STELLAR-303: This phase III study is evaluating the effectiveness of a new targeted therapy (XL092) plus immunotherapy (atezolizumab) compared to a different type of targeted therapy (regorafenib) in people with metastatic colorectal cancer (mCRC)A Randomized Open-Label Phase 3 Study of XL092 + Atezolizumab vs Regorafenib in Subjects With Metastatic Colorectal Cancer

Clinical summary

Summary

Eligible participants will be allocated to either the Experimental Arm or the Active Comparator Arm. In the Experimental Arm, participants will receive XL092 (administered orally, daily) plus atezolizumab (administered as a 1200mg IV infusion once in a 3-week cycle). In the Active Comparator Arm, participants will receive regorafenib (administered orally daily at 160mg for the first 21 days of each 28-day cycle).
