Official title: Evaluation of the Efficacy and Safety of Eye Drops With Hyaluronic Acid Sodium Salt 0.30% and Amino Acid (BLUgel A Free) in Patients With Moderate to Severe Dry Eye Syndrome and Hyaluronic Acid Sodium Salt 0.15% and Amino Acid (BLUyal A Free) in Patients With Mild Dry Eye Syndrome
This is a profit, multicentric, prospective, open-label, non-pharmacological clinical investigation aim to evaluate the efficacy and tollerability of two types of eye drops containing Hyaluronic acid (HA) with different concentration as 0.30% (BLUgel A) and 0.15% (BLUyal A). the study will consider patients affected by moderate to severe dry eye syndrome which will be treated with HA 0.30% while patients affected by mild dry eye syndrome will be treated with HA 0.15%.Dry eye syndrome (DES) is defined as a multifactorial disease of the ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface.Based on the available background on the use of HA in the management of DES, this investigation has been designed to assess the efficacy of HA- and amino acid-based product BLUgel A free and BLUyal A free, in patients with moderate to severe and mild dry eye syndrome, respectively.
Read the detailed description
This is a profit, multicentric, prospective, open-label, non-pharmacological clinical investigation. Patients will have an initial screening/baseline Visit 1-T0 (day 0). Patients with diagnosis of moderate to severe dry eye syndrome will start a 60 days treatment period with BLUgel A free (2 drops per eye, 3 times a day, bilaterally), while patients with diagnosis of mild dry eye syndrome will start a 60 days treatment period with BLUyal A free (2 drops per eye, 3 times a day, bilaterally).
The following on-site visits will be performed: Visit 2-T1 (day 15 [+3]), Visit 3-T2 (day 30 [+3]) and Visit 4-T3 (day 60 [+3]). Visit 3-T2 and Visit 4-T3 should be performed preferably at day 30 and day 60 respectively. In case Visit 3-T2 is postponed within the allowed window, treatment has to be continued by the patient without interruption.
A total of 100 male or female patients who have been diagnosed with mild or moderate to severe dry eye syndrome are planned to be enrolled. Dry eye syndrome will be classified according to Tear Film and Ocular Surface Society (TFOS) Dry Eye Workshop (DEWS) (2007 version) definition. Patients with diagnosis of moderate to severe dry eye syndrome will be treated with BLUgel A free for 60 days, patients with diagnosis of mild dry eye syndrome will be treated BLUyal A free for 60 days. Patients will be stratified in the two categories of severity, i.e. 50 patients with moderate/severe dry eye syndrome treated with BLUgel A free and 50 patients with mild dry eye syndrome treated with BLUyal A free.
Patients are not permitted to use a concomitant drug or device interfering with the dryness of the eye, such as corticosteroid and antibiotic eye drops; instead, they are permitted to use any drug or device non-interfering with the treatment of dry eye syndrome and not affecting the effectiveness of BLUgel A free or BLUyal A free or the occurrence of adverse reactions.

Efficacy Assessment from baseline in patients with moderate to severe dry eye syndrome
Change from baseline (T0) to Day 60 (T3) of overall score of NEI corneal (range 0-15) and conjunctival fluorescein (range 0-18) staining following treatment with BLUgel A free, and change from baseline (T0) to Day 30 (T2) and Day 60 (T3) of overall score of NEI corneal and conjunctival fluorescein staining following treatment with BLUyal A free ophthalmic solution. the maximum score of the sum of NEI corneal and conjunctival total score is 33.
Measured: Day 60
Efficacy Assessment from baseline
- Changes from baseline (T0) to Day 30 (T2) and Day 60 (T3) in Tear Film Break-Up Time (TFBUT) values, following treatment with BLUgel A free ophthalmic solution in patients with mild dry eye syndrome.
- Changes from baseline (T0) to Day 60 (T3) in Tear Film Break-Up Time (TFBUT) values, following treatment with BLUyal A free ophthalmic solution in patients with mild dry eye syndrome.
The TFBUT will be measured twice during the first minute after the instillation of the fluorescein. If the 2 readings differ by more than 2 seconds a third reading will be taken. The TFBUT value will be the average of the 2 or 3 measurements.
Measured: Day 30 and Day 60
Efficacy Assessment from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in non-invasive Break-Up Time (niBUT) measured via Tearcheck®, following treatment with BLUgel A free, and with BLUyal A free ophthalmic solution. niBUT evaluates the stability and the break-up time of the tear film. In particular, niBUT shows site and time of ruptures of the tear film. During a 10-second imaging, Tearcheck® evaluates the tear film surface 3 times per second. For better readability, results are then grouped into 2-second increments. niBUT will be expressed in seconds.
Measured: Day 30 and Day 60
Change in non-invasive Break-Up Time (niBUT) from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in non-invasive Break-Up Time (niBUT) measured via Tearcheck®, following treatment with BLUgel A free, and with BLUyal A free ophthalmic solution. niBUT evaluates the stability and the break-up time of the tear film. In particular, niBUT shows site and time of ruptures of the tear film. During a 10-second imaging, Tearcheck® evaluates the tear film surface 3 times per second. For better readability, results are then grouped into 2-second increments. niBUT will be expressed in seconds.
Measured: Day 30 and Day 60
Assessment of Tear meniscus height after treatment compared to baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) of conjunctival, measured via Tearcheck®, following treatment with BLUgel A free and with BLUyal A free ophthalmic solution.
The Tearcheck® instrument will be used to measure niBUT, tear meniscus height, conjunctival hyperaemia and meibography, which will not be performed at Visit 2-T1 (Day 15 +3); all the remaining parameters will be measured at any visit.
The tear meniscus will be evaluated in the lower eyelid and shows, if there is sufficient tear production before the next eye blink. Two values will be calculated: 1) tear meniscus measurement below iric centre; 2) thickest measurement of the tear meniscus. The tear meniscus height will be expressed in millimetres.
Measured: Day 30 and Day 60
Assessment of conjunctival hypaermia from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in conjunctival hypaermia, measured via Tearcheck®, following treatment with BLUgel A free and with BLUyal A free ophthalmic solution. niBUT evaluates the stability and the break-up time of the tear film.The Tearcheck® instrument will be used to measure niBUT, tear meniscus height, conjunctival hyperaemia and meibography, which will not be performed at Visit 2-T1 (Day 15 +3); all the remaining parameters will be measured at any visit.
Measured: Day 30 and Day 60
Assessment of possible changes in meibomian gland from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in meibography, measured via Tearcheck®, following treatment with BLUgel A free and with BLUyal A free ophthalmic solution. Meibography makes it possible to visualize the meibomian glands. This visualization is useful in explaining the anatomical structure responsible for the production of the lipid film to the patient. The result will be expressed as percentage of loss of glands compared to an individual with all of the glands present.
Measured: Day 30 and Day 60
Assessment of total tear secretion from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in Schirmer's Test I values following treatment with BLUgel A free and with BLUyal A free ophthalmic solution.
The Schirmer's test I (Schirmer, 1903) measures the quantity of total tear secretion, including reflex and basal tears, which are produced by the eye. A 35 mm x 5 mm size filter paper strip is used to measure the amount of tears that are produced over a period of 5 minutes. Without instilling anaesthetic drops, the Schirmer strips are inserted into the eye under the eyelid and into the lower conjunctival fornix near the lateral corner, avoiding contact with the cornea. The paper strip remains in the conjunctival fornix for 5 minutes to measure the production of tears. The wet portion of the strip is measured in millimetres. The test is done under ambient light. The patient is instructed to look forward and to blink normally during the course of the test.
Measured: Day 30 and Day 60
Assessment of impact of Dry Eye on Everyday Life (IDEEL) from baseline
Change from baseline (T0) to Day 30 (T2) and Day 60 (T3) in score of Impact of Dry Eye on Everyday Living (IDEEL) questionnaire ("Dry Eye Symptom-Bother" module) following treatment with BLUgel A free and with BLUyal A freeophthalmic solution. The Impact of Dry Eye on Everyday Life (IDEEL) questionnaire is a comprehensive dry eye specific questionnaire developed to evaluate symptom-related bother, impact on daily life and treatment satisfaction in a population with dry eye (Abetz et al, 2011). There are 57 items grouped into 3 different modules: i) the Dry Eye Impact on Daily Life" (3 section: daily living activities (9 items), emotional impact (12 items) and impact of work (6 items); ii) the "Dry Eye Symptom-Bother" (20 items), and iii) the "Dry Eye Treatment Satisfaction" (10 items). Only the "Dry Eye Symptom-Bother" (10 items) will be evaluated in this investigation
Measured: Day 30 and Day 60
Incidence and nature of treatment-emergent adverse events
Incidence and nature of treatment-emergent adverse events (TEAEs) as well as of the treatment-emergent serious adverse events (TESAEs); Incidence and nature of the Adverse Device Effects (ADEs); Incidence and nature of the Serious Adverse Device Effects (SADEs); Incidence and nature of Investigational Medical Device Deficiencies (IMDDs)
Measured: Day 30 and Day 60

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Efficacy Assessment from baseline (time frame: Day 30). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
