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, the primary standard of care for TGCT, carries significant risk to patients, including complications from infections and prolonged postoperative care, and frequent relapse. A safe and efficacious pharmacological therapy that can be used alongside surgery remains a significant unmet need. AmMax is uniquely positioned to address this need for patients with TGCT by leveraging the target selectivity and enhanced safety profile of AMB-05X via local intra-articular administration, 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 preparing to enroll patients in the next phase of its clinical development program for tenosynovial giant cell tumor (TGCT) in the third quarter of 2022. Based on robust preclinical data and approved IND, AmMax is also prepared to initiate a Phase 2 clinical study in idiopathic pulmonary fibrosis (IPF).
