Endpoints

Primary: To characterize the safety and tolerability of ETX-19477, the maximum tolerated dose (MTD) and/or RP2D of ETX-19477

Secondary: To assess the preliminary anti-tumor activity of ETX-19477 in participants by measuring disease control rate (DCR) using RECIST v1.1, To assess the preliminary anti-tumor activity of ETX-19477 in participants by measuring duration of response (DOR) using RECIST v1.1, To assess the preliminary anti-tumor activity of ETX-19477 in participants by measuring objective response rate (ORR) using RECIST v1.1, To characterize the pharmacokinetic (PK) profile of ETX-19477 by measuring elimination half-life (t1/2), To characterize the pharmacokinetic (PK) profile of ETX-19477 by measuring maximum blood concentration (tmax), To characterize the pharmacokinetic (PK) profile of ETX-19477 by measuring maximum plasma concentration (Cmax), To further characterize the pharmacokinetic (PK) profile of ETX-19477 by the Area Under the Blood Concentration-Time Curve (AUC0-t, AUC0-inf), Clearance (CL), Volume of Distribution (Vd)
