Vemurafenib Extends Life up to 3 Years in Melanoma Trial

An ongoing clinical trial found that 26% of melanoma patients treated with vemurafenib (Zelboraf®) were alive at 3 years—far longer than the average survival time of 9 months with conventional chemotherapy. Vemurafenib is a BRAF inhibitor and this trial includes 32 people with the most common BRAF mutation (V600E). In addition, five people survived at 3 years and 4 months; three of them had no evidence of disease.


German Health Institute Says Ipilimumab Benefits Melanoma Patients

Melanoma patients live longer when treated with ipilimumab than with an experimental tumor vaccine called gp100, according to a study by the German Institute for Quality and Efficiency in Health Care. People treated with ipilimumab lived 10 months, while those who were not lived 6.5 months. In addition, ipilimumab did not make people’s quality of life worse. People had the same symptoms—nausea, vomiting, digestive disorders, fatigue, and pain—whether they were treated with the drug or with a placebo.

Combination Statin and Kinase Treatments Promising in Cultured Melanoma Cells

A new drug combination could treat melanomas that resist therapy with a single drug, suggests research that appeared in Cancer Discovery on melanoma cells grown in the laboratory. The researchers tested melanoma cells that had BRAF mutations and resisted treatment with the BRAF inhibitor vemurafenib, and that had NRAS mutations, which resist many treatments. The most effective combination treatment was statins, which are commonly used to treat high cholesterol, but can also kill melanoma cells, and drugs that inhibit proteins called cyclin-dependent kinases, which are involved in cell division.

Sorafenib Fails to Increase Survival in Melanoma Trial

Despite promising results from small trials, a large clinical trial found that combining sorafenib with chemotherapy was no better than chemotherapy alone for melanoma patients. Sorafenib is FDA-approved for kidney and liver cancer that targets tumors by inhibiting the new blood vessels that help them grow and spread. However, this Journal of Clinical Oncology study also showed that the carboplatin/paclitaxel chemotherapy was surprisingly effective. This chemotherapy combination is now listed as a standard melanoma treatment by the National Comprehensive Cancer Network guidelines.

New Clinical Trial to Determine if PV-10 Boosts Immune System

The experimental drug PV-10, which is injected directly into melanoma tumors, may work partly by boosting the immune system. To find out, researchers are launching a clinical trial to see if patients treated with PV-10 have immune biomarkers in their tumors and blood. The study will enroll up to 15 patients.
