Taking Cancer Treatment Beyond the Limits of Immunotherapy

About Amphivena Therapeutics

Amphivena Therapeutics, Inc. is a clinical-stage, immuno-oncology company with a novel platform of T cell engagers (Amphivena ReSTORE™) that directly targets myeloid derived suppressor cells (MDSC), thus relieving cancer-induced immune suppression while controlling cytokine release syndrome (CRS).


Our science and platform address major limitations in cancer immunotherapy

Cancer-associated immune suppression and CRS are major limiting factors in current immunotherapy. MDSC actively inhibit T cell responses in cancer patients and promote immune suppression in solid tumors. They are also significant producers of pathologic CRS-promoting myeloid cytokines, such as IL6.


Our molecules deplete MDSC resulting in the activation and expansion of anti-tumor T cells, without causing CRS, in both immune sensitive and insensitive cancers.


AMV564, Amphivena’s lead molecule, is a clinical stage T cell engager that is highly potent and selectively binds to MDSC while sparing other myeloid cells such as monocytes and neutrophils, activating and expanding anti-tumor T cells in cancer patients. Other platform molecules are trispecific and target tumor antigens in addition to MDSC, providing direct tumor cell killing while combatting immune suppression and restoring anti-tumor immunity.


ReSTORE molecules have prolonged pharmacodynamic activity and are delivered subcutaneously (SC) at home via pre-filled syringe. The dosing route and regimen of these molecules is patient-friendly and highly compatible with other therapies (e.g. checkpoint blockade, CAR-T, vaccines).


SC administration serves as a mechanism for effective delivery of our molecules to the lymphatics, the brain center of the immune system, where T cell education and metastatic spread occur. MDSC accumulate in the lymphatic system where they suppress the generation of anti-tumor T cells. By removing MDSC with ReSTORE molecules, the anti-tumor T cells are relieved from their immune suppressed status, allowing them to migrate to tumors and kill tumor cells.
