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.

The Modified Intent-to-Treat population included all randomized subjects who received at least one dose of either baminercept or placebo with screening and post-screening stimulated salivary flow results. Participants missing Week 24 assessment were imputed from last post-screening assessment. Salivary flow results unavailable for one subject.

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.

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.

The Modified Intent-to-Treat with available data population included all randomized subjects who received at least one dose of either baminercept or placebo and who had an ESSDAI score at Baseline and Week 24. Data were not available for five participants who received baminercept and two participants who received placebo.

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.

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.

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.

Grades are based on National Cancer Institute--Common Terminology Criteria (NCI-CTCAE) Version 4.0 over the duration of the study. Participants who experienced at least one grade 3 or higher adverse event (AE) are counted only once. The adverse events are treatment-emergent, which means that the AE occurred after taking the first dose of study drug.

The Safety population included all randomized subjects who received at least one dose of either baminercept or placebo.
