Allocation: RANDOMIZED
Intervention model: SEQUENTIAL
Intervention model description: The dose cohorts were included into the study subsequently based on preliminary safety results evaluation performed by the Data Safety Monitoring Committee. 3 doses of Treamid/placebo (5 mg, 15 mg and 50 mg) were used in the study.The duration of exposure to the study drug was 6 days in each cohort: Day 1, once, at the step of single administration, and then in 6 days, daily, 1 time a day for 14 days at the step of multiple administration.
Primary purpose: TREATMENT

Brief summary: A double-blind, randomized, placebo-controlled, Phase I clinical study of the safety and tolerability of increasing doses of Treamid after single and repeated oral administration in healthy volunteers. The volunteers received the study drug once, and then continued daily intake for 14 days after a 6-day break. The primary objective of the study was to evaluate the safety and tolerability profile of Treamid after single and multiple administration based on the frequency and severity of adverse events and changes in vital signs, laboratory results, electrocardiography and results of the physical examination. The secondary objective of the study was to assess pharmacokinetics of active pharmaceutical substance of Treamid.

Detailed description: 1 Russian center was approved for participation in this study and was initiated. Healthy volunteers were enrolled in 1 center. The study consisted of 4 periods: screening, single administration, multiple administration and follow-up.

All eligible subjects were randomized into the study in appropriate cohort groups sequentially. Cohort 1 - Treamid or Placebo 5 mg once and then daily 14 days after a 6-day break; Cohort 2 - Treamid or Placebo 15 mg once and then daily during 14 days after a 6-day break; Cohort 3 - Treamid or Placebo 50 mg once and then daily during 14 days after a 6-day break. The decision regarding increasing of the study drug dose for a subsequent cohort was made by the Data Safety Monitoring Committee on the basis of preliminary safety results assessment. A total of 16 volunteers received Treamid (4 - 5 mg, 4 -15 mg, 8 - 50 mg) and a total of 4 volunteers received the placebo during the study participation. The follow-up period lasted for 4 weeks.

7. Medical history significant for allergic (including drug intolerance and food allergies);
8. Symptomatic rhinitis in past medical history during 2 years before screening (allergic rhinitis, non-allergic rhinitis or allergic coryza);
9. Blood/plasma donation (from 450 ml) in less than 2 months prior to screening;
10. Surgeries in hospital environment (except appendectomy) during 12 weeks prior to screening;
11. Participation in other clinical studies or taking other investigated drugs during 3 months prior to screening;
12. Inability to understand or comply with the protocol procedures;
13. Acute infectious diseases in less than 4 weeks prior to screening.
