Summary
TRE-515 is a first-in-class small molecule inhibitor of deoxycytidine kinase (dCK) that is being developed for oral administration in patients with solid tumors. In cancer cells, rapid and upregulated DNA replication creates high replication stress, as such, cancer cells are more susceptible than normal cells to perturbations in nucleotide metabolism by DNA-targeting treatments such as TRE-515. The Primary objective is too determine the safety and maximum tolerability of TRE-515 when administered orally once daily as a single agent. The secondary objective is to establish a recommended phase 2 dose (RP2D), to characterize pharmacokinetics (PK) and pharmacodynamics (PD) of TRE-515 preliminary evaluation of antitumor activity The exploratory objectives are to evaluate the relationship between TRE-515 exposure and plasma deoxynucleoside concentrations of deoxycytidine (dC), evaluate the relationship between TRE-515 exposure and intracellular dCK on-target knockdown as measured by a [18F]-clofarabine (CFA) positron emission tomography (PET) probe and to evaluate the relationship between TRE-515 treatment and dCK gene expression in archived tumor tissue when available
