We present a mechanistic mathematical model describing key interactions of a personalized neoantigen cancer vaccine with an individual patient’s immune system. Despite the notable progress, significant challenges remain in obtaining consistent immune responses across heterogeneous patient populations, as well as various cancers. Multiple successful clinical applications of cancer vaccines have shown good safety and efficacy.

The libary enables bi-directional communications to a PCAN-Ethernet Gateway DR hardware unit sold by Peak-Systems.Peak-System CAN- und LIN-Schnittstellen, Feldbus-Kommunikation. CAN-Ethernet Gateway is a C library that allows for easy communication with a CAN Bus over IP networks. This model, although complex, can be used to describe, simulate, and predict the behavior of the human immune system to a personalized cancer vaccine.J1939/CAN Ethernet Gateway. Model simulations predicted both immune responses, represented by T cell counts, to the vaccine as well as clinical outcome (determined as change of tumor size). We parametrized the model using patient-specific data from a clinical study in which individualized cancer vaccines were used to treat six melanoma patients.

This type of individualized immunotherapy has the potential to be specific, efficacious, and safe since it induces an immune response to protein targets not found on normal cells. Personalized cancer vaccines have gained attention in recent years due to the advances in sequencing techniques that have facilitated the identification of multiple tumor-specific mutations.

The cellular level describes the differentiation of dendritic cells due to peptides and adjuvant concentrations in the vaccine, activation, and proliferation of T cells in response to treatment, and tumor growth. The molecular level captures the processing and presentation of neoantigens by dendritic cells to the T cells using cell surface proteins. This model describes the interactions of a personalized neoantigen peptide cancer vaccine, the human immune system and tumor cells operating at the molecular and cellular level.

These mutations are highly patient- and tumor-specific. Tumor-specific antigens (TSAs), or neoantigens, carry the amino acid substitutions derived from random somatic mutations that are expressed only on tumor cell surface. However, tumor gene expression and mutations are immensely diverse, and how they affect outcomes for individual patients remains poorly understood. Therapeutic strategies that incorporate personalized cancer vaccines have gained attention due to successes in targeting multiple tumor-specific mutations. The goal is exploiting the patient’s immune system to target antigens expressed only on tumor cells, in order to selectively eliminate cancer cells.

Despite some successes with the strategy of designing personalized neoantigen cancer vaccines described above, significant challenges remain. Eliciting immune responses to protein targets not found on normal cells reduces the probability of immune toxicities. Individualized immunotherapies designed based on these principles have the potential to be specific, efficacious, and safe. From the large number of neo-sequences identified, the selection of the few neo-sequences to be used as neoantigens in cancer vaccines largely is based on the affinity of the neoantigens peptides to the patient’s major histocompatibility complex-I (MHC-I) and MHC-II proteins. These neo-sequences carry somatic mutations exhibiting sequences that are different from the wild type, and hence can be recognized as nonself by the host immune system, with a high probability of eliciting a cancer-specific immune response. Subsequent workflows using bioinformatic tools allow the identification of neo-sequences.

Although these studies provide insights into the interactions between treatments and immune response by modeling cell- and/or tissue-level immune dynamics, components of immune dynamics at the molecular level are lacking. To date, several mathematical models have been developed to predict the effect of mono or combination immunotherapies against cancer. Models can facilitate the development of testable hypotheses by providing quantitative estimates for numerous outcomes produced by dynamic interactions between various biological mechanisms. A mathematical model simplifies complex biological systems, provides insights into known mechanisms of the systems, and can aid researchers and clinicians better understand the disease and treatment. Mathematical modeling in biology and medicine, especially oncology , can be a powerful tool for the generation of experimental and clinical hypotheses to aid in study design. The models also can guide such decisions on treatment regimens such as dosing and infusion frequencies.

On the other hand, Patient 2 and 6, initially diagnosed with Stage 4 melanoma, showed disease recurrence after the vaccine treatment. The clinical trial , briefly reported that four patients (1, 3, 4, and 5), initially diagnosed with Stage 3 melanoma, exhibited no recurrence of the disease following the treatment regimen with the cancer vaccine. The model presented here addresses this critical unmet need.Longitudinal model forecasts of change of tumor size in clinical trial patientsTo further explore the utility of our model, we used the best-fit parameter values in Table 1 to predict the change of tumor size of individual patients. Thus, a model that successfully describes the immune response elicited by a cancer vaccine (and the subsequent effect on tumors) will need to include the molecular parameters and events that drive the immunological cascade. Key molecular events that may impact the immune response and clinical outcome include, antigen processing and presentation, and MHC-T cell binding.

We computationally estimated the tumor size (diameter in millimeters cell counts highlighted in yellow) 200 days after treatment initiation for all six patients (see Fig 2).
