The HeartSpare Plus 1B Trial

April 12, 2022 updated by: Royal Marsden NHS Foundation Trust

The HeartSpare Plus 1B Trial: A Randomised Phase II Trial Comparing the Resource Impact, Acute Toxicity and Feasibility of Different Pan-lymph Node Radiotherapy Techniques for Breast Cancer Patients

This study aims to compare the resource impact, acute toxicity and feasibility of different pan-lymph node radiotherapy techniques. Radiotherapy using wide tangents with the patient in breath hold will be compared against volumetric modulated arc therapy (VMAT) in free breathing in the main trial. A parallel study will asses the accuracy of VMAT treatments using voluntary deep inspiratory breath hold compared to an active breathing controlled breath hold device.

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

Following publication of results of two large randomised clinical trials, pan-lymph node radiotherapy (pan-LN RT) (including treatment of the internal mammary chain) is set to become standard treatment in patients with lymph-node positive breast cancer. Traditional pan-LN RT techniques deliver high radiation doses to the heart and lungs which can cause long-term side-effects in women many years after their treatment. Modern techniques including breath-holding and volumetric-modulated arc therapy (VMAT) can reduce doses to heart and lungs but the investigators do not yet know which technique(s) are best in terms of resource costs, short to medium-term side-effects, and day to day accuracy. This study will compare the time taken to deliver pan-LN RT using breath-holding versus VMAT and will collect side-effect data up to one year following treatment as well as modelling long-term cardiac risks based on heart doses delivered. The results of the main study will help guide clinicians and departments in selecting the best pan-LN RT techniques for their patients. A parallel study will evaluate the combination of breath-hold and VMAT using a machine-based technique called the active-breathing controlled (ABC) device against a more simple voluntary breath-hold technique were patients simply take a breath in and hold it for up to 20 seconds at a time. These techniques will be compared in terms of their day-to-day accuracy. If the simpler technique proves as accurate as the ABC-technique, this will establish the simpler technique as a less resource-intensive standard of care adoptable by other radiotherapy departments.

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.

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.
