In addition to pancreatic cancer, PSCA is expressed in several other solid tumor indications, including: gastric, esophageal, cholangiocarcinoma, glioblastoma, prostate and bladder cancers. The Company plans to expand the clinical development of BPX-601 to include additional PSCA expressing cancer types. About BPX-701 BPX-701 is a high affinity T cell receptor product candidate designed with the CaspaCIDe ® safety switch. It is currently being tested in a Phase 1 study of patients with refractory or relapsed acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) who test positive for PRAME, or preferentially expressed antigen in melanoma. In preclinical studies, PRAME-specific clones showed high reactivity against a panel of PRAME positive tumor cell lines, metastatic melanoma, sarcomas and neuroblastoma tissues.
