E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Dry Eye syndrome is caused by either decreased tear production or increased tear film evaporation. Dry eye is a chronic inflammatory condition of the ocular surface with severe symptoms and visual impairment, leading to worse efficiency to perform duties |
|
E.1.1.1 | Medical condition in easily understood language |
Dry eyes occur when your tears aren't able to provide adequate moisture for your eyes. Tears can be inadequate for many reasons. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess the efficacy and safety of different doses of rhNGF when administered as eye drops to patients with Dry Eye. on the basis of the following assessments: - Symptom Assessment in Dry Eye (SANDE) - Ocular surface vital staining (National Eye Institute [NEI] scales) - Schirmer test type I (without anaesthesia) performed on days 1, 8±1, 29±1 and 56±4. Changes from baseline (screening visit) will be evaluated. - Treatment-emergent adverse events (TEAEs), assessed throughout the study |
|
E.2.2 | Secondary objectives of the trial |
Evaluation of the clinical efficacy and safety during and at the end of treatment with rhNGF, on the basis of the following assessments: - Visual analogue scale (VAS) for (foreign body sensation, burning/stinging, itching, pain, stick feeling, blurred vision and photophobia) - Slit lamp examination (Eyelid - Meibomian glands, Eyelid – Erythema, Eyelid - Oedema Lashes, Conjunctiva Erythema, Lens, Iris, Anterior Chamber) - Schirmer test type II (with anaesthesia) - Tear Film Break-Up Time (TFBUT) - Corneal sensitivity (Cochet-Bonnet aesthesiometry) - Intraocular Pressure (IOP) - Ocular Surface Disease Index (OSDI) - Visual acuity - Fundus ophthalmoscopy - Tear Film osmolarity - Conjunctival impression cytology for goblet cells' count - Frequency of artificial tears use performed on days 1, 8±1, 29±1 and 56±4. Changes from baseline (screening visit) will be evaluated. - Vitals signs, body weight (BW), physical examinations. |

Any active ocular infection or active inflammation in either eye unrelated to Dry Eye; 7. Presence or history of any systemic or ocular disorder, condition or disease that could possibly interfere with the conduct of the required study procedures or the interpretation of the study results; 8. Use of therapeutic or Refractive Contact lenses in either eye within 30 days of study enrolment; 9. History of ocular surgery in the study eye, including corneal refractive procedures, within 90 days of study enrolment; 10. Females of childbearing potential (those who are not surgically sterilized or post-menopausal for at least 1 year) are excluded from participation in the study if they meet any one of the following conditions: a. are currently pregnant or, b. have a positive result at the urine pregnancy test (screening/Day 1) or, c. intend to become pregnant during the study treatment period or, d. are breast-feeding or, e. are not willing to use highly effective birth control measures, such as: hormonal contraceptives - oral, implanted, transdermal, or injected - and/or mechanical barrier methods - spermicide in conjunction with a barrier such as a condom or diaphragm or IUD - during the entire course of and 30 days after the study treatment periods. 11. Participation in another clinical study at the same time as the present and within 30 days of study enrolment; 12. History of drug, medication or alcohol abuse or addiction. |
