A Study of Reduced-dose Radiation in People With Metastatic Tumors With a Genetic Change

Phase 2
Recruiting
Conditions
Metastatic Cancer
Interventions
Radiation: Palliative radiotherapy
Registration Number
NCT05010031
Lead Sponsor
Memorial Sloan Kettering Cancer Center
Brief Summary

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.

Recruitment & Eligibility

Status
RECRUITING
Sex
All
Target Recruitment
29
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.
