Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: CPL500036 compound; Drug: Placebo

• Registration Number: NCT03873324
• Lead Sponsor: Celon Pharma SA

Brief Summary

The planned study is to determine the safety and pharmacokinetic properties of CPL500036 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 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.

Arm && Interventions

Group	Intervention	Description
CPL500036	CPL500036 compound	PART A: 7 cohorts are to receive single dose of IMP. Each participant is to take single dose of IMP. There is to be dose escalation between cohorts. PART B: 4 cohorts are to receive multiple dose of IMP. Each participant is to take IMP once daily for 14 days. There is to be dose escalation between cohorts.
Placebo	Placebo	PART B: 2 Participants from 4 cohorts (total of 8 people) are to receive masking placebo capsules once daily for 14 days. There is to be dose escalation between cohorts. Participants are to be randomized within cohorts.

Primary Outcome Measures

Name	Time	Method
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 24 hours after single administration of IMP in PART A and up to 24 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 based on laboratory values, vital signs, ECG, physical examinations and Adverse Events monitoring.	up to 14 days in PART A and up to 28 days in PART B of the study	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.

Secondary Outcome Measures

Name	Time	Method
AUC(0-72) - area under the plasma concentration - time curve from time 0 to 72h after IMP administration for CPL500036	up to 72 hours after administration of IMP in PART A	The AUC(0-72) is a measure of total plasma exposure to the drug from time point zero to 72 hours after IMP administration.
C (1,t) - CPL500036 concentration	Determined on Day 2, 3, 4, 5, 6, 8, 9, 10, 11, 12 and 13 in PART B.	The concentration of CPL500036 on day t before product administration.
Cmax - maximum CPL500036 plasma 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	The maximum concentration of the CPL500036 compound in plasma after IMP administration, obtained directly from the measured concentrations.
AUC(0-24) - area under the plasma concentration - time curve from time 0 to 24h after IMP administration for CPL500036	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	The AUC(0-24) is a measure of total plasma exposure to the drug from time point zero to 24 hours after IMP administration.
AUC(0-inf) - area under the plasma concentration - time curve from time 0 to infinity time for CPL500036	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	The AUC(0-inf) is a measure of total plasma exposure to the drug from time point zero extrapolated to infinity.

C (Tmax, t) - CPL500036 concentration	Determined on Day 2, 3, 4, 5, 6, 8, 9, 10, 11, 12 and 13 in PART B.	The concentration on day t measured on time Tmax which was calculated in PART A of the study.
Amount of CPL500036 in each urine collection sample	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	It is to be calculated as CPL500036 concentration in urine sample times volume of urine collection.
Ae - total amount of CPL500036 excreted in urine	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	Ae is to be calculated as asymptote of the plot of the cumulative amount of drug excreted after each collection interval plotted against the median of the collection interval.
Clr - renal clearance	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	Clr is to be calculated by linear least squares regression analysis on semi-logarithmic transformed data (CLr = excretion rate/C).
Excretion rate	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	Excretion rate calculated as = CLr/V x Dose x exp(-kt)
