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. The total duration of the study was 25 weeks including 1 week of screening.

Number of Patients With Schirmer I Test (Without Anesthesia) >10mm/5min in the Eligible Eye at Week 4
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.
Time frame: At Week 4 (Visit 3)
Change From Baseline in Symptom Questionnaire (SANDE) Global Score at Week 12
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).
Time frame: At Week 12 (Visit 5 - Follow up)
Key Secondary Outcome: Number of Patients With Schirmer I Test (Without Anesthesia) >10mm/5min at Week 8

Key Secondary Outcome: Change From Baseline in Symptom Assessment in Dry Eye Questionnaire (SANDE) Score for Severity at Week 12
The Symptom Assessment in Dry Eye (SANDE) questionnaire was a short questionnaire to evaluate both dry eye intensity/severity and frequency. This questionnaire used a 100 mm horizontal line (Visual Analogue Scale - VAS) for each of the 2 questions to assess ocular discomfort and/or dryness experienced by the patients. In the SANDE questionnaire, frequency of symptoms ranges from "rarely" to "all of the time" and the severity of symptoms ranged from "very mild" to "very severe". Patients were asked 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 scale 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). In this outcome severity score at week 12 was assessed.

Key Secondary Outcome: Change From Baseline in "Quality of Life, Dry Eye Treatment Satisfaction & Bother and Dry Eye Symptom-Bother" Modules Measured by "Impact of Dry Eye on Everyday Life [IDEEL]" Questionnaire at Week 12 and at Week 4.
IDEEL was a 57-item questionnaire that assessed the impact of dry eye symptoms on everyday life. It consisted of 3 modules: * Dry eye Quality of Life (27 items) composed by 3 dimensions: 1. Impact on Daily Activities 2. Emotional Impact 3. Impact on Work Scores for each dimension of this module ranged from 0 to 100, where higher scores indicated less impact on daily activities, on work and emotions. * Treatment Satisfaction \& Bother (8 items) composed by 2 dimensions: 1. Satisfaction with Treatment Effectiveness 2. Treatment-Related Bother / Inconvenience Scores for each dimension of this module range from 0 to 100, where higher scores indicate greater satisfaction with treatment effectiveness and less treatment-related bother. * Symptom Bother (20 items) composed by 1 dimension: 1. Dry Eye Symptom-Bother Scores for the dimension of this module ranged from 0 to 100, where higher scores indicated a greater symptom bother. No combination of dimensions scores was done.
Time frame: At Week 12 (Visit 5 - Follow-up) and Week 4 (Visit 3)
Key Secondary Outcome: Change From Baseline in Tear Film Break-Up Time (TFBUT) at Week 4, Week 8 and Week 12
Tear film break-up time (TFBUT) was the time taken to appear first dry spot on cornea after a complete blinking. TFBUT measurement was an easy and fast method used to assess the stability of tear film. It was a standard diagnostic procedure in the dry eye clinics. TFBUT was measured by determining the time to tear break-up. The TFBUT was performed after instillation of 5 μL of 2% preservative-free sodium fluorescein solution into the inferior conjunctival sac of each eye. The patient was instructed to blink several times to thoroughly mix the fluorescein with the tear film. A TFBUT greater than 15 seconds was considered normal, while a break time of less than 10 seconds was to be considered pathological. Hence, the shorter the time, the worse the outcome.
Time frame: At week 4 (Visit 3) , Week 8 (Visit 4), and Week 12 (Visit 5 - Follow-up)

Change From Baseline in Cornea and Conjunctiva Vital Staining With Fluorescein (National Eye Institute [NEI] Scales) at Week 4, Week 8, Week 12 and Week 16
The NEI/Industry Workshop guidelines were used for grading the scale of corneal and conjunctival damage. The cornea was divided into five sectors (central, superior, inferior, nasal and temporal), each of which was scored on a scale of 0-3, with a maximal total corneal staining score of 15. Both nasally and temporally, the conjunctiva was divided into a superior paralimbal area, an inferior paralimbal area, and a peripheral area with a grading scale of 0-3 and with a maximal total score of 9 for the nasal and temporal conjunctiva (overall the total score ranged from 0-18). Briefly, grade 0 reflected normal/healthy situation, whereas grade 3 reflected a severe damage in the considered sector.
Time frame: At Week 4 (Visit 3), Week 8 (Visit 4) , Week 12 (Visit 5) and Week 16 (Visit 6)

Number of Patients Experienced a Worsening in Symptom Scores (SANDE Global Scores) and/or NEI Score ≥ 50% at Week 4
Symptoms Scores (SANDE) and/or NEI Score were punctually described in the previous outcome descriptions. For Sande score, the scale ranges from 0 to 100 for both severity and frequency, where 0 was the best condition and 100 marked the worst condition. Hence the higher the score, the worse the outcome. For NEI score, the maximum score (worst outcome) was 15, and the minimum (best outcome) was 0; hence the higher the score, the worse the outcome. Please note that mean is an adjusted mean.
