Conditions

Advanced ROS1-positive NSCLC and other advanced ROS1-positive solid tumors

Brief summary

Phase 1 • RP2D and, if applicable, the MTD as determined by incidence of DLTs during Cycle 1, overall safety profile, PK, PD, and preliminary efficacy Phase 2 • ORR per RECIST 1.1.

Detailed description

• Incidence and severity of treatment-emergent adverse events (TEAEs) and changes in clinically relevant laboratory parameters • Pharmacokinetic parameters of NVL-520 − Maximum plasma concentration (Cmax); Cmax – dose normalized, plasma concentration at the end of the dosing interval (Ctau); average plasma concentration (Cavg); time of maximum concentration (Tmax); Please refer to protocol for further end points due to word limitation.
