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

Total Body Irradiation (TBI) continues to play an important role in myeloablative and non-myeloablative conditioning regimens for Allogeneic Stem Cell Transplant (ASCT). When TBI is used as part of a myeloablative regimen, it is combined with chemotherapy to eradicate malignant cells, as well as to immunosuppress the host to prevent rejection of donor hematopoietic progenitor cells (HPC).

This study is a single-institution study to assess the safety of linac based VMAT TBI for myeablative sreatment in hematologic malignancies.

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).

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.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Patients with Hematologic Malgnancies
Radiation: Linac Based VMAT TBI
Use of linac based Volumetric Arc Therapy (VMAT) to deliver Total Body Irradiation (TBI). The study intervention is a VMAT based delivery technique using a 6 MV photon beam from a Varian TrueBeam® (Palo Alto, CA) equipped with a Millennium multi-leaf collimation (MLC) system3. TBI will be delivered using a Varian TrueBeam linear accelerator with photon beam VMAT capability. VMAT is a radiation technique combining dynamic photon fluence modulation using multi-leaf collimation (MLC) with gantry rotation to deliver a highly conformal dose distribution with improved target coverage and sparing of organs at risk (OARs).

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
Proportion of Patients Who Achieve Excellent Coverage While Sparing the Lung
Time Frame: Up to 1 year post-transplant

Excellent coverage while sparing the lung is quantified by meeting the following dosimetric parameters (all parameters must be met):

  1. V100%= >90% (90% of PTV volume getting 100% of the dose).
  2. D98>85% (98% of the volume getting at least 85% of the dose).
  3. Mean Lung dose <900cGy.
Up to 1 year post-transplant

Secondary Outcome Measures
