Eye drops combining an added medicinal ingredient with hyaluronic acid 0.3% versus hyaluronic acid 0.3% alone for moderate-to-severe dry eye

Interventional, Multi-center, Randomized, Controlled, Open Label Clinical Investigation Between the Topical Administration of a Tear Substitute Containing Ancillary Medicinal Substance and Hyaluronic Acid 0.3% (FBV_01) Versus Hyaluronic Acid 0.3% in Subjects in the Treatment From Moderate to Severe Dry Eye Syndrome

NA · FB Vision S.p.A · NCT07412860

We will test whether eye drops that combine an additional medicinal ingredient with hyaluronic acid 0.3% help adults with moderate-to-severe dry eye as well as or better than hyaluronic acid 0.3% alone.

What this trial studies

Adults with moderate-to-severe dry eye will be randomly assigned to receive an ophthalmic solution containing an ancillary medicinal substance plus hyaluronic acid 0.3% (FBV_01) or hyaluronic acid 0.3% alone. The trial will compare clinical performance measures (symptom scores and tear-film tests such as SANDE, tear break-up time, and Schirmer), as well as tolerability, safety, and participant compliance over the treatment period. Investigators will collect objective signs and participant-reported symptoms at scheduled visits at participating ophthalmology centers in Italy. The goal is to determine whether the combination product provides at least equivalent clinical benefit without an increase in adverse effects.

Who should consider this trial

Good fit: Adults aged 18 or older with a documented diagnosis of moderate-to-severe dry eye for at least six months who meet objective criteria (SANDE > 60, tear break-up time < 7 seconds, Schirmer < 10 mm) are the intended participants.

Not a fit: People with only mild dry eye, active ocular infection, known intolerance to the drop components, or other eye conditions that drive symptoms unrelated to tear-film deficiency are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the combined formulation could provide equal or better symptom relief and tear-film stability than standard hyaluronic acid drops without added safety concerns.

How similar studies have performed: Hyaluronic acid eye drops are an established treatment for dry eye, while formulations that add ancillary medicinal substances have been tested in some smaller studies with mixed or preliminary results.

Eligibility criteria

* Patient able to cooperate with the Investigator and meet the requirements of the clinical investigation plan;
* Patient who, in the opinion of the Investigator, will benefit from this treatment;
* Patient available for the entire study period.

Exclusion Criteria:

* Eye infection or clinically significant inflammation in both eyes (for example: Herpes simplex infections, corneal virus infections, bacterial, viral or fungal conjunctivitis, tuberculosis and mycosis of the eye, purulent and herpetic blepharitis, stye);
* History or evidence of eyelid abnormalities in either eye;
* Use of topical cyclosporine, topical corticosteroids, or any other topical medication for the treatment of ocular pathologies in either eye within 7 days of study enrollment;
* Patients being treated with chronic systemic therapies with analgesic, anti-inflammatory, corticosteroids, or opioids;
* History of ocular surgery (including laser procedures or refractive surgery) in either eye 7 days prior to enrollment;
* History or evidence of severe or uncontrolled systemic or autoimmune disease does not allow participation in the study or could impair the results;
* Patients being treated with drugs and/or medical devices and/or supplements for neuropathic pain (e.g., SNRIs (duloxetine, venlafaxine), pregabalin, gabapentin, TCAs (nortriptyline, amitriptyline));
* Patient with known or potential allergy or hypersensitivity and/or history of allergic reactions to one of the components of the medical device;
* Participation in another clinical trial within 30 days prior to the screening visit;
* History of administration or abuse of drugs, medications, or alcohol;
* Women of childbearing potential (those who are not surgically sterilized or post-menopausal for at least 1 year) will be excluded from participation in the study if they meet any of the following conditions:

  1. are currently pregnant or,
  2. have a positive urine pregnancy test result at visit 1,
  3. intend to become pregnant during the study treatment period or,
  4. are breastfeeding or, unwilling to resort to highly effective birth control measures, such as: hormonal contraceptives oral, implanted, transdermal or injected and/or mechanical barrier methods spermicidal concurrently with a barrier such as a condom or diaphragm or IUD during the entire course of the study and 30 days after the end of the treatment period;
* Subject unable to follow clinical investigation procedures and follow-up visits;
* Any other medical condition which, in the opinion of the Investigator, could influence participation in the clinical investigation or compromise its results.
