Bioequivalence and Safety of Generic Glecaprevir/Pibrentasvir Compared to a Branded Product: A Randomized, Crossover Study in Healthy Volunteers.

This was an open-label, randomized, single-dose, 2-period, crossover clinical trial with an adaptive design to evaluate the bioequivalence and comparative pharmacokinetics of generic glecaprevir/pibrentasvir versus the brand name product in healthy White male and female volunteers under fed conditions. Safety profiles were also assessed. A total of 56 healthy adult volunteers were enrolled and randomly assigned in a 1:1 ratio to receive a single dose of either the generic or reference formulation.

Development and Validation of a High-Performance Liquid Chromatography with Tandem Mass Spectrometry (HPLC-MS/MS) Method for Quantification of Major Molnupiravir Metabolite (β-D-N4-hydroxycytidine) in Human Plasma.

Molnupiravir is an antiviral drug against viral RNA polymerase activity approved by the FDA for the treatment of COVID-19, which is metabolized to β-D-N4-hydroxycytidine (NHC) in human blood plasma. A novel method was developed and validated for quantifying NHC in human plasma within the analytical range of 10-10,000 ng/mL using high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS) to support pharmacokinetics studies. For sample preparation, the method of protein precipitation by acetonitrile was used, with promethazine as an internal standard.

The sCD14-ST predictive value in the development of adverse outcomes in operated colorectal cancer patients (diagnostic study).

Unlabelled: The main aim was to analyze dynamic changes in the level of soluble CD14 subtype (sCD14-ST) in blood serum and assess it as a possible risk factor for the development of systemic inflammatory response syndrome, infectious and inflammatory complications, organ dysfunction, and mortality in operated colorectal cancer (CRC) patients.

Materials And Methods: For the period 2020-2021, 90 operated CRC patients were examined. Patients were divided into two groups: 1 - 50 patients operated on for CRC without acute bowel obstruction (ABO); 2 - 40 patients operated on for tumor ABO caused by CRC.
