The Risk of Cancer in Users of Regranex (Becaplermin) and Matched Comparators (Nonusers of Regranex [Becaplermin])

July 15, 2016 updated by: Ethicon, Inc.

A Matched Cohort Study of Regranex (Becaplermin) and the Risk of Cancer

The purpose of this study is to compare the risk of cancers in patients who have used REGRANEX (becaplermin) to that of patients with similar characteristics and health issues who have not used REGRANEX (becaplermin). REGRANEX (becaplermin) is topical medication used to treat non-healing neuropathic foot ulcers in patients with diabetes.

Study Overview

Status

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 an observational retrospective study where data will be collected from a medical claims database derived from a large national managed care organization with over five million members. Members enrolled in a Medicare supplement program will also be included. The objective of this study is to determine the incidence of cancer among patients who have used REGRANEX (becaplermin) compared to patients who have not used REGRANEX (becaplermin). REGRANEX (becaplermin) is an FDA-approved prescription medicine that contains a platelet-derived growth factor that is used for the treatment of foot ulcers in patients with diabetes. Patients who were treated with REGRANEX (becaplermin) between January 1998 and June 2003 will be identified in a health insurance claims database. Another group of patients who have not been treated with REGRANEX (becaplermin) but have similar characteristics to patients treated with REGRANEX (becaplermin) will also be identified during the same time frame in the database. Medical record abstraction and review will be conducted to verify all incident cancers identified. Follow-up for study outcomes will be conducted from the date of accrual through termination of health-plan membership or December 2003 (whichever comes first). The date of accrual is the date of REGRANEX (becaplermin) exposure for each exposed patient and his or her matched unexposed comparison patients. Any incidence of death from cancer will also be identified. The primary outcome measure in the study will be the incidence rate of cancers of all kinds, grouped by organ site in patients who have used REGRANEX (becaplermin) and patients who have not used REGRANEX (becaplermin). A secondary objective is a similar comparison of the incidence of death from cancer. This is an observational study; no investigational drug will be administered.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

20 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Probability Sample

Study Population

Patients with similar characteristics who were treated or who were not treated with REGRANEX (becaplermin) between January 1998 and June 2003 identified in a health insurance claims database.

Description

Inclusion Criteria:

  • Must have at least 6 months of continuous enrollment in health plan prior to Regranex initiation

Exclusion Criteria:

  • Any cancer-related diagnoses identified in the claims data during baseline (the 6 month period prior to REGRANEX (becaplermin) initiation).

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
The number of reported cases of cancers of all kinds, grouped by organ site in patients who have used REGRANEX (becaplermin) and patients who have not used not used REGRANEX (becaplermin).
Time Frame: From the date of accrual until the earliest of December 2003, outcome identification, health plan disenrollment, or death
From the date of accrual until the earliest of December 2003, outcome identification, health plan disenrollment, or death

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
The number of reported deaths from cancer in patients who have used REGRANEX (becaplermin) and patients who have not used not used REGRANEX (becaplermin).
Time Frame: From the date of accrual until the earliest of December 2003, outcome identification, health plan disenrollment, or death
From the date of accrual until the earliest of December 2003, outcome identification, health plan disenrollment, or death
