Summary
Brief summary
The study will be conducted in 4 parts and will commence with dose escalation of AMX-500 as a
monotherapy (Part 1), followed by monotherapy dose expansion (Part 2).

- Part 1 (Monotherapy Dose Escalation): Single-agent AMX-500 dose escalation

- Part 2 (Monotherapy Dose Expansion): Single-agent AMX-500 dose expansion

The study may subsequently continue via a protocol amendment with dose escalation of AMX-500
combinations (Part 3) followed by combination therapy dose expansion (Part 4).
