Brief Summary:
The phase I component of the study is to identify maximal tolerated dose (MTD). The phase II is to evaluate neurocognitive decline.

Condition or disease Intervention/treatment Phase
Brain Metastases Radiation: Stereotactic Radiosurgery Phase 1 Phase 2

Detailed Description:
On review of our experience with treatment for brain metastases since 2009, we have treated over 100 patients with 6 or more metastases in a single radiosurgery session. In the past year and a half (2015-16) there have been approximately 50 patients treated with six or more metastases, indicating that there has been a shift in management of intracranial metastatic disease with increasing preference for radiosurgery despite the presences of greater metastatic burden. The phase I component will accrue 7-15 patients at each dose cohort until the MTD is determined. Once the MTD is reached, the phase II component will commence with a total of 50 patients total enrolled at the MTD, with a study time of 3 years. The primary endpoint of the phase I component is toxicity. The primary endpoint of the phase II component is the change in neurocognitive function, defined by a decline in the Hopkins Verbal Learning Test- Revised delayed recall. Data from the WBRT-alone arm of the PCI-P-120-9801 phase III trial evaluating WBRT plus motexafin gadolinium demonstrated a 30% mean relative decline in the HVLT-R delayed recall score from baseline to 4 months, with a standard deviation of 41% 9,10. More recently, in patients treated with SRS alone for 1-3 metastases versus SRS plus whole brain radiotherapy, the 4-month rates of HVLT-R delayed recall deterioration were 6% and 22% for the SRS alone arm and SRS + whole brain radiotherapy arm, respectively. Given the greater intracranial burden of disease, we estimate the mean relative decline in HVLT-R delayed recall to be intermediate between SRS alone for 1-3 metastases and whole brain radiotherapy. We predict that after SRS for multiple metastases the mean relative decline in delayed recall as 15%, an improvement over the historical control of whole brain radiotherapy alone which had a mean relative decline in HVLT-R delayed recall of 30%.

Primary Outcome Measures :
  1. Phase I: To determine the toxicity within 60 days from the date of SRS, in patients with a greater intracranial disease burden, defined as 6 or more metastases. [ Time Frame: 60 days ]

    Any subject who receives treatment on this protocol will be evaluated for toxicity. Each patient will be assessed for the development of toxicity according to the study calendar. Toxicity will be assessed according to the NCI Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0.

    The following acute (<30 days) and subacute (>30 days - <60 days) toxicities probably or definitely attributable to the protocol treatment, as defined in CTCAE v4.0, will be dose limiting toxicities (DLT) of the study.

    Grade 3 or higher neurologic toxicity in the below categories:

    • Ataxia
    • Symptomatic Central Nervous System Necrosis which is interfering with ADLs, or requiring treatment with hyperbaric oxygen, Avastin, or resection. Asymptomatic necrosis present on imaging alone does not constitute DLT.
    • Cerebral Edema (Grade 4)
    • Intracranial Hemorrhage
    • Seizure

    Any Grade 4 or 5 toxicities definitely attributable to the protocol treatment.


  2. Phase II: Determine the cognitive deterioration (HVLT delayed recall) in patients treated with SRS for multiple metastases (from baseline to 4 months) [ Time Frame: 4 months ]

    The Hopkins Verbal Learning Test (HVLT) is a memory test that gives information about memory.

    Each patient will serve as her or his own control, and the relative decline in HVLT-DR score from baseline to 4 month follow-up is defined as

    Δ HVLT-DR = (HVLT-R DR at baseline - HVLT-DR at 4 month follow up) / HVLT-DR at baseline.

    A positive change indicates a decline in function.



Secondary Outcome Measures :
  1. To determine the optimal dose which will provide local control in patients with a greater intracranial disease burden, defined as 6 or more metastases [ Time Frame: 90 days ]
    It is assumed that the optimal dose will be the maximum tolerated dose. However, the maximum tolerated dose may or may not be the most ideal dose balancing benefit and toxicity with the widest therapeutic window.

  2. To determine neurocognitive outcomes [ Time Frame: 3 years ]
    via HVLT and quality of life via FACT-Br amongst patients treated with > 6 metastases via SRS.

  3. To detemine overall survival [ Time Frame: 2 years ]
    overall survival (OS) is defined as the time between date of SRS and date of death

  4. To determine the time to distant brain recurrence [ Time Frame: 3 years ]
    distant brain recurrence is defined as time between date of SRS and development of new metastases

  5. To determine the incidence of salvage WBRT or radiosurgery [ Time Frame: 4 months ]
    WBRT is defined as whole brain radiation therapy

  6. To determine the incidence of development of leptomeningeal disease [ Time Frame: 2 years ]
    Leptomeningeal disease is an exclusion criteria for the study

  7. To prospectively collect treatment time of patients treated for multiple metastases [ Time Frame: 2 years ]
    reported in a routine manner at scheduled times during the trial
