Prevention of Capsular Contracture Using Trental and Vitamin E

August 27, 2013 updated by: Nathalie Johnson, Legacy Health System

A Single Center, Prospective Treatment Trial to Assess Prophylactic Use of Trental (Pentoxifylline) and Vitamin E to Prevent Capsular Contracture After Implant Reconstruction in Patients Requiring Adjuvant Radiation Therapy

The main purpose of this research study is to determine if the use of Trental and Vitamin E will decrease the incidence and severity of contractures (shrinking and or hardening of tissue surrounding the implant) associated with breast implant reconstruction following radiation treatment. Another goal is to find out the impact that Trental and Vitamin E have on implant loss or need for surgical intervention in the setting of chest wall radiation after reconstruction. In addition, the investigators want to evaluate the patient's sense of well being and quality of life.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

This is a single center, 18-month study in which 30 women will receive Trental (pentoxifylline) 400 milligrams three times a day in combination with vitamin E, 400 international units orally twice daily for six months. Subjects will begin the treatment regimen within four weeks after completion of radiation treatment and will remain on the study drugs for six months. Following completion of active treatment, all subjects will enter the twelve-month observational phase of the trial in which they will be evaluated for changes in breast tissue using the following objective tools: Bakers Grade Assessment, Visual Analog Scale (VAS), implant revision or loss, breast photographs, adverse event assessment and the Quality of Life tool (SF-12).

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.

Ages Eligible for Study

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.
Outcome Measure
Time Frame
Measure number and grade of contractures occurring after implant reconstruction and radiation treatment in subjects receiving Trental and vitamin E combination compared to placebo using the Bakers grade assessment
Time Frame: 6 months
6 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.
Outcome Measure
Time Frame
Number of implant revisions or loss of implants due to post radiation changes in subject receiving Trental and vitamin E compared to placebo through patient interview with research staff
Time Frame: 6 months
6 months
