- Companies will combine their unique scientific and technical expertise to develop a first-in-class anti-SIRPα antibody conjugated to TLR9 agonist (“SIRPα TRAAC”) that delivers targeted immune activation
- ALX expands anti-cancer therapeutics pipeline targeting the CD47 checkpoint pathway
- Collaboration extends Tallac’s pipeline of next generation immunotherapies derived from its Toll-like Receptor Agonist Antibody Conjugate (“TRAAC”) platform
BURLINGAME, CA, USA I March 04, 2021 I ALX Oncology Holdings Inc. (“ALX Oncology”) (Nasdaq: ALXO), a clinical-stage immuno-oncology company developing therapies that block the CD47 checkpoint pathway, and Tallac Therapeutics, Inc. (“Tallac”), a privately held biopharmaceutical company harnessing the power of innate and adaptive immunity to fight cancer, today announced a collaboration to jointly develop, manufacture, and commercialize a novel class of cancer immunotherapeutics. Under the terms of the agreement, ALX Oncology and Tallac will share equally in the cost of research and development and any profits or losses incurred.
The collaboration builds on ALX Oncology’s expertise in developing therapies that block the CD47 checkpoint pathway and expands its immuno-oncology pipeline. The collaboration also extends Tallac’s pipeline of next generation immunotherapies derived from its novel Toll-like Receptor Agonist Antibody Conjugate (“TRAAC”) platform. The companies will leverage their respective scientific and technical expertise to advance an anti-SIRPα antibody conjugated to a Toll-like receptor 9 (“TLR9”) agonist for targeted activation of both the innate and adaptive immune systems.
“We are excited to partner with ALX Oncology in the development of next-generation breakthrough cancer immunotherapies,” said Hong I. Wan, Ph.D., President, Chief Executive Officer and co-founder of Tallac. “TLR9 agonists are a class of immunotherapy that generate both innate and adaptive immune responses which may produce robust and durable anti-cancer immunity for patients with advanced-stage cancers. While intratumoral TLR9 agonists have clinically validated this pathway, systemic administration has been unsuccessful, limiting clinical utility in broader patient populations. With Tallac’s TRAAC technology, we now have a way to target this pathway systemically, which could expand the clinical benefit to a much broader patient population. To date, we have generated promising preclinical data with multiple TRAAC molecules that demonstrates the potential of this pathway. The goal of our collaboration with ALX Oncology is to advance SIRPα TRAAC, a systemically delivered TLR9 agonist targeting dendritic cells via SIRPα receptors, enabling a powerful innate and adaptive anti-tumor immune response.”
“Collaborating with Tallac and their novel TRAAC platform broadens ALX Oncology’s therapeutic strategies to activate the innate immune system and SIRPα TRAAC complements our lead product candidate, ALX148,” said Jaume Pons, Ph.D., Founder, President and Chief Executive Officer of ALX Oncology. “While ALX148 is an antagonistic molecule designed to maximize the activity of a wide array of anticancer agents by the blockade of the CD47 myeloid checkpoint, SIRPα TRAAC is an agonistic molecule that directly activates dendritic cells and enables a coordinated innate and adaptive immune response against cancer. Since SIRPα is expressed on both dendritic cells and a range of tumor types, SIRPα TRAAC may enable an effective immune activation response in advanced cancer settings. We are excited about this potentially transformative approach and the possible benefits to patients that are in need of new treatment options.”
About ALX Oncology
ALX Oncology is a publicly traded, clinical-stage immuno-oncology company focused on helping patients fight cancer by developing therapies that block the CD47 checkpoint pathway and bridge the innate and adaptive immune system. ALX Oncology’s lead product candidate, ALX148, is a next generation CD47 blocking therapeutic that combines a high-affinity CD47 binding domain with an inactivated, proprietary Fc domain. ALX148 has demonstrated promising clinical responses across a range of hematologic and solid malignancies in combination with a number of leading anti-cancer agents. ALX Oncology intends to continue clinical development of ALX148 for the treatment of a range of solid tumor indications as well as MDS and AML. For more information, please visit www.alxoncology.com.
About Tallac
Tallac Therapeutics is a privately held biopharmaceutical company harnessing the power of innate and adaptive immunity to fight cancer. Tallac’s pipeline of immunotherapy candidates are derived from the company’s novel Toll-like Receptor Agonist Antibody Conjugate (TRAAC) platform to deliver a potent Toll-like receptor (TLR9) agonist (T-CpG) for targeted immune activation via systemic administration. Several TRAAC molecules are in various stages of discovery and preclinical development. For more information, please visit www.tallactherapeutics.com.
