Intervention model description: profit, multicentric, prospective, open-label, non-pharmacological clinical investigation
Primary purpose: TREATMENT

Brief summary: 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.

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.

Eligibility criteria: Inclusion Criteria:

Patients who meet all the following criteria at the screening/baseline visit will be considered as eligible for the investigation:

1. Patients having signed written informed consent to participate in the investigation obtained according to Good Clinical Practice (GCP);
2. Patients having an age ≥ 18 years;
3. Patients with diagnosis of dry eye syndrome (according to Tear Film and Ocular Surface Society \[TFOS\] Dry Eye Workshop \[DEWS\] definition);
4. Diagnosis of dry eye syndrome for the investigation assessed through at least the following exams: slit lamp examination (SLE), tear (lacrimal) meniscus exam, Schirmer's test I, TFBUT, cornea and conjunctiva staining, IDEEL questionnaire ("Dry Eye Symptom-Bother" module); 4a) Diagnosis of mild dry eye syndrome will be based on the following criteria:

   * TFBUT 7-10 sec
   * Schirmer's test I 7-10 mm
   * Fluorescein staining of the cornea and conjunctiva (NEI scale value) \<7
   * IDEEL questionnaire ("Dry Eye Symptom-Bother" module) score 40-50
   * Patient not treated in the previous 15 days for dry eye syndrome 4b) Diagnosis of moderate to severe dry eye syndrome will be based on the following criteria:
   * TFBUT \< 7 sec
   * Schirmer's test I \< 7 mm
   * Fluorescein staining of the cornea and conjunctiva (NEI scale value) ≥7
   * IDEEL questionnaire ("Dry Eye Symptom-Bother" module) score \>50
   * Dry eye syndrome treatment permitted; no ophthalmic gel treatment permitted

   In case of bilateral dry eye syndrome, both eyes will be treated but only the worst eye, defined as the eye with the higher severity of impairment according to the Investigator's judgment based on the above exams, will be considered for assessments (although both eyes will be treated). In the case of bilateral dry eye syndrome with both eyes having the same level of impairment, the right eye will be considered for assessments by convention; In case of monolateral dry eye syndrome, both eyes will be treated. Evaluations of both the eyes will be collected but only target eye evaluations will be used for statistical analysis.
5. Patients being able to comprehend the full nature and the purpose of the investigation, including possible risks and side effects, and patients able to cooperate with the Investigator and to comply with the requirements of the entire investigation (including ability to attend all the planned investigation visits according to the time limits), based on Investigator's judgment;
6. Female patients having a negative urine pregnancy test result at screening and using an appropriate method of contraception for at least 30 days before inclusion and during the whole investigation period, according to the definition of Note 3 of ICH M3 Guideline\*, if females of childbearing potential (i.e., not permanently sterilized - post hysterectomy or tubal ligation status - or not postmenopausal);

   * Note: According to the definition of Note 3 of ICH M3 Guideline a highly effective method is defined as those which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Highly effective birth control methods include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable); intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; sexual abstinence.

Patients who fulfil any of the following criteria at the screening/baseline visit will be excluded from the investigation:

1. Patients with mild dry eye syndrome that have used eye drops product in the 15 days preceding the screening/baseline visit.

   Patients with moderate to severe dry eye syndrome may have used treatment for dry eye syndrome in the 15 days preceding the screening/baseline visit, with the exception of gel compounds;
2. Patients under treatment with corticosteroids or antibiotics eye drops, hypotony-inducing products or any other therapy that, as per Investigator's opinion, could interfere with the assessment of the efficacy or incidence of adverse events;
3. Patients with presence or history of any systemic or ocular disorder, condition or disease (with particular attention to malignancies and neuro-oncological diseases) that, according to Investigator's judgment, can interfere with the conduct of the required investigation procedures or the assessment of the efficacy or the interpretation of the investigation results or the incidence of adverse events;
4. Patients with glaucoma;
5. Patients that use therapeutic or refractive contact lenses;
6. Patients with hypersensitivity and/or allergy to any of the BLUgel A free or BLUyal A free ingredients;
