Tumor lysate, particle-loaded, dendritic cell (TLPLDC) vaccine
The TLPLDC vaccine is a unique type of immunotherapy, both in how it is made and how it is delivered. The vaccine is personalized, meaning it is made from a patient’s tumor and blood. Every patient’s tumor has a unique antigenic profile unlike any other, and dendritic cells found in the blood are the most potent antigen presenting cells in the body. Once TLPLDC is administered, it delivers the patient’s complete repertoire of tumor antigens to the immune system, creating a dual innate and adaptive immune response, activating fighter T cells, and triggering the immune system to recognize, and seek out and destroy any cells containing the antigens and specific mutations from their tumor.
Historically, autologous cancer vaccines have been rather onerous to develop, sometimes taking months between the tumor biopsy and administration. Elios has simplified the process so the time from resection to injection is approximately two weeks. This makes the vaccine highly feasible and will ultimately be easy for community and academic oncologists to adopt into their practices.
The TLPLDC vaccine is currently being studied as a monotherapy and in combination with standard-of-care checkpoint inhibitor therapies in a Phase IIb clinical trial for the treatment of late-stage melanoma at leading academic cancer centers in the United States.
