Phase 1b safety, dose finding, brain-tumor delivery, and pharmacokinetics of IN NEO100EXPERIMENTALPatients will receive IN NEO100 that will follow a dose titration design, followed by a standard dose escalation design to establish safety. Brain tumor delivery of NEO100 will be confirmed in each disease sub-type by surgical resection/needle biopsy only if clinically indicated and scheduled for clinical purposes and testing with residual tissue for NEO100 and the major metabolite of NEO100 (Perillic Acid). The study will use a modified Fibonacci dose titration design, followed by a standard dose escalation design. * Cohort 1: 192 mg NEO100, QID on a 28-day cycle * Cohort 2: 288 mg NEO100, QID on a 28-day cycle * Cohort 3: 384 mg NEO100, TID on a 28-day cycle; * Cohort 4 (ceiling dose): 576 mg NEO100, BID on a 28-day cycle. Patients undergoing surgical or needle biopsy (only when clinically indicated) will receive a minimum of four days IN NEO100 treatment prior to the procedure.
