AG-858 (autologous heat-shock protein 70 peptide vaccine) is a recombinant cancer vaccine made with tumor-derived heat shock protein 70 (HSP70) peptide complexes. HSP70 associates with antigenic peptides, transporting them into antigen presenting cells (APC) for processing. Tumor-derived HSP70-peptide complexes used in vaccine preparations have been shown to prime tumor immunity and tumor-specific T cells in animal models.

Under normal conditions, heat shock proteins are not found outside the cell. But if a cancerous or infected cell has become so sick that it dies and its membrane bursts, all of the cell’s contents spill out, including heat shock proteins that are bound to peptides. These extracellular HSPs send a very strong ‘dange r signal’ to the immune system, instructing it to destroy the other diseased cells. This is how it works:
Investigated for use/treatment in leukemia (myeloid).

Patent documents usually refer to a drug by its chemical name or development code rather than its generic name, and applications are only published about 18 months after filing — so a newer drug may not appear here yet.
