종양 침윤성 림프구(TIL) 치료법 - 표적 집단, 경쟁 구도, 시장 예측(2034년)

Key Highlights:

• Over the last ten years, cell-based immunotherapy has emerged as a promising approach for treating solid tumors. Tumor-infiltrating lymphocytes, which are lymphocytes found within tumor tissues, have gained attention. Advances in technology have enhanced the methods for isolating and expanding TILs from tumors, and their clinical application in solid tumor treatment has demonstrated encouraging effectiveness.
• TIL therapy has shown success in treating patients with metastatic melanoma and other solid tumors. Unlike other adoptive cell therapies (ACTs) like CAR-T and TCR-T, TIL therapy offers distinct advantages. TILs consist of diverse T-cell receptor (TCR) clones, enabling them to target both shared self-antigens and tumor-specific neoantigens. This broad reactivity allows TILs to better address tumor heterogeneity and potentially improve treatment outcomes.
• TIL therapies are active in multiple indications, including melanoma, cervical cancer, non-small cell lung cancer (NSCLC), endometrial cancer, head and neck squamous cell carcinoma (HNSCC), colorectal cancer, and other solid tumors.
• Iovance's AMTAGVI (lifileucel) is the first and only approved TIL therapy approved by US Food and Drug Administration (FDA) in February 2024 for the treatment of unresectable or metastatic melanoma.
• TIL therapies have a pipeline, with candidates such as OBX-115, BST02, KSQ-001 EX, KSQ-004 EX in early Phase (I/II) trials targeting diverse indications like advanced gastric, gastroesophageal junction and other solid tumors.
• In June 2025, Iovance Biotherapeutics, announced that the Journal of Clinical Oncology has published the final analysis from the Phase II C-144-01 clinical trial evaluating the individualized T cell therapy AMTAGVI in patients with advanced melanoma. These five-year follow-up results are being simultaneously presented during an oral session today at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting.
• Several companies including Iovance Biotherapeutics, Obsidian Therapeutics, Biosyngen, KSQ Therapeutics, and others are currently engaged in the development and production of TIL therapies, which have the potential to significantly impact and enhance the TIL therapies market.

Tumor-Infiltrating Lymphocyte Therapies Disease Understanding and Treatment Algorithm

TIL Therapies Overview

TIL therapy represents an advanced form of adoptive cell therapy (ACT) wherein naturally occurring, polyclonal T cells extracted from a patient's tumor microenvironment are expanded ex vivo and re-infused following non-myeloablative lymphodepletion. Unlike genetically engineered modalities such as CAR-T or TCR therapies, TIL therapy exploits the intrinsic tumor specificity of endogenous lymphocyte populations, which are already primed to recognize a diverse array of neoantigens unique to the patient's tumor.

The therapeutic rationale hinges on the ability of these tumor-resident T cells to mount a more comprehensive and physiologically relevant anti-tumor response. Upon re-infusion, the expanded TILs can persist and traffic to tumor sites, where they mediate cytotoxic activity against malignant cells. This approach has demonstrated durable responses, particularly in immunologically "hot" tumors such as metastatic melanoma, cervical cancer, and NSCLC, even in patient's refractory to immune checkpoint blockade.

The landmark FDA approval of AMTAGVI in 2024 for unresectable or metastatic melanoma marked a pivotal regulatory milestone, establishing TILs as the first approved autologous cell therapy for solid tumors. Despite manufacturing and logistical challenges, particularly around tumor tissue acquisition, scalability, and turnaround times, the clinical potential of TILs in solid tumor indications where other ACT modalities have largely underperformed positions them as a transformative modality in the evolving immuno-oncology landscape.

Marketed Drugs

AMTAGVI (lifileucel): Iovance Biotherapeutics

AMTAGVI is a tumor-derived autologous T cell immunotherapy indicated for the treatment of adult patients with unresectable or metastatic melanoma previously treated with a PD-1 blocking antibody, and if BRAF V600 mutation positive, a BRAF inhibitor with or without a MEK inhibitor. The specific mechanism of action of AMTAGVI is unknown.

The proposed mechanism for AMTAGVI offers a new cell therapy approach that deploys patient-specific T cells called TIL cells. When cancer is detected, the immune system creates TIL cells to locate, attack, and destroy cancer. TIL cells recognize distinctive tumor markers on the cell surface of each person's cancer. When cancer develops and prevails, the body's natural TIL cells can no longer perform their intended function to fight cancer.

In February 2024, Iovance Biotherapeutics announced that the FDA has approved AMTAGVI suspension for intravenous infusion. AMTAGVI is approved under an accelerated approval based on overall response rate (ORR) and duration of response. Iovance is also conducting TILVANCE-301, a Phase III trial to confirm clinical benefit.

Currently, AMTAGVI is also being developed as both monotherapy and combination therapy with pembro for multiple indications like NSCLC, cervical cancer etc. which are in late Phases (III/II) of clinical trials.

Emerging Drugs

OBX-115: Obsidian Therapeutics

OBX-115 is a next-generation, TIL therapy designed using Obsidian's proprietary cytoDRIVE platform. The TILs are genetically engineered to express membrane-bound interleukin-15 (mbIL-15), which supports T cell proliferation, persistence, and antitumor activity without the need for high-dose IL-2, a major driver of toxicity in conventional TIL therapy

OBX-115 TIL are engineered to express mbIL15 fused to a drug-responsive domain, which allows for a dose-dependent increase in functional mbIL15 levels in the presence of an FDA-approved stabilizing drug (acetazolamide [ACZ]), avoiding the need for IL2.

In September 2024, Obsidian Therapeutics announced that the FDA has granted Regenerative Medicine Advanced Therapy (RMAT) designation to OBX-115 for the treatment of patients with unresectable or metastatic melanoma that is resistant to immune checkpoint inhibitor (ICI) therapy.

Tumor-Infiltrating Lymphocyte Therapies Market Outlook

TIL therapies represent a next-generation, personalized immunotherapy approach aimed at harnessing a patient's own immune system to fight solid tumors. These therapies involve isolating and expanding TILs from a patient's tumor, reprogramming them ex vivo, and reinfusing them to generate a targeted immune response. After decades of academic development, the TIL therapy field achieved a major milestone in 2024 with the FDA approval of AMTAGVI, developed by Iovance Biotherapeutics, for the treatment of advanced melanoma. As the first approved TIL-based therapy, AMTAGVI marks a paradigm shift in cell therapy for solid tumors, establishing a foothold in a space traditionally dominated by checkpoint inhibitors and targeted drugs.

AMTAGVI's approval has validated the commercial and clinical potential of TILs and has opened the door for broader investment in the modality. Several companies are now actively developing next-generation TIL products, including OBX-115 from Obsidian Therapeutics, currently in Phase I/II trials for melanoma and non-small cell lung cancer (NSCLC). Other early-stage assets such as BST02 from Biosyngen (in liver cancer), and KSQ-001 EX and KSQ-004 EX from KSQ Therapeutics, are exploring broader applications in HNSCC, pancreatic ductal adenocarcinoma (PDAC), colorectal cancer, and NSCLC, reflecting a growing belief in the platform's adaptability across multiple tumor types.

However, while the clinical promise is evident, the TIL therapy landscape faces notable challenges. Manufacturing complexities, long lead times, the need for specialized infrastructure, and high production costs limit scalability and accessibility. Unlike off-the-shelf immunotherapies, TIL products are autologous and highly personalized, requiring robust logistical coordination. Moreover, competition from more mature immunotherapy modalities like CAR-T and immune checkpoint inhibitors adds pressure for TILs to demonstrate not only efficacy but also operational and cost efficiency.

Despite these hurdles, the pipeline, though still early-stage, continues to evolve, with companies focusing on engineering improvements, automation of TIL expansion, and combination strategies with checkpoint blockade to enhance durability and response rates. The scarcity of approved products, juxtaposed with broadening clinical exploration of AMTAGVI and others, underscores both the nascent stage of the field and its significant potential.
