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

June 28, 2016 updated by: University of California, Davis

Phase 1 Pilot Open Label Prospective Observational Study of Safety and Tolerability of Lucentis Combined With Proton Beam Irradiation in Treating Exudative 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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Measure Description
Time Frame
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.
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
