T-cell receptor-based therapy: an innovative therapeutic approach for solid tumors

Area of Science:

• Oncology
• Immunotherapy
• Cellular Therapy

Background:

• T-cell receptor (TCR)-based adoptive therapy utilizes genetically engineered lymphocytes to target specific tumor markers.
• This approach requires a multi-step process including patient screening, leukapheresis, product generation, lymphodepletion, and infusion.

Purpose of the Study:

• To review the current technology and early clinical development of TCR-based therapy for solid tumors.
• To identify challenges and outline future directions for enhancing TCR therapy efficacy and safety.

Main Methods:

• Review of existing literature on TCR-based adoptive therapy for solid tumors.
• Analysis of technological advancements and clinical trial data.

Main Results:

• TCR-based therapy involves complex manufacturing and patient preparation, with challenges in product generation and selection.
• The immunosuppressive tumor microenvironment poses a significant barrier to treatment efficacy.

Conclusions:

• Overcoming manufacturing, patient selection, and microenvironment challenges is crucial for advancing TCR-based therapies.
• Future strategies require expanding HLA haplotype compatibility and identifying broader tumor markers for wider patient applicability.
