Abstract Text | BRAF V600 mutations occur in various nonmelanoma cancers. We undertook a histology-independent phase 2 "basket" study of vemurafenib in BRAF V600 mutation-positive nonmelanoma cancers.We enrolled patients in six prespecified cancer cohorts; patients with all other tumor types were enrolled in a seventh cohort. A total of 122 patients with BRAF V600 mutation-positive cancer were treated, including 27 patients with colorectal cancer who received vemurafenib and cetuximab. The primary end point was the response rate; secondary end points included progression-free and overall survival.In the cohort with non-small-cell lung cancer, the response rate was 42% (95% confidence interval [CI], 20 to 67) and median progression-free survival was 7.3 months (95% CI, 3.5 to 10.8). In the cohort with Erdheim-Chester disease or Langerhans'-cell histiocytosis, the response rate was 43% (95% CI, 18 to 71); the median treatment duration was 5.9 months (range, 0.6 to 18.6), and no patients had disease progression during therapy. There were anecdotal responses among patients with pleomorphic xanthoastrocytoma, anaplastic thyroid cancer, cholangiocarcinoma, salivary-duct cancer, ovarian cancer, and clear-cell sarcoma and among patients with colorectal cancer who received vemurafenib and cetuximab. Safety was similar to that in prior studies of vemurafenib for melanoma.BRAF V600 appears to be a targetable oncogene in some, but not all, nonmelanoma cancers. Preliminary vemurafenib activity was observed in non-small-cell lung cancer and in Erdheim-Chester disease and Langerhans'-cell histiocytosis. The histologic context is an important determinant of response in BRAF V600-mutated cancers. (Funded by F. Hoffmann-La Roche/Genentech; ClinicalTrials.gov number, NCT01524978.). |

BRAF V600X | lung non-small cell carcinoma | predicted - sensitive | Vemurafenib | Case Reports/Case Series | Actionable | In a Phase II trial, treatment with Zelboraf (vemurafenib) resulted in an overall response rate of 42% (8/19, 8 partial responses) in patients with non-small cell lung cancer harboring BRAF V600 mutations, with a median progression-free survival of 7.3 months (PMID: 26287849; NCT01524978}. | 26287849 |
BRAF V600X | cholangiocarcinoma | predicted - sensitive | Vemurafenib | Case Reports/Case Series | Actionable | In a Phase II trial, treatment with Zelboraf (vemurafenib) resulted in partial response in 12% (1/8) and stable disease in 50% (4/8) of cholangiocarcinoma patients with BRAF V600 mutations (PMID: 26287849; NCT01524978). | 26287849 |
BRAF V600X | colorectal cancer | no benefit | Vemurafenib | Case Reports/Case Series | Actionable | In a Phase II trial, treatment with Zelboraf (vemurafenib) in colorectal cancer patients with BRAF V600 mutations did not result in clinical benefit, with no patients achieving response, and 50% (5/10) demonstrating progressive disease (PMID: 26287849; NCT01524978). | 26287849 |
BRAF V600X | colorectal cancer | sensitive | Cetuximab + Vemurafenib | Phase II | Actionable | In a Phase II trial, treatment with the combination of Zelboraf (vemurafenib) and Erbitux (cetuximab) resulted in an overall response rate of 4% (1/26), stable disease in 69% (18/26), and a median progression-free survival of 3.7 months in patients with BRAF V600-mutant colorectal cancer (PMID: 26287849; NCT01524978). | 26287849 |
BRAF V600X | thyroid cancer | predicted - sensitive | Vemurafenib | Case Reports/Case Series | Actionable | In a Phase II trial, treatment with Zelboraf (vemurafenib) resulted in an overall response rate of 29% (2/7), with 1 complete response and 1 partial response, in patients with anaplastic thyroid cancer patients with BRAF V600 mutations (PMID: 26287849; NCT01524978). | 26287849 |
