About this study
Official title: LOC387715/HTRA1 Variants and the Response to Combined Photodynamic Therapy With Intravitreal Bevacizumab in Polypoidal Choroidal Vasculopathy
This study is to investigate whether there is an association of the LOC387715/HTRA1 variants with response to treatment with combined photodynamic therapy and intravitreal bevacizumab for patients with polypoidal choroidal vasculopathy.
Read the detailed description
This is a retrospective cohort study comprised of 70 eyes being treated for polypoidal choroidal vasculopathy with combined photodynamic therapy and intravitreal bevacizumab injections. Patients were genotyped for the LOC387715 (rs10490924) and the HTRA1 gene polymorphism (rs11200638).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| polypoidal choroidal vasculopathy | patients who were treated for polypoidal choroidal vasculopathy with combined photodynamic therapy and intravitreal bevacizumab injections |
What is being measured
The primary outcome is the main question the study is designed to answer.
Best-corrected visual acuity
Best-corrected visual acuity (BCVA) using the Snellen chart was evaluated including BCVA up to 12 months
Measured: up to 12 months
Secondary outcomes (1)
Angiographic characteristics
Fluorescein angiography (FA) and ICGA (HRA; Heidelberg Engineering, Dossenheim, Germany) was evaluated. Greatest linear dimension (GLD) was determined based on both FA and ICGA.
Measured: up to 12 months

Questions about this trial
What is this clinical trial studying?
An observational study of Age-Related Macular Degeneration, run by Kyungpook National University Hospital at 1 site in South Korea.
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 3 inclusion and 2 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 30 Aug 2011. 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 South Korea. 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?
Best-corrected visual acuity (time frame: up to 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01233115, which also lists 1 linked publication.
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 30 Aug 2011.
