About this study

Official title: High-Dose Lucentis (Ranibizumab 2.0mg) for the Treatment of Nonproliferative Idiopathic Parafoveal Telangiectasia [HD-LIPT]

Idiopathic Parafoveal Telangiectasia (IPT) [also known as Idiopathic Perifoveal Telangiectasia, Idiopathic Juxtafoveal Telangiectasia (IJT, JFT) and Macular Telangiectasia (MacTel)] is a disorder of unknown etiology. IPT is classified as Group 2A in the Gass classification of macular telangiectasias (Reference 1,5) - a bilateral, but not always symmetric disorder. It is characterized in its early stages by dilation and loss of parafoveal capillaries accompanied by angiographic leakage, "right angle" venules, central and parafoveal intraretinal cysts.

DESCRIPTION OF THE STUDY

This is an open-label, Phase I/II study of intravitreally administered ranibizumab in subjects with nonproliferative Idiopathic Parafoveal Telangiectasia (IPT).

Consented, enrolled subjects will be randomized into two groups: observation and treatment. The observation group will be monitored monthly while the treatment group will receive three open-label intravitreal injections of 1.0 mg ranibizumab administered every 30 days for 3 months and then as needed monthly, based on defined criteria. NOTE: The original protocol had the treatment group dosed at 2.0 mg/0.05mL. However, the 2.0mg dose will become unavailable beginning January 31, 2012. Therefore, the protocol amendment submitted in December 2011 changed the 2.0mg arm to a 1.0mg/ 0.10mL arm. Please note that three patients were already treated with 2.0mg before the amendment was submitted, so they will be switched to 1.0mg if they have not completed the study when the 2.0 dose is no longer available in January 2012.

Protocol: FVF4875s Final 6/P

RATIONALE FOR STUDY DESIGN

As IPT is a chronically progressive condition, the purpose of this study is to see if high-dose ranibizumab can slow or stop the leakage and growth of existing, dilated, macular vessels in cases where no co-existing neovascularization exists as defined by fluorescein angiography and Ocular Coherence Tomography (OCT). Other outcomes include stabilization of visual acuity compared to observation group (defined by best corrected Early Treatment Diabetic Retinopathy Study (ETDRS) measurements), and changes in ultrastructural features, as defined by OCT,

OUTCOME MEASURES

3.3.1 Primary Outcome Measures

To compare the change in visual acuity from baseline to one year in patients with nonproliferative IPT who are either treated with high-dose (1.0mg) ranibizumab or observed.

3.3.2 Secondary Outcome Measures

  1. To compare the change in visual acuity from baseline to 6 months and 9 months in patients with nonproliferative IPT who are either treated with high- dose (1.0mg) ranibizumab or observed. ii. To assess OCT changes in standard Central Subfield Thickness (CST) from baseline to 6 months, 9 months and 12 months. iii. To assess safety of administering 1.0mg ranibizumab (Lucentis) in patients with nonproliferative IPT at 6 months, 9 months and 12 months. iv. To assess changes in angiographic leakage from baseline at 6 and 12 months.

What is being measured

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

  1. Visual Acuity Change From Baseline to Month 12 of the Study

    Measured: Baseline to 12 months

Secondary outcomes (4)
  1. Change in Visual Acuity From Baseline to Month 6 and From Baseline to 9 Months

    Measured: Baseline to 6 months and baseline to 9 months

  2. Change in Standard Central Subfield Thickness (CST) as Measured by OCT From Baseline to 6, 9, and 12 Months

    A large decrease in CST thickness may be indicative of a worse clinical outcome. These measurements are done to ensure safety of the participants.

    Measured: Baseline to 6, 9, and 12 months

  3. Number of Adverse Events Associated to the Administration of Ranibizumab 2.0mg

    Measured: Baseline to 6 month, baseline to 9 month and baseline to 12 months

  4. Angiographic Leakage From Baseline to Month 6 and 12

    Angiography was taken via fluorescein angiography. Any increases of angiographic leakage was counted between baseline and month 6. Also any decreases of angiographic leakage was counted between baseline and 6 month. The same was done between baseline and 12 month.

    Any increase of angiographic leakage was counted as a +1. Likewise, any decrease of angiographic leakage was counted as a -1. The sum was calculated based on the number of participants in each arm and the total shown in the outcome. For example: if across the three injected participants for their 6 month visit, two of them showed an increase of angiographic leakage and one showed a decrease, then the outcome would be, (+1) + (+1) + (-1)= +1. Likewise, if the same three participant's 12 month visit showed two with a decrease in leakage and one with no changes in leakage, the outcome would be, (-1) + (-1) + (0)= -2

    Measured: Baseline to 6 and baseline to 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ranibizumab 2.0mg in people with Retinal Diseases and Telangiectasis, run by Eye Center of Northern Colorado, P.C. at 1 site in United States.

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 6 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 10 Apr 2015. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Change From Baseline to Month 12 of the Study (time frame: Baseline 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 10 Apr 2015; AzTrials last refreshed its copy on 7 Nov 2026.
