Next-generation T-cell engager (TCE) specialist Cytospire Therapeutics Ltd. has raised £61 million (US$82.7 million) in a series A round, equipping it to advance the lead program CYT-X300 to the clinic in the treatment of EGFR-positive solid tumors. The company’s pan gamma delta (γδ) TCEs are designed to overcome problems with cytokine release syndrome, on-target effects on healthy cells, and the excessive activation of CD3 that have occurred with earlier bispecific antibodies that bind to the CD3 receptor on T cells.

Beone Medicines Ltd. gained an exclusive option to develop cancer immunotherapy HH-160 worldwide in a deal potentially worth more than $2 billion for Huahui Health Ltd., the developer of the trispecific antibody.

Hypersialylation in tumor cells is a potent mechanism of tumor immune evasion, pushing cancer progression by suppressing both innate and adaptive antitumor immunity. Shanghai Henlius Biotech Inc. has developed an engineered human sialidase enzyme fused to an anti-B7-H3 nanobody, named E-688 or HLX-316, that improves tumor desialylation, durability and efficacy both in vitro and in vivo, while maintaining a safe profile.

The MTHFD enzyme family is central to one-carbon metabolism, with MTHFD2 showing cancer-selective overexpression linked to poor prognosis. Emerging data also identify MTHFD1 as a therapeutic vulnerability in select tumors, supporting MTHFD-targeted drug development.
