About this study

The HANITA Glaucoma Filtration Device is intended to reduce intraocular pressure in glaucoma patients where medical and conventional surgical treatments have failed.

Read the detailed description

Study Design:

This study is a prospective, single-arm single-center, open-label study.

Study population:

Men and women diagnosed with open-angle glaucoma who require glaucoma surgery procedures that meet the inclusion/exclusion criteria and provide written informed consent will be enrolled in the study.

Enrollment:

A total of 30 subjects will be enrolled:

15 patients will be implanted according to procedure 1 (see section 8.7), at completion additional 15 patients will be implanted according to procedure 2 (see section 8.7)

Investigational sites:

One (1) center will participate in this study.

Duration of Subject participation:

Completion of active enrolment is anticipated to last approximately 6 months. The primary endpoint will be achieved when the final study subject has completed 6 months follow-up.

Study Group:

A single study group. This is a single-arm design; there is no control device in this study.

Visits \& Procedures Pre-operative visit: 0-3 months prior to the implantation procedure. The visit will include the subject's qualification assessment for inclusion/exclusion criteria as described above. Informed consent must be signed.

Complete anamnesis will be taken including the subject's medical complaints, medical history, and medication use. Ophthalmic examinations as well as ultrasound biomicroscopy.

Surgical procedure: Procedure will be performed under anesthesia (at physician discretion) and a Hanita shunt will be implanted.

Follow-up: All subjects will have regular follow-up visits at 1 and 7 days and on 1, 3, and 6 months post-implantation. 1-year post-operative evaluation is optional at the sponsor's discretion. All postoperative visits will include a complete ophthalmic examination,

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. VISUAL ACUITY

    • Distance (far) manifest refraction and the testing distance used will be recorded on the case report forms. Manifest refraction will be determined using the maximum plus for best visual acuity method. The distance manifest refraction will be done with a distance adjusted chart but not less than 4 meters. The actual manifest refraction distance will be noted on the case report forms.

    Visual acuity will be measured with ETDRS format charts for distance and near. Results will be recorded in a LogMar scale.

    Measured: 1 year

  2. SLIT LAMP EXAM

    The slit lamp exam will include the measurement of aqueous cell and flare, and the measurement of corneal edema by a standard grading system. It will also include an evaluation for the presence of pupillary irregularities, iris atrophy and pigment dispersion. A gonioscopic exam using a consistent grading system at each site will also be conducted.

    For the evaluation of aqueous cells and flare, use a slit lamp beam 0.3 mm wide and 1 mm high, and use the following grading:

    Cells none (0) = no cells seen trace (+1) = 1-5 cells seen mild (+2) = 6-15 cells seen moderate (+3) = 16-30 cells seen severe (+4) = > 30 cells seen

    Flare none (0) = No Tyndall effect trace (+1) = Tyndall effect barely discernible mild (+2) = Tyndall beam in anterior chamber is mildly intense moderate (+3) = Tyndall beam in anterior chamber is moderately intense severe (+4) = Tyndall beam is severely intense. The aqueous has a white and milky appearance.

    Measured: 1 year

  3. MEASUREMENT OF INTRAOCULAR PRESSURE

    Intraocular pressure will be measured using Goldmann applanation tonometry or other validated methods.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Hanita Glaucoma shunt Ver.3.2 in people with Glaucoma, run by Hanita Lenses at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

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?

VISUAL ACUITY (time frame: 1 year). The study lists 3 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 2 Mar 2022.
