About this study

Official title: A Pilot Study With Reduced Fluence Photodynamic Therapy With Visudyne Ranibizumab VS. Ranibizumab Only to Treat Exudative AMD

The purposes of this study is to determine if combination reduced fluence photodynamic therapy and Ranibizumab has:

Similar efficacy to Ranibizumab (Lucentis) alone. The ability to reduce the number of intravitreal injection of Ranibizumab or a 13 month period The ability to reduce the number of PDT treatments. The study will also collect information on the safety of combination therapy and single therapy.

Read the detailed description

This will be a 13 month prospective, blinded, randomized sham controled parallel safety study. There will be 2 treatment arms.

Arm 1 will receive reduced fluence PDT at baseline followed immediately by an intravitreal injection of Lucentis. Subjects in arm 1 will receive 2 additional injections of Ranibizumab (Lucentis) over the next 2 months. Starting at month 3, they will receive combination reduced fluence PDT and intravitreal Ranibizumab (Lucentis) if they develop recurrence of the subretinal fluid, cystoid macular edema, increased pigment epithelial detachment (PED), or increased retinal thickness > 100 microns compared to the best prior thickness measure on OCT. Patients will be eligible for repeat combination reduced fluence PDT + intravitreal Ranibizumab (Lucentis) every 3 months thereafter. Group 1 patients are eligible for treatment with combination reduced fluence PDT and Ranibizumab (Lucentis) at any point at the 3 month time point or thereafter. After month 3, if patients were not eligible for combined therapy (<3 months since the last combination therapy) and have >2 lines of vision loss or > 100 microns of increased retinal thickness on OCT compared to most recent measure at their monthly visit, they would be eligible for an injection of Ranibizumab (Lucentis) as monotherapy. Thereafter, subjects will have combination therapy if retreatment criteria were met and it has been >3 months since the last PDT treatment.

Study arm 2 will receive 3 monthly intravitreal injections of Ranibizumab (Lucentis). Following month 2, they will be eligible for re-treatment with Ranibizumab (Lucentis) if retreatment criteria are met (same criteria as study arm 1). At intervals of no less than 3 months from the previous sham PDT, they will receive sham PDT if retreatment criteria are met.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RanibizumabDrug

    Also called Lucentis

    Ranibizumab, and reduced fluence PDT or sham PDT and Ranibizumab. For 2 months injected intravitreal Ranibizumab will be given. At month 3 subjects will receive combination reduced fluence PDT and intravitreal Ranibizumab. If they develop recurrence of subretinal fluid, cystoid macular edema, increased pigment epithelial detachment (PED), or increased retinal thickness >100 microns compared to best thickness measure of OCT, subjects will be eligible for repeat combination reduced fluence PDT + intravitreal Ranibizumab every 3 months thereafter.

  • Ranibizumab monotherapyDrug

    Also called lucentis

    3 monthly intravitreal injections of Ranibizumab monotherapy. After month 2 they are eligible for retreatment with Ranibizumab if retreatment criteria are met (same as arm 1) At intervals of no less than 3 months from the previous sham PDT they will receive sham PDT if retreatment criteria are met.

What is being measured

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

  1. Primary efficacy will be proportion of subjects with best corrected visual acuity improvement of 15 or more letters from baseline and wil visual acuity stabilization, less than 15 letter loss from baseline at 13 months

    Measured: at conclusion of subject enrollment

Secondary outcomes (1)
  1. Mean change in ETDRS from baseline, number of Ranibizumab treatments w/reduced fluence PDT, proportion of patients with 6 lines of vision loss

    Measured: at conclusion of subject enrollment

Questions about this trial

What is this clinical trial studying?

A study testing Ranibizumab and Ranibizumab monotherapy in people with Macular Edema, run by Lahey Clinic.

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 7 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: withdrawn, as of the sponsor's last update on 10 May 2012. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

Primary efficacy will be proportion of subjects with best corrected visual acuity improvement of 15 or more letters from baseline and wil visual acuity stabilization, less than 15 letter loss from baseline at 13 months (time frame: at conclusion of subject enrollment). 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 May 2012.
