EpCAM is a type I transmembrane glycoprotein that is uniformly and highly expressed on the membrane of various human epithelial-derived tumors such as esophageal cancer, colorectal cancer, pancreatic cancer, ovarian cancer, lung cancer, gastric cancer, and breast cancer, while its expression in normal tissues is relatively low.
However, due to challenges such as the complex microenvironment of solid tumors and high target heterogeneity, the progress of CAR-T therapy in the field of solid tumors has been limited for a long time.IMC001, with its unique target selection and innovative technical design, has demonstrated good safety and preliminary efficacy in previous clinical trials for digestive system tumors. This newly added indication aims to further explore its clinical application value.
According to the public information from the 2024 ASCO conference, in an investigator-initiated exploratory clinical study (IIT) for advanced gastric cancer: As of March 31, 2024, among 10 patients who had undergone at least one efficacy evaluation, IMC001 infusion demonstrated good safety and a 90% disease control rate (DCR). The low-dose group showed an objective response rate (ORR) of 33.3%, while the medium-dose group achieved an ORR of 40%. In the medium-dose group, three patients survived for over 10 months as of the study cutoff date, with one patient confirmed to have reached PR at week 24 and underwent radical gastrectomy at week 27, surviving for more than 22 months as of the cutoff date.
The approval of this new IND application marks an important step for the product in its clinical exploration, expanding from gastrointestinal tumors to pan-epithelial-derived solid tumors (including but not limited to small cell lung cancer, triple-negative breast cancer, etc.).
Dr. Sun Minmin, founder, chairman and CEO of Immunofoco, said: "The expansion of IMC001 indications is based on Immunofoco Biotechnology's clinical strategy of 'transforming solid tumors into hematological tumors' and further develops the potential therapeutic value of this product. According to the mechanism of action of the EpCAM target and existing clinical research data,IMC001 has the potential to provide new therapeutic directions for the treatment of various epithelial solid tumors, postoperative prevention of recurrence and metastasis, combination with surgery, and conversion surgery."We will steadily advance the registration clinical research."
