The Phase 1 part of the study is a dose escalation of STP938 as monotherapy. The Phase 2 part of the study is cohort expansion of STP938 as a monotherapy in 5 different B and T cell lymphomas.
The drug STP938 is an inhibitor of an enzyme called cytidine triphosphate synthase 1 (CTPS1). CTPS1, and a very similar enzyme cytidine triphosphate synthase 2 (CTPS2), control the final step in the production of the cytidine triphosphate (CTP). CTP is an essential building block of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Studies of people with inherited mutations of the CTPS1 gene indicate that certain types of blood cells required CTPS1 in order to divide rapidly, whereas other cells in the body use the CTPS2 enzyme. Based on these observations, it is expected that blocking C…
