Safety and Pharmacokinetics Study of CPL207280 Compound in Healthy Volunteers.

One Centre, Single Ascending Dose and Double Blind Multiple Ascending Dose, Safety and Pharmacokinetics Phase I Study of CPL207280 Compound in Healthy Volunteers.

The planned study is to determine the safety and pharmacokinetic properties of CPL207280 compound after single and multiple (two weeks) administration in healthy volunteers.

This is to be one-centre, single ascending dose and double-blind multiple ascending dose two part study of CPL207280 compound in healthy volunteers. PART A is a single dose, open-label part with CPL207280 compound administered with dose escalation between cohorts.Additionaly assessing the effect of food and effect of metformin on bioavailability of CPL207280 is to be done in additional cohort. PART B is a multiple, double-blind part with CPL207280 compound administered for 14 days with dose escalation between cohorts. Participants in this part are to be randomized to receive Investigational Medicinal Product (IMP) or placebo in 3:1 ratio. Safety and pharmacokinetic properties of CPL207280 compound is to be determined following different doses in single oral IMP administration in PART A and different doses of IMP administered orally for two weeks in PART B.
