A Study of Genetic and Environmental Factors and Their Effect on Response to Treatment With Lucentis (Ranibizumab) for Wet AMD - Full Text View

Sponsored by:	Oregon Health and Science University
Information provided by:	Oregon Health and Science University
ClinicalTrials.gov Identifier:	NCT00469352

Purpose

The purpose of this study is to understand whether genes or certain factors in the environment determine how eyes will respond to Lucentis (ranibizumab) treatment. For example, whether having variants within specific genes means that a patient is likely to get better vision from treatment than another patient with different genes.

Official Title:	The Effect of Genotype and Environmental Risk Factors on Treatment Response to Intravitreal Lucentis (Ranibizumab) for Neovascular AMD

Further study details as provided by Oregon Health and Science University:

Primary Outcome Measures:

The primary outcome measure is clinical treatment response to intravitreal Lucentis, defined as: 'Clinical stabilization' : stabilization of visual acuity. 'Clinical improvement'; 'Clinical progression' [ Time Frame: 12 months ]

Secondary Outcome Measures:

Establish the association between environmental risk factors and treatment response to intravitreal Lucentis when controlling for genotype [ Time Frame: 12 months ]
Association between central macular thickness as measured by ocular coherence tomography (OCT) in response to Lucentis treatment and genotype/environmental risk exposure. [ Time Frame: 12 months ]
Median number of intravitreal ranibizumab (Lucentis) injections required per patient [ Time Frame: 12 months ]

Estimated Enrollment:	150
Study Start Date:	May 2007
Estimated Study Completion Date:	May 2009

Detailed Description:

Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. The advanced stages of the disease are characterized by the development of geographic atrophy or choroidal neovascularization, both of which result in significant loss of vision. Development of intravitreal anti-VEGF agents such as ranibizumab has significantly improved outcomes for the neovascular for of the disease. However, it is not possible to predict which individuals will respond to the treatment.

The objective of this study is to establish the association between genetic factors and treatment response to intravitreal Lucentis. This will be accomplished by SNP-genotyping participants for AMD-susceptibility and candidate angiogenesis-pathway genes, collecting environmental risk factor variables and evaluating clinical outcomes. The aim of this pharmacogenetics study will be to identify patients at the outset of their treatment that require more intensive therapy.

Eligibility

Ages Eligible for Study:	50 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

All AMD-related CNV lesion types will be included.
Age >50 years

Exclusion Criteria:

Age <50 years;

Choroidal neovascularization not from AMD;
Concomitant non-AMD related maculopathy in study eye;
Active treatment for neovascular AMD in fellow eye;
Acuity loss or central field loss from non-AMD cause;
Pigment epithelial detachment without evidence of CNV;
Individuals in whom Lucentis is contraindicated;
Participation in another clinical trial in last three months
Pregnancy (positive pregnancy test) or lactation
Premenopausal women not using adequate contraception
Prior enrollment in the study
Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated
