Nutcracker Therapeutics Demonstrates Enhanced Functional Activity of Prostate Cancer Candidate NTX-470 at the 2024 AACR Annual Meeting
Of these, NTX-470 showed the strongest target cell killing activity – it was capable of engaging CD3 T cells, while displaying minimal activity in the absence of STEAP1- or PSMA-expressing target cells, retaining low bystander activity.

- LIGHT comes in two forms: membrane-bound or soluble, with the former generally having stronger activity, leading to the hypothesis that limiting membrane shedding would enhance advantageous activity.
- Nutcracker’s scientists engineered multiple variants of LIGHT with either flexible or rigid linkers in place of protease-sensitive sites, to explore how membrane shedding susceptibility affects immunomodulatory activity.
- Of the tested designs, membrane-stabilized variants of LIGHT enhanced HVEM stimulation over WT LIGHT and increased proinflammatory cytokines in the tumor microenvironment.
