Sodium Selenite and Radiation Therapy in Treating Patients With Metastatic Cancer

May 24, 2024 updated by: Stanford University

A Phase I Study Evaluating the Efficacy and Safety of Sodium Selenite in Combination With Palliative Radiation Therapy in Patients With Metastatic Cancer

The purpose of this study is to determine the maximum-tolerated dose (MTD) of sodium selenite when administered in combination with radiation therapy to subjects with metastatic cancer based on safety and tolerability.

Study Overview

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

Primary Objectives:

  • To determine the maximum tolerated dose (MTD) of sodium selenite when given in combination with palliative radiation therapy
  • To assess the safety and tolerability of the combination of sodium selenite and palliative radiation therapy in metastatic cancer

Secondary Objectives:

  • To assess the pharmacokinetics of sodium selenite
  • To evaluate the anti tumor activity of sodium selenite and palliative radiation therapy when given in combination

OUTLINE:

Patients receive sodium selenite orally (PO) 2 hours before daily radiation therapy treatments. Treatment continues for the duration of the course of radiation therapy in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 months.

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, significant vascular disease (eg, aortic aneurysm, aortic dissection), symptomatic peripheral vascular disease, or psychiatric illness/social situations that would limit compliance with study requirements
  6. History of myocardial infarction or unstable angina within 6 months prior to study enrollment
