TIL Therapies

GaiaCell develops therapies based on tumor-infiltrating lymphocytes (TILs) as a personalized immunotherapeutic approach for the treatment of solid tumors. Our development is focused on clinical feasibility, process reproducibility, and long-term applicability in real-world clinical settings.

What Are TIL Therapies?

TILs (tumor-infiltrating lymphocytes) are immune cells naturally present within tumor tissue and capable of recognizing tumor antigens. TIL therapy is based on isolating these cells from the tumor, expanding them ex vivo, and re-administering them to the patient to enhance the anti-tumor immune response. TIL therapies represent an important approach, particularly for solid tumors, where other forms of immunotherapy often fail to achieve sufficient clinical efficacy.

WHAT WE ADDRESS

Limitations of Existing Immunotherapeutic Approaches in Solid Tumors

Treatment of solid tumors remains a major clinical challenge due to:

  • heterogeneity of the tumor microenvironment,
  • limited efficacy of certain systemic immunotherapies,
  • immune suppression mechanisms within the tumor,
  • lack of personalized therapeutic approaches.

TIL therapies address these limitations by using the patient’s own, tumor-reactive T cells, enabling a more targeted and biologically grounded therapeutic approach.

OUR APPROACH

TIL Therapies Designed for Translation

We place particular emphasis on balancing the biological efficacy of TIL cells with the practical feasibility of the manufacturing process. Development of TIL therapies at GaiaCell is based on a structured translational approach that integrates:

1
isolation and selection of tumor-reactive lymphocytes
2
optimization of ex vivo expansion
3
adaptation of processes for clinical feasibility and reproducibility

CLINICAL AND STRATEGIC SIGNIFICANCE

Why TIL Therapies Remain a Key Development Pillar

TIL therapies offer:

  • a high degree of personalization,
  • potentially broader target coverage compared to single-target approaches,
  • the possibility of combination with other therapeutic modalities.

Due to these characteristics, TIL therapies represent an important component of future combination immunotherapy strategies.

RAZVOJNE PLATFORME 

Key Development Focus Areas

Ti so:

Use of Naturally Tumor-Reactive Cells

TIL therapies leverage immune cells that are already proven to recognize tumors, reducing the need for artificial redirection of the immune response.

Focus on Solid Tumors

Our development targets indications with significant unmet clinical needs, where personalized cell-based approaches represent a realistic therapeutic opportunity.

Translational Process Optimization

Processes are designed with clinical use, scalability, and long-term integration into clinical practice in mind.

DEVELOPMENT STATUS

Stepwise and Controlled Development

The GaiaCell TIL program is developed within a preclinical and translational framework, with a clear focus on understanding biological mechanisms, optimizing manufacturing processes, and preparing for clinical validation. Details regarding protocols, selection strategies, and expansion methods remain part of a protected development environment and are subject to professional discussion within collaborations.

RAZVOJNI STATUS 

Connection to the Broader R&D Strategy

TIL therapies represent a natural complement to GaiaCell’s CAR-T and exosome development programs. Together, they form a comprehensive portfolio of advanced cell and cell-derived therapeutic platforms designed for diverse clinical challenges and indications.
