Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A feature of the clinical trials of NEO100 is to investigate the efficacy of this drug when it is delivered intranasally. Based on the general body of data on intranasal drug delivery, as well as the promising results from clinical studies in which perillyl alcohol was delivered intranasally, NeOnc expects that intranasal administration of NEO100 will allow rapid and more selective delivery of therapeutic levels of the drug to the brain, while minimizing systemic toxicity and first pass metabolism.
The study is a dose titration 1+1 design with a modified Fibonacci dose escalation, followed by a expansion design, used to determine the maximum tolerated dose and to select a recommended Phase 2 dose (RP2D). The starting dose of 192 mg mg/dose administered QID, on a 28-day cycle, is one dose below the safe dose administered to adults in a Phase 1/2a study. Dosing will increase using a modified Fibonacci dose escalation. The daily dose will start at 768 mg/day, and rise to 1,152 mg/day, which is also the safe dose administered to adults in a Phase 1/2a study.
The study is open to patient with Pediatric-type high grade glioma: Newly diagnosed and recurrent Diffuse Midline Glioma, H3 K27-altered; Diffuse hemispheric glioma, H3 G34-mutant, grade III and IV diffuse pediatric-type HGG, H3-wildtype and IDH-wildtype (including spinal cord tumors); Recurrent malignant tumors involving the brainstem or posterior fossa (choroid plexus carcinoma, CNS embryonal tumors, and pineoblastoma).

Phase 1b safety, dose finding, brain-tumor delivery, and pharmacokinetics of IN NEO100
Patients 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.
NEO100
NEO100 is a purified form (\>98.5%) of the naturally occurring monoterpene perillyl alcohol.
NEO100 drug product is a non-sterile solution for intranasal administration. It is compounded as a 10% solution in a 50:50 mixture of ethanol:glycerol.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Karnofsky ≥ 50 for patients \> 16 years of age or Lansky ≥ 50 for patients ≤ 16 years of age. Participants who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
* If clinically indicated, participants must be willing to provide adequate tissue for PK analysis, either from a surgical biopsy or needle biopsy.
* Aged ≥5 to ≤18 years.
* Patients recurrent or progressive disease must have recovered from all acute side effects of prior therapy.
* From the projected start of scheduled study treatment, the following time periods must have elapsed: At least 7 days after last dose of a biologic agent or beyond time during which adverse events are known to occur for a biologic agent, 5 half-lives from any investigational agent, 4 weeks from cytotoxic therapy (except 23 days for temozolomide and 6 weeks from nitrosoureas), 6 weeks from antibodies, or 4 weeks (or 5 half-lives, whichever is shorter) from other anti-tumor therapies.
* Prior use of temozolomide during radiation at maximum of the standard pediatric dosing (defined as 90 mg/m2 /dose continuously during radiation therapy for 42 days) or dexamethasone is allowed.
* Corticosteroids: Patients who are receiving dexamethasone must be on a stable or decreasing dose for at least 3 days prior to baseline magnetic resonance imaging (MRI) scan.
* Surgical Resection: Patients may not have had a surgical resection within four weeks of starting NEO100 and any post-surgical complications must have resolved prior to initiation of NEO100.
* Radiation Therapy: Patients may not receive radiation therapy within four weeks of starting NEO100. Patients may not be enrolled if they require radiation therapy during Cycle 1 (the DLT Period). Patients may have SOC radiation therapy in Cycle 2 or beyond but will require a second DLT evaluation period to participate.
