Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase I Treatment Active 21 and over Other 4192s NCT00456495

Trial Description

Summary

The purpose of this study is to test the safety and tolerability of subconjunctival injection of ranibizumab in the treatment of malignant conjunctival neoplasia using the incidence and severity of adverse events.

Our secondary objective is to assess the efficacy of ranibizumab treatment on malignant conjunctival neoplasia by evaluating tumor destruction or reduction as documented by slit-lamp photography and ultrasonographic imaging and the regression of blood vessels.

Further Study Information

Ranibizumab is a recently approved vascular endothelial growth factor (VEGF) inhibitor shown to be effective in treating exudative macular degeneration. Its analog, Avastin has also been employed to treat macular edema, proliferative diabetic retinopathy and wet age related macular degeneration. Ranibizumab binds to and inhibits vascular endothelial growth factor A (VEGF-A), which has been shown to cause neovascularization and leakage in models of ocular angiogenesis. Binding to VEGF-A prevents ranibizumab's interaction with VEGFR-1 and -2 receptors on the surface of endothelial cells, thereby reducing proliferation, vascular leakage, and angiogenesis.

Given that conjunctival tumors require the formation of new blood vessels to supply the proliferating cells, we propose a study to evaluate the effect of subconjunctival ranibizumab as a primary intervention in patients with conjunctival tumors.

Eligibility Criteria

Inclusion Criteria:

• Ability to provide written informed consent and comply with study assessments for the full duration of the study

The following are considered effective means of contraception: surgical sterilization or use of oral contraceptives, barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel, an IUD, or contraceptive hormone implant or patch.

• Current infection or inflammation in either eye

• Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated

• Participation in another simultaneous medical investigation or trial
