Biomarker plan – PI3K disorders

Byscientist

From the public pipeline, it appears that the interest is in vascular anomalies

Hence the biomarker plan would be the following:

  • PD Biomarker and longitudinal disease measurements: Create a sensitive ctDNA/ddPCR assay for mutant PIK3CA detection
  • Target engagement panel for PI3K pathway inhibition: pAKT, pS6, insulin/glucose signaling markers, and inflammatory mediators in blood.
  • Link PK and biomarker data: drug exposure, pathway suppression, and clinical improvement
  • Imaging studies: Link biomarker changes to MRI-based lesion volume reduction or other objective measures
  • Develop functional clinical biomarkers: Evaluate pain scores, bleeding events, swelling, mobility, and quality-of-life measures (PRO) to identify clinical indicators of treatment benefit.
  • Explorations :a) Establish a longitudinal bio-repository b) Identify biomarkers associated with responders c) Confirm PIK3CA mutation subtype (H1047R, E542K, E545K, etc.) to determine whether mutation burden = disease severity or treatment response. d) Characterize enrolled patients from other studies
  • ETC: Learn the current status of Translational medicine ( assays, biomarkers, sample collected etc) Personnel management, Operational (vendor contracts, negotiation) and plan for future

    How does a hospital measure the acuity of an illness? Acuity is defined loosely as the severity of an illness. The more severe an illness or malady is the more attention it deserves. For example, chest pain is critical and deserves attention vs. flu like symptoms do not deserve as much attention. A doctor in…

    Biomarker database There are several databases that are used to track biomarkers. The important thing to keep in mind is that the biomarker may be biological entity like a protein, lipid or DNA/RNA fragment but they can also be a group of cells – for example Tumor infiltrating cells or, physiological test, clinical outcome measure…

    Default mode network

    Byscientist

    When we are not focused on a task, mind-wandering or just idling, specific regions of the brain such as medial pre frontal cortex, angular gyrus, hippocampus become activated and are called the default mode network. This is thought to be important for self referential thought, memory and future planning. It has been mapped with resting…
