New Patents Issued and Fast Track Designation Support Development of the Only Locally-Administered Drug Treatment for TGCT
Positive Proof-of-Concept Results Lead to Extension of Phase 2 Study to Optimize Dosing Regimen for Phase 3 Design
REDWOOD CITY, Calif., Sept. 26, 2022 (GLOBE NEWSWIRE) -- AmMax Bio, Inc. (“AmMax”), a private clinical-stage biopharmaceutical company developing innovative therapeutics in oncology, including targeting the colony-stimulating factor 1 receptor (CSF1R), today announced a program update on AMB-05X, the only pharmacological treatment administered locally and directly at the tumor site for tenosynovial giant cell tumor (TGCT).
“In recent months, the AmMax Bio team achieved a number of milestones in advancing our potentially best-in-class therapy, AMB-05X, for the treatment of TGCT,” said Larry Hsu, Ph.D., Chief Executive Officer of AmMax Bio. “We have demonstrated that the local injection of AMB-05X directly to the tumor site yields good clinical efficacy while minimizing the side effects of systemic treatments. Our primary market research shows that physicians who generally do not prescribe systemic drugs with safety warnings and patient monitoring requirements have a very strong interest in the potential for locally administered AMB-05X to improve the standard of care for TGCT and significantly reducing unacceptable side effects. With the expansion of the AMB-05X program, we have also grown our network of TGCT experts and the feedback we continue to receive, particularly from orthopedic oncologists, reaffirms our confidence that AMB-05X could become an important new treatment for this indication.”
“Now, with Fast Track designation affirming the benefits of AMB-05X and newly issued patents protecting our novel formulation, AmMax is initiating the dose optimization phase of its Phase 2 program with a treatment duration of six months. Patients experienced positive clinical outcomes and continuous improvement through twelve weeks of dosing and beyond, and we believe that patients will see greater benefit at six months with AMB-05X than any other pharmacological option.”

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 and granted Fast Track designation by the FDA for TGCT, 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.
