Treatment of double-refractory metastatic melanoma using tils
A recent patent publication (Publication Number: US20230414662A1) discloses a method for treating double-refractory metastatic melanoma in patients by administering a therapeutically effective population of tumor infiltrating lymphocytes (TILs). The method involves obtaining TILs from a resected tumor, expanding them in a closed system, and administering them to the patient. The patent specifies various scenarios where the metastatic melanoma is refractory to specific treatments like aldesleukin, pembrolizumab, nivolumab, ipilimumab, BRAF inhibitors, and PD-1 or PD-L1 inhibitors, among others. Additionally, the method includes steps for culturing TILs, supplementing with IL-2 and antigen presenting cells, and administering a non-myeloablative lymphodepletion regimen before TIL infusion.
Furthermore, the patent outlines detailed steps for processing TILs, expanding them in a closed system, and administering them to patients with double-refractory metastatic melanoma. The method involves multiple expansions of TILs to generate a therapeutic population, ensuring a significant increase in TIL numbers. It also includes co-administration with other treatments like CTLA-4 inhibitors, BRAF inhibitors, MEK inhibitors, and chemotherapeutic regimens in specific cases. The patent emphasizes the importance of closed systems, specific cytokine combinations in cell culture medium, and lymphodepletion regimens for optimal treatment outcomes. Additionally, the method specifies the use of IL-2 regimens post-TIL infusion and provides a range for the therapeutically effective population of TILs to be administered to patients.
