Use of t cell engager proteins in the treatment of cancer
By using T-cell adaptor proteins that specifically bind to CD3 and DLL3 and employing a stepwise dosing regimen, combined with chemotherapy and immunotherapy, the problem of poor treatment outcomes in advanced neuroendocrine tumors has been addressed, resulting in safer and more effective treatment and extended survival.

AI Technical Summary
Existing treatments for advanced neuroendocrine tumors (such as small cell lung cancer, large cell neuroendocrine carcinoma of the lung, and extrapulmonary neuroendocrine carcinoma) are not very effective, lack effective early detection methods, and existing treatment regimens have significant side effects, making it difficult to prolong patients' survival.
By employing T-cell adaptor proteins that specifically bind to CD3 and DLL3, a stepwise dosing regimen is used to gradually increase the dose to reduce the occurrence of cytokine release syndrome, achieving high-dose treatment. This, combined with chemotherapy and immunotherapy, enhances the therapeutic effect.
It significantly improved the treatment efficacy for DLL3-positive cancers, reduced treatment side effects, prolonged patient survival, and provided a more effective treatment option.
