Clinical Trial Summary

Objectives:

The study will assess the ocular hypotensive effect of latanoprost and dorzolamide in a selected sample of patients affected by primary Pediatric Glaucoma (PG), refractory to surgical procedures. Safety will be assessed, too.In the first version of the protocol 96 eyes were forecasted to complete the enrolment. The protocol was then amended and now to complete the study 68 eyes should be included. This number of eyes could be achieved by recruiting from 34 to 68 patients due to not in all patients both eyes should be eligible for the study.


Description:

Study design:

Single arm, prospective, experimental study. Due to ethical reasons and in order to adhere as much as possible to current clinical practice, the presence of a control arm is not planned. Due to the non-comparative nature of the study, no blinding of treatment is planned.

- Children of either sexes, aged 0-12 years

- Diagnosis of mono- or bilateral primary congenital glaucoma

- IOP greater than or equal to 22 mmHg and lower than 27 mmHg

- Only one previous ocular hypotensive surgical procedure for treatment of glaucoma among the following: goniotomy, trabeculotomy, trabeculotomy with adjunct of mitomycin C) (only for medical treatment at least one month before)

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Eyes With Response defined as those eyes in which the decrease of intraocular pressure (IOP) of at least 20% with respect to baseline assessment will be achieved and maintained during the 3-year period of study duration 3 years
Secondary Time to Treatment Failure (TTF) calculated as the time from the date of baseline visit to the date in which the medical treatment will be stopped, since IOP control will be considered not satisfactory 3 years
Secondary Number of Eyes With an Adverse Event (AE) The occurrence of the following events will be monitored: growth of the eyelashes (hypertrichosis), changes iris colour, corneal epitheliopathy, allergic conjunctivitis, increase of central corneal thickness, non-serious and serious adverse event occurrence. 3 years
