Study Details

Study Description

Brief Summary

This is a first-in-human (FIH) study to explore the safety, tolerability and pharmacokinetics of PA after oral ascending dose administration to healthy male volunteers.

Condition or Disease Intervention/Treatment Phase
  • Drug: Potentiator of antibiotics (PA)
  • Other: Placebo PA
Phase 1

Detailed Description

The first-in-human dose (FHD) trial is a randomized, double-blind, placebo-controlled, dose-escalation trial assessing safety, tolerability and pharmacokinetics (PK) of single and multiple oral doses of PA in healthy male subjects.

The study consists of two stages: single dose administration and multiple dose administration.

The single dose administration stage includes 5 cohorts, multiple dose administration stage includes at least 4 cohorts (groups). Each cohort includes 8 subjects (6 active drugs and 2 placebos). Cohorts intake ascending doses of study drug. The dose of 1st cohort is 1,0 mg/ml, the doses for the following cohorts will be estimated by the Data Monitoring Committee based on pharmacokinetics and safety results of previous group.

For each subject study includes screening period, one baseline period on Day -1, a treatment period (1 day - at single dose stage; 14 days - at multiple dose stage), followed by safety, PK, assessments up to 72-96 hours post dose. Follow-up visits will take place on Day 7 ; 30; 60 (single dose stage) and 30; 60; 90 (multiple dose stage).

      The level of bilirubin is measured in the blood by the bilirubin blood test. Direct bilirubin is water-soluble form of bilirubin. Indirect bilirubin is fat-soluble form of bilirubin. Direct and indirect are measured solely. Total and direct bilirubin levels can be measured from the blood, but indirect bilirubin is calculated from the total and direct bilirubin. It is measured in μmol/L. Normal range for the study: 8,6-20,5 μmol/L.

      Serum creatinine is measured in the blood. Creatinine measurements are used in the trial as the indicator of kidney function. Elevated creatinine level signifies impaired kidney function or kidney disease. As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance of creatinine by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys. It is measured in μmol/L. Normal range for the study: ≤133 μmol/L.

    37. Change in Alkaline phosphatase [Single dose intake: Screening visit; before dose (Day -1); Day 1 - after dose (3 hours); Days 2;7;30;60. Multiple dose intake: Screening visit; before dose (Day -1); Days 1; 3;10;14-after dose (3 hours); Days 17;30;60;90]

    38. Change in Blood Urea Nitrogen [Single dose intake: Screening visit; before dose (Day -1); Day 1 - after dose (3 hours); Days 2;7;30;60. Multiple dose intake: Screening visit; before dose (Day -1); Days 1; 3;10;14-after dose (3 hours); Days 17;30;60;90]

      The amount of urea nitrogen is measured in the blood. The urea is produced by liver in the urea cycle as a waste product of the digestion of proteins. The elevated levels of Blood Urea Nitrogen may be a sign that that kidneys aren't working efficiently. The accumulation of urea and other nitrogen-containing compounds in the blood due to renal failure leads to uremia. The main causes of an increase in Blood Urea Nitrogen are: high protein diet, decrease in glomerular filtration rate (suggestive of renal failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage,[4] fever, and increased catabolism. Hypothyroidism can cause both decreased glomerular filtration rate and hypovolemia, but Blood Urea Nitrogen -to-creatinine ratio has been found to be lowered in hypothyroidism and raised in hyperthyroidism. It is measured in mmol/L. Normal range for the study: ≤8.3 mmol/L.

    39. Change in Uric acid [Single dose intake: Screening visit; before dose (Day -1); Day 1 - after dose (3 hours); Days 2;7;30;60. Multiple dose intake: Screening visit; before dose (Day -1); Days 1; 3;10;14-after dose (3 hours); Days 17;30;60;90]

      Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. High blood concentrations of uric acid may be caused by study drug, hypothyroidism, kidney damage and called hyperuricemia. It can lead to gout and are associated with other medical conditions, including diabetes and the formation of ammonium acid urate kidney stones. Uric acid in blood is measured in mmol/L. Normal range for the study: ≤480 mmol/L.

      α-amylase is an enzyme that catalyze the hydrolysis of starch into smaller carbohydrate molecules. The alpha-amylase is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine. Both the salivary and pancreatic amylases are α-amylases. Blood serum amylase may be increased in case of the pancreas damage by the study drug. α-amylase in blood is measured in mmol/L. Normal range for the study: 28-100 U/L

    41. Change in Serum total protein [Single dose intake: Screening visit; before dose (Day -1); Day 1 - after dose (3 hours); Days 2;7;30;60. Multiple dose intake: Screening visit; before dose (Day -1); Days 1; 3;10;14-after dose (3 hours); Days 17;30;60;90]

      Protein in the serum consists of albumin and globulin. Protein fractions are determined using electrophoresis. Total protein levels in the blood give a general indication of the state of hydration, nutrition or proper functioning of certain major organs such as the liver, kidneys or bone marrow. Total protein in blood is measured in g/L. Normal range for the study: 64-83 g/L. Concentrations below the reference range may be a sign of low albumin concentration, liver damage, acute inflammation, or a problem of malnutrition or malabsorption of amino acids necessary for protein formation. It may be also a sign of immunodeficiency. Too much protein loss from the kidneys or too much water in the blood can also cause hypoproteinemia. Concentrations above the reference range (hyperproteinemia) may indicate dehydration or an increase in the gammaglobulin fraction, as found in chronic inflammatory diseases, certain viral infections or bone marrow disorders.

    42. Change in Albumin level in blood [Single dose intake: Screening visit; before dose (Day -1); Day 1 - after dose (3 hours); Days 2;7;30;60. Multiple dose intake: Screening visit; before dose (Day -1); Days 1; 3;10;14-after dose (3 hours); Days 17;30;60;90]

      Albumin is a protein made by the liver. Albumin is measured in the blood. Albumin carries substances such as hormones, medicines, and enzymes throughout the body. Low albumin levels can indicate a problem with the liver or kidneys. Albumin in blood is measured in g/L. Normal range for the study: 35-55 g/L.
