NUC-7738 boosted PD-1 therapy in kidney and melanoma cancers in early trials, showing promise against treatment resistance.
NuCana reported at the 2025 ESMO Congress that NUC-7738, when combined with PD-1 inhibitors, significantly enhanced tumor cell killing in renal cell carcinoma organoids using patient-derived immune cells.
The preclinical findings, based on ten samples, suggest the drug disrupts RNA polyadenylation and alters gene expression, potentially overcoming immunotherapy resistance.
These results align with early clinical data from the ongoing Phase 1/2 NuTide:701 trial, where NUC-7738 showed a favorable safety profile, tumor shrinkage, and prolonged progression-free survival in PD-1 inhibitor-resistant melanoma patients.
The trial is expanding to include 28 more patients, and NuCana plans to discuss regulatory next steps with the U.S. FDA.
The company believes NUC-7738 may enhance PD-1 therapy across multiple cancers by targeting the tumor microenvironment.
