NCT ID NCT05898399

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new oral drug called ART6043, alone or with another drug (olaparib), in 181 people with advanced or metastatic solid tumors. The goal is to check safety, how the body processes the drug, and whether it can slow tumor growth. It is an early-stage trial, so the main focus is on finding the right dose and seeing if it is safe enough to study further.
