Healthy Volunteers
Conditions
Brief summary
The planned study is to determine the safety and pharmacokinetic properties of CPL207280 compound after single and multiple (two weeks) administration in healthy volunteers.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Determination of maximum tolerated dose (MTD) or administration of the maximum dose provided in the protocol after single and multiple oral administration of IMP. | up to 48 hours after single administration of IMP in PART A and up to 48 hours after the last IMP administration in PART B | MTD is defined as the highest dose for which no more than 1 of the 6 treated volunteers (less than 1/3) exhibits dose limiting toxicity (DLT). |
| Safety and tolerability of IMP after single and multiple oral administration | up to 14 days in PART A and up to 28 days in PART B of the study | Participants during hospitalization are to be closely observed to assure maximal safety and to collect occurrence of all adverse event. To follow-up on all study participants telephone calls with a request for information regarding their health condition are to be made. |
Secondary
