About this study
Official title: An Open Two-center Study Evaluating the Safety of Hyaluronan Thiomer i.o. Implant During Combined Phacoemulsification - Non Penetrating Deep Sclerectomy in Patients With Open Angle Glaucoma and Cataract
The study is designed to assess the safety of Hyaluronan Thiomer i.o. implant in patients with primary open angle glaucoma undergoing a combined phacoemulsification - non penetrating deep sclerectomy procedure.
In this study, Hyaluronan Thiomer i.o. will be implanted during a combined surgery of cataract and non - penetrating deep sclerectomy in a group of 16 patients with primary open angle glaucoma and clinically significant cataract. Given that a considerable number of glaucoma patients also suffer from cataract, it is reasonable to test Hyaluronan Thiomer i.o. during a combined procedure of phacoemulsification and deep sclerectomy. This is also of importance because a combined procedure avoids the need of a second operation in this group of patients. Finally, it has been shown that combined phacoemulsification - deep sclerectomy does not induce a further risk compared to deep sclerectomy alone(open phase I study).

Safety will be assessed based on the occurrence of adverse events.
Efficacy assessments will be performed at every visit and efficacy analysis will include:
- Proportion of subjects at each study time point which will need additional IOP lowering drug therapy to achieve an IOP reduction to values < 21 mmHg. If a subject needs more than one drug to achieve target IOP, the number of drugs needed to achieve adequate IOP reduction will be recorded.
- Proportion of subjects at each time point which will need Neodymium:YAG goniopuncture to achieve an IOP reduction to values < 21 mmHg.
- Conditions
- Open Angle Glaucoma, Cataract
- Being tested
- Hyaluronan Thiomer i.o. implant

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Hyaluronan Thiomer i.o. implant in people with Open Angle Glaucoma and Cataract, run by Croma-Pharma GmbH at 1 site in Austria.
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 4 inclusion and 17 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 1 Apr 2016. 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 Austria. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Safety (time frame: Safety will be assessed up to 12 months.). 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 1 Apr 2016; AzTrials last refreshed its copy on 8 Nov 2026.
