Summary
Brief summary
The primary objective of this study is to:

* Evaluate the safety and tolerability of AMG 305 in adult participants
* Determine the optimal biologically active dose (OBD), at or below the maximum tolerated dose (MTD) with MTD 1 as the maximum tolerated starting dose and MTD 2 as the maximum tolerated target dose
* Determine the recommended phase 2 dose (RP2D)
