Trial Outcomes & Findings for Bioequivalence (BE) Study of Test Griseofulvin 500 Milligram (mg) Tablets Versus Reference and Dose Proportionality Study of Test Griseofulvin 250 mg and 500 mg Tablets Under Fed Conditions (NCT NCT04318535)

NCT ID: NCT04318535

Last Updated: 2020-12-28

Results Overview

Blood samples were collected to measure Cmax at indicated time-points. Pharmacokinetic parameters were measured using standard non-compartmental methods. For Griseofulvin 250 mg (T2), dose-normalized Cmax (observed value multiplied by 2) is reported. Adjusted geometric mean and standard error have been presented for all treatments. Adjusted geometric mean is the antilog (exponential) of the least squares mean of the log-transformed data. Statistical analysis of pharmacokinetic parameters was done using mixed model for evaluation of bioquivalence. Point estimate and 90% confidence interval for the ratio of geometric least square mean of the test Griseofulvin 500 mg (T1) to the reference Griseofulvin 500 mg (R) were calculated for Cmax to assess bioequivalence.

Participant Flow

This was an open label, randomized,3-treatment,3-period, single dose, crossover study. Bioequivalence between test Griseofulvin tablets (500 milligram \[mg\]) versus reference Griseofulvin tablets 500 mg and dose proportionality between test Griseofulvin tablets (250 mg and 500 mg) were evaluated in healthy adult participants under fed conditions.

A total of 36 participants were enrolled and received study treatment. The study had 3 periods: Period 1 (Day -1 to Day 5), Period 2 (Day 7 to Day 12) and Period 3 (Day 17 to Day 22) with a washout of atleast 7 days (not more than 14 days) between two subsequent dosing days.

Population: Bioequivalence (BE) Analysis Set Population comprised of participants completing at least 2 periods with 500 mg test and 500 mg reference treatments of the study. Only those participants with data available at the specified time points were analyzed.

Blood samples were collected to measure Cmax at indicated time-points. Pharmacokinetic parameters were measured using standard non-compartmental methods. For Griseofulvin 250 mg (T2), dose-normalized Cmax (observed value multiplied by 2) is reported. Adjusted geometric mean and standard error have been presented for all treatments. Adjusted geometric mean is the antilog (exponential) of the least squares mean of the log-transformed data.

Timeframe: Up to Day 22

Population: Safety Analysis Set Population

Urine samples were collected to assess glucose, ketones, occult blood, protein, urobilinogen and bilirubin by dipstick method. The dipstick test gave results in a semi-quantitative manner, and results can be read as Negative, Trace, 1+, 2+ indicating proportional concentrations in the urine sample. Clinically acceptable range included 'negative' and 'trace' results. Number of participants with any abnormal urinalysis parameters are presented.
