ISRCTN - ISRCTN13096283: Trial of safety, reactogenicity and pharmacokinetics of new anti-herpetic remedy Fortepren® in healthy adults

Plain English Summary

Background and study aims
The aims of this study are to run a pilot study of the safety, reactogenicity (potential to cause common adverse effects or side effects) and pharmacokinetics (what happens to the drug once it enters the body) of a new polyprenyl phosphate based anti-herpetic remedy Fortepren® in healthy adults. Fortepren® is a product obtained from fir needles polyprenols and belongs to antiviral remedies with immunomodulating activity (i.e. being able to adjust the immune response to a desired level). A set of performed pre-clinical trials has showed that the drug had no toxicity or any side effects in experiments on laboratory animals and good protective effect in the herpes virus infection model. We want to see if the same can be said for healthy adults.

Who can participate?
Healthy non-smoking adults aged 18 to 45.

What does the study involve
Participants first undergo a physical examination, where their heart rate, blood pressure and temperature at all taken. They then receive a series of Fortepren® injections at a dose of 5 mL (20 mg) administered intramuscularly. After the first injection of Fortepren® , a sample of blood is taken. Blood count, blood chemistry, urinalysis and an electrocardiogram (ECG) are all performed. 24 hours after the first injection of Fortepren® another physical examination takes place in which ECG, heart rate, blood pressure, body temperature, complete blood count, blood chemistry and urinalysis were all measured or performed. Participants are then invited to take part in the second part of the study, which takes place 9 days after the initial injection. If they agree, they are hospitalized for the next 5 days. Each participant then receives a further 5 or 6 Fortepren® injections. The total dose rate of the Fortepren® was 100-120 mg per participant. During the hospitalization, blood pressure and temperature are recorded every 3 hours (except for the interval from 23:00 to 08:00). Blood sampling for pharmacokinetics is performed before administration of the Fortepren®, then after 20 minutes, 40 minutes, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24 and 48 hours after injection. Safety and tolerability is assessed by collecting and analyzing information on adverse events (AEs) and serious adverse events (SAEs) during the study period, as well as changes in the general analysis of blood and urine tests, blood chemistry and vital signs.

What are the possible benefits and risks of participating?
Some participants may experience a rise in body temperature. There are no other risks to taking part in the study.

Intervention

The first injection of Fortepren® was performed 2 days after the screening. On the 9th day, volunteers were hospitalized for 5 days. Fortepren® at a dose of 5 mL (20 mg) was administered intramuscularly. Each volunteer underwent 5 or 6 daily injections. The total dose rate of the Fortepren® was 100-120 mg.
