April 27, 2022 updated by: Mette Felter, Herlev Hospital

SOFT - A Phase 2 Study of Stereotactic Ablative Radiotherapy of Infra-diaphragmatic Soft Tissue Metastases

The SOFT study will evaluate the feasibility and safety of MR-guided stereotactic ablative radiotherapy (SABR) for infra-diaphragmatic soft tissue metastases.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

The investigators wish to evaluate the safety and feasibility of MR-guided stereotactic radiation to patients with infra-diaphragmatic oligometastatic disease including quality of life assessments and patient-reported outcome measures. Further, the investigators assess clinical response among patients with oligometastatic disease (OMD), defined as up to five metastases in up to three different organs.

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.

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

18 years to 99 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Histology or cytology proven non-haematological cancer.
  • At least one metastasis should be localized in the infra-diaphragmatic soft tissue.
  • Eastern Cooperative Oncology Group (ECOG) scale of performance status ≤ 2.
  • ≥ 18 years old.
  • Life expectancy > 6 months.
  • Target diameter (GTV) ≤ 5 cm.
  • Metastatic lesions must be visible, imaging defined targets and suitable for treatment with SABR.
  • In case of de novo OMD and oligometastatic recurrence a maximum of 5 targets (including the primary tumour) in a maximum of 3 organ sites are allowed.
  • In case of oligoprogressive disease (OPD) * and induced OMD ** only 3 metastases (including the primary tumour) are allowed.
  • All metastatic sites are treated or planned for ablative therapy (including surgery). For OPD, only the sites in progression is required to fulfil this criterion.
  • A baseline scan within 28 days of inclusion (PET-CT or CT and MR scanning).
  • No curative intended treatment option available.
  • An ablative strategy should be deemed clinically relevant and it is at the discretion of the treating physician to decide.
  • Ability to understand and the willingness to sign a written informed consent document.
  • If the target is in the liver, a Child-Pugh Score A is required.

Exclusion Criteria:

  • Patient cannot tolerate physical set up required for SABR.
  • Active bowel obstruction.
  • Uncontrolled intercurrent illness.
  • Medical contraindication to undergoing MR-imaging.
  • Pregnancy.
  • Patients with uncontrolled brain metastases.
  • Uncontrolled disease in respect to malignant pleural effusion, ascites, lymphangitic carcinomatosis, pleural carcinomatosis or peritoneal carcinomatosis.
  • If the patient has received previous radiotherapy, the combined dose at the radiation site must not exceed the dose constraints.

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.
EXPERIMENTAL: Radiotherapy
Patients with oligometastatic lesions, fulfilling the inclusion/exclusion criteria's will be assigned to SABR.

Three different dose fractionation schemes will be available: 45 Gy in 3 fractions, 50 Gy in 5 fractions, and 60 Gy in 8 fractions.

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
Cumulative CTCAE grade ≥ 4 SABR related toxicity (TRAE).
Time Frame: Assessed at 1 year.
Registration of toxicity will be assessed according to a prespecified selection of organ related adverse events defined by CTCAE version 5.0.
Assessed at 1 year.

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
Freedom from local progression.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
Defined as the time from inclusion to local progression as determined by investigator using RECIST 1.1 criteria.
Assessed at week 6, 12, 24, 36, and 52.
Progression free survival.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
The time from inclusion until disease progression determined by investigator assessment of objective disease assessment per RECIST 1.1 .

Time to progression (TTP) outside the radiation field.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
Defined as the time from inclusion until progression outside the radiation field determined by a CT, MR, or PET-CT per RECIST 1.1. Outside the radiation field is defined as outside and not adjacent to the PTV.
