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

45 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

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.

The Intrabeam Photon Radiosurgery System will deliver 20 Gy in the act of breast surgery
Procedure: Breast conservative surgery
Breast conservative surgery with the aim of resecting breast tumour and with or without oncoplastic surgery
Radiation: External Beam Hypofractionated Radiotherapy (EBRT)

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
Changes in Cosmetic results - BCCT
Time Frame: Baseline and every 12 months until 60 months
It will be measured by the BCCT.core software programme. This software uses 4 photographies of the breast for each timepoint and evaluates cosmetic outcome based upon symmetry, skin colour changes and surgical scar appearance. The lower the calculated score, the better the cosmetic outcome (1=excellent, 2=good, 3=fair, 4=poor)
Baseline and every 12 months until 60 months
Changes in Cosmetic results - Self Evaluation using YBT
Time Frame: Baseline and every 12 months until 60 months
Questionnaire for cosmetic self-evaluation from the Young Boost Trial (YBT) that consists s of 8 questions about various aspects (size, shape, skin colour, massiveness of the breast, nipple position, general appearance, visibility of the surgical scar, and overall satisfaction) to evaluate the degree of satisfaction of the patients themselves about the cosmetic results.
Baseline and every 12 months until 60 months

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
Changes in Quality of life (QOL) - General
Time Frame: Baseline and every 12 months until 60 months
It will be measured by the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaires QLQ-C30
Baseline and every 12 months until 60 months
Toxicity (acute and late)
Time Frame: Baseline and every 12 months until 60 months
Defined according to the NCI criteria published in the Common Terminology Criteria for Adverse Events (CTCAE) v4.0
Baseline and every 12 months until 60 months
Local control
Time Frame: Baseline and every 3 months after completion of EBRT and thereafter every 6 months for 5 years
Defined as histologically-confirmed evidence of tumour recurrence in the ipsilateral breast
Baseline and every 3 months after completion of EBRT and thereafter every 6 months for 5 years
Changes in Quality of life (QOL) - Breast
Time Frame: Baseline and every 12 months until 60 months
It will be measured by the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaires QLQ-BR23
Baseline and every 12 months until 60 months

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.

Primary Completion (ANTICIPATED)

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.
