Cobimetinib (Cotellic) is now approved as part of a combination treatment with Vemurafenib (Zelboraf) for advanced melanoma

November 13, 2015 – The American Food and Drug Administration (FDA) just approved Cobimetinib (Cotellic) to be used in combination with Vemurafenib (Zelboraf) to treat advanced melanoma that has spread to other parts of the body or can’t be removed by surgery, and that has a certain type of abnormal gene (BRAF V600E or V600K mutation).

Can We Identify Risk for Drug Toxicity?

October 10, 2013 – Very recently, David Kerr, Professor of Cancer Medicine at University of Oxford, in the United Kingdom, and past President of the European Society for Medical Oncology, talked on Medscape (see the video here) about risk-benefit analyses for novel, inventive cancer treatments. See here in italics his statement:

 When we talk about precision medicine and personalized medicine,

Vemurafenib [Zelboraf] Approved Together with a Companion Diagnostic Test by FDA for Advanced Melanoma in BRAF V600E Positive Patients

August 17, 2011 — The US Food and Drug Administration (FDA) has just approved the oral targeted therapy Vemurafenib [Zelboraf] for the first-line treatment of both metastatic and unresectable melanomas. The drug is specifically indicated for patients with melanoma whose tumors have V600E mutations in the BRAF gene. An estimated 50% of patients with melanoma have this type of BRAF mutation,

  • Development and analytical validation of a next-generation sequencing based microsatellite instabili October 18, 2019
    The referenced article describes an assay that has a clinically relevant five-day turnaround time and can be conducted on as little as 20 ng genomic DNA with a batch size of up to forty samples in a single run.
  • Lifestyle is a threat to gut bacteria: Ötzi proves it October 18, 2019
    The intestinal microbiome is a delicate ecosystem made up of billions and billions of microorganisms, bacteria in particular, that support our immune system, protect us from viruses and pathogens, and help us absorb nutrients and produce energy. The industrialization process in Western countries had a huge impact on its content. This was confirmed by a […]
  • Singapore completes whole genome sequencing analysis of multi-ethnic Asian populations October 18, 2019
    A new genetic databank has been established containing the completed whole-genome sequencing (WGS) data of close to 5,000 Singaporeans. Worldwide, WGS is increasingly used in research and healthcare to identify genetic variations using cutting-edge technologies that allow large numbers of individuals to be sequenced rapidly—This new study is the world's largest WGS analysis of Asian […]
  • Researchers quantify limitations of health reports from direct-to-consumer genetic tests October 17, 2019
    Health reports from direct-to-consumer (DTC) genetic tests that use a limited variant screening approach often yield clinical false-negative results, which pose the risk of informing health care decisions based on incomplete information, according to findings presented at the American Society of Human Genetics (ASHG) 2019 Annual Meeting in Houston, Texas.
  • Researchers develop mouse model of human gene involved in Alzheimer's disease October 17, 2019
    In research that helps scientists better understand and explore treatments for diseases like Alzheimer's, scientists have developed a line of mice in which the mouse version of the Alzheimer's-associated MAPT gene has been fully replaced by the human version of the gene. In this new animal model, known as a full gene-replacement model, the MAPT […]
