About this trial

The primary objective will be to demonstrate the manufacturing feasibility and safety, and to determine the maximum tolerated dose (MTD) of RNA-LP vaccines in (Stratum 1) adult patients with newly diagnosed GBM (MGMT low level or unmethylated in adults only) and (Stratum 2) in pediatric patients with newly diagnosed HGG (pHGG). Funding Source - FDA OOPD

Eligibility criteria

Qualifiers

Age ≥ 21 years.

Histopathologically proven newly-diagnosed de novo GBM (WHO Grade IV glioma, secondary GBM not eligible) that is MGMT low level or unmethylated.

The tumor must have a supratentorial component.

Patient must have been enrolled on a screening consent and have had sterile collection of tumor material in a manner suitable for RNA extraction, amplification, and loading of lipid particles (LPs).

Disqualifiers

Prior invasive malignancy (except for non-melanomatous skin cancer) unless disease free for ≥ 3 years. (For example, carcinoma in situ of the breast, oral cavity, and cervix are all permissible.)

MGMT Methylated tumors

Gliomatosis Cerebri

Metastases detected below the tentorium or beyond the cranial vault and leptomeningeal involvement.

Trial design

Treatments tested in this trial
