The planned study is to determine the safety and pharmacokinetic properties of CPL500036 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 CPL500036 compound in healthy volunteers.
PART A is a single dose, open-label part with CPL500036 compound administered with dose escalation between cohorts.
PART B is a multiple, double-blind part with CPL500036 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 CPL500036 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.

| CPL500036 compound | Drug | IMP is a capsule with CPL500036 as an Active Pharmaceutical Ingredient (API). |
|
| Measure | Description | Time Frame |
|---|---|---|
| Determination of maximum tolerated dose (MTD) or administration of the maximum dose provided in the protocol after single and multiple oral administration of IMP. | 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). | up to 24 hours after single administration of IMP in PART A and up to 24 hours after the last IMP administration in PART B |
| Safety and tolerability of IMP after single and multiple oral administration based on laboratory values, vital signs, ECG, physical examinations and Adverse Events monitoring. | Participants are to be closely observed to assure maximal safety and to collect occurrence of all adverse events. All participants are to be monitored for clinically relevant changes in physical examination, vital signs, 12-lead ECG assessment and deviations from normal in clinical laboratory results (complete blood count, blood chemistry, urinalysis). To follow-up on all study participants telephone calls with a request for information regarding their health condition are to be made. | up to 14 days in PART A and up to 28 days in PART B of the study |
| Measure | Description | Time Frame |
|---|---|---|
| Cmax - maximum CPL500036 plasma concentration | The maximum concentration of the CPL500036 compound in plasma after IMP administration, obtained directly from the measured concentrations. | up to 72 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 in PART B and up to 72 hours after the last IMP administration on Day 14 in PART B |

| Placebo | Drug | matching placebo capsules |
|
| AUC(0-72) - area under the plasma concentration - time curve from time 0 to 72h after IMP administration for CPL500036 | The AUC(0-72) is a measure of total plasma exposure to the drug from time point zero to 72 hours after IMP administration. | up to 72 hours after administration of IMP in PART A |
| AUC(0-24) - area under the plasma concentration - time curve from time 0 to 24h after IMP administration for CPL500036 | The AUC(0-24) is a measure of total plasma exposure to the drug from time point zero to 24 hours after IMP administration. | up to 24 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 and 14 in PART B |
| AUC(0-inf) - area under the plasma concentration - time curve from time 0 to infinity time for CPL500036 | The AUC(0-inf) is a measure of total plasma exposure to the drug from time point zero extrapolated to infinity. | up to 72 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 in PART B and up to 72 hours after the last IMP administration on Day 14 in PART B |
| Tmax - time to reach maximum CPL500036 concentration | The Tmax is time to reach the maximum plasma concentration (Cmax), obtained directly from the actual sampling times. | up to 72 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 in PART B and up to 72 hours after the last IMP administration on Day 14 in PART B |
| Kel - terminal elimination rate constant | Kel is to be estimated via linear regression of time versus log of concentration. | up to 72 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 in PART B and up to 72 hours after the last IMP administration on Day 14 in PART B |
| T1/2 - The plasma elimination half-life for CPL500036 compound | T1/2 is to be calculated as 0.693/Kel. | up to 72 hours after administration of IMP in PART A and up to 24 hours after the IMP administration determined on Day 1, 7 in PART B and up to 72 hours after the last IMP administration on Day 14 in PART B |
