Brief Summary

A double-blind, randomized, placebo-controlled, Phase I clinical study of the safety, tolerability and pharmacokinetics (PK) of ascending doses of XC7 after single and multiple oral administration in healthy volunteers. It's planned to include sequentially 2 cohorts of 4 volunteers who will receive a single dose of XC7 (100 mg and 200 mg) or placebo (cohort ratio 3:1) and 1 cohort of 8 volunteers who will receive multiple doses of the XC7 (200 mg) or placebo during 14 days (cohort ratio 6:2).

Detailed Description

The study will be conducted in 1 centre. The study will consist of 3 periods: screening (7 days), treatment (1 or 14 days) and follow-up (7 or 28 days).

The volunteers of single dosing cohorts will receive the investigated drug (ID) ХС7 or placebo once and stay at the study center for at least 24 hours after the ID administration to monitor the safety parameters and for sampling for PK analysis. The Follow-up will last 7 days, during which safety parameters and PK in volunteers will be studied. Based on all safety data from the XC7 100 mg cohort, the Data Safety Monitoring Committee (DSMC) will consider dose increase and entry of the 200 mg cohort. If the single dose of ХС7 200 mg is considered to be safe, the third multiple dosing cohort of 200 mg will be included in the study.

The volunteers from multiple dosing cohort will receive the ID (ХС7 or placebo) once a day during 14 days and will stay at the hospital (study center) during the first five days after administration of the ID. The Follow-up will last 14 days, during which they will study safety parameters and PK in volunteers.
