186Rhenium Liposome TreatmentEXPERIMENTALArm Phase I: Experimental: Dose Escalation for Cohorts 1-8 Each participant will receive a single administration of 186RNL. At each dose level, a minimum of three to a maximum of six participants will be enrolled. If no dose limiting toxicity is observed in the initial three participants, then the next higher dose level cohort will open for enrollment. The dose escalation scheme will follow a modified Fibonacci dose escalation scheme as shown below: COHORT ACTIVITY Cohort 1 (1.0 mCi) Cohort 2 (2.0 mCi) Cohort 3 (4.0 mCi) Cohort 4 (8.0 mCi) Cohort 5 (13.4 mCi) Cohort 6 (22.3 mCi) Cohort 7 (31.2 mCi) Cohort 8 (41.5 mCi) Phase 2: Single arm, prospective study utilizing a non-DLT dose obtained from the dose escalation portion of IND 116117, NIH-NCI Grant (22.3 mCi (total 186RNL activity) at a concentration of 2.5 mCi/mL and 8.8 mL total volume).
Interventions
NameTypeDescription
Rhenium Liposome TreatmentDRUGAt the time of stereotactic biopsy a catheter will be placed within the tumor using stereotactic guidance. Once the patient has adequately recovered from the procedure as determined by the neurosurgeon, 186RNL will be infused through the CED catheter at the predetermined dose. Spectroscopic imaging will then be obtained at predefined time points to visualize the distribution of the 186RNL as well as calculated the actual dose retained within the tumor. Patients will be monitored longitudinally for evidence of toxicity and response by MRI.
