The Clinical and Economic Impact of Inaccurate EGFR Mutation Tests in the Treatment of Metastatic Non-Small Cell Lung Cancer

June 30, 2017 – The below citation from PubMed addresses an vey important issue associated with genetic testing in theragenomic and personalized medicine. It is the question if the genetic test used to stage, classify, or determine treatability of a disease with a given drug is accurate.

Osimertinib (Tagrissa) approved for non-smal cell lung cancer (NSCLC) patient subgroup carrying the EGFR T790M mutation

February 07, 2016 – The European Commission has approved once-daily Osimertinib (Tagrissa) for the treatment of patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) that is positive for the epidermal growth-factor receptor (EGFR) T790M mutation. This follows a positive review in December 2015.

Necitumumab (Portrazza) approved for the treatment of advanced squamous non-small cell lung cancer (NSCLC)

November 28, 2015 – The American Food and Drug Administration (FDA) just approved Necitumumab (Portrazza) in combination with two forms of chemotherapy to treat patients with advanced (metastatic) squamous non-small cell lung cancer (NSCLC) who have not previously received medication specifically for treating their advanced lung cancer.

Theragenomic medicine: FDA approves Osimertinib (Tagrisso) to treat patients with non-small cell lung cancer (NSCLC) who carry the EGFR mutation T790M

November 14, 2015 – The American Food and Drug Administration (FDA) just granted accelerated approval for an oral medication to treat patients with advanced non-small cell lung cancer (NSCLC). Osimertinib (Tagrisso) was approved for patients whose tumors have a specific epidermal growth factor receptor (EGFR) mutation (T790M) and whose disease has gotten worse after treatment with other EGFR-blocking therapy.

FDA Approves Companion Genetic Diagnostic Test for Erlotinib [Tarceva] in NSCLC

May 14, 2013 – The US Food and Drug Administration (FDA) today announced the approval of the cobas EGFR Mutation Test, a companion diagnostic for the cancer drug Erlotinib (Tarceva). This is the first FDA-approved companion diagnostic that can detect epidermal growth factor receptor (EGFR) gene mutations,

  • 30-year study identifies need of disease-modifying therapies for maple syrup urine disease January 24, 2020
    A new study analyzes 30 years of patient data and details the clinical course of 184 individuals with genetically diverse forms of Maple Syrup Urine Disease (MSUD), which is among the most volatile and dangerous inherited metabolic disorders. Researchers collected data on survival, hospitalization rates, metabolic crises, liver transplantation, and cognitive outcome. This represents the […]
  • TP53 gene variant in people of African descent linked to iron overload, may improve malaria response January 24, 2020
    In a study by The Wistar Institute and collaborators, a rare, African-specific variant of the TP53 gene called P47S causes iron accumulation in macrophages and other cell types and is associated with poorer response to bacterial infections, along with markers of iron overload in African Americans. Macrophage iron accumulation disrupts their function, resulting in more […]
  • Scientists highlight potential of exposome research January 23, 2020
    Over the last two decades, the health sciences have been transformed by genomics, which has provided insights into genetic risk factors for human disease. While powerful, the genomics revolution has also revealed the limits of genetic determinants, which account for only a fraction of total disease risk. A new article in the journal Science argues […]
  • Researchers uncover mechanism for how common gene therapy vectors enter cells January 23, 2020
    Researchers led by a team at Massachusetts Eye and Ear have identified a novel cellular entry factor for adeno-associated virus vector (AAV) types—the most commonly used viral vectors for in vivo gene therapy. AAVs are vectors—or vehicles—that are created from a virus that is made harmless by molecular engineering, and have shown promise transporting genetic […]
  • Largest-ever study ties over 100 genes to autism January 23, 2020
    More than 100 genes appear to be involved in autism spectrum disorders (ASD), according to the largest genetic study of the condition to date.
  • More than 40% of status epilepticus patients suffer adverse outcomes January 24, 2020
    A new study published in Seizure gives insight into the short-term outcome of patients treated for status epilepticus in Kuopio University Hospital in Finland. The researchers found a 9% risk of death and a 32% risk of functional loss at one month after status epilepticus. The patient's risk of death could be predicted relatively reliably […]
  • A new twist on quantum communication in fiber January 24, 2020
    New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks.
  • The regulators active during iron deficiency January 24, 2020
    Iron deficiency is a critical situation for plants, which respond using specific genetic programmes. Biologists from Heinrich Heine University Düsseldorf (HHU) and Michigan State University (MSU) used artificial intelligence methods to examine how to predict regulatory genetic sequences. They have now published the findings from their joint research work in the journal Plant Physiology.
  • Brain-cell helpers powered by norepinephrine during fear-memory formation January 24, 2020
    A sustained state of vigilance will generate a different type of memory than a momentary startle, and these differences are linked to distinct signaling molecules in the brains of mice. Researchers at the RIKEN Center for Brain Science (CBS) have visualized these dynamics in the living mouse brain for the first time, observing two molecular […]
  • What goes up may actually be down January 24, 2020
    A new study in Frontiers in Neuroscience used virtual reality to determine how people plan their movements by 'seeing' gravity using visual cues in the landscape around them, rather than 'feeling it' through changes in weight and balance.
