SUMMARY

Gliomas are a heterogeneous group of tumors arising from glial cells in the central nervous system and are associated with poor prognosis and significant morbidity. The most aggressive form, glioblastoma multiforme (GBM), remains particularly challenging to treat, often exhibiting resistance to conventional therapies such as chemotherapy and radiation. The average survival for patients with GBM is approximately 15 months, underscoring the urgent need for novel therapeutic strategies that can improve outcomes. Malignant gliomas are the most common primary brain cancer diagnosed and still carry a poor prognosis despite aggressive multimodal management. Despite the continued advances in immunotherapy for other cancer types, however, there remain no FDA approved immunotherapies for cancers such as glioblastoma. Neoantigen vaccines are a form of immunotherapy involving the use of DNA, mRNA, and proteins derived from non-synonymous mutations identified in patient tumor tissue samples to stimulate tumor-specific T-cell reactivity leading to enhance tumor targeting. Up to and including the current time, we have only nascent understandings, at the molecular and submolecular level, of how immunity is generated and maintained. As a result, we do not have fundamental mechanistic understandings of vaccine:antigen interactions, of vaccine-directed and initiated routes of immunity, nor how, through adjuvants and changes in our biologic environment (such as the intestinal microbiome), we might direct such immune responses. In particular, in the field of vaccinology we have few collaborations between biology, physics, and chemistry...or what has been termed convergence science...but particularly from physics and the field of quantum mechanics. Biophysics led to quantum biology and quantum immunology reflecting quantum dynamics within living systems and their evolution. Unfortunately, despite the seismic influence of immunotherapy on oncology today, there remain no FDA approved immunotherapies for GBM due to the lack of efficacy observed in several randomized clinical trials. The TAMAVAQ approaches enable a quantitative understanding of immune response kinetics following neoantigen-based peptide vaccine treatment. Insights gained from challenges can be used to design better vaccines and evaluate the potential candidate vaccines in silico. The TAMAVAQ models also can guide such decisions on treatment regimens such as dosing and infusion frequencies.

⁃ These inclusion criteria are designed to ensure that the study population for this glioma targeted personalized neoantigen vaccine clinical trial is suitable for participation, allowing for the collection of meaningful data regarding the safety and efficacy of the investigational treatment. By clearly defining eligibility, the trial aims to target patients who are most likely to benefit from this AI-QMMM inspired therapeutic approach.

Treatments
Experimental: Experimental: personalized vaccine patients with recurrent malignant gliomas enrolled into this arm
Clinical event timeline and Dosing of TAMAVAQ VACCINES~Clinical event timeline for the patients who received at least one vaccine dose of (20-200)μg TAMAVAQ NeoVaccine, will be calculated from surgery until time of death due to progressive disease. Median progression-free survival (PFS) and overall survival (OS) will be also calculated respectively. Among enrolled patients, a median of (110-145) somatic single-nucleotide variants per tumour (range, 75-158) will be tested with a median of (58-63) coding mutations per tumour (range, 32-93) using whole-exome sequencing, and the expression of a subset of genes will be confirmed by RNA sequencing (RNA-seq) analysis. These included mutations commonly observed in glioblastoma that affect PTEN, RB1 and EGFR. No IDH1 or IDH2 mutations will be also tested. A median of 60.5-70,8 HLA binders (range, 30-163) with a half-maximum inhibitory concentration (IC50) \< 500 nM will be predicted per tumour.
