Dazodalibep for Sjögren’s Disease

Michele B. Kaufman, PharmD, BCGP  |  August 26, 2025

From baseline to day 169, the participants who received dazodalibep had significantly greater improvement in the Functional Assessment of Chronic Illness Therapy-Fatigue score (LS mean ± SE: 8.1 ± 1.4) than those who received placebo (2.8 ± 1.4; P=0.0095). At day 169, participants who received dazodalibep had greater numerical improvement in the Ocular Surface Disease Index (−14.0 ± 3.0 vs. −8.5 ± 2.9; P=0.1936) and Patient’s Global Impression of Severity (−0.6 ± 0.1 vs. −0.4 ± 0.1; P=0.1781) than participants who received placebo. (Note: The Ocular Surface Disease Index assesses dry eye and its effect on a patient’s vision within the prior week.5)

Seventy-five participants reported adverse events. Half had received dazodalibep (37/54) and approximately half had received placebo (38/55). Most reactions were mild to moderate in severity. The most frequently reported adverse events in those who received dazodalibep were COVID-19, nasopharyngitis, anemia and diarrhea. There were three serious adverse events: pneumonia (influenza), post-acute COVID-19 syndrome (i.e., long COVID) and gammopathy. One participant who received placebo had neutropenia.

Investigators deemed all serious adverse events unrelated to the study medication. One participant who received dazodalibep and two participants who received placebo discontinued the study due to an adverse event, which was not defined in the abstract.

Conclusion

The primary end point was met in this phase 2 trial of dazodalibep therapy for patients with Sjögren’s disease with an unacceptable symptom burden and limited systemic organ involvement. Participants who received 1,500 mg of IV dazodalibep every two weeks for three doses and then every four weeks for an additional four doses had statistically significant and clinically meaningful improvement for key symptoms of Sjögren’s disease as measured by ESSPRI and Patient’s Global Impression of Severity when compared with placebo-treated participants.

Overall, the study found dazodalibep was generally safe and well tolerated, with limited serious adverse events. Larger clinical trials are warranted.

“As reported in another abstract from EULAR 2023, a 20-week course of dazodalibep infusions also reduced the signs and symptoms of extra­glandular involvement in those patients with Sjogren’s [disease] with at least moderately active systemic disease, as defined by an ESSDAI of ≥5,” says E. William St.Clair, MD, the lead investigator in this study and chief of the Division of Rheumatology and Immu­nology, Duke University School of Medicine, Durham, N.C.6 “Taken together, these results provide evidence that dazodalibep therapy for Sjögren’s [disease] has an acceptable balance of efficacy and safety for controlling systemic disease activity, as well as reducing symptoms of dryness, fatigue and pain.”
