About Estrella Immunopharma

Estrella is a clinical-stage biopharmaceutical company developing CD19 and CD22-targeted ARTEMIS® T-cell therapies to treat cancers and autoimmune diseases. Estrella’s mission is to harness the evolutionary power of the human immune system to transform the lives of patients fighting cancer and other diseases. To accomplish this mission, Estrella’s lead product candidate, EB103, utilizes Eureka’s ARTEMIS® technology to target CD19, a protein expressed on the surface of almost all B-cell leukemias and lymphomas. Estrella is also developing EB104, which also utilizes Eureka’s ARTEMIS® technology to target not only CD19, but also CD22, a protein that, like CD19, is expressed on the surface of most B-cell malignancies.
