Teva and Sanofi Announce Accelerated Timeline for Anti-TL1A Phase 2b Program in Patients with Inflammatory Bowel Disease

• Enrollment acceleration drives earlier-than-anticipated data availability for this potentially best-in-class IBD treatment
• Topline results for both UC and CD now anticipated in Q4 2024
• Teva and Sanofi are collaborating to co-develop and co-commercialize duvakitug (anti-TL1A) for moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD) patients

Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) and Sanofi today announced an update to the timing for the anti-TL1A, duvakitug (formerly known as TEV-'574/SAR447189) program investigating the human IgG1-λ2 monoclonal antibody targeting TL1A for moderate-to-severe IBD.

Patient enrollment in the RELIEVE UCCD (ulcerative colitis and Crohn's disease) Phase 2b trial has completed early due to significant acceleration in patient recruitment. As a result, Teva and Sanofi now anticipate having topline results for both UC and CD in Q4 2024, and detailed results will be presented in a scientific forum in 2025. This adjustment replaces the previously planned interim analysis for the second half of 2024, which will not be conducted. Teva and Sanofi are collaborating to co-develop and co-commercialize duvakitug for moderate-to-severe UC and CD patients.

About the Collaboration

On October 3, 2023, Teva and Sanofi entered into an exclusive collaboration to co-develop and co-commercialize Teva's duvakitug (anti-TL1A) for the treatment of UC and CD, two types of IBD. Under the terms of the agreement, in partial consideration of licenses granted to Sanofi, Teva received an upfront payment of $500 million shortly after closing and may receive up to $1 billion in development and launch milestones. Each company will equally share the remaining development costs globally and net profits and losses in major markets, with other markets subject to a royalty arrangement. 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 a chronic autoimmune disorder characterized by chronic inflammation of the gastrointestinal (GI) tract. The two main types of IBD are ulcerative colitis (UC) and Crohn's disease (CD).¹ UC and CD are chronic inflammatory conditions of 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. There is currently no cure for IBD – the goal of treatment is to induce and maintain remission and prevent flares.² Globally, approximately 4.9 million cases of IBD have been identified, with incidence rising in several regions.³

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 duvakitug (anti-TL1A) 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 duvakitug (anti-TL1A) 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.^4,5

About Duvakitug (Anti-TL1A)

Duvakitug (anti-TL1A) is a potential best-in-class human IgG1-λ2 monoclonal antibody that targets tumor necrosis factor (TNF)-like ligand 1A (TL1A), also known as TNF superfamily member 15 (TNFSF15). TL1A signaling is believed to amplify inflammation and drives fibrosis associated with inflammatory bowel disease (IBD); thus, targeting TL1A with duvakitug may mitigate the over-active immune response in these conditions. Duvakitug (anti-TL1A) is currently in Phase 2b clinical trials for the treatment of ulcerative colitis (UC) and Crohn's disease (CD), two types of inflammatory bowel disease. The safety and efficacy of duvakitug (anti-TL1A) have not been reviewed by any regulatory authority.
