- Duvakitug was well tolerated and safety was consistent with the induction study

PARSIPPANY, N.J. and PARIS, Feb. 17, 2026 (GLOBE NEWSWIRE) -- Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), and Sanofi announced positive results from the RELIEVE UCCD long-term extension (LTE) study of duvakitug, an investigational human monoclonal antibody targeting TL1A, which showed durable clinical and endoscopic efficacy maintained over 44 weeks in patients with ulcerative colitis (UC) and Crohn's disease (CD) that initially responded to the induction phase. RELIEVE UCCD LTE is a double-blind randomized study evaluating the long-term efficacy, safety, and tolerability of duvakitug in UC and CD, the two most common forms of inflammatory bowel disease (IBD).
These longer duration data reinforce the efficacy from the RELIEVE UCCD phase 2b induction study, which demonstrated that patients achieved clinically meaningful response with duvakitug compared to placebo at week 14.
“One of the persistent challenges in treating ulcerative colitis and Crohn's disease isn't just achieving an initial response, but sustaining it,” said Eric Hughes, MD, PhD, Executive Vice President, Global R&D and Chief Medical Officer at Teva. “These Phase 2b results further reinforce TL1A as a compelling target and clearly strengthen the case that duvakitug has the potential to be a best-in-class therapy. They also provide further evidence to support additional indications we anticipate announcing this year, with the goal of bringing meaningful innovation to patients.”
The study enrolled 130 patients who responded to duvakitug in the RELIEVE UCCD induction study and entered a 44-week maintenance period. Patients were re-randomized to receive either a 450 mg or 900 mg subcutaneous dose of duvakitug every four weeks for up to a total of 58 weeks of exposure. At week 44 of the maintenance period:
- UC: 58% (900 mg) and 47% (450 mg) of patients treated with duvakitug achieved the primary endpoint of clinical remission per the modified Mayo score (mMS).
- CD: 55% (900 mg) and 41% (450 mg) of patients treated with duvakitug achieved the primary endpoint of endoscopic response as defined by the Simple Endoscopic Score for CD (SES-CD).
- In both UC and CD, consistent benefits were observed across additional efficacy endpoints.
Both doses of duvakitug were well tolerated. The most frequent observed adverse events (≥5% of all patients) with pooled duvakitug doses were upper respiratory tract infection, nasopharyngitis, Crohn's disease, and hypertension and were consistent with the RELIEVE UCCD phase 2b induction study. Detailed results from the study will be presented at a forthcoming medical meeting.
“These results reinforce duvakitug's potential as a leading TL1A therapy and an important advancement in inflammatory bowel disease treatment with durable efficacy maintained for nearly one year in patients living with ulcerative colitis or Crohn's disease,” said Houman Ashrafian, Executive Vice President, Head of Research and Development, Sanofi. “With phase 3 studies underway, we're committed to advancing duvakitug for patients who need new options, and it remains a key opportunity in our pipeline.”

About IBD
IBD is an autoimmune disorder characterized by chronic inflammation of the gastrointestinal (GI) tract. Globally, approximately 4.9 million cases of IBD have been identified, with incidence rising in several regions. The two main types of IBD are UC and CD, which are characterized by repetitive cycles of relapses and remission. Common symptoms of both conditions include persistent diarrhea, rectal bleeding, abdominal pain, loss of appetite, and weight loss.
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.
Currently, there is no cure for IBD. The goal of current treatment is to induce and maintain remission and prevent flares.
About the RELIEVE UCCD phase 2b program
The RELIEVE UCCD program is comprised of an induction study and a long-term extension.
RELIEVE UCCD: A 14-week phase 2b, randomized, double-blinded, dose-ranging induction study to evaluate the efficacy, safety, pharmacokinetics, and tolerability of duvakitug in adults with moderate-to-severe UC or CD. The study was an innovative and efficient basket study design allowing the inclusion of patients with either UC or CD. It is the first and only randomized, blinded and placebo-controlled phase 2 study to investigate the impact of TL1A in CD.
RELIEVE UCCD LTE: An ongoing study to evaluate the long-term efficacy and safety of duvakitug. Patients who received duvakitug, completed the 14-week induction study, and were responders, entered a 44-week double-blind maintenance period and were re-randomized to receive either 450 mg or 900 mg of subcutaneous duvakitug every four weeks. Patients who completed the 44-week maintenance period may continue to receive duvakitug in an open-label extension.
Primary efficacy endpoints for both the 14-week induction study and the 44-week maintenance period are clinical remission (as defined by mMS) in the UC cohort or endoscopic response (as defined by SES-CD) in the CD cohort. The study includes sites in the US, Europe, Israel, and Asia.
About duvakitug
Duvakitug, a human monoclonal antibody targeting TL1A, is currently in phase 3 clinical studies for the treatment of UC and CD. TL1A signaling is believed to amplify inflammation and drive fibrosis associated with IBD through binding to its receptor, DR3. Duvakitug preferentially inhibits TL1A-DR3 signaling over DcR3 (decoy receptor 3) binding, with the potential to reduce inflammation and fibrosis.
The safety and efficacy of duvakitug have not been reviewed by any regulatory authority.
About the Teva and Sanofi collaboration
Teva and Sanofi are collaborating to co-develop and co-commercialize duvakitug for the treatment of UC and CD. Each company will equally share the development costs globally, and the net profits and losses in major markets, with other markets subject to a royalty arrangement. Sanofi is leading the phase 3 clinical development 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.
