TIL + Pembrolizumab for Melanoma

This trial aims to determine if adding the drug pembrolizumab to cell therapy can effectively shrink melanoma tumors. Researchers are testing this combination to assess its safety and efficacy compared to cell therapy alone. The trial involves individuals with metastatic melanoma of the skin who have undergone at least one previous treatment. Participants will undergo various screenings and treatments, including a hospital stay for chemotherapy and cell infusions. Those who have battled metastatic melanoma and received prior treatment might be suitable candidates for this trial. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to important findings.

The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that patients must have completed any prior systemic therapy at the time of enrollment, which might imply stopping certain treatments. It's best to discuss your specific medications with the trial team.

Previous studies have shown that TIL therapy is safe for patients with advanced melanoma. A review of several studies examined the safety of TIL therapy combined with high-dose aldesleukin (a type of immune therapy) and confirmed its safety for patients.

Pembrolizumab, also tested in this trial, has a well-established safety record. The FDA has approved it for treating advanced melanoma, and it has been used successfully for many years. Some patients experience side effects, such as tiredness or skin problems, but serious side effects are less common.

Researchers are excited about these treatments for melanoma because they harness the power of tumor-infiltrating lymphocytes (TIL), which are immune cells extracted from the patient’s own tumor. Unlike standard melanoma treatments like targeted therapy and traditional immunotherapy, these experimental approaches involve expanding these TILs in the lab and reintroducing them to the patient, potentially enhancing the body’s ability to attack cancer cells. One arm of the trial combines these TILs with pembrolizumab, a well-known immunotherapy drug, to further boost the immune response. This innovative approach could lead to more personalized and effective treatment options for patients with melanoma.

Research shows that tumor-infiltrating lymphocyte (TIL) therapy, which participants in this trial may receive, can help treat advanced skin cancer, known as metastatic melanoma. Studies have found that TIL therapy can shrink tumors in 30% to 50% of patients who have tried other treatments. Another treatment tested in this trial is pembrolizumab. Research indicates that more than one-third of patients with advanced melanoma were still alive ten years after receiving pembrolizumab. Additionally, pembrolizumab helped stop the cancer from worsening in 43% of patients, outperforming treatments like ipilimumab. This trial will also explore the combination of TIL therapy and pembrolizumab, which may enhance their effectiveness, potentially shrinking tumors more effectively.¹⁵⁶⁷⁸
