详细描述
This was a 4 week phase III, multicenter, double-masked, vehicle-controlled study to evaluate safety and efficacy of cenegermin ophthalmic solution at 20 mcg/mL solution versus vehicle, in patients with severe Sjogren's dry eye disease under treatment with Ciclosporine A (or other drugs of the same class).
During the Screening all procedures for inclusion and exclusion were performed. From the day of screening, the patients stopped any kind of further treatment, except CsA and commercially available preservative-free artificial tears provided by the Sponsor for a period of 8 days and 10 days as maximum. At the end of the washout period, patients still meeting the entry criteria for this study were randomized 1:1 and treated for 4 weeks with either cenegermin ophthalmic solution 20 mcg/mL three times a day (TID) or vehicle TID.
In addition to topical CsA eye drops (both groups continued with topical CsA eye drops, or other topical ophthalmic treatment of the same class), during the 4 weeks of masked treatment, only the administration of investigational medicinal product (IMP) was allowed.
During the follow up period, the patient could administer additional preservative-free artificial tear eye drops, provided by the Sponsor, only if strictly needed, and had to document in the patient's Diary the number of additional drops administered for each eye.
Patients were then followed-up for efficacy and safety endpoints until Week 16 and for safety endpoints until Week 24.

盲法说明
This was a double-blind study.The vials containing cenegermin (20 mcg/mL) or vehicle were identical in appearance, and the contents of the vials were indistinguishable. All staff directly involved in the analysis of study results remained masked to treatment assignments while the study was in progress. The blind was not broken for any patient during the study before the database lock.

结局指标
主要结局
Number of Patients With Schirmer I Test (Without Anesthesia) >10mm/5min in the Eligible Eye at Week 4
时间窗: At Week 4 (Visit 3)
The Schirmer test was used in ophthalmic examination to measure tear production for the diagnosis of conditions such as keratoconjunctivitis sicca and dry eye. Without previously instilling anesthetic drops, the Schirmer strip was inserted into the lower conjunctival sac at the junction of the lateral and middle thirds, avoiding touching the cornea, and the length of wetting strips in millimeters was recorded after 5 minutes. After 5 minutes had elapsed, the Schirmer's test strip was removed and the length of the tear absorption on the strip was measured (millimeters/5 minutes). Cutoff values: \<5 mm - pathologic dry eye 5-10 mm - marginal dry eye \>10 and \<30 mm - normal secretion The longer, the wetted length, the healthier the status of the eye. No units other than participants were assigned.
Change From Baseline in Symptom Questionnaire (SANDE) Global Score at Week 12
时间窗: At Week 12 (Visit 5 - Follow up)
SANDE was a short questionnaire to evaluate both dry eye intensity and frequency. It uses a 100 mm horizontal line (Visual Analogue Scale - VAS), for each of the 2 questions, to assess ocular discomfort and/or dryness. Frequency of symptoms ranged from "rarely" (best outcome) to "all of the time" (worst outcome), while the severity of symptoms ranged from "very mild" (best outcome) to "very severe" (worst outcome). Patients had to place a mark on the two given lines based on the extent of their symptoms. The locations of the marks was measured in mm from left to right and recorded as frequency and severity scores, respectively. The SANDE lines for intensity and for severity ranged from 0, being the minimal amount of dry eye symptoms (best outcome) to 100, being the maximal amount of dry eye symptoms (worst outcome). The total SANDE score was calculated by multiplying the frequency score by the severity score and obtaining the square root (0-100; the lower, the better).
