Zymeworks and ALX Oncology Announce Clinical Collaboration Evaluating Zanidatamab with the CD47 Blocker ALX148 in Patients with Advanced HER2-Expressing Breast Cancer
Vancouver, Canada and Burlingame, California (November 16, 2020) – Zymeworks Inc. (NYSE: ZYME), a clinical-stage biopharmaceutical company developing multifunctional biotherapeutics, and ALX Oncology Holdings Inc. (NASDAQ: ALXO), a clinical-stage immuno-oncology company developing therapies that block the CD47 checkpoint pathway, today announced they have entered into a clinical collaboration to evaluate the combination of Zymeworks’ zanidatamab (formerly ZW25), a HER2-targeted bispecific antibody, and ALX148, a next-generation CD47 blocker, for the treatment of patients with advanced HER2-expressing breast cancer and other solid tumors.
Under the terms of the agreement, Zymeworks will conduct an open label, multi-center Phase 1b study to assess the safety and efficacy of the combination of zanidatamab and ALX148 in a two-part study. The first part of the trial will evaluate the safety of the combination treatment. The second part of the trial will evaluate the safety, tolerability and anti-tumor activity of the combination in separate cohorts of subjects with HER2-positive breast cancer, HER2-low breast cancer, and non-breast HER2-expressing solid tumors.
“In addition to broad anti-tumor activity, zanidatamab’s safety profile supports combination approaches with other therapeutics,” said Diana Hausman, M.D., Chief Medical Officer at Zymeworks. “Our collaboration with ALX Oncology and their CD47 blocker, ALX148, has the potential to further expand the opportunity for zanidatamab to provide benefit to a broader population of patients, including those with advanced HER2-expressing breast cancer.”
Zanidatamab is designed to have multiple mechanisms of action, including immune clearance of HER2-expressing tumor cells by macrophages through antibody-dependent cellular phagocytosis (ADCP). CD47 is a “don’t eat me” signal that acts as a checkpoint inhibitor to macrophages. Cancer cells that express CD47 are resistant to immune clearance even when targeted with therapeutic antibodies. Treatment with zanidatamab plus ALX148 has the potential to increase the immune clearance of HER2-expressing cancer cells by combining a biparatopic antibody capable of binding at higher density than monospecific antibodies with a molecule that blocks CD47 on the same targeted cancer cells.
“We are excited about this collaboration with Zymeworks that combines two promising next-generation anti-cancer agents, a HER2-targeted bispecific antibody with a CD47 blocker, to enhance their potential activity in treating patients with advanced breast cancer,” said Jaume Pons, Ph.D., Founder, President and Chief Executive Officer of ALX Oncology. “ALX148 was designed for safe use in combination to maximize clinical activity with a range of anti-cancer agents. This collaboration builds on the promising anti-tumor activity observed in clinical trials of ALX148 combined with a HER2-targeted therapy in patients with advanced HER2-positive gastric and gastroesophageal cancer.”
Zanidatamab is in advanced clinical development, actively enrolling a pivotal study in patients with previously-treated HER2 gene-amplified biliary tract cancer. In addition, five active Phase 2 programs are underway, and Zymeworks plans to initiate a second pivotal study for zanidatamab as first-line treatment for advanced HER2-positive gastroesophageal adenocarcinomas.
Phase 1 studies of ALX148 have been conducted in combination with tumor antigen targeted antibodies, a checkpoint inhibitor and chemotherapy. Preliminary results from ASPEN-01, the ALX148 Phase 1b study, were presented at the Society for Immunotherapy of Cancer’s 35th Anniversary Annual Meeting [abstract 404]. ALX148 displayed promising initial clinical activity in patients with solid tumors, including advanced HER2-positive gastric and gastroesophageal cancer where ALX148 was well tolerated in combination with an anti-HER2 specific antibody and chemotherapy with no maximum tolerated dose reached. ALX Oncology plans to continue the advancement of ALX148 as a potential treatment for a range of solid tumor indications and is currently also in development in patients with higher risk myelodysplastic syndromes (ASPEN-02).
