Clinical Trial Summary

The objective of this study is to evaluate the long-term plasma and urine pharmacokinetic parameters of Cardionat®, capsules 250 mg, when used in healthy athlete volunteers.

The study consists of four steps:

• Step 1. Screening - selecting healthy volunteers for inclusion in the study;

• Step 2. Assignment in one of the study group, prescription of the study drug;

• Step 3. Samples collections for pharmacokinetic analysis;

• Step 4. Evaluation of pharmacokinetic data.

Description:

Cardionat is a structural analogue of gamma-butyrobetaine - a substance that is in every cell of the human body.

Under extra strain conditions cardionat restores the balance between oxygen delivery to the cell and cellular oxygen demand. Cardionat clears the intracellular accumulation of toxic metabolic products, protecting them from damage; also it has a general tonic effect. As a result of its use of the body acquires the ability to withstand stress and to quickly restore energy reserves. Because of these properties cardionat used to treat a variety of disorders of the cardiovascular system, disorders of blood supply to the brain, as well as to improve physical and mental performance. Synthesis of gamma-butyrobetaine, which has vasodilating properties, is highly increased as a result of reducing the concentration of carnitine.

In the case of acute ischemic myocardial injury cardionat slows the formation of necrotic areas, shortens the rehabilitation period.

In heart failure it increases myocardial contractility, increases exercise tolerance, reduces the frequency of angina attacks. In acute and chronic ischemic cerebrovascular disorders it improves blood circulation in the ischemic areas; it promotes blood redistribution increasing supply of the ischemic areas. It is effective in the case of vascular and dystrophic pathology of the ocular fundus. The drug eliminates functional disturbances of the nervous system in patients with chronic alcoholism during abstinence syndrome.

Pharmacokinetics After oral administration, the drug is rapidly absorbed. Bioavailability is 78%. The maximum plasma concentration is reached 1-2 hours after oral ingestion. The drug is metabolized in the body with the formation of two major metabolites, which are excreted by the kidneys. The half-life after oral intake is dose-dependent, and is usually 3 to 6 hours.

Indications for use:

As a part of combination treatment of coronary heart disease (angina, myocardial infarction), congestive heart failure and dyshormonal cardiomyopathy, as well as part of combination treatment of acute and chronic cerebrovascular disorders (stroke and cerebrovascular insufficiency).

Reduced working capacity; physical stress, including physical stress in athletes.

Abstinence syndrome in chronic alcohol abusers (in combination with specific alcohol abuse therapy).

In this study, volunteers will receive study medication in the form of oral capsules 250 mg.

The study drug will be applied as follows:

• Group 1: intake of study medication capsules orally at a dose of 1 g per day for 3 weeks
• 14 volunteers (7 males and 7 females);

• Group 2: intake of study medication capsules at a dose of 2 g per day for 3 weeks - 14 volunteers (7 males and 7 females).

Study results will be published in "Drug Testing and Analysis" journal

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of Treatment-Emergent Adverse Events	Data collected and assessed for each AE include type, duration, relationship to study drug, action taken and the outcome of the event. Registration of SAEs begins right after the first dose of study drug during the whole course of treatment.	3 weeks after assignment of all eligible volunteers to one of the study groups (day 22th)
Secondary	Cardionat® levels in blood	Test drug (Cardionat®) concentration in blood plasma of healthy volunteers after its oral administration during a period of 21 days (3 weeks) at doses of 1000 mg and 2000 mg (Group 1 and 2, respectively) by a validated HPLC method.	following days 0, 22, 26, 33, 40(twice), 41, 47(twice), 48, 54(twice), 55, 61(twice), 62, 75(twice), 76, 89(twice), 90, 103(twice), 104, 133(twcie), 134, 150(twice), 151
Secondary	Cardionat® levels in urine	Test drug (Cardionat®) concentration in urine of healthy volunteers after its oral administration during a period of 21 days (3 weeks) at doses of 1000 mg and 2000 mg (Group 1 and 2, respectively) by a LC/MS/MS method using a liquid chromatograph Eksigent ekspert ultraLC 100 and a tandem mass spectrometer AB Sciex QTrap 3200.	following days 0, 22, 26, 33, 40(twice), 41, 47(twice), 48, 54(twice), 55, 61(twice), 62, 75(twice), 76, 89(twice), 90, 103(twice), 104, 133(twcie), 134, 150(twice), 151
Secondary	Exercise load duration (Tel)	Exercise load duration (tel) is determined from the beginning of the test until termination by the athlete after the appearance of subjective impossibility to continue to carry the load - testing "to failure."	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	Time of onset of aerobic threshold (Tat)	Time of onset of aerobic threshold (tat) is a time-point of exercise load test where energy supplied primarily by aerobic glycolysis. It corresponds to a level of homeostasis, in which an increase in lactate occurs in the blood, exceeding a certain baseline level (up to this point lactate appearing in the muscles was completely neutralized by buffer systems). It is determined during the test at a value of the respiratory quotient of R ~ 0,85, corresponding to the appearance of the first bend on oxygen consumption-time curve (pulmonary ventilation).	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	Time of onset of the anaerobic threshold (Tant)	Time of onset of the anaerobic threshold (tant) is a time-point of exercise load test where anaerobic glycolysis becomes the leading mechanism of energy supply, and persistent accumulation of lactate with increase of lactate / pyruvate ration in muscle and arterial blood are observed. It is determined during the test at a value of the respiratory quotient of R ~ 1,01, corresponding to the appearance of the second bend on oxygen consumption-time curve (pulmonary ventilation).	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	Respiratory quotient (R)	Respiratory quotient (R) is a ratio of carbon dioxide volume emitted from the body to the volume of the absorbed oxygen during that time. Respiratory quotient is increased during intensive work load effort and lung hyperventilation, when additional previously binded CO2 is released from the body.	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	Maximum oxygen consumption (MOC)	The absolute criterion of achieving the level of maximum oxygen consumption is the presence of a "plateau" on a curve of oxygen consumption from the load power dependence. Indirect criteria of achieving the MOC include: a significant increase of lactate; Respiratory quotient =1,11 increase of heart rate to 180-200 beats/min.	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	The level of oxygen consumption in the aerobic threshold (V'O2AT)	The level of oxygen consumption in the aerobic threshold, AT (V'O2AT) is determined at the time of the onset of aerobic threshold	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	The level of oxygen consumption in the anaerobic threshold (V'O2ANT)	The level of oxygen consumption in the anaerobic threshold, ANT (V'O2ANT) is determined at the time of the onset of anaerobic threshold	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
Secondary	Heart rate (HR)	Heart rate (HR) is registered during the whole testing period (HRres, HRat, HR ANT, HR max, HR recovery), which allows to get the pulse profile, not only for a particular athlete, but also for the contingent of the same sports and qualification level.	following days 22, 26, 33, 40, 41, 47, 48, 54, 55, 61, 62, 75, 76, 89, 90, 103, 104, 133, 134, 150, 151
