Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will test whether reduced-dose radiotherapy is an effective treatment for metastatic tumors with an ATM mutation. The researchers want to find the lowest dose of radiation that would still be effective to treat these tumors.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

radiation

Subjects will receive reduced dose radiation to radiographically progressive lesions identified on imaging (including asymptomatic bone metastases).

Group Type EXPERIMENTAL

Palliative radiotherapy

Intervention Type RADIATION

An initial cohort of 12 evaluable patients will be treated with 4Gyx2, with adaptive dosing planned for expansion cohorts pending the number of failures observed after 6 month observation of the initial cohort.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Histologically confirmed malignancy with at least one metastatic lesion referred for palliative radiotherapy
* Pathogenic mutation in ATM (somatic and germline allowed)
* ECOG performance status 0-2
* Age ≥ 18 years.
* Able to provide informed consent.
* Patients at reproductive potential must agree to practice an effective contraceptive method during radiation treatments.
* Expected life expectancy of at least 6 months

Exclusion Criteria

* Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances.
* Serious medical co-morbidities precluding radiotherapy.
* Pregnant or breast-feeding women.
* Lesions excluded from de-escalation include regions in which the risk of local disease progression is unacceptably high, including CNS disease and cord compression, and areas in which re-irradiation would not be feasible, including spinal cord overlap.
