Trial Outcomes & Findings for Comparison of the Bioavailability of Diclofenac in a Combination Product (Diclofenac 2% + Capsaicin 0.075% Topical Gel) With Two Diclofenac Only Products, Diclofenac Mono Gel 2% and Voltarol® 12 Hour Emulgel 2.32% Gel, in Healthy Volunteers (NCT NCT03074162)
NCT ID: NCT03074162
Last Updated: 2019-03-01
Results Overview
AUC0-τ,ss, Area under the plasma concentration-time curve (AUC) over one dosing interval at steady state for diclofenac at day 7 (τ = 12 hours). Stratification by race was analysed using a supportive Analysis of Variance (ANOVA) yielding point estimates for each underlying pairwise comparison analog to the main analysis. As the resulting two Least Square Means and Geometric Means (gMeans) per treatment and race are very similar, only gMeans per treatment and race are presented.
COMPLETED
PHASE1
48 participants
Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administration
2019-03-01
Participant Flow
This was an open-label, randomized, 3-treatment periods (each of which included a multiple-dose period of 7 days \[twice daily and only in the morning on Day 7\] and two pharmacokinetic profile periods of 12 hours \[Day 1\] and 24 hours \[Day 7\]) separated by a wash out period of at least 7 days.
All subjects were screened for eligibility to participate in the trial. Subjects attended the trial site and it was ensured that they met all strictly implemented inclusion/exclusion criteria. Subjects were not to be randomised to trial treatment if any one of the specific entry criteria were violated.

PRIMARY outcome
Timeframe: Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administrationPopulation: Pharmacokinetic Population (PK): This population consists of all subjects in the safety population for whom at least one of area under the plasma concentration-time curve over one dosing interval or maximum steady-state plasma drug concentration during a dosage interval could be calculated for one treatment and who had no major protocol deviations.
AUC0-τ,ss, Area under the plasma concentration-time curve (AUC) over one dosing interval at steady state for diclofenac at day 7 (τ = 12 hours). Stratification by race was analysed using a supportive Analysis of Variance (ANOVA) yielding point estimates for each underlying pairwise comparison analog to the main analysis. As the resulting two Least Square Means and Geometric Means (gMeans) per treatment and race are very similar, only gMeans per treatment and race are presented.

PRIMARY outcome
Timeframe: Pharmacokinetic samples were collected on Day 7 at pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 hours after the drug administrationPopulation: Pharmacokinetic Population (PK): This population consists of all subjects in the safety population for whom at least one of area under the plasma concentration-time curve over one dosing interval or maximum steady-state plasma drug concentration during a dosage interval could be calculated for one treatment and who had no major protocol deviations.
Cmax,ss, Maximum plasma of diclofenac concentration during a dosage interval obtained directly from the concentration-time data at steady state for diclofenac on day 7. Stratification by race was analysed using a supportive Analysis of Variance (ANOVA) yielding point estimates for each underlying pairwise comparison analog to the main analysis. As the resulting two Least Square Means and gMeans per treatment and race are very similar, only gMeans per treatment and race are presented.
