  • Publication number: 20240127967
    Abstract: Methods of modeling the in vivo efficacy of drug combinations for the treatment or prevention of viral infection are described. The described methods combine data for single drugs and drug combinations from pharmacokinetic, pharmacodynamic, and viral dynamics models under a series of estimated in vivo drug potencies to provide predictions of the in vivo effects of the drug combinations. These predictions can be used to more accurately select drugs and drug treatment regimens that can be successful in controlling viral infection in animal studies, clinical trials and in medical or veterinary interventions. Also described is a method of treating or preventing filovirus infections using combinations of orally available drugs based on predictions from the modeling methods.

  • Patent number: 11959858
    Abstract: Chronic Kidney Disease (CKD) is characterized by the progressive loss of renal function which eventually leads to End Stage Renal Disease (ESRD). CKD affects roughly 30 million Americans, costs billions of dollars in healthcare spending annually, and leaves thousands of patients reliant on burdensome dialysis treatments while waiting for a transplant. Fortunately, CKD may be controllable if diagnosed early in the disease progression. RAMETRIX™ is a novel public health screening technology for early diagnosis and detection of CKD. This technology uses Raman spectroscopy and chemometrics to analyze the molecular composition of urine and other biological fluids. RAMETRIX™ is a fast, non-invasive, accurate, and inexpensive diagnostic tool that can revolutionize the way healthcare providers detect and treat CKD. The RAMETRIX™ AutoScanner is a system enabling more efficient sample processing in large-scale settings such as hospitals and medical laboratories.
