Advanced/Metastatic
Open-Label Safety and Tolerability Study of INCB057643 in Subjects with Advanced Malignancies
Results Available
Clinical Study Purpose
The purpose of the Study is to select a dose and assess the safety and tolerability of INCB057643 as a monotherapy (Part 1 and Part 2) and in combination with standard-of-care (SOC) agents (Part 3 and Part 4) for subjects with advanced malignancies.
Part 1 will determine the maximum tolerated dose of INCB057643 and/or a tolerated dose that demonstrates sufficient pharmacologic activity. Part 2 will further evaluate the safety, preliminary efficacy, PK, and PD of the dose(s) selected in Part 1 in select tumor types including solid tumors, lymphomas and other hematologic malignancies. Part 3 will determine the tolerated dose of INCB057643 in combination with select SOC agents; and assess the safety and tolerability of the combination therapy in select advanced solid tumors and hematologic malignancies. Part 4 will further evaluate the safety, preliminary efficacy, PK, and PD of the selected dose combination from Part 3 in 4 specific advanced solid tumor and hematologic malignancies.

Protocol Summary
Safety and tolerability of INCB057643 as monotherapy and in combination with standard of care (SOC) agents in patients with advanced malignancies; assessed by clinical laboratory assessments, physical examinations, 12 lead ECGs, and adverse events (AEs)
Timeframe: From screening through at least 30 days after end of treatment, up to approximately 24 months
Pharmacokinetics of INCB057643 as monotherapy in the fasted state and in the fed state (food effect; Part 2 only) and when administered in combination with Standard of Care (SOC) agents in the fasted state assessed by plasma and urine concentrations
Timeframe: Protocol-defined timepoints in treatment Cycle 1 and 2, up to approximately 1 month.
Measurement of cellular myc protein concentrations before and after administration of INCB057643 when administered as monotherapy
Timeframe: PD in plasma at pre-dose and 0.5, 1, 2, 4, 6 and 8 hours postdose, up to approximately 1 month.
Efficacy of INCB057643 when administered as monotherapy and in combination with SOC agents based on the investigator assessment of response using criteria appropriate for each disease in subjects with advanced malignancies criteria
Timeframe: Efficacy measures from screening through end of treatment and follow-up (every 9 weeks), up to approximately 24 months
