BAFF/IL-17 Bispecific Antibody Treatment in Subjects With Primary Sjogren's Syndrome
Study Details
Study Description
Brief Summary
To demonstrate that tibulizumab (LY3090106) treatment improves the mean unstimulated salivary flow rate or the salivary gland total ultrasound score (TUS) in primary Sjogren's syndrome patients at week 12 compared to the baseline visit.

Detailed Description
This will be a single-site, open-label study in patients with primary Sjogren's syndrome. All patients will receive tibulizumab (LY3090106) 300mg subcutaneously every 2 weeks for a total of 12 weeks.
Primary Sjogren's syndrome was selected as a relevant patient population based on the mechanism of action of the molecule and the current understanding of the pathogenesis of the disease. An open-label design was chosen based on practical considerations regarding the number of patients that could be recruited. Although open-label studies are subject to bias, objective primary endpoints were intentionally chosen to minimize this concern.
The goal of this study is to demonstrate that tibulizumab (LY3090106) treatment improves the mean unstimulated salivary flow rate or the salivary gland total ultrasound score (TUS) in primary Sjogren's syndrome patients at week 12 compared to the baseline visit.

Outcome Measures
Primary Outcome Measures
- whole unstimulated sialometry [baseline]
change in unstimulated salivary flow
- whole unstimulated sialometry [week 12]
change in unstimulated salivary flow
- salivary gland ultrasound [baseline]
change in salivary gland ultrasound score
- salivary gland ultrasound [week 12]
change in salivary gland ultrasound score
Secondary Outcome Measures
- ESSDAI [baseline]
change in the ESSDAI disease activity score The EULAR Sjogren's Syndrome Disease Activity Index (ESSDAI) is a physician administered questionnaire containing 12 organ-specific domains designed to measure disease activity. The ESSDAI score is obtained by addition of the twelve domain scores. Each domain score is obtained by multiplying the activity level with the domain weight. The maximum theoretical ESSDAI score is 123 and the minimum score is 0. A higher score means more disease activity (worse outcome).
- ESSDAI [week 12]
change in the ESSDAI disease activity score The EULAR Sjogren's Syndrome Disease Activity Index (ESSDAI) is a physician administered questionnaire containing 12 organ-specific domains designed to measure disease activity. The ESSDAI score is obtained by addition of the twelve domain scores. Each domain score is obtained by multiplying the activity level with the domain weight. The maximum theoretical ESSDAI score is 123 and the minimum score is 0. A higher score means more disease activity (worse outcome).
- ESSPRI [baseline]
change in the ESSPRI disease activity score The EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) is a patient completed questionnaire to assess subjective patient symptoms, which includes 3 domains (dryness, fatigue, and pain). The ESSPRI score is calculated by averaging the three domains with a maximum severity score of 10 and minimum score of 0. A higher score means more disease activity (worse outcome).
- ESSPRI [week 12]
change in the ESSPRI disease activity score The EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) is a patient completed questionnaire to assess subjective patient symptoms, which includes 3 domains (dryness, fatigue, and pain). The ESSPRI score is calculated by averaging the three domains with a maximum severity score of 10 and minimum score of 0. A higher score means more disease activity (worse outcome).
- whole stimulated sialometry [baseline]
change in stimulated salivary flow rate
- whole stimulated sialometry [week 12]
change in stimulated salivary flow rate
- Schirmer I test [baseline]
change in the Schirmer I test
- Schirmer I test [week 12]
change in the Schirmer I test
- MRI [baseline]
change in MRI (parenchymal architecture scored 0 to 4 and sialography scored 0 to 4)
- MRI [week 12]
change in MRI (parenchymal architecture scored 0 to 4 and sialography scored 0 to 4)
- PET [baseline]
change in PET (parotid and submandibular gland SUVmax)
- PET [week 12]
change in PET (parotid and submandibular gland SUVmax)
