Safety, PK, PD, Clinical Activity of KT-333 in Adult Patients With Refractory Lymphoma, Large Granular Lymphocytic Leukemia, Solid Tumors

This Phase 1a/1b study will evaluate the safety, tolerability and the pharmacokinetics/pharmacodynamics (PK/PD) of KT-333 in Adult patients with Relapsed or Refractory (R/R) Lymphomas, Large Granular Lymphocytic Leukemia (LGL-L), T-cell prolymphocytic leukemia (T-PLL), and Solid Tumors. The Phase 1a stage of the study will explore escalating doses of single-agent KT-333. The Phase Ib stage will consist of 4 expansion cohorts to further characterize the safety, tolerability and the pharmacokinetics/pharmacodynamics (PK/PD) of KT-333 in Peripheral T-cell Lymphoma (PTCL), Cutaneous T-Cell Lymphoma (CTCL), LGL-L, and solid tumors.
