammation can lead to damage within the GI tract, including fibrosis, a common complication of IBD characterized by an excessive accumulation of scar tissue in the intestinal wall, which may cause narrowing and obstruction. Common symptoms of both conditions include persistent diarrhea, rectal bleeding, abdominal pain, loss of appetite, and weight loss. No cure exists for IBD – the goal of treatment is to induce and maintain remission and prevent flares.⁶ Globally, ~4.9 million cases of IBD have been identified, with incidence rising in several regions.⁷

About RELIEVE UCCD

RELIEVE UCCD is a 14-week Phase 2b, randomized, double-blind, dose-ranging study to determine the pharmacokinetics, efficacy, safety, and tolerability of anti-TL1A (TEV-’574) in adults with ulcerative colitis (UC) or Crohn's disease (CD). In the trial, patients who meet pre-specified inclusion criteria are randomized to subcutaneously receive either one of two anti-TL1A (TEV-’574) dose regimens or placebo in a 1:1:1 ratio (stratified by diagnosis [UC or CD] and previous exposure to advanced IBD therapy [biologics and small molecules]) for 14 weeks. Participants who complete the 14-week induction period have the option to enter the long-term extension (LTE), consisting of a 44-week maintenance period for responders and a re-induction period for non-responders. Primary efficacy endpoints for both the 14-week and 44-week LTE study are number of participants with moderate-to-severe UC who show clinical remission (as defined by the modified Mayo score) and the number of participants with moderate-to-severe CD who show an endoscopic response (as defined by the endoscopic score for CD). The trial includes sites in the U.S., Canada, Europe, and Asia.^8,9

About Anti-TL1A (TEV-’574)

Anti-TL1A (TEV-’574) is a potentially best-in-class human IgG1 monoclonal antibody that targets tumor necrosis factor (TNF)-like ligand 1A (TL1A), also known as TNF superfamily member 15. TL1A signaling is believed to amplify inflammation and drives fibrosis associated with asthma and inflammatory bowel disease (IBD); thus, targeting TL1A with TEV-’574 may mitigate the over-active immune response in these conditions. Anti-TL1A (TEV-’574) is currently in Phase 2b clinical trials for the treatment of ulcerative colitis (UD) and Crohn's disease (CD), two types of inflammatory bowel disease. The safety and efficacy of anti-TL1A (TEV-’574) have not been reviewed by any regulatory authority.
