Science-Driven. Human-Centric.

That's Eisai Oncology.

Despite all the advances the oncology community has seen since 1987 when Eisai came to America, there are still too many people living with cancer, and too many unmet needs remain. That’s why we let the science drive us to new approaches that accelerate progress in oncology, even if it means pursuing breakthroughs in challenging areas unexplored by other companies. Behind that work is our grounding philosophy rooted in empathy, a concept we call human health care (hhc). Our commitment to hhc means that we always prioritize patients and their families above all else. We do what it takes to find the potential in the seemingly impossible, because transformative cancer solutions simply can’t wait.

We Take On Our Work With Resilience, Conviction and Intention.

  • Resilience

    Our quest to find a novel solution

    We searched far and wide to find a breakthrough therapy with the potential to help some cancer patients live longer. Our scientists discovered an organic compound found in the ocean and perfected a unique chemical reaction to synthesize it.

  • Conviction

    Our relentless pursuit to develop a targeted therapy

    When we set out to explore angiogenesis and potential therapeutic applications in 1991, we envisioned the promise of targeted anticancer therapies and were driven by the aim to maximize for patients the benefits that the scientific community hoped they would provide. As our research progressed, we concentrated on diseases with poor prognoses and limited treatment options. Rather than rushing to be first to market, we stayed true to our vision and prioritized how the compound would bind to certain targets implicated in the pathogenesis of the cancer, including its potential to minimize mechanisms of escape and resistance. This led us to create a targeted anticancer agent.

  • Intention

    Achieving more for patients through collaboration

    We’ve made it our mission to get transformative medicines to those who need them the most, and we forge the most effective collaborations to help expedite our mission. With the hope of reaching more patients in need, we are investigating our targeted agent (a multi-receptor tyrosine kinase inhibitor) in combination with an immuno-oncology therapeutic, Merck’s anti-PD-1 therapy. To date, numerous trials have been initiated under our LEAP clinical program, which is evaluating the combination across multiple tumor types.

Our Science-Driven Approach

Exploring the Depths of Human Biology to Find the Next Game Changer and Bring Us Closer to a World Without Cancer

We’ve reimagined the way we approach research and development to maximize our strengths while promoting greater collaboration and varied thinking. This style of working allows us to be nimble, make critical decisions more quickly, and increase efficiencies in our day-to-day work. Our scientists collaborate across functions while following a biology-first approach—and broadening our horizons allows us to consider the science behind more than just oncology. We call this new organization, and the approach that it employs, Deep Human Biology Learning (DHBL). Designed to help guide us toward novel solutions, DHBL is a collaborative effort among all Eisai scientists to harness their diverse experience in the search for novel solutions.
