Immuno-Oncology

About us

The research engine for our Primary Focus in Immuno-Oncology is based at Tsukuba Research Center in Japan. This engine plays a central role in advancing the creation of innovative cancer therapeutics, by bringing together scientists with diverse backgrounds including pharmacology, chemistry, antibody engineering, pharmacokinetics, and safety under a bio-venture-like agile organizational structure. In addition, we collaborate with Astellas’ various research divisions and have established a robust network of external partners to co-create VALUE for patients diagnosed with various forms of cancer.

As part of this initiative, we established a Tumor MicroEnvironment imaging and interactive research for innovation (TME iLab) open innovation hub in Kashiwa-no-ha, a center of life science in Japan, to promote defining characteristics of the tumor microenvironment in clinical samples, selecting biomarkers for effective therapies from clinical data, and identifying candidate target molecules that will become new therapeutic targets.

Our Approach

We focus on the development of multifunctional modality platforms that enable simultaneous stimulation of multiple steps in the cancer immune cycle (Fig. 1). We are actively forming strategic alliances with world-leading research institutes and companies in the immuno-oncology field and have successfully built a robust and competitive pipeline (Fig. 2). We are also strengthening collaboration within Astellas at  Xyphos in San Francisco, CA (a cancer cell therapy leader) and our cancer translational science team in Cambridge, MA to jointly address next generation immuno-oncology therapeutics based on our deep understanding of the tumor microenvironment.

Akihiro Ohashi, Ph.D.

Principal Investigator

Akihiro Ohashi, Ph.D.
Division Head, Exploratory Oncology Research & Clinical Trial Center, National Cancer Center
Affiliate Associate Professor, Graduate School of Frontier Science, The University of Tokyo
Affiliate Associate Professor, Research Institute for Biomedical Sciences, Tokyo University of Science

Dr. Ohashi is an expert in tumor biology and drug discovery. Starting his career as a cancer researcher in post-doc, he investigated molecular functions of tumor suppressor genes in familial breast and ovarian cancers at Mayo Clinic. He then joined Takeda Pharmaceutical Company Ltd. and worked there for 12 years to lead multiple drug discovery projects. In September 2018, he joined National Cancer Center Japan as a Division Head in Exploratory Oncology Research & Clinical Trial Center (NCC EPOC). He currently drives both basic and translational projects, aiming development of novel cancer therapeutic drugs, in collaborations with world-wide academia, pharmaceuticals, and biotech companies. In February, 2023, he was also appointed as a Principal Investigator of Immuno-Oncology at Astellas.
