Eureka Therapeutics

Eureka Therapeutics, Inc. is a privately held, clinical-stage biopharmaceutical company headquartered in Emeryville, California, developing T-cell therapies for solid tumors and hematologic malignancies. The company was founded by Dr. Cheng Liu and is built on two proprietary platforms: E-ALPHA, a high-throughput human antibody discovery engine used to find binders against cancer-specific targets, and ARTEMIS, an engineered T-cell receptor platform (AbTCR) designed to deliver CAR-T-level potency with a reduced cytokine-release profile. Its clinical programs include ET140203 (ARYA-1 in adults, ARYA-2 in pediatrics) and ECT204 (ARYA-3) in advanced liver cancer, alongside a GPC2 ARTEMIS T-cell program for neuroblastoma licensed from the National Cancer Institute. Eureka publishes a corporate website, pipeline and technology overviews, a press-release archive with an RSS feed, and patient-facing trial information; as of this profile it publishes no public developer portal, API documentation, or machine-readable API contract.

Eureka Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Cell Therapy.

Eureka Therapeutics’ developer surface includes engineering blog, support, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
