About Cero Therapeutics

Biological Products, (No Diagnostic Substances), SIC 2836

CERo Therapeutics Holdings, Inc. is a clinical-stage biotechnology company focused on developing genetically engineered cellular immunotherapies for cancer treatment. The company designs Chimeric Engulfment Receptor T cell therapies, known as CER-T cells, which integrate characteristics of innate and adaptive immune responses to target and eliminate cancer cells. Its primary product candidate in development is CER-1236. Because its candidate therapies remain in early clinical or preclinical stages, the company has not yet commercialized any therapies, meaning its potential future customers will consist of cancer patients and healthcare providers upon regulatory approval.

The company operates in the United States and has no commercial products or physical retail stores. It conducts its research and clinical development through third-party contract development and manufacturing organizations, contract research organizations, and suppliers. CERo Therapeutics maintains its principal executive offices and headquarters in South San Francisco, California.
