About TGCT

Tenosynovial Giant Cell Tumor (TGCT), with a worldwide incidence of over 300,000, is a serious and debilitating locally aggressive tumor in which patients can experience severe pain, disability, and diminished quality of life. Surgical resection is the primary standard of care for TGCT, but carries significant risk to patients, including complications, prolonged postoperative care, infections, and frequent relapse.  A safe and efficacious pharmacological therapy remains a significant unmet need.  AmMax is uniquely positioned to address this need in treating TGCT by leveraging the target selectivity of AMB-05X and its enhanced safety profile, while creating a sizable commercial opportunity from improved patient care.

About AMB-05X

A potent monoclonal antibody against CSF1R, AMB-05X represents a therapeutic platform targeting serious macrophage-driven inflammatory, fibrotic and neovascular diseases.  CSF1R, via its binding to two regulatory cytokines, CSF1 and IL-34, is critically involved in the regulation of macrophages and related cells in multiple biological processes across many organ systems, making it an attractive target with broad therapeutic applications.

About AmMax Bio Inc.

AmMax was founded to develop therapies under an exclusive worldwide license from Amgen, Inc. that leverages the diverse and critical roles played by the colony stimulating factor 1 receptor (CSF1R) signaling pathway for macrophage-driven diseases in multiple organ systems. AmMax is enrolling patients in a Phase 2 clinical program for tenosynovial giant cell tumor (TGCT).  Based on robust preclinical proof-of-concept results, AmMax is also planning to initiate a Phase 2 clinical study in idiopathic pulmonary fibrosis (IPF).
