Reveal the unexplored regulators of anticancer immunity
OREGA Biotech translates cancer science into first-in-class monoclonal antibodies that restore the immune system's ability to recognize and destroy tumors.
Transforming cancer science into novel immunotherapies.
OREGA Biotech specializes in the discovery and development of first-in-class monoclonal antibodies for cancer immunotherapy. Our in vivo screening platform discovers and validates novel immune checkpoint inhibitors and regulators of anti-PD-1 response.
Founded in 2010 on the research of our academic co-founders, we establish preclinical proof of concept on new targets, then partner early with larger biotech and pharmaceutical companies.
Our anti-CD39 program has been licensed to Innate Pharma, then partnered with AstraZeneca.

From target discovery to patients
We are developing two first-in-class programs that target the immunosuppressive tumor microenvironment and resistance to anti-PD-1 therapy.

IPH5201 · adenosine pathwayNovel target
Inducing TLS & immunityAnti-CD39 mAb
Phase 2Novel target
PreclinicalBlocking the adenosine switch
Dying tumor cells release ATP, a danger signal that calls the immune system into action. CD39, expressed on regulatory T cells and tumor cells, degrades that ATP into immunosuppressive adenosine — letting the tumor escape.
Our humanized blocking antibody inhibits both membrane-bound and soluble CD39: adenosine production falls, ATP accumulates, and immune-mediated killing of cancer cells is restored.

Building immune hubs inside refractory tumors

Our second program targets an undisclosed regulator of B-cell responses. Releasing this brake promotes germinal center formation and the development of tertiary lymphoid structures (TLS) — organized immune hubs within tumors that are strongly associated with response to immune checkpoint blockade.
The underlying biology is well established, and our lead candidate is a humanized, first-in-class monoclonal antibody.
