Our technology
Our pharmaceutical product, pTTL (Personalised Tumour Trained Lymphocytes), offers a unique personalised cell therapy designed to target and eliminate cancer with comparably mild side effects. Currently, pTTL is being evaluated in a Phase I/II clinical trial.
Our tools include two proprietary technologies: PIOR® and EpiTCer®. These tools excel in identifying the most effective neoantigens to activate and amplify T lymphocytes (also known as T cells) to eradicate the cancer.
pTTL: Personalised cancer therapy explained
The patient’s tumour is compared to healthy tissue from the patient, using DNA and RNA sequencing (1). Then the PIOR® system is used to identify optimal neoantigens to target and personalised EpiTCer® beads are manufactured (2). The patient’s own antigen-presenting cells (APCs) and T cells are derived from the tumour-draining lymph nodes and are mixed with the EpiTCer® beads, leading to expansion of tumour-targeting T cells (3). After a 2-week expansion period, pTTL is ready for administration back into the patient via infusion (4).

Internalisation of antigens with the EpiTCer® technology promotes natural processing and presentation of peptides to T cells.

Unique proprietary tools
Explore the specifics of our two innovative technologies, PIOR® and EpiTCer®, forming the basis of our pTTL therapy. Designed with precision and efficiency in mind, they offer cutting-edge solutions in neoantigen identification and delivery.
PIOR®: Precision in neoantigen identification
Treating cancer poses a complex challenge due to the varied mutations and the resulting neoantigens present in each tumour. For therapy to be effective, it is crucial to target the most relevant mutations. PIOR® streamlines this process by identifying, selecting, and prioritising tumour-specific neoantigens for inclusion in personalised T cell therapy. The system, built on state-of-the-art machine learning, captures the latest in neoantigen prediction and next-generation sequencing. It is not only efficient and accurate but also GDPR-compliant, ensuring alignment with industry quality standards.
To select tumour-specific neoantigens, PIOR® uses state-of-the-art bioinformatic techniques to compare DNA and RNA sequences from tumour cells to those from healthy cells to pinpoint tumour-specific mutations, known as neoantigens (1). PIOR® then employs advanced algorithms and machine learning to conduct a comprehensive analysis of these mutations. It identifies up to 36 of the most optimal tumour-specific neoantigens for each patient, which are then used in the production of personalised EpiTCer® beads (2).

EpiTCer® technology: Carrying the neoantigens
Neogap’s EpiTCer® technology expands and trains the patient’s T cells to target the specific neoantigens derived from the patient’s tumour. Once these neoantigens are identified through our PIOR® system, they are produced and paired with superparamagnetic microbeads, forming patient-specific EpiTCer® beads (1).
Due to their optimal size, EpiTCer® beads are readily taken up by APCs like macrophages or dendritic cells through the process of phagocytosis, essentially ’cell-eating’ (2).
These APCs perceive the antigens attached to the beads as foreign, processing and then displaying the neoantigen peptides on their surfaces. They present the antigens to the patient’s T cells, essentially instructing them on which neoantigens to seek out. As a result, these T cells get activated and multiply (3). After expansion of the cell population, the T cells are formulated and infused into the patient, launching an attack against the tumour (4).
