Scientific title


Study hypothesis

To assess the efficacy and safety of SVS20 versus saline (as a basic standard reference product) and carbomer (as a standard treatment with a marketing authorisation in most EU countries) in patients with bilateral moderate dry eye syndrome due to Sjogren's syndrome (immune exocrinopathy) or diagnosed as a primary syndrome.

Please note that the results of this study were used to calculate the sample size of a more recent phase III multicentre study conducted in France and UK. For more details on this phase III study, please visit the ISRCTN record at

Ethics approval

Ethics approval received from:
1. The National Ethics Committee for Clinical Pharmacology (KFEB) on the 29th June 2005
2. The Ministry of Health on the 14th July 2005

Thereafter, local Institutional Review Board (IRB) at each centre gave favourable opinions on 13 September 2005 (Dr. Deák), 5 October 2005 (Dr. Sohajda), 18 October 2005 (Dr. Márta), 21 November 2005 (Dr. Zeher) and 2 December 2005 (Dr. Bereczki).

Patient information sheet


Dry eye syndrome


There were three arms:
1. SVS20
2. Saline
3. Carbomer

Patients instilled 2 - 4 times a day one of these eye drops. Treatment duration was 1 month with a previous period of wash-out of 112 to 16 days.

The following parameters were measured at V1 (day 16 to day 12), V2 (day 0) and V3 (day 28):
1. BUT
2. Schirmer I test
3. Lissamine and fluorescein staining
5. Slit lamp examination
6. Symptoms intensity and frequency

Intervention type



Phase II

Drug names

SVS20, carbomer

Primary outcome measure

Since this study was a phase II there were no primary or secondary outcomes. Our aim was to analyse the efficacy and safety of SVS20 versus saline and carbomer and to find a parameter that could be used as the primary criterion for the following pivotal phase III study (ISRCTN91412460). Therefore, the following parameters were assessed:
1. Efficacy and tolerability:
1.1. Number of instillations
1.2. Staining with lissamine green
1.3. Symptom intensity and frequency
1.4. Repercussion of symptoms on activities of daily life
1.5. Comfort of the eye drops (presence and duration of blurred vision after instillation)
1.6. Slit lamp examination
1.7. Tear volume (Schirmer I test)
1.8. Tear film BUT
1.9. Corneal staining with fluorescein
1.10. Global evaluation of efficacy

2. Safety:
2.1. Comfort of the eye drops (presence and duration of blurred vision)
2.2. BCVA
2.3. Impairment of dry eye symptoms
2.4. Ocular adnexa examination
2.5. Adverse events reporting

Parameters were measured at V1 (Day-16 to Day-12), V2 (Day 0) and V3 (Day 28).

Secondary outcome measures
