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,

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,

Patients on Vemurafenib [Zelboraf] Need Testing for RAS Mutations: Secondary Cancers a Major Concern

January 26, 2012 – A January 20, 2012 article in Medscape Medical New illustrates how personalized medicine can be tricky. The case is Vemurafenib [Zelboraf], which was introduced to the market together with an companion genetic test mid 2011 for the treatment of advanced melanoma in suitable BRAF mutation (V600E) positive patients only.

  • Gene that protects against osteoarthritis identified December 2, 2020
    Osteoarthritis is one of the most common problems associated with aging, and although there are therapies to treat the pain that results from the breakdown of the cartilage that cushions joints, there are no available therapies to modify the course of the disease.
  • Treating brain diseases now possible December 1, 2020
    Neurological diseases of the brain such as dementia, autism and schizophrenia are now a growing social problem. Nevertheless, studies on their definitive cause are still insufficient. Recently, a POSTECH research team has identified the mechanism in which such neurological diseases occur, thus solving the enigma to treating them.
  • Scientists identify new genetic MND risk factor in junk DNA December 1, 2020
    A new genetic risk factor for Motor Neurone Disease (MND), which if treated could halt or prevent the degenerative condition, has been identified in so-called 'junk DNA' by scientists at the University of Sheffield. The newly discovered genetic changes are present in up to one percent of MND patients.
  • Genomic analysis of mako shark reveals genes relating to tumor suppression in humans December 1, 2020
    Anecdotal reports claim that the incidence of cancer in sharks is very low, but there is not enough data to confirm this estimate categorically. A study published in the journal Genomics, however, presents strong evidence of anti-tumor activity in the genome of the Shortfin mako shark, Isurus oxyrinchus.
  • A large-scale tool to investigate the function of autism spectrum disorder genes November 30, 2020
    Scientists at Harvard University, the Broad Institute of MIT and Harvard, and MIT have developed a technology to investigate the function of many different genes in many different cell types at once, in a living organism. They applied the large-scale method to study dozens of genes that are associated with autism spectrum disorder, identifying how […]
