Bristol-Myers Squibb, Apexigen collaborate to evaluate Opdivo in combo with APX005M in advanced solid tumours
Bristol-Myers Squibb Company and Apexigen, Inc., a clinical-stage biopharmaceutical company, announced a clinical trial collaboration to evaluate Bristol-Myers Squibb’s Opdivo (nivolumab) in combination with Apexigen’s APX005M in patients with advanced solid tumours.
APX005M is an investigational compound that is designed to activate CD40, a key immune co-stimulatory receptor essential to regulating the activation of both innate and adaptive immune responses against cancer.
The proposed collaboration will evaluate the safety, tolerability and preliminary efficacy of APX005M in combination with Opdivo in second-line metastatic NSCLC patients who have failed prior chemotherapy, and in metastatic melanoma patients who have failed prior I-O therapy.
Preclinical data suggest that APX005M mimics the endogenous immune activation process through activation of CD40. A receptor on the surface of antigen presenting cells of the immune system, CD40 plays a fundamental role in the activation of both innate and adaptive immune system mechanisms. Opdivo is designed to overcome PD-1 pathway related immune suppression. The companies will explore the potential of combining these two agents with the goal of effectively activating antigen presenting cells (APC) in the tumour microenvironment, thus driving a more productive and sustained immune response against the tumour.
“Targeting the tumour microenvironment through activation of antigen-presenting cells is a novel approach that we are excited to add to our Immuno-Oncology strategy as we continue to advance research for cancers with limited treatment options,” stated Fouad Namouni, M.D., head of oncology development, Bristol-Myers Squibb. “Our agreement with Apexigen builds on our continued focus to bring forward potential novel combination treatment options for patients with cancer.”
“APX005M has demonstrated immune stimulation in patients with solid tumours in a phase 1 study,” said Xiaodong Yang, M.D., Ph.D., president and CEO of Apexigen. “Based on scientific rationale and demonstrated data, we are excited about the new combination studies with Opdivo and APX005M.”
Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in 57 countries including the United States, Japan, and in the European Union.
APX005M is a novel, humanized investigational monoclonal antibody designed to reverse the systemic immune suppression that typically affects cancer patients. APX005M is designed to activate CD40, a co-stimulatory receptor that is essential for activating both innate and adaptive immune systems.
Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumour immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.
Opdivo’s leading global development programme is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including phase 3, in a variety of tumour types. To date, the Opdivo clinical development programme has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.
In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries, including the United States, the European Union and Japan. In October 2015, the company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic tumour tumour melanoma and is currently approved in more than 50 countries, including the United States and the European Union.
