Cost-Benefit Analysis Questions Treating Medicaid Patients with Vemurafenib

The impressive, but still short-term, benefits of vemurafenib for melanoma patients may not justify the hefty cost to a Massachusetts Medicaid program, according to an analysis presented at an American Society of Health-System Pharmacists meeting. Vemurafenib targets the most common mutation of BRAF, which is one of the genes that is most often abnormal in melanomas. The analysis noted that vemurafenib boosted 6-month survival rates over those of the conventional chemotherapy drug dacarbazine (84% and 64%, respectively). However, vemurafenib is also more expensive than dacarbazine, with relative per patient costs estimated at $9,995 and $1,811 per month, respectively.


Alternative Dosing Schedule Could Delay Resistance to Targeted Melanoma Therapy


Treatment with vemurafenib, a drug in the BRAF inhibitor family, results in rapid tumor shrinkage in metastatic melanoma patients with the V600E BRAF mutation. The response lasts for months, but unfortunately, tumors ultimately become resistant to the treatment. Currently, vemurafenib is given as an oral dose on a daily basis. But a new study published in Nature (doi:10.1038/nature11814) suggests that a 4-weeks-on, 2-weeks-off dosing schedule may help to stave off resistance. Continue reading…
