Description
In this Phase II pilot study (NCT00405587) of BRAF V600 inhibitor vemurafenib in 21 metastatic colorectal cancer (CRC) patients with BRAF V600E, one patient had a durable 21 week partial response, and seven patients had 8 week stable disease as best response. Median progression free survival was 2.1 months and median overall survival was 7.7 months. The authors conclude that single agent vemurafenib did not show meaningful activity in V600E CRC, in contrast to the significant vemurafenib activity against V600 in melanoma.
