- Teva-discovered TEV ‘408, a novel anti-IL-15 monoclonal antibody, demonstrated statistically significant and clinically meaningful prevention of gluten-induced intestinal damage vs placebo following a single subcutaneous dose.
- TEV ‘408 was well-tolerated with no safety signals observed to date.
- Together with the vitiligo program, the celiac disease topline results further support TEV ‘408 as a potential pipeline-in-a-product opportunity in multiple diseases.

TEL AVIV, Israel, Sept. 02, 2026 (GLOBE NEWSWIRE) — Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) today announced positive topline results from an ongoing Phase 2a study of TEV ‘408, an investigational anti-interleukin-15 monoclonal antibody, in adults with celiac disease. The study met its primary endpoint, demonstrating statistically significant and clinically meaningful prevention of gluten-induced intestinal damage versus placebo at week 8. TEV ‘408 was well-tolerated, with no safety signals observed to date.
“A strict gluten-free diet has long been the only option for people living with celiac disease. Yet, even with strict adherence to a gluten-free diet, many continue to experience symptoms, intestinal damage and a significant impact on their daily lives,” said Eric Hughes, MD, PhD, Executive Vice President, Global R&D and Chief Medical Officer at Teva. “These results underscore the potential to move beyond managing gluten exposure and address celiac disease at its biological source. They also strengthen our confidence in targeting the IL-15 pathway as an approach to reducing immune-driven intestinal damage.”
The ongoing randomized, placebo-controlled study enrolled 50 adult participants with celiac disease on a gluten-free diet (GFD) with minimal intestinal damage at baseline as measured by the villous height-to-crypt depth ratio (Vh:Cd ≥2.0) and symptoms. Two weeks after receiving a single dose of TEV ‘408, participants began a six-week daily gluten challenge (GC). The study assessed biopsy-based measures of intestinal damage and inflammation along with patient-reported symptoms. At week 8 (the end of the GC) TEV ‘408:
- Showed statistically significant and clinically meaningful prevention of gluten-induced intestinal damage versus placebo, as measured by the trial’s primary endpoint of Vh:Cd ratio with a least squares (LS) mean change from baseline of -0.43 compared with -0.88 for placebo (treatment difference of 0.45, 95% CI: (0.06, 0.84), p<0.05).
- Showed a favorable effect on intestinal inflammation as measured by density of intraepithelial lymphocytes (IELs) compared with placebo; the LS Mean change from baseline in the density of IELs, was an increase of 27.60 for placebo compared to 0.37 for TEV ‘408 treated participants (treatment difference of -27.23, 95% CI: (-39.67, -14.79)).
- Demonstrated lower GI symptom scores versus placebo, as assessed using the Celiac Disease Symptom Diary (CDSD), a patient-reported outcome (PRO).
- Was well-tolerated with no emerging safety signals.
Additional analyses from the ongoing Phase 2a study are underway. Teva plans to present further data from the study at a future scientific meeting.

About TEV ‘408
TEV ‘408, discovered by Teva, is an investigational human monoclonal antibody designed to inhibit interleukin-15 (IL-15), a cytokine involved in immune-mediated pathways. TEV ‘408 has a high affinity and potency (in vitro) with a prolonged half-life that supports the potential for convenient subcutaneous dosing.
TEV ‘408 is being studied as a potential therapy for celiac disease in a Phase 2a study and was granted Fast Track designation in that indication by the U.S. FDA in May 2025. By blocking IL-15 activity, TEV ‘408 aims to reduce the IL-15-driven intestinal inflammation and damage that are characteristic of celiac disease.
TEV ‘408 is also being evaluated in a Phase 1b study as a treatment for vitiligo. Following encouraging results from the ongoing Phase 1b study in vitiligo, Teva is advancing the investigational asset into a Phase 2b study in vitiligo. By blocking IL-15 activity, TEV ‘408 aims to reduce the immune-mediated destruction of melanocytes (pigment-producing cells) resulting in white patches on the skin characteristic of vitiligo.
Teva entered a strategic funding agreement with Royalty Pharma in January 2026. Under the agreement, Teva is eligible to receive up to $500 million to accelerate the clinical development of TEV ‘408. If approved and launched, Teva will pay a milestone to Royalty Pharma and a royalty on worldwide net sales of TEV ‘408.
About Celiac Disease
Celiac disease is a serious autoimmune disease in which exposure to gluten triggers an immune response that damages the small intestine. It affects approximately 1% of the global population, or more than three million people in the U.S. alone, although many individuals remain undiagnosed. Celiac disease can cause chronic digestive symptoms, fatigue, nutrient deficiencies, and other health complications that can significantly impact daily life.
There are currently no approved therapies for celiac disease. A strict gluten-free diet (GFD) remains the standard of care, yet even with careful adherence, patients may continue to experience symptoms, reduced quality of life, and ongoing intestinal inflammation or damage due to inadvertent gluten exposure. For people living with celiac disease, managing the condition often requires constant vigilance around meals, travel, work, and social activities, creating significant daily burden. The limitations of current management approaches underscore the need for therapies that address the underlying drivers of disease and improve outcomes for patients.
