About this trial

Randomized, post-market multi-center study investigating the efficacy of two sets of treatment algorithms in brain metastases (BM) patients at the time of first intervention for radiographic progression after stereotactic radiosurgery (SRS), with or without surgery.

Eligibility criteria

Qualifiers

Patients with radiographically proven (by gadolinium-enhanced [Gd-] MRI) parenchymal brain metastases from histologically confirmed non-central nervous system (CNS) cancer.

Patients with a "targetable", bidimensionally-measurable, intracranial lesion that is radiographically recurrent after previous treatment with SRS +/- surgery (craniotomy or LITT). To classify a lesion as radiographically progressive, the lesion must demonstrate a ≥ 25% increase in size following treatment based on the Neuro-Oncology Criteria of Tumor Response for CNS Tumors. To be "targetable" for this study, the lesion should be coverable through a planned single LITT trajectory and thus have a maximum perpendicular diameter (perpendicular to the laser trajectory) of 3 cm. An intra-operative decision to utilize two trajectories is acceptable and patient may remain on study.

Patient must be at least 3 months post initial SRS treatment of the target lesion

Target lesion must be amenable to undergo surgical biopsy and LITT treatment as determined by the treating neurosurgeon.

Disqualifiers

Patients with greater than 3 progressing lesions at time of enrollment. To classify as a radiographically progressive, lesion must demonstrate a ≥ 25% increase in size following treatment based on the RANO criteria. Of note, there is no exclusion for total number of metastases. However, only one lesion can be selected to be the targeted lesion and this lesion alone may be ablated during the study procedure.

Patients with concomitant newly diagnosed intracranial metastases (concurrent with the targetable radiographically progressive lesion), as these will require prioritized and different treatment approaches.

Prior bevacizumab use within 4 weeks of study initiation

Patients with additional concurrent malignancies requiring active treatment, except non-melanoma skin cancer, or in-situ cancer of the cervix
