Detaljeret beskrivelse

This is a Phase 1, open-label, multicentre platform study to evaluate the safety and preliminary antitumour activity of NT-175 in HLA-A*02:01 participants with advanced malignancies that are positive for the TP53 R175H mutation.

Dose Escalation will investigate escalating doses of NT-175 in adult subjects with eligible histologies and will evaluate the safety and MTD and/or RDE/RP2D.

Cohort expansion will further evaluate the safety and preliminary anti-tumour activity at or below the MTD in disease specific histologies and determine the RP2D.

Dose Expansion will further evaluate the preliminary anti-tumour activity and safety of NT-175 at the RP2D in disease specific settings.
