Toni English’s medical team was ecstatic. Six weeks after completing an experimental cancer treatment, English visited the Orlando Health Cancer Institute in Florida with her husband to receive the results of her latest scan. The excitement in the room was palpable as her oncologist displayed the images of her lungs before and after treatment. The once prominent tumor in her left lung had completely disappeared. English, who had been battling mucosal melanoma, a rare and deadly form of cancer, was overwhelmed by the news.
Mucosal melanoma is a particularly aggressive form of cancer, with only about a quarter of patients surviving five years after diagnosis. English’s cancer had metastasized to her lungs, kidney, and brain, despite undergoing various treatments such as surgery, radiation, and immunotherapy. Her options seemed limited until she was introduced to a clinical trial for a revolutionary new drug developed by Iovance Biotherapeutics.
The drug, known as lifileucel or Amtagvi, is a living therapy made up of immune cells called T cells. Tumor-infiltrating lymphocyte therapy (TIL therapy) involves extracting cancer-targeting T cells from a patient’s tumor, expanding them in the lab, and reintroducing them into the body. The T cells then target and attack cancer cells, potentially leading to the complete eradication of the disease. This innovative approach showed promising results in clinical trials, prompting the FDA to approve Amtagvi for advanced melanoma.
English was one of the fortunate few who responded positively to TIL therapy. While the therapy did not work for everyone, with only a small percentage experiencing complete remission, nearly a third of patients saw some benefit. The approval of Amtagvi marked a significant milestone in cancer treatment, as it was the first time the FDA approved a T cell therapy for a solid tumor, offering hope to patients with advanced melanoma and other solid tumors.

Understanding TIL Therapy: A Living Drug for Cancer
Expanding the Reach of TIL Therapy: New Horizons in Cancer Treatment
Dr. Steven Rosenberg, a renowned oncologist at the National Cancer Institute, played a pivotal role in pioneering TIL therapy as a cancer treatment. His early experiments with TILs in the late 1980s showed promising results, with tumors shrinking in more than half of participants treated. This groundbreaking work laid the foundation for further advancements in TIL therapy and inspired a new wave of research in the field of cancer immunotherapy.
TIL therapy represents a unique approach to cancer treatment, harnessing the body’s immune system to target and destroy cancer cells. Unlike traditional therapies that rely on surgery, radiation, or chemotherapy, TIL therapy utilizes the patient’s own immune cells to mount a targeted attack on the tumor. By extracting T cells from the tumor, expanding them in the lab, and reintroducing them into the body, TIL therapy offers a personalized and potentially more effective treatment option for patients with advanced cancer.
The approval of Amtagvi for advanced melanoma has opened doors to a world of possibilities in cancer treatment. Researchers are now exploring the potential of TIL therapy in other solid tumors, including breast, pancreatic, and colorectal cancers. Clinical trials are underway to evaluate the efficacy of TIL therapy in these cancers, offering new hope to patients with limited treatment options.
As the field of TIL therapy continues to evolve, researchers are focused on optimizing treatment outcomes and expanding the reach of this innovative approach to cancer treatment. By identifying the patients who are most likely to benefit from TIL therapy and enhancing the effectiveness of T cells, scientists aim to improve outcomes and make TIL therapy more accessible to a broader range of patients.
In conclusion, the approval of lifileucel (Amtagvi) for advanced melanoma represents a significant advancement in cancer treatment. TIL therapy offers a promising new approach to targeting and eliminating cancer cells, providing hope to patients with advanced solid tumors. As researchers continue to explore the potential of TIL therapy in various cancers, the future of cancer treatment looks brighter than ever before.
