Primaire uitkomstmaten
Primary endpoint consists of a composite endpoint concerning meaningful improvement across 2 or 3 Sjögren’s syndrome disease domains: oral, ocular and laboratory test
Achtergrond van het onderzoek
Design:
An open, proof-of-concept, investigator initiated study
Subjects:
Female postmenopausal patients with primary Sjögren’s syndrome and complaints; no contraindications for estrogens especially no increased risk and/or history of thrombo-embolic events
Study Medication:
Estetrol, dose of 20 mg per day during 28 days.
Treatment regimen:
first 4 weeks run-in period with placebo, thereafter 4 weeks treatment with estetrol, followed by 14 days treatment with a progestogen.
Clinical phase:
Phase II (proof-of-concept)
Primary objective:
To explore overall response to treatment with estetrol in patients with primary Sjögren’s syndrome.
Secondary objectives:
To assess:
· improvement in quantitative levels of SSA and/or SSB
· decrease in pilocarpine use during treatment.
· improvement in results of the SF36
· safety of estetrol treatment.
Primary Endpoints:
Primary endpoint consists of a composite endpoint concerning meaningful improvement across 2 of 3 Sjögren’s syndrome disease domains: oral, ocular, and laboratory tests.
· Oral improvement will be defined as ≥20% in the patient’s assessment of dry eyes (on a 100 mm VAS) or ≥20% improvement in total unstimulated salivary flow.
· Ocular improvement will be defined as ≥20% improvement in either the patient’s assessment of dry eyes by VAS or the results of the Schirmer’s test without anaesthetic.
· Laboratory improvement will be defined as ≥20% improvement in the serum IgG or the ESR.
