- Initial safety & efficacy in Urothelial Carcinoma (UC), Esophageal Squamous Cell Carcinoma (ESCC) and Biliary Tract Carcinoma (BTC) patients will be presented from clinical studies evaluating BL-B01D1, an EGFRxHER3 bispecific topoisomerase inhibitor- based antibody-drug conjugate (ADC)
REDMOND, Wash., Sept. 9, 2024 -- SystImmune, Inc. (SystImmune), a clinical-stage biotechnology company, today announced that three abstracts on BL-B01D1, a potentially first-in-class EGFRxHER3 bispecific antibody drug conjugate (ADC) will be presented at the European Society for Medical Oncology (ESMO) Congress 2024 taking place on September 13–17 in Barcelona, Spain. BL-B01D1 is being jointly developed by SystImmune and Bristol Myers Squibb under an exclusive license and collaboration agreement.
Expanded results from clinical trials of BL-B01D1 will include data from patients with advanced stages of Urothelial Carcinoma, Biliary Tract Carcinoma, and Esophageal Squamous Cell Carcinoma and having multiple cycles of prior therapies. The data to be presented at ESMO highlights continued progress in BL-B01D01 clinical development and builds upon the previously reported clinical data in lung and breast cancer patients at ASCO, ESMO and SABCS in 2023.
"These data support our continued conviction that BL-B01D1 has a manageable safety profile and add to the body of evidence that shows encouraging signals of efficacy across a wide variety of tumors" said Jonathan Cheng, M.D., CMO of SystImmune. "This positions BL-B01D1 as a versatile therapeutic option that may address the unmet medical needs of patients with limited treatment options. We are committed to advancing this therapy through clinical trials, exploring its potential not only as a monotherapy but also in combination with other agents, to improve outcomes for cancer patients globally."

About BL-B01D1
The company is developing BL-B01D1, a bispecific antibody-drug conjugate (ADC) that targets both EGFR and HER3. These proteins are highly expressed in most epithelial tumors. The tetravalent BL-B01D1 has two binding domains for distinct Growth Factor Receptors that drive cancer cell proliferation and survival. Inheriting the SI-B001 mechanisms of action, BL-B01D1 blocks EGFR and HER3 signals to cancer cells, reducing proliferation and survival signals. Upon antibody mediated internalization, BL-B01D1 is trafficked to cancer cell lysosomes and liberates its therapeutic payload that induces genotoxic stress activating pathways leading to cancer cell death.
