Clinical Trial Summary

This study is an open-label, multi-arm, parallel cohort, dose validation and expansion design. The study is modular in design, allowing evaluation of the safety, efficacy and pharmacokinetics (PK) of NUC-3373 in combination with other agents for the treatment of patients with different tumour types. Each module is designed to evaluate a different NUC-3373 combination and consists of a dose-validation phase (Phase Ib) and a dose-expansion phase (Phase II). Phase Ib of each module will determine the safety and tolerability of the combinations for further clinical evaluation in Phase II. Approximately 6-20 evaluable patients will be enrolled in the Phase Ib stage of each module to determine safety, tolerability, and preliminary efficacy of NUC-3373 in combination with other agents. Each module will then move into Phase II to enable a further assessment of safety and efficacy in approximately 20-40 patients. Module 1 will assess NUC-3373 + leucovorin (LV) in combination with pembrolizumab for the treatment of patients with advanced/metastatic solid tumours who have progressed on ā‰¤2 prior therapies for metastatic disease, that may have included 1 prior immunotherapy-containing regimen (either monotherapy or in combination with chemotherapy) or who have not progressed but where addition of NUC-3373 + LV to standard pembrolizumab monotherapy may be appropriate (e.g., patients who could not tolerate post- immuno-oncology (IO) standard of care therapy). Module 2 will assess NUC-3373 + LV in combination with docetaxel for the treatment of patients with advanced/metastatic non-small cell lung cancer (NSCLC) or pleural mesothelioma who have progressed on, or were unable to tolerate, 1 or 2 prior lines of cytotoxic chemotherapy-containing regimens for advanced/metastatic disease. The opening of each module will be at the discretion of the Sponsor. Further modules may be added as non-clinical and clinical data become available to support additional NUC-3373 combinations and tumour types.
