December 11, 2017 updated by: Masonic Cancer Center, University of Minnesota

Phase I-II Trial of Genistein in Subjects Receiving Palliative External Beam Radiation Therapy for Osseous Metastases: A Study of Palliation of Symptoms and Quality of Life

RATIONALE: Genistein may increase the effectiveness of radiation therapy in treating pain caused by bone metastases.

PURPOSE: This phase I/II trial is studying the side effects of genistein and to see how well it works in treating patients undergoing external-beam radiation therapy for pain caused by bone metastases.

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

OBJECTIVES:

  • To determine whether genistein is safe when administered in combination with palliative external beam radiotherapy in patients with osseous metastases.
  • To determine the time to pain relief, duration of pain relief, and degree of pain relief in patients treated with this regimen.
  • To determine the incidence of pathologic fractures in patients treated with this regimen.
  • To determine the effect of this regimen on quality of life measures in these patients.

OUTLINE: This is a multicenter study.

Patients undergo external beam radiotherapy once daily on days 1-10. Patients also receive oral genistein once daily on days 1-60.

Patients complete pain and quality-of-life questionnaires periodically.

After completion of study therapy, patients are followed at 30 days.

Interventional

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.

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
Safety
Time Frame: At completion of first 6 patients
Frequency of severe (grade 3) toxicities
At completion of first 6 patients

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.
