Percentage of Participants With a Clinically Relevant Decrease in European League Against Rheumatism (EULAR) Sjogren's Syndrome Disease Activity Index (ESSDAI) Score
Percentage of participants with a clinically relevant decrease in European League Against Rheumatism (EULAR) Sjogren's Syndrome Disease Activity Index (ESSDAI) Score is defined as participants with absolute decrease of ≥ 3-points in ESSDAI score. ESSDAI is physician-assessed disease activity index developed by EULAR consortium consisting of 44 items in 12 organ-specific 'domains' (constitutional,lymphadenopathy, articular,muscular,cutaneous,glandular,pulmonary,renal,peripheral nervous system,central nervous system,hematological,biological). Each domain is assessed for activity level (i.e., no, low, moderate, high) and assigned a numerical score based on pre-determined weighting of each individual domain. Overall score is calculated as sum of all individual weighted domain scores (ranges from 0 (best) to 123 (worst activity). A score ≥ 5 is considered moderate or severe disease activity and a clinically relevant change in ESSDAI score is defined as absolute decrease of ≥ 3-points.
Time frame: 12 weeks
Percentage of Participants With a Clinically Relevant Decrease in EULAR Sjogren's Syndrome Patient-Reported Index (ESSPRI) Score
The efficacy of RO5459072 in patients with primary Sjogren's Syndrome Disease is evaluated in terms of the percentage of participants with a clinically relevant decrease in EULAR Sjogren's Syndrome Patient-Reported Index (ESSPRI) Score, where a clinically relevant decrease in ESSPRI score is defined as a decrease of ≥ 1 point. The ESSPRI is a patient-reported, subjective symptom index for primary Sjögren's syndrome developed by the EULAR consortium. It consists of 3 questions covering cardinal symptoms of Sjögren's syndrome: dryness, fatigue and pain (articular and/or muscular). Each domain scored on scale of 0-10 (0 =no symptom at all and 10 = worst symptom imaginable), and overall score is calculated as the mean of 3 individual domains where all domains carry same weight.
Time frame: 12 weeks
Change From Baseline in ESSDAI Score at Week 12
Change from baseline in European League Against Rheumatism (EULAR) Sjogren's Syndrome Disease Activity Index (ESSDAI) Score is defined as the change in score between baseline (Week -1) and Week 12. The ESSDAI is a physician-assessed disease activity index for primary Sjögren's syndrome developed by the EULAR consortium. It consists of 44 items in 12 organ-specific 'domains' contributing to disease activity (constitutional, lymphadenopathy, articular, muscular, cutaneous, glandular, pulmonary, renal, peripheral nervous system, central nervous system, hematological, biological). Each domain is assessed for activity level (i.e., no, low, moderate, high) and assigned a numerical score based on pre-determined weighting of each individual domain. An overall score is then calculated as the sum of all individual weighted domain scores. Overall score is calculated as sum of all individual weighted domain scores (ranges from 0 (best) to 123 (worst activity).

Change From Baseline in Short Form 36 Health Survey (SF-36) Mental Score at Week 12
Change from baseline in Short Form-36 Health Survey (SF-36) Mental score is defined as the change in score between baseline (Week -1) and Week 12. The SF-36 was used to assess health-related quality of life at baseline and at on-treatment visits. The SF-36 consisted of 36 questions covering 8 domains (general health, physical functioning, role-functioning physical, bodily pain, social functioning, role-functioning emotional, mental health, and vitality), with each domain scoring on a scale 0-100 (a score of 0 = maximum disability and a score of 100 = no disability). Reported here is the mental health domain score.

Change From Baseline in Tear Flow Rate at Weeks 2, 6, and 12
Un-stimulated tear production rate was measured from both eyes (without the use of analgesics/ anesthetic drops) at baseline and at on-treatment visits using the Schirmer method. A thin strip of filter paper (Schirmer strip, e.g., 35 x 5 mm) was placed at the junction of the lateral and middle thirds of the lower eyelid of each eye. The maximum length of wetting along the strip at the end of the test period was measured.

Percentage of Participants With Adverse Events
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Time frame: Baseline up to Week 14
