Trial Outcomes & Findings for A Pharmacokinetics Study of MK-7655A in Pediatric Participants With Gram-negative Infections (MK-7655A-020) (NCT NCT03230916)

NCT ID: NCT03230916

Last Updated: 2024-02-06

Results Overview

Area under the concentration time curve from time 0 to infinity (AUC0-∞) of plasma imipenem (IMI) was calculated. AUC0-∞ is the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time.

Recruitment status

COMPLETED

Study phase

PHASE1

Target enrollment

47 participants

Primary outcome timeframe

30 minutes (min) before start of drug infusion (DI) and 10 min after the end of DI for all cohorts; 1.5 to 2.5 hours (hrs) and 4.5 to 6 hrs after start of DI for Cohorts 1-4; 2 to 5 hrs and 6 to 12 hrs after start of DI for Cohort 5

Participant Flow

Note: Participant information is shown by age cohort and drug dosage to provide clinically-similar groups for analysis of participant baseline characteristics and safety data. Participant information in pharmacokinetic (PK) outcome measures is shown by age cohort, drug dose received and infusion time in order to provide appropriate and clinically discrete groups for PK analysis and modeling.

PRIMARY outcome

Timeframe: 30 minutes (min) before start of drug infusion (DI) and 10 min after the end of DI for all cohorts; 1.5 to 2.5 hours (hrs) and 4.5 to 6 hrs after start of DI for Cohorts 1-4; 2 to 5 hrs and 6 to 12 hrs after start of DI for Cohort 5

Population: All allocated participants who were compliant with the protocol and had at least 1 post-dose pharmacokinetic (PK) data point available for IMI AUC0-∞

Area under the concentration time curve from time 0 to infinity (AUC0-∞) of plasma imipenem (IMI) was calculated. AUC0-∞ is the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time.

Timeframe: 30 minutes (min) before start of drug infusion (DI) and 10 min after the end of DI for all cohorts; 1.5 to 2.5 hours (hrs) and 4.5 to 6 hrs after start of DI for Cohorts 1-4; 2 to 5 hrs and 6 to 12 hrs after start of DI for Cohort 5

Population: Due to sparse PK sampling schedule, per participant data could not be calculated.

Area under the concentration time curve from time 0 to infinity (AUC0-∞) of plasma cilastatin (CIL) was not calculated. AUC0-∞ is the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time.
