The Effect of Bevacizumab (Avastin) on Pterygium

May 20, 2014 updated by: University of Alabama at Birmingham
The purpose of this study is to determine whether local injection of bevacizumab might halt and or cause regression of pterygium growth. This may enable earlier treatment and prevention of pterygium growth into the patient's line of sight thereby limiting the need for surgery and improving quality of life for patients with pterygia.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Bevacizumab
Bevacizumab injection: 0.1ml, 6 monthly doses plus baseline and 1 week post baseline
Upon enrollment into the study: - initial injection of bevacizumab, a 1 week post-injection visit,and monthly visits thereafter for a total of 6 months. At the 1-month and 3-month visit post-injection visit, an additional bevacizumab injection will be offered if pterygium regression has not occurred. All injections of bevacizumab will consist of injecting 0.1mL of a 2.5mg/0.1mL concentration of bevacizumab into the head of the pterygium.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Area the Pterygium Enlarged or Regressed as Measured From the Limbus Before and After Subconjunctival Bevacizumab Injection.
Time Frame: Baseline and 3 months

Growth of the pterygium was defined as an increase in the area of the pterygium as measured from the limbus toward the visual axis. This would be a positive change value indicating progression

Regression of the pterygium was defined as a decrease in the area of the pterygium length measured from the limbus toward the visual axis. This would be negative change value indicating regression.

Baseline and 3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Patients Having Surgical Removal of Pterygium.
Time Frame: 12 months
The number of patients having surgical removal of pterygium within 12 months.
12 months
