Brief Summary
The purpose of the study is to evaluate the efficacy, safety, and tolerability of VIB4920 (formerly MEDI4920) in adult participants with Sjögren's Syndrome (SS).
Detailed Description
The study will enrol 2 SS populations: Population 1 will include participants with moderate to high systemic disease activity defined by European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI) >= 5; Population 2 will include participants with moderate to severe subjective symptoms defined by EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) score >= 5 and residual stimulated salivary flow but with mild systemic disease activity defined by ESSDAI score < 5. This study will include 3 periods: screening (4 weeks), treatment period (40 Weeks) and follow-up period (12 weeks). In the treatment period, participants from each of the populations will be randomized at 1:1 ratio to receive intravenous (IV) dose of VIB4920 or placebo (Stage I). After completion of Stage I, participants randomized to VIB4920 in Stage I will receive placebo and participants randomized to placebo in Stage I will receive VIB4920 (Stage II). Participants who had study drug discontinuation will not be eligible for treatment during Stage II. All participants will be followed for at least 12 weeks after their last dose of study drug administration.
Study acquired from Horizon in 2024.

Description
Time Frame
Population 1: Change From Baseline in ESSDAI at Day 169
The ESSDAI is a systemic disease activity index for SS, assessing 12 domains (Constitutional, Salivary Glands, Lungs, Kidneys, Musculoskeletal, Peripheral Nervous System, Central Nervous System, Vascular, Gastrointestinal, Hematological, Ocular, and Extraglandular Manifestations). Each domain is graded for activity (0 = no activity to 3 = high activity) and weighted (1 for Biological to 6 for Muscular) based on its clinical significance, with the final score calculated as the sum of all weighted domain scores. The theoretical range is 0 to 123, with disease activity categorized as low (<5), moderate (5-13), and high (≥14). A positive change form baseline represents an increase in symptoms.
Baseline and Day 169
Population 2: Change From Baseline in ESSPRI at Day 169
The ESSPRI is a self-assessment tool for evaluating symptoms of dryness, fatigue, and pain (articular and/or muscular) in SS. Participants rate each of the three domains on a 0-10 numerical scale (0 = no; 10 maximal imaginable severity). All domains are equally weighted, and the total score is the mean of the three domain scores. The maximum total score for the ESSPRI assessment is 10. A positive change form baseline represents an increase in symptoms.

Population 1: Placebo/VIB4920
Participants with SS characterized by moderate to severe systemic disease activity (defined by an ESSDAI score of ≥ 5), were randomized to receive a placebo in Stage I, followed by VIB4920 in Stage II.
Population 1: Number of Participants Who Achieved ESSDAI[3] and ESSDAI[4] Response at Day 169
The ESSDAI is a systemic disease activity index for primary Sjögren's syndrome, assessing 12 domains (e.g., cutaneous, renal, CNS, and biological). Each domain is graded for activity (0 = no activity to 3 = high activity) and weighted (1 for Biological to 6 for Muscular) based on its clinical significance, with the final score calculated as the sum of all weighted domain scores. The theoretical range is 0 to 123, with disease activity categorized as low (<5), moderate (5-13), and high (≥14). A positive change from baseline represents an increase in symptoms.
ESSEDAI[3] and [4] responses were defined as a decrease of at least 3 or 4 points respectively in the ESSDAI score from the baseline value, measured at Day 169.
Day 169
Change From Baseline in The Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Day 169
The FACIT-Fatigue is a 13-item patient-reported questionnaire designed to assess the impact of fatigue on quality of life (QoL). Responses are scored from 0 (Not at all) to 4 (Very Much). The total score is the sum of all responses, ranging from 0 to 52, with higher scores indicating better QoL. A positive change from baseline represents an increase in QoL.
Baseline and Day 169
Change From Baseline in Ocular Surface Disease Index (OSDI) at Day 169
The OSDI is a validated tool for assessing vision-related function and dry eye disease severity (normal, mild, moderate, severe). It consists of 12 questions, with responses ranging from 0 (None of the time) to 4 (All of the time). Scores range from 0 to 100, as it is calculated by transforming the raw responses from the 12 questions into a standardized 0-100 scale, with higher scores indicating greater disability. A positive change from baseline indicates a worsening vision-related function.
Baseline and Day 169
Patient Global Impression of Severity (PGIS) Score at Day 169
The PGIS is a single-item measure that captures a patient's perception of overall symptom severity over the past week, using a 5-point categorical response scale (0 = none, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe), with higher scores indicating greater symptom severity. Positive change from baseline values indicate worsening of symptoms severity.
Baseline and Day 169
Population 2: Number of Participants Who Achieved ESSPRI Response at Day 169
The ESSPRI is a self-assessment tool for evaluating symptoms of dryness, fatigue, and pain (articular and/or muscular) in SS. Participants rate each of the three domains on a 0-10 numerical scale (0 = no; 10 maximal imaginable severity). All domains are equally weighted, and the total score is the mean of the three domain scores. The maximum total score for the ESSPRI assessment is 10. A positive change form baseline represents an increase in symptoms. Participants achieving an ESSPRI response were defined as at least a 1 point or 15% reduction from baseline in ESSPRI score at Day 169 without premature discontinuation from the study and without receiving rescue medications.
Day 169
Number of Participants Who Experience Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) referred to any untoward medical occurrence in a clinical study participant, regardless of a causal relationship with the study treatment. TEAEs included any event occurring after the participant received the study treatment. Clinically significant changes in vital signs, electrocardiograms, and laboratory tests recorded after treatment administration were documented as TEAEs. Serious TEAEs (SAEs) were untoward medical occurrences after the first dose, irrespective of a causal link to the study treatment, that led to death, were life-threatening, required hospitalization or its prolongation, caused significant disability, resulted in congenital anomalies, or were considered other medically important events. AEs were graded (Grade 3: severe; Grade 4: life-threatening; Grade 5: death) using the Common Terminology Criteria for Adverse Events (CTCAE).

Population 1: Number of Participants Who Achieved ESSDAI[3] and ESSDAI[4] Response at Day 169
The ESSDAI is a systemic disease activity index for primary Sjögren's syndrome, assessing 12 domains (e.g., cutaneous, renal, CNS, and biological). Each domain is graded for activity (0 = no activity to 3 = high activity) and weighted (1 for Biological to 6 for Muscular) based on its clinical significance, with the final score calculated as the sum of all weighted domain scores. The theoretical range is 0 to 123, with disease activity categorized as low (<5), moderate (5-13), and high (≥14). A positive change from baseline represents an increase in symptoms.
ESSEDAI[3] and [4] responses were defined as a decrease of at least 3 or 4 points respectively in the ESSDAI score from the baseline value, measured at Day 169.
FAS: included all randomized participants who received any dose of investigational product, analyzed according to the randomized treatment, and had available data at the specified time points.

Change From Baseline in The Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Day 169
The FACIT-Fatigue is a 13-item patient-reported questionnaire designed to assess the impact of fatigue on quality of life (QoL). Responses are scored from 0 (Not at all) to 4 (Very Much). The total score is the sum of all responses, ranging from 0 to 52, with higher scores indicating better QoL. A positive change from baseline represents an increase in QoL.

Change From Baseline in Ocular Surface Disease Index (OSDI) at Day 169
The OSDI is a validated tool for assessing vision-related function and dry eye disease severity (normal, mild, moderate, severe). It consists of 12 questions, with responses ranging from 0 (None of the time) to 4 (All of the time). Scores range from 0 to 100, as it is calculated by transforming the raw responses from the 12 questions into a standardized 0-100 scale, with higher scores indicating greater disability. A positive change from baseline indicates a worsening vision-related function.

Patient Global Impression of Severity (PGIS) Score at Day 169
The PGIS is a single-item measure that captures a patient's perception of overall symptom severity over the past week, using a 5-point categorical response scale (0 = none, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe), with higher scores indicating greater symptom severity. Positive change from baseline values indicate worsening of symptoms severity.

Population 2: Number of Participants Who Achieved ESSPRI Response at Day 169
The ESSPRI is a self-assessment tool for evaluating symptoms of dryness, fatigue, and pain (articular and/or muscular) in SS. Participants rate each of the three domains on a 0-10 numerical scale (0 = no; 10 maximal imaginable severity). All domains are equally weighted, and the total score is the mean of the three domain scores. The maximum total score for the ESSPRI assessment is 10. A positive change form baseline represents an increase in symptoms. Participants achieving an ESSPRI response were defined as at least a 1 point or 15% reduction from baseline in ESSPRI score at Day 169 without premature discontinuation from the study and without receiving rescue medications.

Number of Participants Who Experience Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) referred to any untoward medical occurrence in a clinical study participant, regardless of a causal relationship with the study treatment. TEAEs included any event occurring after the participant received the study treatment. Clinically significant changes in vital signs, electrocardiograms, and laboratory tests recorded after treatment administration were documented as TEAEs. Serious TEAEs (SAEs) were untoward medical occurrences after the first dose, irrespective of a causal link to the study treatment, that led to death, were life-threatening, required hospitalization or its prolongation, caused significant disability, resulted in congenital anomalies, or were considered other medically important events. AEs were graded (Grade 3: severe; Grade 4: life-threatening; Grade 5: death) using the Common Terminology Criteria for Adverse Events (CTCAE).

Other Details
The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
