Pheast Presents New Preclinical Data for PHST001, an Anti-CD24 Macrophage Checkpoint Inhibitor, at SITC 2024 (Businesswire) - "The presented data show that PHST001, through potent CD24 binding, promotes macrophage-induced phagocytosis in a number of cancer cells and significantly shrinks tumors in vivo. In addition, PHST001 has a favorable PK profile in non-human primates and does not induce immune-mediated toxicity in vitro....Pheast is on track to initiate clinical trials with PHST001 in the first half of 2025."

Pheast partners with Lonza to produce cancer-gobbling CD24 drug (BioProcess International) - "The company has partnered with contract development and manufacturing organization (CDMO) Lonza to manufacture its drug substance (DS) and drug product (DP), with the cell-line development and DS work done in Visp and the DP work done in Basel, both in Switzerland. That partnership has enabled Pheast to attain the supply needed of its lead drug candidate, PHST001, for first-in-human clinical trials. The drug was developed as a therapeutic against cluster of cell differentiation (CD) 24, a known 'don’t eat me' signal that is highly expressed in ovarian and breast cancers."
