Amivantamab monotherapy demonstrated promising, durable antitumor activity in chemorefractory mCRC, regardless of prior anti-EGFR therapy and the primary tumor location. The amivantamab safety profile in mCRC is consistent with experience in NSCLC. Amivantamab plus chemotherapy is currently being explored in two phase III studies in first-line and second-line mCRCs.
While the primary end point of best ORR was not met in this nonrandomized clinical trial, amivantamab was well tolerated, and most patients exhibited disease stabilization. ClinicalTrials.gov Identifier: NCT05074940.
