Trial Outcomes & Findings for A Phase IV, Open Label, 4-period Cross-over Study to Investigate a Drug Interaction Between Lamivudine and Sorbitol Oral Solutions in Healthy Volunteers (NCT NCT02634073)

NCT ID: NCT02634073

Last Updated: 2017-05-15

Results Overview

Serial blood sample were collected at Pre-dose; 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, 24, 36 and 48 hours post-dose in each treatment period. AUC was determined using the trapezoidal rule. Analysis of variance (ANOVA), considering treatment and period as fixed effects and participant as random effect, was performed using Mixed Linear Models procedure to compare the plasma lamivudine Pharmacokinetic (PK) parameters.

An AE is any untoward medical occurrence, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that at any dose results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect or event that may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition.

Timeframe: Baseline and up to 5 weeks

Population: Safety Population

Blood samples were collected at Day -1, Day 3 of every treatment period and at follow-up. Change from Baseline for AST, ALT and alkaline phosphatase were calculated as the post-dose visit value minus the value at Baseline, at Day 3 and Follow-up. Baseline value used in the analysis was the latest pre-dose values on Day 1 of each treatment/period. Day -1 presented the Baseline absolute values; Day 3 and Follow-Up presented the changes from Baseline.
