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

Study therapy will consist of radiation therapy (RT) given over 17 treatment days (for 30.6 Gy in fractions of 1.8 Gy) or 20 treatment days (for 36 Gy in 1.8 Gy fractions), depending on the time from completion of the first course of RT. Treatment days will generally be weekdays, not including statutory holidays.

Study Type

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.

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.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

All of these criteria must be met for a patient to be eligible for this study:

  1. Each site may accept a patient on study of any age that they have permission to treat and follow on study per their institutional policy.
  2. The patient has no evidence of metastases on cranial or spinal MR imaging
  3. The patient has received RT in the past, given to a total cumulative dose of <60 Gy; prior radiation using opposed lateral fields, conformal 3-D fields, IMRT or using protons is acceptable
  4. At least 180 days have elapsed from the last day of primary RT for DIPG
  5. The patient has recovered from all acute and subacute toxicities of prior RT and of chemotherapy, if chemotherapy was utilized in the past
  6. The patient has been off all anti-tumour therapy for at least 14 days
  7. The patient has a Lansky score of 40% or higher
  8. The patient has a life expectancy anticipated to be at least 8 weeks with treatment using re-irradiation, with or without dexamethasone
  9. The patient has no uncontrolled medical condition (e.g., seizures, diabetes, infection) that would interfere with the delivery of rRT
  10. The patient agrees to not enroll on any other clinical trial of an anti-tumour intervention
  11. The patient agrees to report and have recorded the use of all medications taken during ReRAD therapy, from the time of diagnosis of progression or recurrence, then through and after completion of, ReRAD therapy; this includes the use of complementary, alternative and dietary therapies
  12. The patient is treated at a site where the study is approved by the local ethics board
  13. Males and females of child-bearing potential must agree to use effective birth control measures during rRT
  14. Consent, and, if applicable, assent, has been obtained according to institutional standards

Exclusion Criteria:

If the patient fulfills any of these criteria, then he or she will not be eligible for the study:

  1. Females who are pregnant, due to risks from rRT on the developing fetus.
  2. Any patient with a condition that prohibits the planned delivery of rRT as prescribed in this study.
  3. Patients who are receiving any other clinical trial of an anti-tumour intervention

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
Measure Description
Time Frame
second progression-free survival
Time Frame: up to 18 months from the start of re-irradiation
length of time from start of re-irradiation to subsequent progression of disease
up to 18 months from the start of re-irradiation

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
Measure Description
Time Frame
overall survival
Time Frame: up to three years from initial diagnosis of DIPG
time from initial diagnosis of DIPG to death following re-irradiation
up to three years from initial diagnosis of DIPG

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 15, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
