NCT03520504

Brief Summary

The purpose of this study is to find the safest and most effective dose for delivering proton beam to the space containing CSF, brain, and spinal cord, in treating leptomeningeal metastases. The researchers think that using proton beam radiation to treat the space containing CSF, brain, and spinal cord, instead of treating only the areas where the metastasized tumor cells are causing symptoms, would improve the treatment of this disease.

Outcome Measures

Primary Outcomes (1)

  • number of patients with dose-limiting toxicity

    will be assessed by physician-graded CTCEAv4

    2 years

Study Arms (1)

Proton Radiation

EXPERIMENTAL

Patients will be enrolled to receive 30Gy (RBE) in 3Gy (RBE) or 25Gy (RBE) in 2.5Gy (RBE) fractions course of proton CSI. The first 3 patients will be enrolled at dose level 30Gy (RBE) in 3Gy(RBE) fractions. If 1 or fewer patients develop dose-limiting toxicity (DLT), 3 additional patients will be enrolled. If 1 or fewer of the 6 patients experiences a DLT, the trial will proceed to the dose expansion cohort at 30Gy (RBE) . In contrast, if 2 or more patients experience a treatment DLT, 3 patients will be enrolled at dose level 25Gy (RBE) in 2.5Gy(RBE) fractions. If 1 or fewer patients develop a DLT, an additional three patients will be enrolled. If 2 or more patients experience a DLT at 25Gy, the study will be stopped. If 1 or fewer patients develop a DLT in these 6 patients, the trial will proceed to the dose expansion cohort at 25Gy (RBE) and the 6 patients who were treated in Phase Ib will be included in full assessment of safety and efficacy.

Radiation: Proton craniospinal irradiation (CSI)

Interventions

Patients will be enrolled to receive 30Gy (RBE) in 3Gy (RBE) or 25Gy (RBE) in 2.5Gy (RBE) fractions course of proton CSI.

  • Patient with extensive systemic disease and without reasonable systemic treatment options.
  • Patient who is unable to undergo MRI brain and spine with gadolinium contrast.
  • Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances.
  • Pregnant or lactating women.
