Pilot Study of Lucentis Combined With Proton Beam Irradiation in Treating Wet Age-related Macular Degeneration

Because a possible synergism of radiation and inhibitors of vascular endothelial growth factor has been shown in cancer patients and patients with wet macular degeneration, this pilot study is being conducted to determine whether treating wet macular degeneration with a combination of Lucentis and proton beam irradiation is safe. Lucentis is an inhibitor of vascular endothelial growth factor which was recently FDA approved for treatment of wet macular degeneration. It appears to be the most effective therapy thus far for wet macular degeneration among all drugs FDA approved for this condition. If no major safety issues are associated with this combination therapy, a larger study will be conducted to determine whether this combination therapy is more effective than Lucentis monotherapy.

About this study

Five subjects diagnosed with wet macular degeneration will be treated with standard of care, i.e. intravitreal Lucentis injection monthly for the first four months and as needed thereafter. Within six weeks of the first Lucentis injection, the eye will also be treated with 24 Gy of proton beam divided into two fractions. Each subject will be followed for 2 yrs with monthly examination.

Treatment and study plan

Proton beam irradiation and ranibizumab

Drug

ranibizumab 0.5mg intravitreal monthly x 4, then prn combined with low dose proton beam irradiation 24Gy (2 fractions, 24 hours apart) during the first month of study.

Other names: Lucentis and proton beam

Primary outcomes

  1. Incidence and Severity of Ocular Adverse Events

    Time frame: 24 months

    Any ocular adverse event identified by eye examination during the study follow-up will be recorded and determined for possible or probable relation to study treatment.

Secondary outcomes

  1. 1. Change in BCVA From Baseline

    Time frame: 24 months

    change in number of letter read correctly in study eye compared to the number of letters read correctly at baseline, i.e. BCVA (number of letters read correctly) at 24 months minus BCVA (number of letters read correctly) at baseline
