Wet Macular Degeneration Study to Compare Ranibizumab or Bevacizumab to Aflibercept

23 de julio de 2018 actualizado por: Rishi Singh

A Single Arm, Investigator Initiated Study of the Efficacy, Safety, and Tolerability of Intravitreal Aflibercept Injection in Subjects With Exudative Age-related Macular Degeneration Previously Treated With Ranibizumab or Bevacizumab (ASSESS Study)

This study will examine the use of Aflibercept in patients with exudative macular degeneration requiring intravitreal injections. Patients will be followed for 24 months. The follow up phase will be completed at month 36.

Descripción detallada

The purpose of this study is to examine the use of Aflibercept in patients who have been previously treated with Ranibizumab or Bevacizumab for exudative macular degeneration. Specifically, we will examine its effect on macular degeneration, measured by SDOCT (Spectral Domain Optical Coherence Tomography) and ETDRS (Early Treatment Diabetic Retinopathy Study) visual acuity. This will be a prospective study with patients to receive an intravitreal injection of Aflibercept at the time of treatment.

Inclusion Criteria

A subject must meet the following criteria to be eligible for inclusion in the study:

  1. Signed Informed Consent.
  2. Men and women ≥ 50 years of age.
  3. Active primary subfoveal choroidal neovascularization (CNV) lesions secondary to AMD, including juxtafoveal lesions that affect the fovea as evidenced by historical optical coherence tomographies (OCTs) and angiograms in the study eye.
  4. CNV must be at least 50% of total lesion size by either previous or current angiogram.
  5. ETDRS best-corrected visual acuity of: 20/25 to 20/320 (letter score of 73 to 25) in the study eye.
  6. Willing, committed, and able to return for all clinic visits and complete all study related procedures.
  7. At least one injection of Ranibizumab or Bevacizumab within 3 months of enrollment for active exudative AMD.
  8. Active need for anti- vascular endothelial growth factor (anti-VEGF) therapy at study entry based on the following criteria:

    1. Presence of fluid by either optical coherence tomography (OCT) or clinical examination (further defined as intraretinal, cystoid, subretinal, worsening pigment epithelial detachment)
    2. Presence of new hemorrhage on clinical examination

Exclusion Criteria

A subject who meets any of the following criteria will be excluded from the study:

  1. Any prior or concomitant therapy with another investigational agent to treat neovascular AMD in the study eye, except dietary supplements or vitamins.
  2. Prior systemic anti-VEGF therapy, investigational or FDA/Health Canada approved, is only allowed up to 3 months prior to first dose, and will not be allowed during the study.
  3. Presence of retinal pigment epithelial tears or rips involving the macula in the study
  4. History of any vitreous hemorrhage within 4 weeks prior to Visit 1 in the study eye.
  5. Presence of other causes of CNV, including pathologic myopia (spherical equivalent of -8 diopters or more negative, or axial length of 25 mm or more), ocular histoplasmosis syndrome, angioid streaks, choroidal rupture, or multifocal choroiditis in the study eye.
  6. History or clinical evidence of diabetic retinopathy, diabetic macular edema or any other vascular disease affecting the retina, other than AMD, in either eye.
  7. Prior vitrectomy in the study eye.
  8. History of retinal detachment or treatment or surgery for retinal detachment in the study eye.
  9. Any history of macular hole of stage 2 and above in the study eye.
  10. Any intraocular or periocular surgery within 3 months of Day 1 on the study eye, except lid surgery, which may not have taken place within 1 month of day 1, as long as it's unlikely to interfere with the injection.
  11. Prior trabeculectomy or other filtration surgery in the study eye.
  12. Uncontrolled glaucoma at baseline evaluation (defined as intraocular pressure ≥25 mmHg despite treatment with anti-glaucoma medication) in the study eye.
  13. Active intraocular inflammation in either eye.
  14. Active ocular or periocular infection in either eye.
  15. Any ocular or periocular infection within the last 2 weeks prior to Screening in either eye.
  16. Any history of uveitis in either eye.
  17. Active scleritis or episcleritis in either eye.
  18. Presence or history of scleromalacia in either eye.
  19. Aphakia or pseudophakia with absence of posterior capsule (unless it occurred as a result of a yttrium aluminum garnet (YAG) posterior capsulotomy) in the study eye.
  20. Previous therapeutic radiation in the region of the study eye.
  21. History of corneal transplant or corneal dystrophy in the study eye.
  22. Significant media opacities, including cataract, in the study eye which might interfere with visual acuity, assessment of safety, or fundus photography.
  23. Any concurrent intraocular condition in the study eye (e.g. cataract) that, in the opinion of the investigator, could require either medical or surgical intervention during the 52 week study period.
  24. Any concurrent ocular condition in the study eye which, in the opinion of the investigator, could either increase the risk to the subject beyond what is to be expected from standard procedures of intraocular injection, or which otherwise may interfere with the injection procedure or with evaluation of efficacy or safety.
  25. Participation as a subject in any clinical study within the 12 weeks prior to Day 1.
  26. Any systemic with an investigational agent in the past 3 months prior to Day 1.
  27. The use of long acting intraocular steroids or photodynamic therapy in the 6 months prior to day 1.
  28. Any history of allergy to povidone iodine.
  29. Pregnant or breast-feeding women
  30. Women of childbearing potential* who are unwilling to practice adequate contraception during the study (adequate contraceptive measures include stable use of oral contraceptives or other prescription pharmaceutical contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device (IUD); bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly)

    • *Postmenopausal women must be amenorrheic for at least 12 months in order not to be considered of child bearing potential. Pregnancy testing and contraception are not required for women with documented hysterectomy or tubal ligation.

Periodo de tiempo: Baseline and 12 months
The mean absolute change from baseline in best-corrected visual acuity score at 12 months as measured by Eletronic-Early Treatment in Diabetic Retinopathy Scale (E-ETDRS) protocol. There were no sub scales used. These are common methods for ophthalmology studies to report their findings. The scale provided is the Electronic-Early Treatment in Diabetic Retinopathy Scale (E-ETDRS) best corrected visual acuity scale. Values that are higher are considered better and values that are lower are considered worse. Minimum E-ETDRS was 24 E-ETDRS letters and maximum E-ETDRS was 80 E-ETDRS letters.
