Summary

QH101 is an allogeneic TCR-enhanced Vδ2 T cell therapy product engineered to express BTN protein-specific binding elements on the cell surface. This innovative approach harnesses the natural cytotoxic capabilities of Vδ2 T cells while augmenting their ability to recognize BTN proteins, thereby significantly improving tumor cell elimination efficiency. Notably, QH101 is designed without co-stimulatory signal domains or the CD3ζ domain, which prevents T cell exhaustion from overactivation and effectively enhances in vivo persistence. Patients with R/R AML face particularly poor prognoses, with conventional chemotherapy and targeted therapies achieving suboptimal complete remission rates and long-term survival below 10%. Similarly, R/R MDS patients typically demonstrate median overall survival of less than one year (with TP53-mutated cases showing even poorer outcomes of 3-6 months), making clinical trial participation the most viable therapeutic option. The development of effective treatments for R/R AML/MDS presents significant challenges due to:1)The paucity of disease-specific molecular targets;2)The slow progress in drug development. Allogeneic γδ T-cell therapy featuring enhanced TCR functionality and multi-mechanism tumoricidal activity represents a promising investigational approach for addressing R/R AMLMDS. This innovative strategy combines the advantages of: 1)Improved target recognition through TCR enhancement; 2)Multi-faceted tumor-killing mechanisms; 3)Potential for better safety and persistence profiles.
