Baminercept, a Lymphotoxin-Beta Receptor Fusion Protein, for Treatment of Sjögren's Syndrome

A Randomized, Double-blind, Placebo-controlled Phase II Clinical Trial of Baminercept, a Lymphotoxin-beta Receptor Fusion Protein, for the Treatment of Primary Sjögren's Syndrome (ASJ02)

The purpose of the study is to find out if the experimental study agent, baminercept, is effective in treating patients with Sjögren's syndrome. The study will also determine if the study agent can be safely given to patients with Sjögren's syndrome; examine how it affects symptoms of the disease; and attempt to understand how baminercept affects the underlying mechanisms of Sjögren's syndrome and the immune system.

Study Overview

• Status: Terminated
• Conditions: Primary Sjögren's Syndrome
• Intervention / Treatment: Biological: Baminercept; Other: Placebo

Detailed Description

Sjögren's syndrome is an autoimmune disorder in which a person's own immune cells attack the body's tear and salivary glands. This disease is the second most common autoimmune disorder, affects close to four million people in the U.S., and has no known cause. About one-third of patients with Sjögren's syndrome have enlarged parotid glands (the largest salivary glands, the glands that make saliva); inflammation of organs such as the lungs and joints may also occur. There is no known effective treatment other than measures that can relieve symptoms. One of the most bothersome symptoms is dryness of the eyes and mouth. Eye drops and saliva stimulants (which help make more saliva) are common treatments. When other organs are affected, symptoms are treated with corticosteroids (prednisone), non-steroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen and naproxen), hydroxychloroquine (Plaquenil®) or other medications that suppress the immune system. These drugs may curb or kill cells of the immune system, but they are not always helpful, do not cure Sjögren's syndrome, and can have many side effects.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Screening in Stimulated Whole Salivary Flow at Week 24	After an unstimulated salivary flow assessment the participant was administered a single 5-mg dose of pilocarpine to stimulate saliva production. One hour after the administration of pilocarpine the participant spit into a preweighed 50-cm centrifuge tube for 15 minutes. The sample was weighed to determine the volume (1 g = 1 mL) of saliva. The volume of saliva (mL) was divided by the duration of the test (minutes) to calculate the stimulated salivary flow rate (mL/min). Change from screening was computed as the value at Week 24 minus the screening value. A positive value in change from screening indicates an improvement and a negative value indicates worsening.	Screening to Week 24

Change From Screening in Stimulated Whole Salivary Flow at Week 48	After an unstimulated salivary flow assessment the participant was administered a single 5-mg dose of pilocarpine to stimulate saliva production. One hour after the administration of pilocarpine the participant spit into a preweighed 50-cm centrifuge tube for 15 minutes. The sample was weighed to determine the volume (1 g = 1 mL) of saliva. The volume of saliva (mL) was divided by the duration of the test (minutes) to calculate the stimulated salivary flow rate (mL/min). Change from screening was computed as the value at Week 48 minus the screening value. A positive value in change from screening indicates an improvement and a negative value indicates worsening.	Screening to Week 48
Change From Screening in Unstimulated Whole Salivary Flow at Week 24	The participant spit into a preweighed 50-cm centrifuge tube for 15 minutes. The sample was weighed to determine the volume (1 g = 1 mL) of saliva. The volume of saliva (mL) was divided by the duration of the test (minutes) to calculate the unstimulated salivary flow rate (mL/min). Cholinergic stimulants such as pilocarpine or cevimeline were discontinued for 48 hours prior to the assessment and nothing was taken by mouth for 60 minutes or longer before or during saliva collection. Change from screening was computed as the value at Week 24 minus the screening value. A positive value in change from screening indicates an improvement and a negative value indicates worsening.	Screening to Week 24
Change From Screening in Unstimulated Whole Salivary Flow at Week 48	The participant spit into a preweighed 50-cm centrifuge tube for 15 minutes. The sample was weighed to determine the volume (1 g = 1 mL) of saliva. The volume of saliva (mL) was divided by the duration of the test (minutes) to calculate the unstimulated salivary flow rate (mL/min). Cholinergic stimulants such as pilocarpine or cevimeline were discontinued for 48 hours prior to the assessment and nothing was taken by mouth for 60 minutes or longer before or during saliva collection. Change from screening was computed as the value at Week 48 minus the screening value. A positive value in change from screening indicates an improvement and a negative value indicates worsening.	Screening to Week 48
Change From Baseline in European League Against Rheumatism (EULAR) Sjogren's Syndrome Disease Activity Index (ESSDAI) at Week 24	The ESSDAI is a clinical index that measures Sjogren's syndrome disease activity. A physician scores the disease activity level of twelve organ-specific domains in 3 or 4 levels according to their severity. For example, for no disease activity the domain score equals 0 and for high disease activity the domain score equals 3 or 4. Each domain is assigned a weight between 1 and 6, and the domain score is multiplied by the domain weight. The sum of the weighted domain scores is the overall score, which can range from 0 to 123. A higher score indicates more disease activity. Change from baseline was computed as the value at Week 24 minus the baseline value. A negative value in change from baseline indicates an improvement and a positive value indicates worsening.	Baseline to Week 24
Percent of Subjects Classified as Responders According to the Patient Self-Assessment of Fatigue, Overall Dryness, and Joint Pain at Week 24	Response is defined by 30% or more improvement (decrease) from baseline to week 24 in at least two of the three Visual Analog Scale (VAS) scores for patient self-assessment of symptoms of overall dryness, fatigue, and joint pain. On a 100-mm horizontal line the participant places a vertical mark to indicate a response. The range is 0 to 100, with 100 as the highest perceived overall fatigue, overall dryness, or joint pain.	Week 24
Percent of Subjects Classified as Responders According to the Patient Self-Assessment of Fatigue, Overall Dryness, and Joint Pain at Week 48	Response is defined by 30% or more improvement (decrease) from baseline to week 48 in at least two of the three Visual Analog Scale (VAS) scores for patient self-assessment of symptoms of overall dryness, fatigue, and joint pain.

A negative value in change from baseline indicates an improvement and a positive value indicates worsening.	Week 48
Change From Baseline in Tear Secretion as Measured by Schirmer's I Test at Week 24	A paper strip was placed within each lower eyelid and the participant's eyes were closed for 5 minutes. The wet paper was removed after 5 minutes and the length of wetting was recorded to the nearest 0.5 mm. Change from baseline was computed as the value at Week 24 minus the baseline value. A positive value in change from Baseline indicates an improvement and a negative value indicates worsening.	Week 24
Change From Baseline in Tear Secretion as Measured by Schirmer's I Test at Week 48	A paper strip was placed within each lower eyelid and the participant's eyes were closed for 5 minutes.

A positive value in change from Baseline indicates an improvement and a negative value indicates worsening.	Week 48
Change From Baseline in Tear Secretion as Measured by Lissamine Green Staining at Week 24	Lissamine green stain was dropped into the participant's eyes and then an ophthalmologist used a slit lamp to examine the eye surface. Six areas of the eye surface were evaluated and scored from 0 to 3, with 0 being no tear film damage to 3, extensive tear film damage. The scores of all six areas in both eyes were totaled to obtain an overall score between 0 and 18. A higher score indicates insufficient tear flow and excessive dryness. Change from baseline was computed as the value at Week 24 minus the baseline value. A negative value in change from Baseline indicates an improvement and a positive value indicates worsening.	Week 24
Change From Baseline in Tear Secretion as Measured by Lissamine Green Staining at Week 48	Lissamine green stain was dropped into the participant's eyes and then an ophthalmologist used a slit lamp to examine the eye surface. Six areas of the eye surface were evaluated and scored from 0 to 3, with 0 being no tear film damage to 3, extensive tear film damage. The scores of all six areas in both eyes were totaled to obtain an overall score between 0 and 18. A higher score indicates insufficient tear flow and excessive dryness. Change from baseline was computed as the value at Week 48 minus the baseline value. A negative value in change from Baseline indicates an improvement and a positive value indicates worsening.	Week 48
Change From Baseline in the Short Form 36 (SF-36) Physical and Mental Health Component Summary Scores (PCS and MCS) at Week 24	The SF-36 questionnaire completed by the subject measures health-related quality of life across multiple disease states. It has 36 questions with 8 subscale scores and 2 summary scores: PCS=physical functioning, role-physical, bodily pain, and general health; MCS=vitality, social functioning, role-emotional, and mental health. Scoring is done for both subscores and summary scores. For both, 0=worst score (or quality of life) and 100=best score. Summary measures were standardized to have a mean of 50 and a standard deviation of 10 in the 1998 general US population. Change from baseline is computed as the value at Week 24 minus the baseline value. A positive value in change from Baseline indicates an improvement and a negative value indicates worsening.	Week 24
