The Urgency of TIL Therapy Improvement

Tumor-infiltrating lymphocyte (TIL) therapy is an increasingly promising approach in cancer immunotherapy, which offers a personalized and potent treatment strategy by harnessing the power of a patient's immune system. However, several challenges remain in its development and clinical application. As a result, it is urgent to discover and develop more efficient and cost-effective strategies to advance TIL therapy development, empowering its expansive application globally.

Our Advanced Immunotherapy Solutions for TIL Therapy Development

Creative Biolabs offers a comprehensive suite of advanced immunotherapy solutions to revolutionize TIL therapy in amplifying anti-tumor effects and overcoming tumor immune evasion. Our solutions include but are not limited to:

Enhanced TIL Isolation and Expansion

Advanced Cell Isolation Technologies: We integrated cutting-edge techniques like microfluidic devices to improve efficiency and purity.
Optimized Culture Conditions: We have successfully innovated a more suitable TIL culture system to enhance TIL expansion and maintain functional activity.
Genetic Engineering: We employ cutting-edge genetic engineering technologies to modify TILs to augment their potency and specificity.

Enhanced TIL Trafficking and Tumor Penetration

Engineered TILs: We apply genetic engineering technologies to introduce homing receptors or chemokine receptors to direct TILs to the tumor site.
Nanoparticle Delivery Systems: We adopt the approach of encapsulating TILs or their activating factors in nanoparticles to improve their delivery to the tumor microenvironment.
Combination Therapies: Combining TIL therapy with other modalities like radiation therapy or chemotherapy to enhance tumor penetration. Furthermore, we provide a combination therapy testing service to evaluate validation and efficiency.

Improved TIL Activation and Persistence

Targeted Activation Signals: We investigate novel activation factors (or combinations) or gene engineering TILs to optimize TIL activation.
Immune Checkpoint Inhibition: Combining TIL therapy with checkpoint inhibitors to enhance anti-tumor activity.
Adoptive Cell Transfer Strategies: Optimizing the timing and dosing of TIL infusion to improve engraftment and persistence.

Overcoming Tumor Immune Evasion

Targeting Immune Suppressive Cells: Eliminating or inhibiting immunosuppressive cells to create a more favorable tumor microenvironment.
Modulating the Tumor Microenvironment: Manipulating the tumor microenvironment to enhance TIL infiltration and activity.
Personalized Immunotherapy: Developing personalized treatment plans based on a patient's tumor characteristics and immune profile.

Advantageously, our robust platform provides a complete therapy development system, enabling us to customize solutions according to specific customer needs. We apply cutting-edge technologies and rigorous quality assurance to achieve high accuracy and multidimensional test findings. Additionally, we offer a variety of in vivo models for preclinical testing and provide model customization services to meet specific research requirements. By leveraging cutting-edge technologies and a deep understanding of immunology, we are dedicated to accelerating the development of effective TIL-based therapies, ultimately improving patient outcomes and transforming cancer treatment.

Testing Models for TIL Therapy Development

Choosing a suitable model is crucial to closely mimic human disease, including tumor type, stage, and immune microenvironment, as well as evaluate the efficacy and safety of TIL therapies before clinical trials. Several models are commonly used:

Syngeneic Tumor Models
Humanized Mouse Models
Patient-Derived Xenograft (PDX) Models

Q & A

Q1: What are the advantages of TIL therapy compared to CAR-T cell therapy?

A1: TIL therapy offers several advantages over CAR-T therapy. TIL therapy offers several advantages over CAR-T cell therapy, such as a broader target range, reduced risk of cytokine release syndrome (CRS), potential for longer-lasting immunity, and reduced risk of neurotoxicity. While both therapies are powerful tools in cancer immunotherapy, TIL therapy's versatility and reduced toxicity profile make it a promising treatment option for a wide range of cancers.

As a leading innovator in immunotherapy, Creative Biolabs is dedicated to advancing TIL therapy. Our team of experts is constantly exploring novel strategies to overcome the limitations of traditional TIL therapy.
