Outcome Measures
Primary Outcomes (2)
Number of Patients Reaching a Value of Schirmer I Test (Without Anaesthesia) >10mm/5min at Week 4
The Schirmer test type I (without anaesthesia) was performed to measure aqueous tear secretion. The rounded bend end of a sterile strip was inserted into the lower conjunctival sac over the temporal one-third of the lower eyelid margin. 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). The longer the wetted length, the healthier the status of the eye.
at week 4
Change From Baseline in Symptoms Questionnaire (SANDE) Global Score at Week 12
The SANDE questionnaire is comprised of two questions: 1) How often do your eyes feel dry and/or irritated? And 2) How severe you feel your symptoms of dryness and/or irritation are? The SANDE questionnaire uses a 100 mm horizontal line for each question to assess the extent of patients' symptoms. In this questionnaire, frequency of symptoms ranges from "rarely" (0) to "all of the time" (100) and the severity of symptoms ranges from "very mild" (0) to "very severe" (100). At each visit, patients were asked to place a mark on the two given lines based on the extent of their symptoms. The locations of the marks made by the patients on the 100 mm horizontal lines were measured in mm from left to right. The global SANDE score is calculated by multiplying the frequency score by the severity score and obtaining the square root. Both for total score and for frequency or severity scores, 0 is the best condition, 100 the worst condition. Please note that adjusted means are reported.

Study Arms (2)
Oxervate
EXPERIMENTALOne drop of cenegermin 20 mcg/mL (rhNGF 20 mcg/mL) in the pharmaceutical form of ophthalmic sterile solution was instilled in both eyes three times daily (TID), every six hours.
Vehicle
PLACEBO COMPARATOROne drop of vehicle ophthalmic solution was instilled in both eyes TID (every six hours).
Interventions
Oxervate®, an ophthalmic solution containing cenegermin 20 mcg/mL, which is a recombinant human Nerve Growth Factor (rhNGF); one drop of the test product will be instilled in both eyes three times daily (TID).
Vehicle will be instilled with the same scheme of the test product
